I picked up this plane by accident. Actually, I ordered a few planes from my buddy who owns a hobby shop. One Saturday I saw the Sportster sitting in his car while we were at the field. I asked him who ordered it, and he said "you did". So, I picked up the plane and looked it over. I knew I was thinking of buying one, but for the life of me I didn't remember ordering it. So, I paid him for it. I then told him to cancel the Goldberg Chipmunk I ordered. Then he said, "Oh! Thats right, you ordered the Chipmunk" He aplogized and said he'll take the Sportster back, and I told him, "Over my dead body!:eek: :mad: "

So, now I'm trying to decide if I want to use the stock motor, or go brushless. I was hoping those who own this bird, or have seen them fly, can pitch in with some conversation about this great aircraft. I own a Mini Sportster, and I love the way it flies. A guy at my field used to fly the Super Sportster. He flew it stock for a while, then went with a 2808. But he crashed on the first flight with the Axi.I think it's a great plane. (Pardon the pun):rolleyes:

Please chime in with hints, suggestions, rants, humor, or whatever.:)

There is a lot of good talking about this plane in this thread:
http://www.wattflyer.com/forums/showthread.php?t=182

They have just good words for the mini, so I think you could find answers there.
I will follow up too, here because I was looking at buying that Super Spotser Ep from Tower Hobby :D !

So I need to check what E motor I will be putingin too :rolleyes: .

Thanks. Actually, I participated in that thread. The Mini is an awesome plane. I'm thinking of getting a lipo friendly speed controller and flying with the stock motor and lipos. I'm moving soon and I really don't want to pour more money than I need to in my aircraft. I have a pattern plane that I'm going brushless with. I'll definately upgrade the SS to brushless in the future, but for now, I just want to be able to fly it.:) Then again.;)
Thanks all.

I have the 48 inch EP version that I fly with an AXI 2212-34 SWINGING A 11/7 PROP @ 5000 RPM on 3s1p with polyquest 1500 & 1800 ma

12 to 15 min flights are the norm, takes off from grass just fine and loops from level flight, only real limitation is that there isn't any vertical performance and climb outs are gradual

A very enjoyable plane to fly!

I have the 48 inch EP Sportster that I fly with an AXI 2212-34, 11/7 prop @ 5000 rpm, 3s1p Polyquest 1500 & 1800 ma with typical flight times of 12 to 15 min @ 7 to 8 amps, AUW = 28 ounces

Take off from grass is easy, loops and rolls from level flight right up to the end of the pack. NO VERTICAL and climb out's are gradual at about 25 to 30 degrees

All in all this is a honest flying plane that flies on the wing at about 45 mph

Flew it once with an AXI 2808-26 and it was a blaze of power but very AMP hungry with a 9/6 prop, 12000 rpm 20 ++ amps that overheated my CC 25 esc 3 min into the flight causing shutdown

Went back to the 2212-34 but would like to try the 2212-20 with a 9/6, should do well at about 16 amps,,mabe.

See if you can get the EP with out the included power system as it is very heavy and a waste of resources IMO

cHECK YOUR lhs TO SEE WHAT IT MIGHT COST TO DO IT WITH REPLACEMENT PARTS oops, CAPS!

For instance I can get the Parkzone P 51 AS PARTS for about $75 USD instead of $189 for the whole thing including radio that I would not use.

It was just a thought aimed at saving you money that you may not need to spend

My best friend has one flying with the stock power system, and it does very well.

He has recently changed to a 3S LiPo to lighten the plane, and propped down to a 11x7.

I would at least try the stock system since you already have it.:)

Yes, he switched to a 30A LiPo sensitve ESC. I just can't remember which model though. It shouldn't matter as long as it is a 30A.

I fly my friends and he built it stock with nicad battery and it will do all the sport acrobatics and has a wonderfully long glide when landing. I am very impressed with this plane for sport flying. We did lose the stock ESC and went with a Jeti.

Have to smile when I read about GP's NEW! EXCITING! electric Super Sportster

Way back, not long after I landed on this continent, I was out flying at the old DCRC grass field (since dug up for a wildly unsuccessful and costly 'Soccerplex") when this guy shows up with a SS.

Nothing remarkable, back then, GP made great things called 'kits' that came in three sizes of most of them, and the SS was available and widely flown in 20, 40 and 60 versions. This one was a 20 sized version, but with no big ugly jug sticking out the top of the nose end.

Ed Sweeney was the owner - he'd bought it ready made from a clubmate and fitted an Astro 05G, a top hatch and a tray for 9 cells. This was in the days when the SCR 1200 was the top dawg cell, BTW.

I'd had electrics for a while then - mostly "snoarers" in the "Seven Cell Trap" bracket. You remember them - hand toss launch, set a timer to check they ever got high enough for a loop. Yet here was a good looking low winged aerobatic ship that taxied out across the grass, took off easily, acted like it looked for long enough and taxied off after landing.

Ed had got his SS at a club bring and buy, and fitted the AF05 himself, so I guess that made it a BARF. It sure had a hefty feel to it - GP structural designers usually can't spell 'weight' - but it sure flew fine. THe UC was out in the wing, a couple of rib bays from the fuselage, looked neater than the present fus mounted gear.

So, from my memories of that model, my first suggestion would be to use the supplied motor as a paperweight, fit either a BL or at least an Astro 035 or 05 Cobalt, get inside the fuselage and fit (in ascending order, if they'll fit) 10 x GP3300, 4S 2P Saphions or a 3S LiPo. Then you'll have a model that won't have to make excuses to anyone. I'd aim for 400W - an Astro 05 BL with 3:1, propped to 40A will do you nicely.

I happen to have an AF05G someplace that I'll likely never use again - could be persuaded to sell it ... Personally, can't see the point in a model like the SS with GP's eight cells into a ferritte lump - just not enough power to make a model like this act like it should.

The GP SS-E is another fine examples of "ARF" - Almost Ready to Fix". Occasionally wish I could find a plan for the old slimer 20 version - it would electrocute nicely if done properly. It's amazing how well a 50oz model can go with 400W in the front ... Must finish up my latest ten cell plan model and do it again sometime.

Hope that helps

Decided to go with a Mega 22/20/4 With a 45 amp Phoenix ESC. I got the ESC new for 72.00:) . I'll use HS81's throughout and two Tanic 2100's. This setup should turn some heads. I think the SS ARF kit is solid. My only fear is that after flying a larger plane, I may not want to build smaller ones anymore.:(

You won't!

If I could have only one "outdoors" model, it would be my Four Star 40 - or
"Five Star 16" as it's affectionately known, due to the teensy-weensy range of modifications I've done to it.

And if I couldn't have one that big, it would be my "Own Design" ten cell variant! This is approx the same size as the SS20, but better than 75% of the weight.

Your set-up should make your SS act like it looks - have fun

Hi Steve

My son and I have been flying our Sportster EP stock and really enjoy how capable this plane is. Even stock, the sleek air frame can make for some heady speed and excellent climb. Vertical is there with a bit of a run and wait till you try a snap roll :eek:. Your set up will be much lighter than ours with the stock motor and 7 cell 3300 batt. not to mention the power you will get with the Mega. This plane is a bit twitchy, as well as nose heavy and carries lots of speed on landing. At least with your set up, you should be able to remedy the nose heaviness easily. It is our first low wing plane so quite a learning curve. Very forgiving behavior, but can do IMAC like moves as well. You will have major fun ;).

Thanks JC:) I fly the Mini sportster now. I really love the little guy. It's a superb flyer, even in wind. I sometimes fly it in 10-15 mph winds. Sure It will bounce a little, but boy it's a blast! I'm thinking It's big brother will be more of the same, just more stable. I'm hoping to maiden her this Sat.

Roger aka GIFLYRC

If you take that setup, and go with a 10x5 prop, your amps will drop exponentially. I tried a 9x7.5 and had 40+ amps. I put on a 10x5 and the amp load went to 29.

As New2RC knows from my postings at RC Groups, I have installed a Great Planes S-600GD Motor/Gear Box system in my new Super Sportster EP. I am using the included 15T pinon gear for a 3:1 output ratio. It also comes with a 1/4" prop adapter which I use and a 9X8 prop which I don't use.

After burning out the included 30Amp ESC in my Super Star EP I also replaced the ESC in the Super Sporster with a Great Planes ElectroFly 55Amp LiPo friendly ESC. I have not checked the total amp draw of this set up but I havn't burned up the motor yet.

I also am flying with a APC 12X10-E prop and a different prop spinner that
allows me to set the motor as far back as my finned clam shell motor mount will allow and still have the spinner almost touch the front of the cowl.

To help with the nose heaviness of this plane, I mounted Tower Hobbies micro metal geared servos to the rear of the servo mounts by gluing another piece of light ply at the rear of the servos.

I decided on the metal geared servos when I read that some were stripping the gears on their standard servos during some extreme manovers with the Sportster!

I have an 8000 mAh Thunder Power 2s4p battery that I was using on the SuperStar EP that I am also using in the Sportster. It is lighter than the 2100 mAh 7 cell Great Planes Nicad batteries that came with the SuperStar and Sportster and gives almost unlimited time in the air!

Using the 8000 mAh battery, I have had many 20-30 min continuous flights and the most power I have put back in the battery is 5400 mAh, which is close to 2/3 of the total battery pack. Never had a low voltage shut off and the lowest volts at recharge has been 7.4Volts. During the entire loonnngg flights, there was only a slightly noticable reduction of prop power and this was usually after about 20 min of flight. Costly battery but terrific performance!

Even after these long flights, mostly at full throttle, the motor comes down warm, battery only slightly warm and ESC just warm, just an amazing match of resources!

I am still learning to fly the Sportster with an instructor and a buddy box and have mastered some interesting manovers (Some which have no official names, because of my "dumb thumb" twitching) and some real manovers including of course, loops, rolls etc. but landing is still a real thrill and I usually have my instructor do that. I tried landing last night after several low-slow flybys and managed to hit the tall grass just off our grass runway and flipped the Sportster over. The only damage was cracking the motor mounts just behind the clam shell mounts.

I repaired this with 30 min epoxy and they are stronger than new. This may be the weakest part of this plane since there is not a lot of support for the motor mounts in the stock configuration. I am trying to engineer some more support for the mounts and will post them here if I am successful.

If you have decided with a Brushless setup then, please disregard my suggestion to visit my thread at:

The above shows the Kyosho Endoplasma 16-turn buggy motor in geared form. Another motor that I had very good success was the Great Planes "S-600GD" power system (EPIC motor in Great Planes packaging).

Thanks for your info. Unfortunately the plane met it's demise. I went with a Mega 22/20/4, CC 45A esc, TP 2100 3S Pro Lite X2 in Parallel. It flew very well with a 10x5 prop. A friend suggested that I go with a 9x6 for more speed. I did and it was much faster. In fact it was too fast. It experienced sort of a terminal velocity. The elevator ripped off and she went nose in.

The motor was buried 3" into the gorund!:eek: Can you believe that same motor now pulls my pattern plane? Unreal! I've since learned that not all aircraft were meant to go at warp speed. The next time I'll pin the hinges. I may buy a new one. It was such a great flying plane.:)

Hi Claude

She will fly very well stock, but the Nicad pack that comes with it is marginal at best :rolleyes:. You will get around 5 to 6 min. with it.

We still fly ours stock but use GP 3300 7 cell packs which make a major difference. The 3300's are becomming difficult to find, but I have read good things about the Elite 3600 batteries from CBP (they are always out of stock on these cells). That is where we bought our GP packs from and they have been great. Here is the link for the Sportster. Their site has a very cool search by model feature. You can select a pack configured like the one supplied with the plane using a cell you like. They also sell lipos if that is your preference.

http://www.cheapbatterypacks.com/main.asp?sid=547777&pgid=superlisting&type=airplane&manufacturer=9&model=96

Best of luck with her ;). The plane will be quite nose heavy unless you mod it to move the pack aft.

What's you guys flight weight with the stock power setup? I just finished mine and she's at 3lb 3/8oz with the stock battery and it looks like i'll need up to 3oz of weight to balance her out which will, according to the instructions, put it right at the recommended 3 1/4lb. Just curious what you guys with the stock power/battery are weighing in at.

Thanks!

First flight with the stock set up was a disaster. Rebuilt one section of wing and some of the Fuse. Assembled with a E-Flite 25, Electrifly 45 ESC and Apogee 3 cell Li-Po, 2500mah.
For the first flight with this package I used a friend who just happens to be an expert pilot.
This thing is incredibly fast, instant take offs and great balance and handling.
It flies great at 1/2 throttle.
Because of time constrants and a large crowd at the field, we will do the rest of the testing and adjustments at a later date and I'll be sure to give y-all a report.

You make a very good point here. I have seen at least a half a dozen posts describing upgrades to high power brushless systems with this plane...with the same end result as yours. 48" may seem big for an electric, but it is still quite small when you double (or more) it's power and speed from it's original design. Couple that with the fact that you are normally going to be inclined to fly a smallish plane closer to the ground and you have a recipe for disaster if anything goes wrong.

I'm thinking of buying one of these, flying it stock for a while, and then maybe upgrading the ESC and battery to a Lipo system. My main concern is, will I be able to ROG on our somewhat primative grass field? Anyone had experience with this, and btw, putting a $300 brushless setup in a $99 plane is not an option I care to pursue. I'm mainly interested in experiences with the stock power system with the 2100 and 3300 battery packs, of which I have several that I got for my Superstar EP a while back.

Dereck

I hate to sound one-up-ish, but I've been putting BL set-ups of around 300W into 48"-ish span models that cost a lot less than $99.00 for years now.

Seems a lot of these models have lost valuable parts in flight - this suggests that there's a QC issue here, as ready-mades should be absolutely perfect for their design spec - and losing a tailplane suggests perfection is a ways off.

How is said stab fastened in? Mine are glued to not only the fuselage sides, but to a plate between them that starts right at the back and continues to a half inch in front of the tailplane LE - stress risers are to be avoided at all costs. The fin with its attendant gusseting deals with the topside of the tailplane, deriving its necessary strength from its solid base on the tailplane.

Basically, if you're going to buy ready-mades where you can't look inside to check on structural integrity and you put a worthwhile amount of power in them as opposed to the trivial amount of power the airframe was designed to take, it's your investment on the line.

Can't imagine flying a model that size with anything less than 300W and if I got a flying weight of much over 3lb, I'd be asking my personalised design/build service was it was pratting around at ::o

The GP Sportsters have great aerodynamics and a long history of delivering great flight performance. If I had anything like spare time for suchlike, it would be interesting to get hold of the plan for the 48" version - RCM may still sell the original 20 glow version plan - put a decent structure with battery hatch, taildragger on the fuselage and other such good stuff inside the shape and a decent BL on 3S on the front. Bet you'd have a great sports aerobatic that would do a lot of pattern aeros and be a *****cat to operate off a typical club field - plus it would fit most cars, even in one piece.

Hey there everyone...maidened mine this weekend. I picked up 2 4500 maH packs from all-battery.com for $50 for both. Flew it for 3 flights on each pack with no recharging...it does have enough power to fly fairly well stock. Rolls are a little anemic though. But it does everything you need it to. Carlo's mods are awesome, the thing just screams! For me though, I prefer my more relaxed version...nice long flights that are just great fun!

I don't have any experience with the SS / electric jobs but I had the SS-40 with an Enya 45 and it was the best plane I ever owned. With the CG about 1/2 inch behind the suggested location it would flat spin, knife edge and snap better than a Chipmunk. As a matter of fact it died in a flat spin because I got so caught up in how pretty the spin was I forgot to look for the ground. DAMN I miss that plane. Anyway I still have the original plans and the assembly manual. Everything suggest that the 20, 40, and 60 plane were the same except for overall size. There are plenty of areas that weight could be lost without danger. The only fragile part of this plane was the wing mounted landing gear and some fiberglass solved that. That plane was a tank and flew like a butterfly. If any of you want copies of the planes and manual email me at didit_myway@hotmail.com and we'll see what can be worked out to cover the mail or shipping. I'm not worried about the cost to reduce or enlarge the plans. I already reduced a copy to a 30 inch span as a possible future project.

let me know how that beast does. Should put my power10 to shame. I just bought a new Reactor and set it up with factory specs.
I used a Rimfire 3530 -950 KV. I flew it this am and it could use more power. other than that the plane flys good. bentoad

We finally got this turkey off the ground and it aint no turkey!!!!

The stock power system never worked. The ESC kept shuuting down from power overload. It took forever to take off and then would alway cut out. The plane is too cool looking to give up on so I shelled out the money for a Eflite power 15, Tbird 54 ESC, Polyquest 3S1P 11.1V 3600mAh 12C lipos, APC 12x10E prop.

The plane screams!!! very little runway room is needed 1/3 throttle and it will fly forever. I do not fly as well as my son and tend to use my planes as flight simulators. I tried to land and cartwheeled the plane...some cracks in the fuse behind the wing and a broken prop.

I put on the new prop and my son flew the pants off the plane. Rolls loops stalls!!! He landed in some tall grass as the prop broke......no big deal.....he accidentally bumped the throttle and the off balance prop ripped the front of the plane off at the fire wall.........I told him don't worry we have plenty of 5 min epoxy at home. I will have it repaired and ready to go again for tomorrow. I love this plane!!!!

I think the prop might be too big.....any suggestions?

APC 12x10E prop.

Try an APC 9X8 "Sport" prop, and hold on to your transmitter:eek:!

It will go about 75+ mph but you should a piece of 1/4" flat carbon fiber to strenghten the bottom of the horizontal stabilizer at these speeds because several Sportsters have cracked and broken the horizontal and crashed. I caught mine before crashing when a fellow flyer heard it fluttering as it passed overhead.

The 9X8 is the best prop for speed with the Sportster.

We have a few more props to break before buying new ones. My son is addicted to speed. :blah:

I already put the front end of the plane back on with epoxy. We are ready for more flying tomorrow.
