The new Medusa 36-70-750v2 motor arrived today!

After I got it installed, that let me establish the final position for the two packs. Lucky for me its right where I put the hatch!

Tomorrow I'll do some full power run ups to see if this set up is what Im expecting. Then, if the weather cooperates, I should get to do a water test Sunday!

With the second pack and the heavier motor Im up to 120 ounces all up - just about 7.5 pounds. Just over my highest guestimate at the beginning - as usual!

Im going to be disappointed if it sinks!

Sorry Larry, but I cant/wont post on RCG any more.

I got permanently banned from RCG because I called the Little Screamers guys, Bob Vincent (Rvincent the shill) and Scott (the owner), liars, fibbers, prevaricators, thieves, cheats, scumbags, degenerates, and, in general, all around bad guys who have bad breath and BO. I had proof of all of that but the last two items

I was actually fairly polite about it - considering that they had cheeted myself and many others and blantantly lied about it, but the senoir Moderator - Jim T Grahm - works for Hobby Lobby and Little Screamers is one of thier main vendors and Hobby Lobby pays a major portion of the bills at RCG.

I got in the way of the money flow and honesty took the hit.

Thanks Chellie! Did you miss the video I posted back in post 76?I re-posted it in post #1.

I will get a new video done with the new colors asap. Im hoping to get some water video soon too but that may have to wait. The pond in those pics is closely surrounded by trees on 3 sides and on the "open side" there are two trees in dificult locations. Id have to make a sharp 90 degree turn imediately after take off and just prior to landing on that pond. On the flight out and back in you have to dodge those other trees.

I have no problems with BUFY or any of the Capricorns but this plane likes to fly a LOT faster.

I want a few more flights under my belt to get a better feel for the low speed handling before I try that with this bird

I think I need a signature.

Here are the last of todays pics.

The plane is now a little more than a pound heavier than before but it still flys great! The CG is about 1" more forward than before and I want to move it back. It takes noticably more down stick to hold inverted.

I ran the new system up with a 12x6 prop and was drawing about 64 amps at 1060 watts at 11,200 rpm on the cold 6S2P A123 pack. That was about 30 seconds into the run with the packs still cold at around 45 degrees.

It flew nicely but still didnt quite have 1/1 thrust and the speed still felt a tad slow.

Everything came down barely warm after the flight.

I switched to the 13x6.5 APC E and got 75 amps at 1265 watts on packs that were warmed up after the first flight so they held a bit better voltage.

Much better. I now have better than 1/1 thrust but not by a ton. It will climb straight up forever but its not a rocket. Good enough.

Speed is better but still not as fast as I was expecting. I may try a 13x8 down the road a bit. The packs will handle the draw easily but I'll probably be pushing the controller and motor a tad. If Im not much over 80 amps I may go that way just to have the extra oomph once in a while

Two flights on the 13x6.5 set up and the motor, esc, and packs came down slightly warm. Perfect!

The water tests went very well. I did a lot of hi sped taxiing and turning and going slow and stopping and starting. I got zero water inside - no leaks - and no water got into the air scoop or the servo slots in the tail

The only down side I can see is the turning radius on the water is pretty large. It turns much larger circles than my Capricorns. In one picture below you can see where I didnt start the first turn on the pond soon enough and ended up on a log against the shore! I was just able to reach it with a stick and push it back out.

I need to add a drop down water rudder I think. The main rudder is cut a bit too hi as it sits now. I did that on purpose so it wouldnt drag on land. Ive gone thru a lot of servos that way

Hi speed steering when "on step" is excelent but still rather large turning circles.

Im comparing this to my Mega Capricorn which is a little unfair. The Mega has a rudder thats 5 times as large

Im going to move the step back once I get the CG finalized so that may help with the 'at speed' stearing.

Im not too worried about the turning circle though. This isnt really a small puddle flyer any way. Certainly not to the degree the Capricorns are.

I was mentally comparing it to the Mega Capricorn all day but thats not really fair. They are apples and oranges.

In most ways the Mega handles on the water better - much better actually. Its also easier to fly, take off and land - mostly because it can do all of those things much slower and in a much smaller amount of space and it has a huge amount of built in stability in almost any attitude. The Mega is more agile and far more manoverable too.

Its not that the Polaris flys badly at all, its just that the Mega is in a class by itself.

BUT... when you put the two side by side the Mega is kind of the ugly duckling in comparison. The Polaris is soooo sexy and looks soooo cool in the air that it pretty much balances all the rest out

If I could only have one - Id kick and scream and hollar and choose the Mega, but you'll have to fight me to give up the Polaris

Hi Larry and Larry On the Polaris props, May i suggest trying a wood nitro prop, I have gone over to Nitro wood props on my larger motors, and they seem to work much better than the plastic APC props, lot more thrust and power, I like the Zinger wood props, I belive Zinger even makes a wood e prop, but I like the nitro props better every one i have told this to, has tried the wood nitro props and agree, Just My 2 cents worth, Take care, Chellie

I have been meaning to try some glow props on my larger planes but havent gotten around to it yet.

Zinger has a couple of pitch sizes that APC doesnt so I may just try one on the Polaris.

Thanks Chellie!

I was thinking of maybe trying that on my giant Pitts, but didn't know what to expect. Now I will definately try it.

I will start a thread here as soon as I get to feeling a little better. I really would like to see that stagger wing jet fly. You might just be the man to find the problem. I will appreciate any help you can give.

I got several more flights in on the XXL Polaris today - sorry no video!

I am likeing it more every time I fly it

I moved the CG back some more today but it needs to go back more yet. It still needs a good bit of down to hold inverted. I may have to move my battery hatch so I can move the packs further back.

I discovered today that it spins much better inverted than up-right but still not very well. It may be my technique but its probably mostly a CG thing so I'll try some more after I get the CG back further.

I also discovered that it does an awesome 'Lomchaveck' maneuver. For you 3D guys it looks kind of like a 'wall'. Kind of cool looking! Its important to go easy on the elevator in hi speed turn though or you will get a 'departure from controlled flight'

I did a lot of slow hi alpha flight today. Trying to see if I could fly it off my small pond.

Its not anything like as good as the Capricorns but its not bad. It slows down nicely with some wing rock but its easily controllable. I think my having the ailerons work as elevons helps the wing rock because I get reflex when I give UP elevator.

The trick is to maintain forward speed at all times though. If the speed drops off too much it will abruptly stop flying and start to waffle down towards the ground! Fortunately I have enough power so that all I need to do is goose it and drop the nose a tad and its flying again. It doesnt drop a wing but it still eats up some altitude so you need to be carefull.

Im still not going to try it on the pond untill I have a lot more flights and a better feel for when the stall occurs

I think I need a signature.

I posted some thoughts in the thread. Hope they help!

I have found a couple of weak points in the design that you may want to address in yours Larry.

I should say its not any weakness due to poor design on Steve's part but a material weakness. The blue foam is not great for hi stress areas and a few places are needing more attention on my plane.

I flipped it over tonight to start the process of moving the step further back and thats when I saw that the foam at the step is showing signs of compression. If you only ran on the water it would not be an issue but I will be flying of grass/pavement more than off water. I decided to add a vertical Ply piece at the step. It will rest on another ply piece to spread the load out along the underside of the tail section.

That tail section is the second area needing attention. I found a number of holes and scratches and divits caused by running over rough grass/ground. The area at the very rear is ok where I had the super slick tape applied. That stuff is very tough.

I was just going to tape over the rest of the underside of the tail but then I found the third problem area.

On the top side just in front of the ply plate the motor/rudder mounts to there is a stress crack across the wing section. Its right exactly where the ply plate stops. There must be a fair amount of bending force at that point.

So... I decided to glass the bottom of the tail section and the top center of the wing at the rear to spread the loads out some more and stifen up the tail section in that area. It would have helped if I had made that plate cover more area extending it more forward.

I think I need a signature.

Had a great time at a fly-in at the lake Sawyer Hawks field yesterday.

It was crazy windy but I flew the Polaris several times anyway. Turns out it handles the wind very well. The new step location seems to work well on the grass so Im anticipating good water habits.

The Polaris got a lot of attention. Two fo the guys told me they had voted it the un-official best of show

Most of the guys had never seen a foamy that big and they were surprised at the power and performance in flight.
