I just finished a Mini SpeedWing 250. This one I powered with one of those MTM (JustGoFly, etc..) 300DF Outrunner motors. This motor is just over half the weight of the Johnson 250 and only pulls 5.9A swinging a 4x4 prop on 3s LiPolys.

This light motor, because of the lower amp draw, let me use light weight batteries. So now I have a MSW 250 that only weighs 6.8 oz. With this setup the wing has full vertical and speeds about that of the MSW 250 with the stock motor (only pulling about 2-3 amps less).

The little I have flown this wing, the motor seems to be really good for the money.

Acer - give her more juice. The 300DF can handle alot more than 5.9 amps - about double that. Try a 6x4 for more thrust or 4.75x5.25 for more thrust and speed. I like the 5x5 on my Pocket Combat Wing - which is more like a Pocket Rocket. Actually it may be a little too ballistic but definately gets the blood flowing. I brought it to Ireland with me since it packed nicely and flew it often. The birds never saw anything like it and decided to pick a fight with the speed demon - man it was a blast having a flock of birds chasing my plane around the field. I'd slow up and let them catch up - gun the motor and climb around in a loop and get behind them. You never saw such a ruckus. Fun stuff.

Vinnie, thanks for the heads-up. I'll try the APC 4.75x4.75 and 5x5. I'll need to use a little bit larger batteries to handle the amp draw, but the speed should more than make up for it :)

Right now with the 4x4 prop and 3s 830 Tanics, the speed is around 60-65 m.p.h. How fast did your wing go with this setup?

-- Acer

Acer - you may be setup perfectly for your plane. I'd hate to wreck that. It doesn't make sense pushing the speed up and running less efficiently at a lower throttle setting. The speed on the pocket combat wing was just short of insane. I don't remember being able to gun full throttle for more than a few seconds. The climb outs were extremely impressive and fast. I did use a 1200 mah 3S, but am considering doing as you are which is to go to a lighter 850 or even 2S. I think I need less weight on the PCW, since it needs to remain fast to stay airborne. I'm still working on some quirks that I think occur due to the weight.

I never measured the speed of the wing so I can't say how fast it is.

Nice setup and have fun ! How about a video ?

Thanks Vinnie. Yes, my wing is set up great at the moment. It is still very light, so it can glide extremely well and you can fly it in close-in spaces (it's very easy to fly it in a ~10 foot circle around you doing flips and loops).

BUT, it is very easy to chage a prop and velcro on a larger battery :D My wing has a wing area of 167 sq.in. so it handles weight very well (can still hand catch at 10 oz.).

Deffinitely going to try it!

BTW, do you have the pusher version of these motors? Right now I am using the tractor version. It would be easier to manufacture a mount for the pusher version (i.e. the motor shaft comming out from the spinning can side instead of the back plate)

We definately have 300DF pushers and bells to convert a tractor to a pusher.

Thanks Vinnie, those look like the ones I need:)

Well, I tried an APC 4.75x4.75 prop on the 300DF MSW 250 :) I'm still running with the 3s 830 Tanics and the prop pulled 7.8A. I went out back and did a quick flight and radar check. It clocked in at 72 m.p.h. in level flight! The motor was cold after I landed, so it can handle ALOT more current.

Since I'm at the amp limit on the batteries, I'm sure it would be a little faster with a larger pack. I'm going to see if I can get this wing near the 100 m.p.h. mark with this motor (it might take 4s to do it, but it would be fun).

I saw your motormount and I wondered if this is the stock or have you built that yourself? I want one to, hehe.

I'm also very interested in that mount. I want to try my 300DF on my Mini Bird of Prey. I like the way this mount keeps the motor on the centerline.
What do you think about this Vinnie? I could drop the 2100mah pack for a 1320 and loose some weight. It's presently setup with a 10 turn Astro 010 and it's pretty dadgum fast. I'm sure my wicked little 300DF will make it a missile. I need to order up a pusher bell for it though.

This 300DF motor has been absolutely amazing. I smashed it into the ground at probably 60 mph in a MiniStick and all it did was break the shaft. I installed a new shaft/bell in about 10 seconds and it still runs like new. I thought for sure it was a goner. I usually run it close to 10 amps static draw too. It never whimpers. This is good stuff Vinnie!

The motor mount is a modified mount of the stock Mini SpeedWing 250. All I did was enlarge the opening a hair and epoxy a motor mounting plate to the back. With a pusher motor, you'd mount the same plate, but it would be mounted towards the front of the motor cutout.

I'm going to be designing a mount just for the 300DF in the MSW 250 pretty soon. BUT, it is very easy to do yourself if you want to.

A friend of mine came out to the flying field last week with an EPP packing foam that was used to ship a computer. He said he was going to make a wing out of it. He showed up a couple days ago with this absolutely gorgeous 34" wing with a short root cord. We put a 300DF pusher in it - tossed it in the air and I'll be damned if it didn't fly just so beautifully and FAST. We figured 60-70mph wide open throttle. He is using the 1300 mah batteries and is getting 12 minutes. I was impressed that a guy just read some of the details on how to make a wing, made up all the tools and made a gorgeous wing that flys mint. We flew it again today and learned why we use stapping tape. In a high speed dive from very high it fluttered and catapulted the battery out of the wing. We walked the field for 30 minutes and three of us couldn't find the battery. But plane is undamaged short of a rip in the light covering.

Anyway - 300DF was perfect for this fast wing, anything bigger would have just added weight and 70mph is very fast.

If you have the possibility to make/buy a mount and modify it for the 300df motor I would gladly pay you for it. I have tried several mounts for my wing but so far I have not gotten my hands on any that works/look that good like the one you have posted a pic of.

Acer

Iceman, do you mean to go with a MSW 250? If that is the case, I can build a mount for you for $5.00 extra if you buy the MSW 250 kit.

I already got a MS Compositwing that I keep on braking the mounts on almost every landing, and now I am fed up with that. If buying a new MSW250 is what it takes I might buy that and a extra mount for a 300df motor. What would the price be shipped to Norway?

Acer

10-31-2005, 12:34 AM

I really couldn't build a mount for another wing since this mount is specifically made for the MSW 250's thrust angle, airfoil and root chord (it wouldn't fit your wing right). Did you want 2 mounts (1 made for the 300DF and one just normal)? If that is the case, it would cost $5.00 for the extra mount, $5.00 for converting the MSW 250 mount to 300DF, and the cost of the kit.

Shipping to Norway costs $12.00 via Air Letter Post (4-7 days).

If this sounds good to you, let me know.

That sounds good. I have got the 300df in pusher mode and what kind of lipo battery will this MSW take/carry and at last What will the total be?

Acer

10-31-2005, 01:01 AM

I'll PM you the specifics. The MSW 250 can carry up to 3s 1500mah LiPolys. On mine, I'm using 3s 830 Tanic packs. You can keep it light with smaller batteries and use a smaller prop like the 4x4 or 4.75x4.75 which makes the wing fly very well and have a very flat glide. OR you can load up on the batteries and use a large prop for all out speed, this will of course affect the glide and how well it can slow fly.

PM and money sent via Paypal, cant wait to get my hands on this one. Do you suggest to cover it with plasticfilm or do the packingtape method make it strong enough?

Acer

10-31-2005, 02:31 PM

Will be shipping today! I suggest covering with Econokote using low heat. You can use tape as well (same strength as Econokote), but it doesn't look as nice.

Well, we flew it again today and took some video. The radar reading we got was a constant 75 m.p.h. using the APC 4.75x4.75 prop and 3s 830's at 7.9 A. I tried it with some 3s 1500's, but even though the amp draw when upto 10A, the speed stayed at 75 m.p.h. I may need to go to a larger pitch prop to get the speed above this level. I'll also probably try 4s.

We'll get the video edited and up in a day or two. I'll let you know when it is ready.

P.S. here is some in-flight pics of today.

I received the wing today and it looked like it would be a lot of fun with this smallsize wing. The motormount you made for me for the 300df also looked very good. Now I am only awaiting some HS55 servos to go into it. Cant wait to get this in the air with the 300df motor a Apc 5x3 prop and a PQ 3sp 1100Mah lipo battery. This will go like a rocket, hehe.

I am building ong right now to try and catch the tips on fire! :D I am going to use a specialy wound Littlescreamer for this on 2 cells with a 5100kv rating spinning an APC 4.75x5.5 prop with a 1320PL. I am hoping to get 85+mph :D

I dig the fast stuff! :D Anxious to get my hands on some of your motors too Vinnie :D

The MSW is now finished and ready to go. I have propped it with a Cox 5x3 propellar and it seems very promising with better than 1,5:1 in thrust. It may not be a 100mph wing, but it will do everything with half throttle. Cant wait to get it in the air. Still waiting for some better weather for the maiden, because here in Norway it is still to cold for everything made of foam.

Acer, I have only been practicing on my GX3 simulator,and have no real flying exp. and I just purchased a J-3 PZ and also a DX6 spectrum, my question{after viewing your web videos} is ,can I use the DX6+servos in your mini wings. I was really impressed with the slow speed manuverability and higher speed as well. I`m completely new at this hobby and I think I can handle your mini wings. What say you?

Acer

12-21-2005, 10:21 PM

USOPA, the servos and receiver look like they should work well with all but my Micro SpeedWing. If you are new at this, I recommend the regular Mini SpeedWing (the one with the EDP-50 XC motor). This wing will fly slower than my other mini wings, so it makes for a better trainer. On low rates (low control surface movement) the Mini SpeedWing has trained many people to fly.

It will also fly up to around 40 m.p.h. with the stock motor, so once you get better at flight, it still remains a fun wing to fly.

Best of all, it is very tough, so it can withstand countless crashes with VERY little to no damage (almost all cases no damage)

Let me know if you have any other questions.

Hey Acer, and people. Just wanted to chim in with what a great product the SpeedWing is. I had a MSW 250 with the stock motor and went with NiMh batts (because I didn't have a charger to do lipos at the time). And it still was a blast to fly!

I moved to a new job and lost my baseball field that I used to fly my wing in, so I extracted my components and am going to try 3D real soon, as soon as my batts get in (got a Lipo charger for xmas =). So if I ever get back into the wing, I'll definately be looking into a MSW again, and sounds like the lipos and this brushless engine is the way to go! Thanks again for an awesome wing! ...took mucho abuseo and still flew! =)

The weather here in Norway have been pretty bad for quite some time, but the last days have been calm and not to cold. I have therefor got to test the MSW for a couple of packs, and I must say that this is one of the MOST funny wings I have flown ever. I felt confident with the wing right away, so I dialled in less expo, about -50%. With that it was pretty wild but not difficult to fly. I enjoyed the controlresponse very much. I am sure I could have turned it in a matter of a few feet. With the 300DF motor and the mount you made for me, everything was pure joy. It had vertical climb as long as I could see it. I will recommend this wing to everyone who has a little experience in flying, the only thing that irritates me is that I should have bought it earlier. Thank you for a GREAT little wing.
