wastegate- I've heard good things about those motors as well.

im building a stryker and am looking at motors.your mega 2 turn. what prop,batt, and how many amps dose it draw?

sorry for off topic ive been waching this thread for a few years now
looke up that motor, impressive..................

wow! went to the mega site and that is one impressive motor to bad you cant fit 6 cells in a slipso.................

Stroland- My Stryker has a Mega 16/30/2 with a CC125 ESC. I run two Rhino 2250 40C 4S batteries in parallel. This setup with a 7X4 or 7X5 APC sport prop gives me 83AMP WOT at 1300watts. A five cell setup will give me the max for that motor and ESC with speeds in the neighborhood of 140. I haven't gone to 5S yet. Next Spring!

Right now I have been diverted from my Strykers by this interesting little plane. I am hoping to eventually push this plane to it's limits and built it super strong for the later speed runs. I started on a second one from scratch today and nearly have the fuz done. I have five motors to test in it at this time which should keep me buisy!!!

I managed to get 6s-2500 30/40C in my slipso. Given, it had a stretched out, flat belly perfectly shaped for those lipos (IE it didn't totally follow the plans).

I ran it on 6s with an ARC 28-47-2 with a 6x4 prop. Speeds were in the 140-145 range if memory serves. It launched like a log though because the wingloading was 32 oz/ft/ft

Im shocked that poor little wing never snapped!

Man that is a huge battery....wonder if I could get my monster Mega in it? I might super overpower the one I'm building now and see if I can get it into orbit. I've heard some pretty good things about those ARC motors...and the price is right to.

Hi all,
Here is my slipso400 in blue suit. First of all, I was surprised when i saw the AUW : 192 gr with a 2S2000 mah!
motor : emax FC2805 kv 2800
batterie : 2s2000mah (for the first flight)
prop : EMP 5x5
==> ~65 W

The first flight was stressfull, but allmost everthing was right. I needed 10 clics of trim on aileron, altough the lateral balanced was fine... ?
The plane is not speedy on 2s, this afternoon i'll try on 3s with 4.1x4.1 EMP.
The response of elevator and aileron are not "agressive", i think it is because of the "low speed".
the CG was at 25mm af the TE.

next step : 3S!

Clement95- Hey...it's a great day when a maiden flight ends with the plane in one piece ready to fly another day!!!! Well done!

The clicks of aileron are probably because....... I dont see how to make this wing without a tad of warp somewhere which, whether it is balanced or not that warp is going to cause multiple clicks of trim. wastegates wing warped and mine warped some as well. I think Paul's method of using the laminating film in the manner that he applies it might be the key to a no warp wing. Or bagging the wing but I don't know how to do that yet but that is in the near future.
I just noticed that my elevator surface has warped. Looked great when I finished it then 48hours later.....warp! I am going to cut it off and find a piece of plastic today as a matter of fact on my second one the entire tail (stab, fin, elevator, rudder) are going to be plastic.

wastegate · Nov 21, 2009, 11:50 AM

My wing is a lot better now

In the end I did use Solarfilm on my horizontal stab but to get it straight I had to reheat it with a gun and then keep it compressed between two sheets of wood. Straight as can be now.

DownUnderPilot · Nov 21, 2009, 02:25 PM

Well done Clement95!

Bring on 3S

Mine actually maidened with zero trim adjustments required. I could hardly believe it...

Clément95 · Nov 21, 2009, 04:58 PM

thanks!
I already flight it on 3S! this is fast, but i need more

my poor motor+batteries combo! the batteries was too small (3s800mAh), so the amp and volt went down fast...
tomorrow an other try on 3s1600mAh...
this thing is so stressful to fly!
I will read through the thread to find a good cheap combinaison of motor+prop!
Good design!
Clément

Clément95 · Nov 21, 2009, 05:07 PM

zero trim adjustment on a scratch build is very rare, even more on a fast plane, which need to be VERY straight!

Reached into my scrap balsa box a couple of days ago and......out popped another Slipso.....this one will get an inrunner!

Does anyone know the wing and tail incidences? This is my first scratch build and that is the one thing I'm worried about.
