:D My e g,is nearing completion.what kind of performance can i expect from my MEGA 20.30.4 swinging a 12*6 graupner cam folder?on 3s.3300ma.

hello volunteer,thanx for replying.have you seen this sort of setup,or are you just assuming that it will go ballistic.

I'm guessing based upon my setup that puts out 230 watts and delivers great performance. Assuming you meant a Mega 22/30/4 which has a max output of 925 watts then this equals roughly 370 watts/lb. Actually, after looking at the motor specs, you might have a problem getting it to CG and keeping it inside the foam. It's way overkill IMO.

I ran some tests on it today,it draws 25 amps static.the wattmeter showing 260w with a fully charged pack.
The motor is heavy so i had to cut a lot of foam out and sit the pack as far back as it would go.ive used .5 OZ of lead in the tail to achieve 70mm back cg.
whats your powertrain consist of?

I have TP 2100, CC 35 and a Multiplex BL400/6D. With a Graupner CAM 9x5 it pulls 20 A and 236 W. With a Graupner 10x6 it pulls 25.9 A and 302 W. It has an ounce of lead just behind the motor and the battery rides just over the servo on the left side. The AUW is just under 2.5 lbs.

I just hate doing those static tests with that much power.

I have the stock brushless upgrade package BL 400/6D with 27 amp ESC. I am using 2100 mah 2 cell lipos. Static is 26 amps, 190 watts. That's about 75 watts/pound.

Excellent climb. I can't imagine I would need more power than this. Climbs to thermal height in about 15 seconds or less.

my easyg weighs around 1.3 kilos,so im guessing that it should handle fairly strong winds,15-25MPH or so. Is there a point at which the easyg just wont cope with a high windspeed?.Im due to maiden it on thursday.Oh the reason why i ask about windspeed is the fact that the control surfaces on ailerons are flimsy,i may try to put carbon spar inside if it needs stiffening.

The ability to handle wind is far more a function of the pilot than the plane. I have planes that I can fly in 15 mph winds, but if I handed that plane to a new flyer, it would be wrecked in seconds.

Does anyone know how the below setup on the ez glider would work in comparison to the multiplex upgrade kit?
motor- tornado 480 sized brushless

with a 25 amp castle creations ESC

and a thunder power 1320 2 cell lipo

direct drive with 6x3 prop
