MEGAMax3.7-()Y

These photos illustrate the new MEGAMax3.7-5Y and 3Y motors in Keith Shaw's new 1/4 scale Fokker DVIII and Jack Sowle's 72" Goldberg Sukoij.

Keith Shaw's Fokker DVIII weighs 14Lb., flies with 30 cells turning a 26x14 prop. It will hang on the prop and perform a slow torque roll after many minutes of aerobatics.

Jack Sowle's Sukoij weighs about 13lb., flies with 30 cells turning an 18x8/14 Zinger prop. It will perform most pattern like aerobatics desired with a flight time of 5-6 minutes.

Here's a letter from Jim Collin:

This is just an update on my 1/4 scale Polikarpov I-153 Chaika Russian fighter. I have been flying it now for almost a year and your MegaMax motor has worked flawlessly. I have the MEGAMax3.7-5Y motor in it. I'm running it on 36 NMH batteries with a hand carved 29-22 prop. 99" wing span at 22 pounds.

I have just returned for the I.M.A.A. Festival of Giants at Castle A.F.B. in which I took the plane and had a great time. Thanks again for a great motor, it's nice to be able to go flying and have the reliability of a good motor so all I have to do is just have fun.
