Based on the size of the prop that was on the ill fated Sukhoi ARF, it was probably a 40 or 50CC engine. Creek recommends a 1.20, most of use a 1.60 glow or 1.80 (30cc) gasser and even that is significantly overpowered. If you use a 40 or 50CC that is just insanely overpowered.

Pinning the firewall and glassing it still won't cover the fact that the plane was not designed for that kind of power, yet we blame "the crappy ARF quality".

I have a Kangke CAP 120 (ARF) with an RCS 1.80 (30cc) it rips the sky, it is very well built (it came with a pinned firewall and glassed tri-stock behind the firewall) but would I expect it to stay together with a DA 50 on the nose... HELL NO!!

Let's use a little common sense guys. If you want to fly a DA, ZDZ, etc.. .buy a plane that is designed to handle it... i.e. Aeroworks, Carden, CA Models, Chip Hydes, etc. Of course you will pay for it.

Don't get cheap on the plane and expect a plane designed for glow to support 3 times the horsepower and stay together!! ARFs serve their purpose, but don't expect the world of them.....

If you want a plane that stays together, spend the money on a strong arf, or better yet, build it yourself!!
