I see tower has parts available for the TT GP07, and for the price of the AP, i might buy two to have spare parts. I read through several threads and they seem to prefer Novels. So, the end question is... Thunder Tiger GP07 from Tower, 061A ASP from Hobby partz or NV Big Mig 074 from nvengnes? Regards Elias R.
In my humble opinion, any of those engines should work. The Norvel .074 would be the most powerful of the three, but even the ASP .061 would work. It is a clone of the Norvel .061. Cloud Ranger's generous 295 sq. in. wing area should be a nice flier. You could even go for an older Enya .09 RC or OS Max .10RC (both non-Schneurles). A .09 or .10 Schneurle of course would be a little hotter, but you could throttle back, fly around at half throttle. Mount servos in tail with short linkages to help with balance, if nose heavy.
Powerwise, I used a Norvel Big Mig .061 CL/FF engine with a lower compression MECOA long plug adapter head and yellow (med. hot) Fireball glow plug, and it hauled a heavy 40" all foam Cessna 180 around with authority. ASP .061 would definitely work.
All three are good engines for your application. Good luck with your build.
