I asked about if the OS FL-70 is great choice for a 46 UCD and they told me to install an even bigger engine, while the manual only reccomends for the 46 4-stroke engines in the range of 51-70 (something like that). That's why i chosen a 70, because is the biggest i can install. With a bigger engine, i think it will be hurt to do aerobatics. What about that?
There is a 3d flying forum of RCU where you might get a good answer.

The u-can-do, and its set up, is definitely above the level of the beginner forum.
I already did it. Is just that you began the 4-stroke converstaion, so i given a shot, to see what i would fish

The answers are the same as the 3D's forum, of course i had one PM here and that helps me a lot, thanks
