i have the nitro planes yak 52 not sure what engine to use any suggestions

os 50 or 0s70 4 stroke

thats what i seen ppl used so far

thanks man what u think about like a saitio 82

I hope to fly one with an old Saito 80 this weekend, if the weather permits. Big if. FWIW, I think it takes an engine of this weight to get the thing to balance without adding weight to the nose.

Regards....

Saito 100 - a lot more fun!
Dead weight is never better than more engine (in the nose).

This video is of my plane, the 2nd day of flying, no fun stuff, just a "walk around the area". But it flies!
