I am building a 30% Ultimate - the all up weight (dry) allowing 5 - 7 lbs for the motor will be about 18 - 20lbs. I aprticularly like Zenoah engines but cant decide between the simple and cheap sigle cylsiner 62 and the sexy more powerful but much heavier and more expensive 80 twin.

Any suggestions??? I want lively and unlimted vertical performance - it should pullout of a torque roll like its on a bungee but it doesnt have to only ever fly at less than 1/2 throttle!!!

Come on guys - help me out here???

Cheers

A Zenoah G-62 will not give "unlimited" vertical on a 20# bipe. Go with the 80.

Hi David,
Since ZDZ has come out with a couple revisions of their 80cc, it might be a good time to get a good deal on the older model. This would more then meet your weight and power requirements.
