CG Ultimate bipe engine selection??
 

I reweighed mine - 10.75lbs!!!

That would explain why I have to fly so fast. Still think that the YS 110 would be great for this. May get another one and make sure I build it light!

CG Ultimate bipe engine selection??
 

I used the Saito 150 but could get another Goldberg so I got a DPUltimate. The goldberg suffered an untimely demise last year. I haven't been able to get a CG Ultimate since. I liked the 150, its lighter than the 120 so go for it, You'll like it
