Ok so I have access to a DA-85 and I am building my second EF 50CC Extra 300 is a 85 in this airframe to rediculious ?
The way I figure thrust to weight will be 3:1.

I was maybe going to use a 3 blade 24 x 10 prop to tame the torque.
Basically I need input this is getting into wing loading and airframe stress, so how bout it ? Anyone done it in a 18 - 19 lbs aircraft, how'd it work out still in 1 piece ?
