My first engine on the Stearman was an MDS .48 which was good but I then installed a Clarence Lee modified K&B .61 and it is just about perfect.

Initally I was disappointed in the Stearman's roll rate so I installed a matching set of ailerons on the upper wing.

This makes a good flying airplane into an awesome flying one.

I have as much rudder - elevator and aileron throw as I can get and then use dual rates and expo to tone it down a bit.

All of my strut screws were replaced with allen nut and bolts as the upper wing really takes a beating under extreme 3-D flying.

Pick up a copy of the book "All About Bipes" by Harry Higley and follow the instructions on how to properly set up and align a bipe.

I use 2 Great Pains Laser incidence meters on mine.

Mine is just about the best flying bipe I have owned in over 30 years of RCing. It is very fast, tracks like a pattern bird but will do Harriers and hover almost on par with one of my Sig SE's.
