Default Power Pod for BOT

I am planning on building a Bird of Time but in keeping with my first airplane, a Gentle Lady, I want to use a power pod vs a nose mounted motor. I have a hacker A30-12L an a folding prop and want to make a wing saddle power pod, which will be removable to convert the plane back to a pure glider. Any thoughts on how much upthrust I should add to the pod. I was thinking in the area of 5 degrees up and about 2-3 degrees right. Basically, I am copying the design shown in the photo below....

Default RE: Power Pod for BOT

Power Pods are not seen much anymore. Afraid I can't help with this.

With today's light weight motors, it is not hard to do a nose mount AND mount a hook. the motor just about replaces the nose weight so there is not much penalty if any.

If you locate your motor battery over the CG, you can swap it for a receiver pack to drop some weight. But with today's Lipos, that may not even be necessary. My 4 Cell AA packs weigh about 4 ounces. My 3 cell 2450 Lipos weigh 6 ounces. So it doesn't even pay to swap out the motor battery.

Just pull off the blades and add some weight to the nose. Or tape the blades back and remove the power to the motor. Unless you plan to do lawn dart landings, you have a quick conversion to a pure glider.

We have done conversions like this and flown them in sailplane contests off winches. No problem.
