Hello everyone!

I'm working on an battery electric airplane, and I would like to replace that motor by an internal combustion engine (Ref: YS, FZ140).

I was wondering which kind of bulkhead I'd better choose (Material, thickness, ...) considering the fact that an engine will provide more vibrations than a motor (they both have about the same weight).
Moreover, could you suggest me a particular kind of alternator, given the fact that we have some eletric installation on board (wires, servos, ...), and we'll need around 12W of power ?

Here are some overall characteristics of that airplane :
- wingspan : 14.18 ft
- gross weight : 40.1 lb
- Fuselage length : 4.12 ft
- actual motor : 2600W
- Wing Swet = 13.87 ft2
- Swet = 46.69 ft2

Thank you very much for your help !!
