I'm not sure about the size. In terms of logistics and storage size isn't a constraint for me.

2) Gas or Electric would work best for me. I'm not sure about nitro availability in my neck of the woods

3) Choice of materials is open. Fibreglass and aluminum are both options. I'm open to foam, but only if I can take the components and use them for a more robust plane once I'm tired of the trainer. I work in a manufacturing company so having something CNC routed or machined is not out of the question. My boss will give me leeway to use company tools also. I'm an engineer but over the years have become more a business guy so there will be a learning curve.

4) I live in India so I'm pretty sure I won't get **** locally. I'll need to source it from the US/Europe/Far East.


I would advise a .60, balsa trainer. You should be able to find a suitable gas engine in that size range. The PT-60 comes to mind. https://www.towerhobbies.com/cgi-bin...&I=LXJ558&P=SM

The above mentioned Telemaster is another good choice.

I'm not familiar with the smaller gas engines, but I know that there are suitable engines, for either trainer, on the market.
