RE: GTM Hanriot Build
Hi Mark,
I considered many engines. The RCV is just a little longer, and though the firewall can be positioned where ever you need it, space behind the firewall gets very tight. But you would gain in the available space for a dummy engine. It would be really cool to turn a large prop at a slower RPM, I think it would sound more scale-like. Weight is very much a factor. The Hanriot's nose is so short that you can just(if you are foolish enough!!) hold the top wing in the center without getting your knuckles trimmed by the prop..The final weight of this model is a little over 17 pounds, but the OS has no trouble pulling it around. The RCV is definitely a possibilty! I personally would go electric if I were ever to build another...
