If you could tells us what you have on the drawing board might be able help you better.
You guys are great, thanks for the replies.
Milton,
This is the model I have on the drawing board. I already asked about engine choice a while back, and the results were all over the place.
This model will be 80" in span the cord is 10". The nose moment is way out there! So weight is a factor. I have a Webra 1.2 two stroke I thought I'd use. I hate cleaning up the fuel mess, especially on a bipe.
When glo engines are converted to spark, like CH Ignition, do they burn gas or glo fuel. I have no idea about that? Is this an option?
The thin nose would be altered with a gas engine.
