I dont want to bring up a dead thread, so I'll make this one instead.

You could turbocharge one of them with a teeny turbo and maybe make it perform like a china girl until it 'splodes!

I have absolutely no idea what you're asking. Do you want the rotary engines to power the bike or electric motors? Or engines powering generators which in-turn power the motors like a train?

He wants to use two rotary engines in a friction drive setup, a very expensive one though! I think it would be interesting to see what power you could get out of one of the RC engines with a tiny turbo since Mazdas respond to boost very well and you can more than quadruple the power output of a 13B with high boost. Not really worth the effort considering the small percentage that the engine weight is of the total bicycle and rider system, so the power to weight ratio would only be slightly increased by using a rotary, and turbocharging would negate the reliability aspects of the rotary engine. It would be really neat as an engineering exercise though!

I need to go on a diet and training regimen to increase my power to weight ratio by dropping 15-20 pounds! lol

I dont know which electric model engines you are referring to but the brushless motors have mega power per size. There was a 40% contest plane I recall that had a 20hp motor in the planes spinner! They have gotten fairly cheap over the years also. You can run two off one speed control providing it is rated correctly. Range might be an issue.

This might be a "neat engineering exercise", but is it really worth the time and effort? if you could even match the power of a stock china engine I would be surprised. Seems like a whole lot of effort for something that might get you 1 hp if your lucky. Plus think about the load you would be putting on these engines. They just are not made to propel a bike with the weight of a person. they are designed for what they are used for. And they already have friction drive kits for bicycles that produce pretty decent power from what I have read.
