Hmmm....tell me why you're not doing it electric again?



Oh, and is it a kit you started on your own - something you got from someone else or scratch built? Just curious - looks neat.

Ditto. I'd go electric, although the model looks a little heavy in its construction for an electric. I would save the Saito .30 for something a bit more conventional with a lighter wing loading and a secure engine mount to spread the vibration better than through and into the wing. Just my way of thinking.

Without sufficient/proper bracing, that thirty is going to shake things apart easily. Sometimes a .15 two-stroke is a better choice on frail structures with twice as many power pulses of half the magnitude of a four-stroke. Still, I'd probably go electric.

Were I to use a glow engine, I would forego the stock appearance and mount the fuel tank in front of the engine in a nacelle of my own fabrication. Put the tank stopper facing forward and you should have no problems with fuel draw, etc. Just keep the tank centerline even with, or below, the carb spraybar, even if you have to raise the engine's position to do it.

Small models are weight critical. Carrying extra hardware, such as pumps, is best avoided if at all possible.

It is a good looking model. Keep up the good work.
