No worries plaecrazy, it is afterall a very impressive build.

Seeing as you've got roughly 60W x 9 of power, you should have enough power to swing that prop. In fact, you may have enough to swing a 16x8 if you were unsatisfied with initial testing. This is all (possibly flawed) calculations on my behalf, assuming a maximum speed of no more than 15,000 loaded rpm per engine. I would definitely start 'small' on this with the 14x6 you mentioned as a precaution.

Also, glow drivers could be as simple as 9 x AA NiMh batteries with glowplug attachments. I know that my C size 1200mAh NiMH cell gives quite adequate power for my glow plugs, and AA's are much easier to obtain. Worth a thought!

Please keep us informed of the ongoing trials.

Cheers - boingk
