Prop Size

[thething84]

HI all

well seriously thinking about this airboat now. I have made a design for the base of it etc. will be tunnel hull formation.

Well wot i would like to know is what size prop to use. I have a TRX 15 engine with elctronic start. However it has no flywheel etc.

Also what size fuel tank should i use. as i need to know this to design the enginer supports etc. should i use 4oz or 6oz or 8 oz.

tg84, have a word with the fly boys :) they may be able to help you as you will need an airprop (obviously), or speak to ndflicks or inflex, in the chat room, failing that, marshall cowboy may help
