Glass vs. build up
The only thing Im planning to put in the ducting is the batt. The length is between 58 and 60" and the WS is probably gonna be around 45". I'm shooting for an AUW of 10-11 lbs. Wings will be sheeted foam. don't know if Ill use mechanical or pnuematic retracts. As far as the engine goes, Im gonna try the prop first. in the design, I'll lay up 2 nose cones. One for the prop engine, and one for the DF conversion. when Im ready to upgrade I should be able to dismantle the prop engine and install the nose cone with the batt tray and reciver tray in it. then Ill pop the hatch and insall the fan and motor. It will probably be alot of work, but Ill only need to lay up one fuse. I may experiment with different size wings also. But, Its in the thought phase now. I am deffinitely gonna start the plug in the next couple of weeks.
BTW the prop engine Im looking at is the G-90, and the DF is OS 91 with Dynamax fan. Dunno which pipe yet or which version of .91 Ill use.
