=tailed (V-rudders) and tailless (thanks 13 deg. wings sweep)4. Removable Tail boom and tail flight surfaces.
Rol Klingberg's 15 meter foot launched wing is still coming in at about 105 lbs...his videos will show you his materials and his construction trades. It's not yet finished so time will tell on final weight and structural adequacy.... empty plane without engine and boom is thus 100-110lbs and is my early goal airframe only weight.
Please make suggestions for additional CF airframes in this weight range or lighter for additional research and comparison... I
I like the redrive over the tail boom structure for the low power drivetrain like this. I think it might reduce redrive weight penalty quite a bit while keeping structurally strong and having good bearing load balance. And two motors should balance forces on the shaft and bearings better than a single belt redrive on a single motor. The biggest disadvantage of this hollow driveshaft idea is the non standard propeller design.Why dual motors to a common shaft?
Strakes on a high wing? Or are you suggesting a "mid high wing" where the head is above the wing in a bubbled area?Consider strakes,
You can make them a wing attachment point,
going from your front bulkhead, to you seatback.
& it's a part that actually makes sense in carbon.
I was going to put some gauges in round lightholes.
Here's a link to one of his material trade videos. from there you can see all the rest. it's a few years worth of sharing design details, structural test articles, load tests, failed processes, fixed processes, materials, flying wing design etc. Plan on losing a few hours!do you have links to Rol Klingberg's videos? build log?
I agree with this line of thinking. I think a great example is the Millennium with a couple of hobby motors.I think part of the current "revolutionary opportunity for new part 103 designs" comes from being able to build light and efficient carbon structures for cheap that thus allow lower power to fly effectively. The lower power required, the less you need to spend on motors and batteries.
