Sport Original design tow plane: Pegasus

[john Derstine]

Well sad to say my H9 timber 110 finally augured in for the last time.
But out of the ashes most of the gear will party on in my re design of an old original plane I did back in 1997. Digitized and set up for laser cutting of some parts, it's lighter stronger and features a built up wing vs the original sheeted foam. I'm in the process of covering now.
Span 114"
Chord 16"
Area 1790 sq in
Weight 26 pounds all up including onboard electric starter
Engine 120cc
Fuse and wing mostly cut from 3mm luan ply door skins or furniture grade.
Tail is 3/8" balsa stick construction sheeted with 1.5 mm balsa. Spars and stringers are pine .

Looks like a DLE.

Yeah, after honing in on the engine, I could make out DL, so yes, more than likely it's a DLE. Just wondered as I have noticed that a lot of this size plane (sort of Cub) are going to BIG engines, I suppose being a tow plane, it needs to be that size to haul the Glider and get off the ground itself, plus climb well at the same time. Sort of elementary in a way. I have been thinking of going electric on my PC6, approx 110", but maybe better sticking with gas for the tow plane, anyone got thoughts on that ??????? .

Gas engines are cheap and reliable.

I have 2 bigger electric planes the electric set will do the job but, if you need fly at full throttle to pull a glider up quickly to altitude it is going consume a lot of battery you may have to recharge every flight. If add a lot of battery to help flight time you may lose some ability to tow bigger gliders up.
