I designed this in 2009, and just re-made one in 9mm depron for fun, flies very nicely.

If I was the convert the radio control modeler black bird to rocket power do you think a G80 would provide enough thrust for a decent lift off? Weighs 2 pounds 10 ounces no rc gear yet. 38 inch wide wing by 50 inches long. https://outerzone.co.uk/plan_details.asp?ID=6111

It all depends, you have to consider the before and after weight of the rocket motor, look at the CG change and decide if the shift is manageable with elevator up trim for glide. You also have to consider your boost speed, faster is not better, you have less time to react. For comparison, my YF-12/SR-71 kit is 39" long with 21" wingspan, and uses a 24mm motor with 12.5 oz rtf weight with motor and 1 ounce of propellent, which gives a 3/4" cg shift which is managable with my larger elevons and a glide weight of 11.5 ounces. The G-80 has about 2.25 oz propellent and weighs about 4.5 ounces, so with radio/motor you are looking at around 3.25 pounds plus whatever nose weight is needed. The G-80 will lift that ok, not to great height maybe, but is a 2" CG shift ok in that length with the controls you have, and will it glide ok at a 3# + glide weight given the area, you'll have to decide. When I use that size motor it was in a 72" long X-15 cruciform profile that weighed only 38 ounces ready to fly but had a TON of surface area, probably twice what you will have and at a pound less glide weight.

Well, I have finally got to go out and get a few RG flights in.
I flew my Estes Centurion and Hobby Labs SR-71 a few weeks back and managed to break loose to spend 2 Ĺ days at LDRS where I flew the ME-163, thatís always fun.

Excellent gliders, I'm jealous of the large Komet. Did you buy that from an RCG classified ad?

OOP RC kit.
It was designed for a 60 sized glow motor up front.
I modified it to take a rocket motor and strengthened the wing spar.
The canopy was cracked so I had to make a mold to produce a new one.

The kit is still available, at a higher price than back when it was new and available at Fly Boy Hobbies and later at Hobby King.
