RE: Thorpe F-20 build
The reason for the Wren 75 is that I have one already that I can put in it. Why do you guys think it is too much power? It easily fits in the fuse and takes much less space than the Tubax I fan unit and OS 46. Thrust is only about 15 or so pounds. I estimate this model will end up weighing about 10-12 lbs dry with another pound or two for fuel. Doesn't seem overpowered to me. I flew a 17 lbs thrust P70 in a Yellow Starfire that weighed 14 1/2 lbs dry and it flew great. I should have never sold it.
How fast is this F-20 at top speed? 150 mph? 180 mph? 200 mph? I would like it to go at least 175 mph.
I am currently flying a 1/8 scale Tam F-16 with the Wren 75 and am use to landing slow and nose high. It is underpowered by the way. Does the F-20 land the same as the F-16? The F-16 will not snap. I don't care how slow you fly. What about the F-20? What speed does it land at? My F-16 lands at about 25-30 mph. Top speed is about 170 mph on a calm, cool day.
I appreciate the input guys.
