my wife Bought a F-20 ducted fan plane at a garage sale with a vilet fan unit and all servos installed it has a lot of hanger damage. I would like to fix this up but i'm not to familiar with this plane or who manufactured it,,i was wondering if anyone out there could help me with any information, it would be very much appreciated

It's a cressline, do a search and you'll find some info on it. I had one, in about the same condition as yours and I was talked out of building it for an easier project. If you decide this is too much work, let me know, I'd always regretted selling mine.

Look at the back of tail and if it looks like it might be warped a bit at the bottom, then it would be a Knights of the Air Kit, From the looks I would guess a Nights kit.

I wouldn't be so sure this is a knights Kit . I have an old Knights T-Shark that I am retrofitting with a Dynamax fan. The both the forward and fan hatch cutouts are slightly different than those shown here. Some pics here....

Yes, It is a Cessline. Mine is still in the works.......

awsome!

nice f-20 cam2:

did you add plug in wings or is a one piece plane ?
can you show me a picture of the internal plane ( engine bay )\

were is the cg in your plane ? control throws ?

alfred

Thanks guys-

The model is does not have plug-in wings, its all one piece. The fuselage is empty sans the fan mounting brackets. Cressline had all servos mounted under the canopy with plastic push rods going to the control surfaces. I chose not to go this route. I also built a splitter plate in the inlets to the face of the fan (dynamax?) for better flow. Control throws and CG are to be per plans.

No CG, OR THROWS are mention in plans or instrucccion, i only have two wings plans , the kit did not came with a fuse plan , so i have not idea were the cg goes.
I UNDERSTAND THIS KIT IS A BYRON COPY, so maybe i can use byron f-20 info ?
please help !
