I've seen plans for them but I cant find a simple F-15. Does any one have a link to one, have plans they can share or help me get a few technical pictures I have into a PDF that can be printed out? I want to try some thing but I don't have the plans to build it

Thanks monkey! Teach I saw that but it's more involved then what I want to do. I'm gonna use the minwax trick on this one as well. Nico hobbies sells this kit like the ft speed build kits as well. Only thing that weird is it uses such a high kv motor it's uses a 4" prop. Vids of the plane shows this thing screaming along and flying real well slowly. I don't know if I want to stick with elevons or make it a bank and yank and add ailerons to the elevators

I guess I'm used to slow fly low kv. I impressed the guys at work with the beat to hell F18 last night. Had a good strong wind but it flew. I think the next one might just stay the normal build with out the pod. It makes placing electronics easier and allows for adjusting cg easier I think. My only question is this, and it might just be the full size one but they use a bent cf rod. I don't know if I have that. Could a thicker piece of music wire be used. I have some that I bought by mistake that I could bend like that but don't expect a decent z bend. I also will have to get out the dremel to cut it

They used the CF to save weight. You can use anything, bamboo skewers, metal push rod, whatever will transfer the energy from the servo to the control horn.

I've used the bamboo skewer, with short sections of metal rod. A z bend at one end, and a simple 90 degree at the other. Drill a hole through the skewer and push the 90 degree bend through. Wrap with thread and seal with CA glue.

Saves weight, and is strong.

You missed what I was saying. The designer used a bent length of cf for a stiffener for the plane. I guess I was clear. It goes from one wing to the other in a bent shape

That's the one I'm gonna build. Like I said on nicohobby.com you can build his version of a speed build kit for that and a few others. He even has the power combos for them right on his site. I think the guy who designed these planes should meet up with the ft guys

I know the guy who owns that shop. He came to fly with us at a little Thanksgiving Fly In we had just south of Tallahassee.

You know it was a good time, because the cops showed up.

Well his design is what I used for the F-18. I think I am just going to cut this one out and buy the power combo that they recommend. I might do his modified elevator/aileron.

Another question regarding this plane. Looking at the other parkjet design it has the square tubes for the engine area. Say I was considering changing over the propulsion design and use two edf motors mounted in those pods. First the plans will have to be blown up so that the engine tubes are in scale to the rest of the plane. That's not the problem, that can be blown up and printed out. And the tubes can be made using the experimental airlines tube design and trimmed to fit and look like the engine intakes are supposed to look like after its built and mounted. If they were to be used where would they have to be mounted in the engine pod? Up front, in the back or according to a percentage of the length of the tube? It's really getting me thinking about going this way. The only things I don't know is where the motors get placed and how to wire up the motors. Do I use a esc for each motor and use a "y" adapter into the the receiver for the throttle control? Do I use a "y" again for a larger battery or do I just run two smaller batteries for each esc? I'm probably making this harder then it should be
