. Thank you very much for your message and your information. Can you tell me if you have made some particular changes with the original plans according to the carbon reinforcement parts for this larger F-14? Also, what servo do you use to moove the wings?

I used the square 3/16" carbon for the wings, and I originally used a 40 ozin MG servo but it would not swing in flight under load. So I put a 85 ozin servo in it still needs to be unloaded for it to swing. So the problem is the big 2" disc that the wing pivots on, giving only about 1" of leverage to push on. There is a modification shown in this forum of using a smaller diameter pivot. If I build another I would use that. It will give greater leverage ( about 2.5" )for the servo to push on. But if I roll knife edge and have the nose up (no rudders) it will swing in flight and looks cool at the same time.

My lightly built version had lots of packing tape for SLICKING UP
ALL of the insides of the wing pivot surfaces. Top and Bottom fuse and wings too

It was 12-14 oz depending on Pak used. N)O BIG Motor and therefore no big ESC either.

It moved the wings fairly well under all but pulling G's loads.

Also agree with the More leverage mods being favorable.

Or put one pivot servo in EACH wing as another option.

I'm still available for cutting these kits.

I just built three of these for me and my wingmen...any tips before maiden? I plan to launch them by holding onto the canopy with wings fully extended out. I have them set up with 20 amp esc's with eflite park 370s and 3s 1300s.

Have fun . That's how I launched mine and it works great . Before I lost it in a lake it was my go to flier for bad weather or just fun . Used to fly it by low and slow above the road and let my son throw rocks at it , great fun for both of us

I know that getting the nose down will help to increase speed but I cant even get enough altitude to get the nose down. I dont really understand what the problem is because thrust is close to 1:1 if I remember correctly. Hmmmmmm, could it possibly just be too tail heavy? If thats the case, I dont have any more room to move batt forward. When I checked cg it seemed to be fine according to the measurements provided in thread. Any suggestions?
Hmm sorry not been around due to ill health but I can only state that motors fans and lipo's is a MUST. . you must use hyperion ys22 6000kv wemotec fans and 3s 4000mah lipo as per my video this set up works a treat for twin ducted fans any thing else don't bother as you can see no power etc but just to prove the point Video attached

power setup/belly landing?

Hey guys,
I just maidened my MDC F-14 today and it was set up with an eflite park 370 motor with a 20 amp esc with a prop size of 7x6 I think. Anyway it seemed really SLOW. I would love to get a good motor esc combo for this bird that can zip around pretty good. Also my buddy maidened his first and we realized that we have to catch ours to make sure we dont bust off the prop on the back. Has anyone found a decent landing gear that these could use or some rendition on the bottom of the plane so that I can belly land it instead of having to catch it every time? Any help is greatly appreciated!

Mine flies sl slowly into any wind that it has never caused any damage from belly landing. Maybe try to slow it to stall speed and flare about 1-1.5 feet off ground then let it plop onto the belly mine does this easily.
