Hello Jai

Ill agree with Stig, and Billybaru, I have had an Avonds, F-15 and the Skymaster F-15, Yellow F-18 and DCU / Jetmart F-14 all had tailerons and they did not have differential.

Sorry about the F-14, I saw the video too bad, I give you credit for going foreward. I had the same thing happen to me with a all balsa F-18 ducted fan many years ago... It just did not get as high.

Just a note the Jetmart f-14 required lots of throw in the elevons when the wings were out. Like 40 degrees or more. In level flight at speed the leading edges were around 1/8!QUOT! down! The fuselage produced so much lift at speed that it kept on pitching the nose up as you reached cruise.

Watching the video it looked like I agree with most of the fliers it looked tail heavy. My friend and my Jetmart F-14's had the CG 1 inch to .5 inch ahead of the wing pivot and even this was nose heavy.

Here are some pictures of My Friends F-14 2 X OS .91 (1999)
