Sorry Bob, didn't read post 25 complete, i instantly scrolled down after having read this:

"BUT, it DOES have a mechanical servo to control the elevons, yes, it has operating, and controlable elevons, and a close look at the bottom view will disclose all of my secrets."

Should have read complete.
Please report yr. progress. That idea is brilliant.

Hi Stephan...

Again, thanks for the kind words, and encouragement !

I have now completed (5 minutes ago) the control mod, useing thread instead of the carbon pushrods, and get almost 6 times the control movement.

I have also moved the cg back a whole bunch, and am waiting for the afternoon winds to die down here in LA.

I'll see if I can figure out how to upload a video of the elevons being moved by the differential thrust.

I can't wait for this evening...

Hi Folks...

This is my first attempt at uploading a video... The file I uploaded was in MPEG4, I hope that that is compatable with this system, and the potential downloaders.

I have a file conversion program, and should be able to translate it into something that will work (if this does not). What is the best and most convieniant file format for video on these threads...???

I'll try to post it now, and if it comes across, I'll post some conversation to go with it.

Does THIS work... ??

It is in the Gallery as AA-Kat, if the above does not work.

place the movie online - like in your ISP web space, then put a link to it here

eg: http://mywebspace.myisp.com/themovie.mpg

and it will be able to get downloaded by us.

Hi Folks...

I was wondering why the traffic died on this thread, then I noticed that I had added my video as an "edit", and not as a new reply, and that does not send out a notice of activity on this thread... dah... Sorry about that.

The video is posted on message #33 above, and is of a demonstration of the differential thrust motors powering/controlling the elevons.

It is now done with thread (a "pull-pull" system), and is VERY free in it's movements, and the response time from stick movement to elevon movement is pretty good (as visable in the video).

A "front" is coming through the LA area, and the wind was too high to try a flight this morning, but if it dies down, I'll give it a toss, and report back the results, whether good or bad...

It was too late and I had already done it... and yes it failed... only could manage a little above level flight at WOT. So back to "up thrust", which we can now state is a must.

I have an indoors night here too - so if a certain flying buddy is there I will see if he can grab some flight footage of it.

Well done selfo
A suggestion would be to get the angle of attack up higher and it will climb better during straight runs and won't lose so much height each turn

das the end of the battery it climbs out at 1/2 thr. on up at about
15-20 degrees with no wash out/ramping just goes up or goes level or goes down. I dare say it flies perfect. Ill get more vids next time as Im going smaller and making a f15 muhahhahha
