Thanks guys! It's no where near finished yet. So far it's covered with brown and clear ultracoat. No paint yet on mine. That is still to come.

I've got 8 flights on it now. The 8x6sf are definitely more appropriate than the 9x4.7sf with the 950kv motors on 3s. It has nice top speec, penetrate s the wind very nicly, looks fantastic in the air. Great unique park flyer.
The build is fun, it's Not a mountain models or stevens aero fast build, this requires fitting of the sheeting to look good and the beautiful curves take more care when covering than rectangle boxes. It's a great kit to stretch your modeling skills. Just take your time.

Maiden flight

Finally got to maiden my bird.
Flies like a dream but a fast one at that. Had to fly it at just under 1/4 throttle to keep the camera man happy.
Unfortunatey I have an unusal problem to solve as it ended my maiden flight with a crash and minor damage.
I stopped the motors for a glide past for the camera but when I applied power again only one motor started and screwed the bird down. Off with the power and levelled out. Applied power again and again screwed it down. Pulled power back but not enough height and it landed very awkardley. It broke both V-tail fins and a prop, thatís it. Now itís time to sort out why it did it. Both speed controllers are programmed identicle and joined by a Y-lead. The positive wire from 1 x speedie to throttle Y-lead was taken out to allow the BEC to work.
I have to commend Ron on a great design and I look forward to getting my bird back in the air soon.

Well I have a few short flights but they are 100MB each and .mov files. How do I shrink these before I upload them?

The best thing I found was an application called "ffmpeg" with a front end called "avanti". It converted the .mov into .avi (divx) with no apparent loss of quality and about 1/25 the size in a reasonable time.

They are easy to find on the net. I just installed avanti and then found the ffmpeg.exe application and dropped it into the same directory as avanti and it just worked. Run avanti, select the source material, specificy the destination file and format and process.

You can also drop the audio during the conversion if you want to.

It also does lots of video conversions and can produce things other than divx.

Problem solved Hopefully !!!!

May have solved my problem. I didn't calibrate the speed controllers did I . Now both motors start up at exactly the same time. Will try again tomorrow.

Glad to hear you got your dactyl up! Sorry about the crash! I'll have to remember that tidbit on calibrating if I ever change to two ESC's. Thanks for sharing.

Thanks Tim! I'll look into that. It's funny that camera came with software and it won't recognize the movie format that the camera saves the files in. I'm new to digital video.....

There are a few things with two ESCs that are worth considering:

- If possible you want manually calibrated, or fixed endpoint ESCs. Ones with 'auto' calibration can get out of sync.

- You want to use 'soft voltage' limit. You don't want one of the ESCs suddenly stopping with 'low voltage' while the other is wizzing away...

Even so I am careful on the larger 'dactyl to put the power on gently, even with identical motors and identical ESCs the startup can sometimes be different.

Thanks Guys for the info. Put my dactyl back in the air today and it is just the greatsest thing, didn't know that prehistoric birds were fully aerobatic !!!!
I must say that it landed a lot faster than I expected. I too was careful with my throttle control and it paid off. I look forward to plenty more flights to come.

Here's a dumb question. I've never done or used a tape hinge process. Could some one explain the process. Do you do it before the covering is done? Sorry guy's I've only done robarts and ca square hinges.

Another question What is the best way to wire the ESC have 2 or one? I like the idea for one.

Thanks
Marty
