Post by: ffinybryn on August 11, 2012, 09:40:29 PM
It won't win any air races, but here's a mock up of my new Skywalker...

Not sure how long it will stay like this!  Am off for 2 weeks now so hoping to get some flying in if the weather stays fine.

Looking good :) Just don't have any "Unscheduled landings"...

First maiden didn't go so well...  Seriously underestimated COG.

After recent problems with trying to get my Raptor off the ground, I probably set the COG too far back and it immediately stalled - luckily into brambles.  No damage done.

Have now replaced 2200mah with 5000mah as far forward as possible - giving COG about 20mm behind servo line.  Weighs in at 1.950Kg.

Waiting for next non-windy day...

Addendum:

Had another maiden last night.  Didn't go "backwards" like before, but struggled to turn.  Quickly got it down into the long grass and cranked up the ailerons to 125%.

The next flight was a success.  After some rapid trimming, it flew straight and level.  Even managed a perfect glide landing.  After a few more LOS flights it'll be FPV ready...

Good stuff :) Your CG wants to be 20 -30mm back from servo slot 30 maximum. I found the same with mine, the ailerons are really naff and need a bucket load of throw just to have "some" effect on the planes flight path :)

I agree with Coyote on the CofG and ailerons. The Skywalker needs some rudder to turn nicely, don't mix it in just use your thumbs for a nice coordinated turn, have fun.
