Great looking build!

What's the weight so far?

A few bits to do but weighs 500g at the moment with battery.
Think its going to end up about 530-540g but will let you know later.

Had my first flight yesterday evening in calm warm conditions.

First launch the model nose dived and hit the ground reasonably hard.
I trimmed the nose up and re launched which was a little better.
After a few flights I ended up with the ailerons trimmed up about 6mm each side to
get it to fly level. I played with the c of g which made little difference.

Is it correct to end up with this amount of trim?

I also have a question re the aileron setup.

Normally you have more up than down aileron movement but it appears the opposite
on the Dart. Is there a reason for this?
Also in thermal mode it says to have up aileron. I fly dlg's and gliders and this is opposite to
that. Is it flying wing thing?

I will hopefully post a video showing the first flights later.

Regards Martin.

Yeah. 6mm is approx. what I have on mine.................It's a lot of reflex but all flying wings have some amount of reflex.

The ailerons on high performance sailplanes typically have some aileron differential. (i.e. more up than down) to facilitate turns but not flying wings.

I have a thread for my RES-Dart build on the thermal forum that includes first flights and some thoughts on this design.

Hi Steve
Thanks for your reply. I thought I had done something wrong with the wing build
but you have put my mind at ease after reading your thread. I hope to fly it on Wednesday
when the wind drops a little. I'll let you know how I get on. Both fuselages are ready so
will try out the power version as well. I used the ply fuselage for the powered version and made a balsa one for the glider. Im probably going to end up making another couple of fuselages to get better c of g's so avoiding adding weight.

Using the plywood fuse for a powered version was exactly what I planned on doing!

What was your final RTF weight for the un-powered version? Mine flew at 18.45 oz / 523 g.

Steve on some very dodgy kitchen scales 540g without a battery.

That's pretty light. I think I saw a build log where the final RTF weight for a stock RES-Dart was 22oz.

I'm convinced the RES-Dart can be built at approx. 16 oz.

Mine flies so well at 18.5 oz / 525 g once it's off the hi-start that I'm tempted to sell the one I have and build another kit. With another 40 ft of launch height and this thing could be a consistent contest winner.

Be interested to see your build Steve, hopefully flying mine tomorrow.
To save weight I think you need a short nose fuselage for a powered version as I have
a ton of ballast with the stock ply fuselage and for a glider version a longer nose which in my case would reduce the battery weight needed to get the c of g.

Mine came today. Absolutely no shipping damage to the box. Will open it tomorrow.

Bob good luck with your build. If you need any help let me know.
Handy pictures in this document which I found very useful.
