Well maybe 20 mm would be fine. Got my titanium M4x10 button heads today. .63 g each ;(
Looking at Jr 188 servo location. What to do? With screw tabs on they barely fit crosswise. They Seem so tall?

Random build pics. While I wait for my China battery to arrive or make a mockup and decide best servo layout and cg location. I have a couple possible servo trays curing. 1 is two layers 1/16" birch on bias with some carboweave in the middle. Another of 1/16" ply with carboweave top and bottom.

Well my Stella Build is complete. 126 g on a +/- 1 g scale without battery. taping a nickle 5.02g on the nose puts the CG at 65 and 132g.
I hope my battery is lighter than 5 g. I might need to shorten the servo leads if I need a CG closer to 70.

IT was a fun build and I desire my china 200 mHr battery to arrive soon.
How much doe they weight exactly? hope like 4.5 g ?

Nick tells me some Guys in China have built them under 120 g? I do build tough. But I am learning how to keep things light.

Try the stella version1 today before the sunset, I really like this little monster, not a full power launch, easily reach 50 and near 2min in calm air.

This is a 4 servo rudder plane for a customer with 4*65k servo(rich man~), comes out with heavy nose that I need 1.5g tails weight(never has tails weight before...) it runs really really fast. I added lots of camber, near 5-7mm to make it float slowly, as my previous beta MiniDF is modify all-moving stab, it seems this one is much stable, 44cm LE-LE, with CG 65mm. I think I would like it on 68-70mm, but I don't have enough time to trim it more backward. fun fly plane and I still managed to find some smooth thermals beside the trees. Wonderful day with the Stella!
