Default Sig Tri-Star

I am building a Sig Tri-Star and want to make it electric. The plans call for either a .15 sized glow or an .05 brushed. I am going to use brushless and don't know what set-up to go with. I am building it stronger with additional spars in the wing and other strength additions where I thought it needed so I can try and get some decent speeds out of it. What set-ups would you recommend. I plan on running a 3s 2200 Mah battery.

Using the standard rule of thumb.. watts = cubic inches x 2000... that suggests ~300W... of course you'll probably be able to use a larger diameter prop than you could have run on the .15.

That's about right for an 05 brushed electric too... they could cope with 25A-30A on 10-cells.

How did the Tri-Star turn out? I have one, minus the wing. I am in the process of getting the plans
so I can send them to Flying Foam and have foam cores made.

Mine didn't do so well. Balance was off and crash was bad. Still have the plans if you want them.

Sure, that would be great. How about any parts? Engine cowl? Iimagine that it would be
difficult to determine the CG of a plane with a wept wing like the Tri-Star.
