I'm planning on using a very tini-tiny [] SAITO 1.00 in my four star....and to save some weight (to help that engine out [>:]), I'll be putting in some lightning holes in the fuse (or wherever I can ) and cut the first set of bays' off the wing. Not to mention, I won't cover the bird....heck that adds weight, doesn't it?! Will be using micro servos, micro Rx, and a 2 ounce tank....

But seriously, I've played around with a 4*40 and was able to fly it (experimentally of course) with an old OS .15 that I had...off pavement...doubt it would do ANYTHING in grass. Put the .46Fx back on and back to normal.

Let us know how what happens with the .40 or the .32 if you go that low.

PEACE!!!
