Im starting to build a 62" Ace and it says to either build the stab with a single top spar for maximum lift or to put spars on the top and bottom for full aerobatics. Iv already flown one with just the top and was wondering if anyone built it with both spars..

I built the big lazy ace (84") and did away with those spars in favor of a traditional flat stab and the plane flies great. It looks better without them too........RS
