Heads_up,

You'll have a great performer there. I'm very new to 3D'ing, but my little UCD with my OS46FX flies great. No, I don't rocket out of a hover (I'm still working on that ) but I don't go 90 mph either. I used CF rods with Titanium ends, a 1450 nimh 6v pack and the same 12.25x3.75 prop. I've also used the m-k post style control horns. There is zero slop in my linkages.

Let me know how it goes as I'm thinking of upgrading to the 50SX when I feel the need for more power.

2 worries about the guys putting 100s and such in the nose of their planes - you can take it past it's VNE, plus, you're going to vibrate the daylights out of it - already seen several posts about vibration. But again, just my 2 cents - everyone has different flying needs. IMHO if you want to run the 100 or a 91 get the UCD 60...
