I have one of the oldest UCD .46s in San Antonio. I have worn out standard servos on it, two engines and it has more packing tape than covering. I ended up with Futaba 3010's on ailerons and Rudder and 3004's on the elevators, running a 6 volt battery. They seem to handle the Hyp .50 OS engine just fine.

If you are flying off grass, you may need to replace the landing gear platform soon, as it is notoriously weak. I redid mine with 1/4 AC ply, doubled and pinned, with glass cloth over the top. That setup has lasted nearly four years, through many fun fly's and rough harrier landings.

I just ordered a Giant UCD from Tower this week and am mulling over what engine to put on it. I have four Glow and three gas engines to consider, they are a Moki 2.10, MDS 2.18, ST3250, or STL 50cc Twin (possibly way to heavy) XY .50, STL .50, or DL50. Anyone with any experience would be greatly appreciated to you to share it.

Thanks,
Mike Boyd
