WhenI was assembling my Reaction X, I used Todd's Pro-link retracts and sent them to Down and Locked for conversion. I use redundant A123 6.6 volt Rx packs and power the retracts with them as well. After 4 flights I still have over 85% capacity left in the batteries. The wheels are Intairco and they are quite heavy. Retract or extend is less than 5 seconds. No way are they 10 seconds! It's a great feeling to know that when you flip the switch the wheels are coming down.

The plane weighs 33.5 lbs all fueled up with a Gallon of Kerosene.
