what extra do you have. I am looking for a good one to build in about 6 months are so.

As for throttle responce, how do you like the 1.60.
I have read some guys here on RCU don't like the 1.60

I have only seen 3 OS 1.60 fly. All three were using a moosecan mufflers, and throttle responce and power seemed real good. All three were hovering where their rudders were below knee high.

If you interested in a moosecan for it. Look up a guy here on RCU called Elvis. He sells them out of his hobby shop. He a great asset to the hobby.
