Old school Robbe kit that I found 2 years ago.Build as intended except for the use of LiPo. I have only tested it with 2S 2200mA battery, but as the weight is less than half of the intended 7 Cell NiCD battery it performs great. The plan is to get my GPS logger on it. And also to test with 3S mA LiPo. (Motor: Power 600/19) (ESC: Robbe Rokraft 120µ) (8/10)
