MSRX won't gain altitude
I can slide across the floor for several minutes but it doesn't have enough something to get very far off the ground.
I have installed MCP landing gear and have been using EFLB2001S25 200mAh 1S 3.7V 25C batteries for over a month. Have several batteries with at least 4.10 volts. |

I would check these things:
- the gear D shaped hole is aligned with the D shape of the shaft - the gear is all the way on the shaft (hold the head down and push up on the gear. It's pretty durable so don't be afraid to use some force). Even if it appears flush with the frame, the shaft could be riding up a bit high in the frame. - find a YouTube or finless Bob video on how to verify zero pitch on blades and the extent of pitch change as you move throttle stick - verify the blades are not on backwards - are you using a computer radio, the dx4, or some other ultra micro "pack-in" radio? I wonder if the receiver could get confused about what radio you are using and assume zero pitch instead of faking a pitch channel like I believe it dies if controlled by the dx4.

The msrx is fixed pitch, he probably needs a new motor.

Motor would be my guess as well. Mine did the same thing, new motor and it is flying again.
