RE: BLADE MCPX No POWER!!!! NEED HELP !!!!
I doubt its a servo, but could be your radio settings as getting positive pitch requires the movement of all 3 cyclic servos...not just one.
I would check the programming of your radio if you are using a DX6i or higher. If you are using the stock transmitter...I dont know what to tell you as I have never flown my mcpx on the stock DX4e. But maybe a switch is in the wrong position...like Hi-Lo rates?
Someone with more info may chime in to offer more suggestions IF you are using the stock DX4e.
