No I have not given up on the Mcpx. I have just put it on hold for now I did have the rft with a DX4 transmitter but I am now waiting delivery of a DX7.
I now own 3 helicopters and plan to progress using the Blade 200 then the mcpx and then the trex. It may take me a while though
I think I will have to strip down the mcpx and give it a good check over. I already have replaced the boom as it was broken for a longer version (I don't know if that will make any difference. I think using a computer Tx will help a lot as I will be able to limit the throws (if that is the right term). There are many upgrade parts available for the mcpx. Are any of these worth while if I need to replace any parts?
