Sounds like you are having fun

I would do a test on something that you know works.

And do the steps -
EG -
On you Cessna Plane check thats still working properly with radio.
If so then unplug Cessna motor and plug in micro motor and see if it works then this will give you the answer you are looking for hopefully
motor crook or not.
If Motor is good then you need to find out if its the esc's or Rx , Though you are only using one Rx i think from memory ? so more than likely its the Esc's

Also sometimes dry solder joints can be an issue with bullet connectors.
