RE: Can a different transmitter be used with the blade CP?
orlbuzz...If you have transmitter that has spectra module or has the capability to change channels. You can dial the frequency the stock rx is using, so you don't have to buy an additional rx. My Hitec Optic 6 has such a module.
BTW: The stock rx in the Blade or HoneyBee are negative shift, thus can only used with Futaba or Hitec transmitters, if you don't one of those brands, you will have to install your rx to make it work.
