Hi guys,

Might sound stupid, but I simply don't know the answer... so can we connect JR servos on a Futaba receiver?

And what about servo's form factor... do Futaba and JR servos have exactely the same dimensions?

Yes you can connect JR servos to a Futaba receiver. You just have to be careful and make sure your connecting them correct since there is no tab of them to go into the slot in the receiver. If you connect them backwards, they will just not work. Will do no damage.
If you have been using Futaba servos and change to JR. You will have to reverse the travel direction of channel in the transmitter. JR servos operate with an opposite pulse than Futaba.
Yes there is JR and Futaba servos that have the same dimensions. Most standard size servos are the same size with only slight millimeter differences at the most.

With the exception of some old stuff by Airtronics most servos, gyros, and governors are cross compatible.
