Thanks for the replies Guys
I can only have a feel of the 3vcs because no one has a Ko Propo.
I've had a go with the 3gr, I found it quite bulky but cant really compare it anything. The thing I didnt like about it was the springs, they were so soft- which I didnt like.
Also, is there a Spektrum Module for the Ko Propo? As I have got quite a Spektrum Rx's from previous Radios. I know there is a Spektrum Module for the 3VCS.
