Hi all, just trying to get started into this model hobby, and would like some info. Have bought a Warbirds MK9 Spitfire, going for a four stroke engine .61 cc from Hobbyking It has servo less undercarriage. I have a DX6i transmitter, what sort of servos would I need. looking forward to the build but not sure about the electronic set -up..Any help would be appreciated. Thanks.
