RE: Spektrum AR6110 Parkflyer Rx
The 6110 is just a new version of the 6100. It's a little smaller and has the antennas at right angles to each other. Don't expect any more range from a 6110 than the 6100 receivers. It will work fine in park flyers, but if you have a plane that you plan to fly out at extreme distances, get a the AR500 or better full range receiver. I have AR6100's in a pair of Strykers, and I fly them out pretty far, but ParkZone puts the AR500 in the Radian (sailplane) and the new BNF BL Mustangs (39" wingspan park flyer).
