Kraft RC Transmitter Meter Adaptor

thingiverse

Kraft transmitters have aged well and many are being put in service with replacement encoders and 2.4GHz transmit modules. Most Kraft-Hayes plastic parts are very high quality and half of a century mean nothing, however the RF meter is a weak point, It tends to crack and fail electrically. The meter is an odd dimension, however jaymen located a relatively good replacement manufactured in the USSR and marketed on an auction site by a Romanian vendor. All it needed was an adaptor plate, and my version is presented here. Screw holes are set for 2mm, however, I cut down a couple of servo screws to connect the meter to the plate. The adaptor plate is intended to be glued in place inside the transmitter first. OpenScad code is included.
