[NSRCA-discussion] Kraft info

[Bob Richards]

Jerry,
 
Channel 04? That is a ham frequency, is it not? If so, then you will need more than a crystal change to put it in the 72MHz band.
 
The 4 pin connectors are Multicons. As long as the servos only have 3 wires, then you could probably get them to work with modern stuff (just make sure the logic level is compatible). I agree, is probably better to splice in new connectors. And servos that old, I would at least send them in for service. The lubricant in the feedback pots could have dried out, and the wiring could have become brittle. Personally, I would lean towards installing new servos, at least on elevator and ailerons.
 
(And, yes, I am old enough to remember 4 wire servos. But I am NOT as old as RVP). :-)
 
Bob R.

I bought a Tiger Tail III many years ago that was built way back, and has nose and wing retracts. It has Kraft servos and Rx, and  a Signature  Series  Kraft Transmitter with it on CH 04, stickered in 1993.
Radio was built as a Custom model in March, 1978
I am  replacing the Rx and Tx batteries.
Several questions I need some help on.
1. Where can I find some 4 pin connectors to make up adapters if I need to use a different TX and RX--my old Ham license is long gone..
2. Where can I find some kind of a Manual on the Radio.This plane has retracts on the nose gear and wing gear, 2 servos on the throttle, normal Ail/Rudder/Elev. setup for the time built. 
3. Where can I find xtals to convert to a regular channel.
Engine is an OPS 60 almost new-very good shape-and I am cleaning it up to use.
Plane was flown several times --too fast for the builder, so it went in the ceiling in the basement until I found it.
My intent was to kit the version (III) and I built a plug for the fuse and canopy, and layed out the planforms and airfoils. Then building and kitting the 2 meter planes got priority. 
Fixing it up for Ballistic Pattern--
Thanks for any info--
