I have a Kraft 7cIV transmitter with a ch 40 FM module in it and a Kadet with a hitec receiver on ch 40 in it. You can wiggle anything you want to on the TX and nothing happens to the plane????
This ain't 'sposed to work?

I don't know which "modulation shift" the Kraft uses, but Hitec Rx's are typically negative for use with Futaba/Hitec. However, positive shift (for JR/Airtronics) is available on most of their Rx's too. You need to observe that the Tx and Rx shifts are matched.

Find out which shift the Kraft Tx uses and then go from there.

You know it might be worth a quick email to Tony Stillman at Radio South.

Like Thomas says you most probably have a RX with the wrong modulation shift for the Kraft. What is the model # of the rx.

Also the crystal in the RX must be Hitec and must be a Hitec FM crystal.

That must be it guys 'cause the receiver works fine with a hitec TX.

JR, Airtronics & Kraft are positive shift. Will not work with a negative shift Futaba or HiTec.

Yes I know Airtronics makes a shift selectable transmitter and yes HiTec makes positive shift receivers.

BACK UP HERE the Kraft in neg shift and will work with FUT and Hitec as long as the Hitec is neg not pos. Also if you have one of the switch and click mods in the Kraft TX it does NOT work on CH 4
0. For some reason this was built into the modules . I have these Note TX FM RX has to be FM
