Hitec crystals

[bullethead]

Hey , I have a Hitec 3 ch Aggressor with the 03mm Rx, narrow band (sc).

Heres my problem, it works great untill I fire up the engines then it freaks out.

I dont have any room to relocate the rx.

I had this same problem with another truck and it was a bad rx crystal.

Im confused as to what crystals will work with this. (narrow band, single conversion)

Also, what if any other brands are compatible?

Thanks for any/all information,
