I have a FAST module in my 3PJs and it works great. I got the unit from A main Hobbies. Ask about there discount codes .I got $12.50 Knocked off the order and free shipping . I also had a custom radio skin put on an oldie but a goody. I can switch back and forth 2.4GHz for racing F.M.for bashing.
Here is where I got the skin from.

My radio was the template for the skin. I sent it in to Darkside and now they have them for the older radios.
