Both are 72mhz AM narrow band and does not look like there is any connections on the back for a trainner cord. I got the conquest from the swapmeet, an old lady had a box of tv remotes and this one was also in it. She wanted 8 bucks for it, but sold it to me for 4$. I got the attack 4 with the matching rx, rx pack and tx pack, with a complete rc10 vintage graphite car, esc, batteries, motor, quick charger, and a lot of misc stuff all for 30$.

I found someone on craigslist that wanted one, sold him the conquest tx alone, he bought it for 15$.

Thanks for all the opinions.
