It probably won't completely overpower him. It will jump back and forth between listening to both of you. This is assuming the ESC does not kick in its failsafe. The closer it is, the more it will listen to him (assuming you two are standing next to eachother).

For example, if the truck is on the edges of his radio range with hte antenna down, and you have the antenna up and try to control it, you will most likely overpower him. But if the truck is rather close, you will split the control more.

One idea is to run rechargables in the transmitter. This will supply 9.6V of power to his. If you then run 10 rechargeables (finding a way to add 2 more cells, possibly by using 2/3AA's like the ones in 18T's and such), and run 12V, which is what the TQ's are supposed to be run at (1.5V alkaline x 8 = 12v), then you will have even more power, especially with the antenna up.

The last option is just to use the failsafe mode of the ESC. When the ESC detects both transmitters, it will just shut down.
