I've been using this ESC in my TT01 for playing with my fellas for many years with lots of different receivers (hitec, acoms, futaba, JR) and no problema at all.... Actually I doubt output voltage is 7.2v.... I thought it was 4.8v.... I think most receivers will handle it, you should worry about your servos.... that's why some receivers have BEC circuits... now that I'm recalling, I think all those receivers I had used with this esc have internal BEC circuits... that's why it has a BEC connector and not an standart futaba connector....

It's Tamiya's most generic low-cost ESC, made to work with anything.. standard BEC voltage is at most 6.0V for any speed control, some may be 4.8, but never 7.2V..

Some higher-end speedos will have 7.2V for the FET line of your servo for the extra speed, but certainly not this one. I've seen so many people use these since they came with their minis, with every make and model of receiver. I'm sure Tower just filled in that number. It'll be safe for your equipment.

Thanks i was worried that i might break it...Is it normal for the receiver to get warm???When i tried it last night it was warm.....

man, you're scaring me.... i've never had any receiver getting hot.... don't you have any inexpensive tester at hand? check output voltage with the battery connected and switch to on... just to be sure, test it by yourself....
