I just recently traded a Revo 3.3 for a Summit vxl. I am loving it and glad I did the trade but I have a few questions

1, It came with one Lipo battery and a few of the traxxas nimh batteries. The problem is that it will run fine with the Lipo but as soon as I put the Nimh battery in it the ESC will start flashing Red and it wont work at all. What is causing this?

2, How fast will these things get with a Lipo battery and gearing?

3, What all gearing options are there?

4, This thing is wicked fast with the Lipo but almost impossible to control at speed. Is it just something that I will learn to do or is there a way to make it more controllable?

Thanks and all help will be greatly appreciated.
