"Tech 7 Ampac 780 Power Pack"
This power pack is great. The power range is wonderful and controls my equipment the best. I would recommend this product to anyone who is still on this type of control.

"no resistance in throttle"
Works well as expected. I would have given it 5 stars but I prefer more resistance in throttle for better control.

I am using my new Ampac 780 Tech 7 right now. I can fully confirm that this is a really nice unit and worth the price. I used to have a Duelpack 2-cab AC controller, which was technology out of the 70-80's, and wow things have improved! The Tech 7 really does give you the capability to make your motors crawl at super slow realistic speeds, or race super fast. I also really like the screw panel, were you hook up wires from the track to the controller. It's hard to explain, but I'll try: There's a piece of metal that makes it easier to hook up your wires. Usually, the tightening action of screwing down the screw to make connection with the track wire pushes the wire out from under the screw - but this little piece of metal keeps your wire in place as you tighten.
