MQ VR3
Here is my recent letter to DTX.
4 backs and the POS was TOAST, the tab with the comm attached melted off.
I ran your VR3 motor with an xrs sport reversible ESC and an elite 1500mah 6 cell pack and it lasted no more than 4 packs before the bronze tab that the comm sits on melted. I even had one of your Duratrax aluminum heat sinks on it since I thought it might run a little hotter. This is in a Mini Quake truck with 100% stock gearing and the only other mod is the duratrax cvd's. I was EXTREMELY dissapointed in this motor as I only got to run it 2 days before it was toast. I can understand that my input pinion for the diff broke and the bevel gears for the front diff, these things happen. But for a motor to burn up after around an hour of run time is just absolutely abysmal.

RE: MQ VR3
Just to follow up, Duratrax support is pretty good.
It was a day or 2 in between replies but to be honest I bet they get swamped lol

RE: MQ VR3
Me too. I think there were 2 potential reasons for failure. One being that I did not use a contact grease under the heat sink, and two being that I think full throttle off the line may have ran too much voltage without the motor actually moving and may have damaged it. With this second motor, I am going to run no heat sink, and keep the throttle low until the truck is moving and see if I get more life out of it.

RE: MQ VR3
but how much can you REALLY expect out of a 15.00 motor? though for the price the vr3 has held up great in my detta and is plenty fast. But it just doesnt compare to my reedy mini mod or lrp fushion.

RE: MQ VR3
Well, I see people running them in the detta with no issues, and duratrax lists it as a hop up for the quake so I guess I expected it to last a heck of a lot longer than it did.....
The fact that it works great in the detta has me confused...
