Since I focus on odd speed runs and fun builds, I've been getting excited with this warm weather finally getting here. That being said, here are some pics of my Big Brushed Motor TT-02. I finally had time to trim and mount the new 795 motor in place of the 775 motor I was running. I will have a bit more torque now as well 1000kv instead of about 830kv. There are also spools in the diffs both front and rear, now. I've managed a 52mph with 6s so far. It has been an interesting build. If it can get past 60mph I'll call it a success and probably bring it out to bash every once in a while. It sounds so smooth with the big motor directly connected to the diffs.
775 vs 795 Before trimming the you could see that not only was the 795 motor a tad longer, but so was the shaft. It wouldn't fit the couplings I've been using this way.
After some semi-careful trimming, the bigger motor fits!
This is what it looks like ready to drive. This set-up got me to 52mph on 6s. I tried these larger tires with the first motor in an attempt to get more speed out of it. There wasn't quite enough torque to maximize my speed like this. That was part of the reason for the larger motor. I'll be trying different tires to find the balance I need as I get it back on the road.
Testing the first set-up. It was easy to see that even with puttied diffs each wheel was gonna spin at different speeds. These tires were all taped and glued. I imagine they'll need retaping again before being used for any high speeds. I be trying foams on the next runs.
Wish me luck!
