Rock Crawler
Greetings, all.
I finally got around to prepping and installing this beefy, brushless outrunner into a rig that was ready to go trailing. I've already done this work, once before, on my Gelande II chassis, but since that kit is not done, I haven't been able to get it out for extensive testing. However, I liked the motor enough, from the little testing I did, that I decided to get a 2nd one, to put into my SCX10 Jeep Wrangler.
I like brushed motors, but I also tend to go on long hikes in the mountains, and brushless motors are much more efficient, considering battery life. I had dabbled around with brushless outrunners before I got into scale trucks, and when I learned that they were used quite frequently in bygone days of crawling, I thought I'd try it out in one of my scale rigs. I knew they wouldn't be as smooth as a brushed, or sensored brushless motor, but after this weekend's experience, I think they're a reasonable fit for what I do, and where I go with my trucks.
Now, the Turnigy D3542 is a front-mount motor, so the shaft exits the wrong side of the motor for mounting to an rc car/truck. It has to be reversed, using some sort of press. For the motor I put in my Gelande II, I took it to my in-law's and used my father-in-law's drill press. On this one, I used a 20% Harbor Freight coupon and picked up an arbor press, figuring I might eventually perform this operation again, in the future. Other prep work involved replacing the 3.5mm bullet connectors with 4mm bullets, while also splicing in longer leads, to reach the esc. Last, but not least, the 5mm shaft needs to have a flat spot grinded, for a pinion set screw. It's a bit of work, but worth it, in my opinion.
Since others might want to try this in the future, perhaps with this same motor, or another, which might need the shaft reversed, I thought I'd make a quick video of how I did it. (Here's my thread for the scale video I posted, which demos the motor's performance.)
