Hyper ST Pro Brushless clarification....

[shan75]

Awesome build. Was hoping to get some feedback on the saddle config - so thanks!

I was leaning towards 2 x lipo simply due to the longer "fun/run" times for bashing, but even so - would not do it if balance was way out of whack. Based on your commnets - with a bit of tweaking it works well. Appreciate the feedback!

Some good points about ESC placment. I purchased a MM along with a traxxas MM ESC mount. http://www.rcplanet.com/Traxxas_Moun..._p/tra5626.htm Should be well protected I think. Was a suggestion I read somewhere on another forum.

What about rear suspension? Any issues?

The nuts on the rear arm pins can be someone hard to get to. But a set of small/long needle nose pliers is usually all I need. I can grab the nut and unscrew the arm. It doesn't make it the fastest to work on, but it works.

If I went with a set of custom battery trays I'd save some space and it would be easier too. But thats more $$$ than I want to invest. The truck right now is pretty hard to upset side to side. Though I still need to work out the damping and small rhythm sections at speed can upset the back end. I should try filling the rear shocks with 50wt instead of 60wt to see if that helps.

But if you can fit them, it offers balance as good as it can get. If you look at all the purpose designed 1/10th scale electric off roaders they either use a single central battery or saddle packs. Just about anything thats converted from a nitro car uses a single pack for easy of conversion.

One of the things I really don't like is where the motor wires are, but thankfully with as low as they are now the chances of them getting hit hard in a crash are very minimal.

Just take your time, measure out your components and you should be fine. You'll hit some snags with a saddle pack that most people don't see because they didn't go that route. But nothing is insurmountable. My conversion took about 1 month to complete due to waiting for parts, and wanting to do it right. I had questions that needed answering, and some questions only popped up once I had the components in my hands.

This was also my first electric conversion, so going my own way made more questions. But I'm really happy with it. Its supremely fast, and runtimes are good when I want them to be. I think I get about 15-20m on the twin 4S and 3S packs in series. And with the 3S packs in parallel I can be out there for a long while. It tops out about 35mph right now with 3S power. Top speed has never been tested because I don't have a tire that won't fly apart at speed, and the front diff STILL unloads even with 100k center fluid.
