Brushless help
 

Would like to purchase a brushless system within the next few months. I would just like to get some feedback since brushless is new to me. Any suggestions or links that would help explain the in and outs would be appreciated.

welcome to the forums! as far as learning brushless, just read a few posts on any of these forums. rc-monster forums are the most informative as far as brushless goes!

First off, what kind of car or truck is it?

Kind of truck. What upgrades if any you have or plan to do? The money you plan to put out for a brushless system. The size tire you have. I know it is a few question but they need to know items. What speed and power are you going to try for.

Welcome to the forums Coolbeenes, and i know it sounds like a lot of info to post to get an answer - but the great people here at RC-Monster want you to get the right equipment for what your going to be running.... Good luck - and once again, welcome...

Thanks for making feel so welcomed....I currently own a E-Maxx. I was really into tow tears ago until I got a new job and had to move!! It has been in suspended animation for two years!! The last mag I had was taking about the new Matched 3300's. Man, it funny how much can happen in two years. I just recently got my truck back out and it fired back up with no problem. Brushless systems were just really beginning to become popular when I pack my truck away. Now it seems like wveryone got them!! Mt truck is modified somewhat. Below is a list of the upgrades I have done. Keep in mind this is from two years ago.

Robinson slipper kit
Locked into second gear all first gears removed
Gearing servo removed
Futaba FM radio
Hitec 645 steeering servo
Ti hinges, turbuckles and pillowballs
All traxxas aftermarket internal componets
Pro-line suspension kit (I bought my E-maxx the first year it was out)
Pro-line velocity dish rims and Road rage tires
Traxxas big bore shocks with Trinity springs
Matched Team Orion 3000's (I just picked up some matched 3800 Ib's)
RPM bumpers, skids, bulks
Replaced all of the bushings with bearings


Now I under stand I will probably have to upgrade the idler gears and the drive shafts to run brushless....Any suggestions on other upgrades?

cvds are a must because the sliders wont last long. Also upgraded diffs would be a good investment.

You had a hopped up emaxx two years ago. The upgraded internals has me worried. If you got the aluminum out put shaft and input shaft. They won't hold up well under alot of power. I have been thru them. If you go cvds the ue are the best. The robinson will hold up to some force. I think the strobe is alittle better for it has the mod 1 gears. I take it you still running the stock tub chassis. How many cells are plan on runng 12 or 14? If you stick with the stock diffs the 10 L may be a good choice for it won't be to hard on the driveline. I didn't catch tire size. If big tires it will be hard on drive line anyway. I love them though myself. If you want more power you can choose a 8xl or even 7xl depending on the run time you want.

I guess I am looking for something that will give me a balance of a significant speed increase without sacrificing the runtime. Do all brushless systems run on two series of batts at the same time? I just got 14 matched 3800 Ib's that I need to put together. And yes I am using the stock chassis.

Not necessarily. People generally shoot for higher voltage so a motor with more turns can be used for better runtimes yet keep the power. If you use only 7.2v, you'll need a fast motor to get the speed you want. That kind of motor will have a lower turn count, but will require high currents. Runtime will suffer and you'll need strong batteries to deliver the current. If you use 14 cells (16.8v), you can choose a motor that has a lower kv rating and runtime will be better. Some people even go higher voltage for more speed if you want to get crazy (over 40mph). Just keep the max total motor rpm around 35,000-40,000 rpm for whatever turn motor you select.
