Mayhem ST Brushless Conversion Project

Can anyone make a suggestion for a LVC that supports 5s?

I've looked around, but haven't turned up an external module. If anyone can point me in the direction, that would be appreciated.

Mike had a car LVC in his store. Not sure if he still does or not. You have to pay attention to how the LVC works. If it is a plane LVC, when it kicks in it may just throw you into full reverse.... which would be a bad thing. You need to find one that will put the car controller to neutral position.

If that is the 70A BK controller you might want to think about adding a fan on the heatsink. Its on the small side for 1/8 applications.

J, I checked out the RC-M store this morning but didn't see anything stand out as an option... I'm toying with the idea of replacing the controller with one that has a built in LVC -- Since like you said -- 70 amp is a little on the low side for 1/8th truggy.

With the 9XL I think the maximum current rating is only 74amp continuous... so far with my 12cell NiMh test, I didn't have any issues with the combination, and the less-tall gearing.


With the 5s lipo, I think Its going to heat up a little bit more... Might have to drop by the rat-shack tonite and get a little DC fan to put on there.

Just a quick picture all trimmed up. Still have to form the lipo battery tray, that's on the schedule for this evening!

Finished up the Battery Tray yesterday night... Hopefully I can get it mounted in the ST this evening and maiden the whole setup!

Here's the battery tray.

Nice battery tray, what is it made of?

[hunter306]

Hey Bdebde,

I used aluminum to make the tray, cut it here in the shop then bent it to size. Still need to get it mounted though, maybe tomorrow.

Coated with two coats of Rustoleum Heavy-Duty Primer, and 2 finish Coats of Rustoleum Flat Black High-Temp Coating.

great job on the battery tray

i have been looking for a 5cell lvc for awile too, i havent been able to find anything over 4 cell

[hunter306]

Hey SemiPro, thanks for the compliment. The tray came out much nicer than my first attempt (back when I finished an LST2 conversion!)

--

Here is the setup now, with everything installed and running. I will eventually add a BEC, but for now, the RX pack works excellent, and I can run my BK Warrior setup without the bec enabled.

how much for one of those trays?

[hunter306]

PM Sent, It's hand-made but I tried to give you a reasonable figure to work with.

very impressive build....can i ask where you bought your battery ?thanks...awesome job
