Successful buggy conversion!

[Rcaddict]

GlassDoctor is da man. After reading some of his posts about his brushless 1/8 scale vehicles, I was inspired to convert my MBX-5 to brushless. I read everything I could on RcMonster and went with the setup recommended by GlassDoctor. Let me tell you, that setup was dead on. The buggy performed above and beyond my expectations and I couldn't be happier with it. I went with a Neu 1512/2.5d motor, Mamba Max ESC, UBEC, dual 2s6000 MaxAmps Lipos in series and a 14/46 gear ratio. Mike made up a custom motor/diff mount that was a work of art and allowed me to run the Kyosho 46 tooth spur. Thanks Mike, GlassDoctor and everyone else on RcMonster that helped me out.

Impressive!!!!
I want a 1/8 buggy, too.

what thickness aluminum are you using for that mount

[coolhandcountry]

That is nice.
It looks about 8mm or 5/16 thick for motor mount.
How the test run go?

Welcome to the forum bmmermazda.

It's 8mm aluminum.

The test run was incredible. I wanted the buggy strictly for racing and the 14/46 ratio was perfect. I can't imagine what this thing will do a 16 tooth pinion. After a 15-20 minute run the motor and ESC were at about 160*. The ESC was very smooth. I had a little cogging from a standstill, but I found that if I eased into the throttle the cogging wasn't a problem. Braking was very smooth too with the Mamba Max. I was a little concerned with the batteries being so far rearward, but after a little chassis tuning that car felt great.

Cool.... glad you like the setup. It's worked awesome for me...

I think it's a killler racer's setup. The 14/46 is a nice starting point.. that's what I was running. But if you really want to see some jaws drop, slap in a 16 or 18T pinion. :) :) It really comes to life then hee hee

That motor mount looks serious! Pretty nice...


Now we just need to get CC to fix the bit of cogging off the line and it's all good.

Wow I am thoroughly impressed. That thing looks VERY good...almost factory...

How hot did your MaxAmps batts get on your test run?

[Rcaddict]

I forgot to check the battery temps. I'll run it again Friday and check that out.

that thing is nice! hope you're racing next sat. i can't wait to see the look on everyones faces when the race is over. i'm finally going to race my g2r, so we'll just have a brushless party! lol!!!!

...i thought that if you put your throttle EPA into a negative number on your propo that it would cure, or at least improve the cogging off the line...It wont BURST off the line but its better than sitting there choking on itself...

...This MIGHT be a silly question but the in the closeup of the motor pic it looks like the ESC doesnt have a case on? You took it off? the thought had crossed my mind but the pros and cons of doing this? I was worried about getting goo in it...Thats not an issue?

Your buggy looks AWSOME :027: . How did you get the kyosho 46t plastic spur to fit ?. I was told it would not fit the mugen center diff.

You're right, the Mugen diff won't work with the Kyosho spur.
Mike made a custom diff mount that uses the Hot Bodies center diff.
It works great and mounts in the original diff mounting holes, so the chassis didn't need to be altered at all.

How much does the whole setup weight ?

Thx !

Looks great !

PS, the only thing I would alter in that setup is the motor mounted high like that... it really puts the center of gravity much higher. The motor is about a pound, much heavier than the head on a nitro. I think you will find the buggy leans a lot in corner and if it doesnt, you're losing on traction by compensating with heavier springs.
