Hi folks,

Posted this in the MMP thread but it's pretty empty in there. Since this about putting lots of power in a B4.1, I thought I'd check with the experts!

Hope I can get some initial setup advice here. I'm about to install a MMP and 4600kV 1406 Castle motor in my B4.1. I was going to start with a 19/87 pinion/spur. Running on a outdoor hard pack clay track that gets a bit black groove when moist, but dries out often too, making it kind of loose. The locals here in AZ pretty much run Double Dees on the back. It's about a 30 second track, great times in the 25s, with a lot of jumps and turns, and really only 1 straight that's not long enough for full throttle for more than a second or so.


I know it's a lot of motor, but a wanted something to give good punch and torque for digging out of the corners and, well, be a lot of fun! So please don't just rain on my parade, I know I'm going to have to turn it down.


What I'm looking for are some tips for setting the throttle and brake curves, torque, punch settings - whatever else might be a smart way to properly harness the power of this setup... thanks in advance!


Any more info needed, just let me know..

thanks,D
2 lines short of full timing on the motor. 90% boost on the esc. 24/78. Runs awesome! Ran that the the jconcepts supercup in ocala, fl last weekend. SuperFastt!

I had an MMP in my B4.1 with the 5700KV motor for a while. Insane power. Too much, kind of like you figured. On our tight indoor track here in Minnesota, I ran gearing similar to yours with the overall power set down to 75%. Did some fartin' around with Punch Control and attempted to run the Torque control routine on it. I'm not a great driver so I eventually toned it down and smoothed it out with a sensored Viper VTX10.

Cool thanks I'll give that a try

I just recently put on a 6000kv HW motor on my B4.1 and running it at 25/72 and the thing absolutely rips, tons of acceleration and top end, too much even. I turned down to EPA to 75, I don't have torque or power settings but I set punch down to 3 from factory 7 which helped coming out of the corners. Also I would run a little drag brake because it is gonna be blazing fast it'll help you harness the power better IMO. Good luck, I honestly think that these buggies do best with the higher KV motors, as long as the driver can handle it of course.

Anyone with an inside scoop know when the big bores are supposed to be released ?

In my buggy I run a 4600 2 pole motor, it is a little smoother. I am geared 21/81. I also take the dead bNd move it to small. this helps the bottom feel smooth and the top fast. Brakez at 50 percent on controller and 85 on radio

I was lucky to get my hands on some of the prototypes. Lol. Actually I've been messing around with the TQ big bores (which are cosmetically very similar to AE). You will notice Hartson has a longer screw on the front tower, mainly b/c I found you need to space them back about 2mm so they don't rub. The rears fit fine, but I run a 1mm spacer on the bottom to prevent it from rubbing on the link. I have been runnin KYO springs and losi pistons in mine.

The pictures I've seen of Hartson's buggy look like standard V2 shocks.

Don't be hungry for big bores. When running for TQ I had both shocks and tested back to back on many tracks and in many cases on the smooth tracks with high traction not only was the feel better with the smaller shocks but lap times where just a little better, so depending on the jumps, and the way a track was this was more of a tuning option but in many cases I ran the smaller bore shocks.

HAHAHAHa god i love u chris!!! You always find a way to cheer someone up or make someone laugh at the dullest moments...

As for the team driver comment.. umm sorry buddy but i would love to beable to even race weekly on a reg basis.. but considering my health situation im pretty sure my life/health is more important than racing.. thats why i am trying to do everything i can to make up for it.. sorry it doesnt make u proud..

ASK for the Help you recieved nat the track from the "RACERS who put there car on a track" fellow team drivers thats what were suppose to do is help any way posssible thats what set THEM APART..

O and for you having my back ... thankyou but ill pass as i feel a little weirded out.. And just think like u said what favors weree done..lol

I hope you can forgive me and forgive my spelling errors as i am not up to ur level.. im just a mere mortal young adult who lives and learns from his mistakes.

Sorry chris and for the rest of u

To think I actually had your back on here a few months ago when you first started posting. Ok, if that's how you want it.

You're not over any point besides really not being able to put the laps down. Hence your lack of attendance at the tracks. At least the tracks where there is real competition.

I will never doubt your willingness to help others and your love of the hobby, but let's be honest, there's the old saying "Those that can not do, teach".

As far as me being a hard head and a knuckle head as you put it, I never denied the fact gluing the servo saver will work. It's just something I'm not sure my driving skills are up to, after all, I can put the front end into the pipes with the best of them.

I learned some things at Motorama from AE sponsored drivers who actually PUT THEIR CARS ON THE TRACK. And, guess what? I actually saw a difference in the cars handling. None of what I learned had anything to do with what you told me.

For the record, I highly doubt you forgot more than I know.

I'm not sorry for putting you on blast just now.

Now, back to our regularly scheduled B4.1 programming.

The most recent pics are the BB shocks. There are a handful of pairs across the US right now so expect to see more pictures begin popping up in the not so distant future.

Reports are that the are a noticeable increase in performance over standard shocks with BB springs.

Things are sometimes hard to tell, but these look standard. I guess I could be wrong.

In that pic those are the current shocks. A couple pages back is a pic of the new BB's. They have a Blue bottom cap.
