mgt 4.6 with 2250kv motor 80 hobby wing ESC on 4s 5000MAH packs unable to teat at time i have a steel spur and i keep stripping pinon.....i now a have a 25 tooth HPI flux pinon so this may work out fine

You should grab a couple of mike's pinions I've never stripped any of them.

The Serpent with 101MPH is very impressive :) Any vids of it?

Nice cars. Might want to look into getting rid of the lipo Rx pack on your DM-1 and run an external BEC, Castle's can run up to 9V.

even the guys at castle recommended it to us

yeah it grainy but we are working on get cam setup a least 4 views and i am making a speed tram to show the speed on 6 in led display

who is mike ?

As in rc-monster mike. Best pinion I have ever used. Ran a steel spur early on and his pinion destroyed the spur while showing no signs of wear itself.

ok cool thanks

Mike is the owner of this place!

Any close ups of how you did your motor mount and mounted the battery trays? I have been sitting on a mugen mrx-3 for some time and want to convert it to electric

THANK YOU VERY MUCH FOR THE PICS...Just what I was looking for!

I would assume you have no reverse with the one way bearing these cars have. How are the motor brakes working for you

yeah no reverse...the motor brakes works just fine ..... i use jb weld to lock the spur gear..have pics i you need

They recommended you use the Castle BEC or the lipo RX pack?

yes because we are doing mainly high speed runs and we were having issue with the DSM RX. so we used external battery to help us with that and so far it has worked fine....

yes please...that would be terrific :yipi:

I have been siting on my mugen for quite a while and your build has inspired me to dust it off and start the process again. I have already stripped it down and removed the nitro gear so it is ready for a mount and battery trays. I really like your idea of the dual trays and anchoring it to the center of the chassis as well as being one piece as well

i find this works best for me i also did this to my ofna dm1 and they both are holding just fine i hope this help u out

thanks again for the pics..much appreciated. What is the point exactly of locking the spur anyway. Just curious

I forgot to ask...how does it handle. I know it's very fast, but on a track how would it do compared to a stock nitro version. Three of my friends have the mrx-3 as well and I would love to show up with mine all converted and see how it would compare

locking the spur use can use drag break instead of another servo........also keep in mind that this was a 2 speed and we are using the 2 gear which in on a one way bearing. which will not engage unless the 1st gear get up to speed ..hope this help

well it handle great but you will have to set the punch down some so that you want spin out from a dead stop or learn to really feather the throttle....it is ridiculous fast. so if you setup for a track i think you will be very happy

On my mugen I already removed first gear. I will try the drag brake set up as well.

I know all to well about punch control as well. My mbx5T is set at 70% to help reduce wheel spin and prolong my battery with my 1520 5S set up.

Have you tried your set up w/a 4s set up? I like the 4 or 5S set up w/a 2650 castle or Tekin motor. I would prefer to use 4s to help keep weight down but, 5s is just more fun!

thanks again for all of your help and thoughts

well we are trying to go as fast as we can so were using 6s setup for now when we get more guy with 8th scale setup we will go for more of a race format .....

where do you guy's run?

we run at Household Essentials 5895 N Lindbergh Blvd Hazel wood, MO 63042

here a Google maps location 38.76417,-90.371154

hope you live here we are always looking for new people

Wish I was closer but I'm all the way in NewYork...

2.5 years ago I made a BL track as well. With a upper-shassie I molded myself in CF I was able to pack the 6s Lipo-weight in the center of the truck (i had to move the drive train slightly as well).

I still drive it from time to time. The problem is that the total lipo pack has to be less than 4" * 4", so the selection is limited. Motor was the Lehner 2230, ESC MGM-compro.

It's mighty fun, but requires some space...

You are so right about the space. These cars accelerate so quickly that the edges of your track seem to come out of no where
