back to the ntc3 bumper solution:

this is not a good idea of you race on an asphalt track that uses pipes or track-dome. The bumper will actually increase the impact of the crash, because it will wedge into or under the pipe. The stock bumper has a design that will make your car airborne in a wreck, which will atleast give you a chance to recover from the crash. Also, if you have anykind of track dome style pipe( the inside of the turn is a slope with a 30 degree angle) the extra width of the ntc3 bumper may lift the inside tire off the ground and you will lose traction. In a way this is logical theory, but you should notice a difference in your Pro 4's reaction to the wreck.

It's not just Monster motors. For me it's Trinity motors in general. Monster, Binary, P2K2...had problems with them. Drop in a Peak, Reedy or Orion...golden. I did make some headway into possibly figuring out the problem tonight. A friend of mine suggested soldering the hood-tabs to the board as well as the screw-hook on the one side the contacts the metal area on the board. The results...glitch free operation of my Binary that wouldn't even run 5 feet previously without major glitch. There is something about the Pro4 and it's components that make it very sensitive to interference. Anyway, the suggestion came from a friend who also had major glitching of Trinity motors in his brand new Losi XXXT MF2. Apparently he didn't have the problems with his MF1 so that's kinda odd. Hopefully the glitching problem is solved.

Have you guys with glitch problems CA glued your battery slots on the chassis? Could be one cause, or at least at to a problem.

Hello Nexus,

I tried it last year and it was really good! Only thing I changed was the springs as the DHI setup was really soft because of the low traction conditions.... I used Losi purple front and Losi green rears.
It is a really good starting setup and I am sure you would like it!!

Cheers Mate

Might sound silly, but does anyone know the gf/mm to lb/in conversion? I want to list the HPI springs in lb/in like the rest of my springs. Or if someone has already done the conversion on the spring set already, that would be very helpful.

Thanks,
