I'm pretty sure he had gotten the aluminum knuckles to solve this very problem.

you mean these?....

That is one thing i have not had problems with. Never bent a dog bone or broke a front hub. I have pulled a pivot ball thru one of the front hubs but the car has been bullet proof for the most part for me. I try to stay away from to much aluminum, you just wind up breaking more stuff

Only thing is accidents do happen, and unfortunately the front dogs do snap really easily - they don't bend. I'll see what I'd get.

Your not kidding!

I race on on a large parking lot with large diameter PVC pipe hooked together with straps. I do 'POP' the pipe every now and again. I only break a few things, several dog bones, pop the pivot ball out of the hub and the side belt falls off now and again. i run the P-dub bumper which takes alot of impact and disapates alot of the energy. These are acceptable to me because their controllable by how I drive and easy to fix. I would stengthen these areas up more but the energy would be transferred to something else which could more difficult to fix. I do have sveral CVDs in the pit box!

I'm awaiting feedback from that guy who has the R40. He runs the car consistently and seems to have no problem with it. I'm amazed at how fast the car is with the stock setup, then again he is running a Sirio Evo 3. I'll see how much it will cost me for the package I'm trying to look at vs the other car someone is offering me. I'm in a debate over these two and I may need a new engine for my 8th onroad as well for racing. I'll have one practice and one race engine. Time will tell, but I'd much like to get back into the sedan scene.

I must have got one of those good ones. I have never broken a dog-bone..well once but that was when I let someone else drive my car (BIG MISTAKE). I have noticed that the side belt stretches quick, are there any other belts out there that are better than the ones it comes with (Doesnt HPI have upgrade belts?)

They did seem to wear a little bit, but not by that much. I adjusted the side belt tensioner for more tension.

Ive never snapped a dog bone , never poped a pivot ball , I have had the metal #50461 part that covers / holds the arm on the pivot ball come loose sometimes. Hasnt done that in awhile after the first assembly.

And the rear camber links strips. Thats about it for me. I do bend dog bones though....I normally replace but lately dont really care. Unless its real bad and noticable. I have the p-dub bumper and this is probably helping some now too.

But other than that , my old rdlogic pipe seems to take more damage than the car. My new pipe has yet to been touched. I think the new stratus 3.1 body might be a little more protective of it. My stinger barely exits the body.

I will be trying out the titanium swingshafts and steel from GPM when they come in. I only wonder if they are any stronger. Im actually not sure what the stock ones are....their pretty lightweight. I believe I also had a set of used 3racing swingshafts....they were quite a bit heavier. I wonder if any of these would hold out longer.

Default 2 Speed Gears.

I just bought a complete set of gears for the 2 Speed combination. Looking at all the gear combinations that is available, is there any specific combinations that I need to use? or could I match them up as I want to too get a desired gear ratio? Example, could I match the 21T pinion with the 58, 59, 60 and the 27T with and of the 52, 53, 54 T gears?


Secondly, how do you set the gap onthe pinion gears to the two speed gears. Do you mate them all the way or do you leave a small gap between them when assembling the engin to the car?

You dont want them to touch. Basically think of like 1.5 sheets of paper distance. Then roll the car and listen it should roll free and not make a tight scratchy sound. Good way to hear the sound is too intentionally set it too tight....

i went through a stretch where i broke 3 dog bones in one race everytime i tapped the boards...come to find out i had the set the servo saver too tight after a rebuild...loosened it a little and the easy breaks stopped.

just another thing to check on your own setup

I had the servo saver at the stock setting. Don't see how setting that too tight or looser will stock breaking the dogsbones. I'm gonna see what deal I can get for that R40 kit.

You can use any combination of pinions and spur gears as long as you keep the 1st gear pinions with the 1st gear spurs, and the 2nd gear pinions with the second gear spurs.

An easy way to set the gear mesh is to roll a strip of 20 lb paper between the gears and get it the mesh as tight as you can. When you remove the paper, the gears should spin freely.

im thinking if the servo saver is too tight then there is no "give" on the wheels during impact.
