I did notice air bubbles in those broken arms???
Dont let the arm problem upset you, if you run on a track with small jumps and soft pipes you will not have a problem, all my front and rear breakages have come from a very large triple and im sure if i doubled and singled the triple the arms might not break but for me that defeats the purpose, if i wanted to double then single i would run stock.

Since i started running the BMAX4 3 rear arms i have not broken one, so if the rears are all you are breaking this will fix it.

Anyone one have any suggestions regarding front and rear diff oil weights per low to medium bite hard packed dirt track conditions.

Thanks

I run 8F 4R and it was perfect on a loose slippery low traction track.

Was running 7f and 5r but I think it could do 10f for more on throttle steering out of corners.

Thanks fellas! Got another suggestion as well from another gent whom suggested oils very close to both of your suggestions. In all, basically being closely within the same realm.

Before these suggestions I popped in 5k front 3k rear which I think I will go ahead and run, thus if anything to break the diffs in. I am not the fastest wrencher in the world being on the other end of the spectrum. With that being said, I try to dial in a happy medium diff oil combo right off the bat as changing diff oil in this buggy is going to take me some time. Rather be running than wrenching

Any thoughts on the 5k front 3k rear diff oil combo as a starting point would be excellent. The buggy is built thus I am hesitant to take her apart to change the oils, however I will if any advice provided points to this combo being to light. (Track is very very hard packed dirt! dirt! and more dirt thus quite dusty and slick. Traction does pick up when moisture hits the track but for the most part a dust layer will always be in the forecast)

Thanks for the advice and any thoughts on the above as I really appreciate others input.

Best,

Norse

In general, on a 10th scale wheeler with gear diffs, I have always been told to start with 7k front 5k rear, especially cars with slippers in the middle, and its always been a good starting point. If and when my hop-ups show for my kit I got, I plan on running that.

I'm running 5/3 on mine and it feels great. Plenty of steering and has great rotation. I'm running on a med bite turf track

Jealous of you north westerners and your turf tracks, but LRH has insane 100% clay grip, so turf/carpet setups generally work very well there.

Thanks fellas much appreciated. I almost stayed at 5k front but ended up going to 7K front and left the rear at 3k. I be running her on low bite hard packed dirt. Can't wait!!!

All in all the advise which I greatly appreciate seems to be real close regarding lower bite and diff weights.

Have a great night and may you all enjoy a Happy Holiday season.

Ya the tracks are nice. 2 local tracks that use the same tire choice and 1) is wide open throttle and the other is short and technical. Both are fun tracks

You guys that picked up a YZ-4 from R&D Japan scored a deal. 18% is gone and replaced by 8% so now you're looking at $450 or so out the door.

After a bit of a hold out Copeland caves and picks up a YZ-4. Look forward to hearing a comparison to the D413, ZX-6, and 22-4's that you've owned man. One of the only people I'm aware of who can speak from experience as you've owned each of them.
