well i got say i am about over this truck.
i got the bce chassic on hing pin insert shock bodys and anything eles the team guys are running.
but i cant find a set up this car works every weekend it just get wores.
any ideas on set up would be great clay indoor track.
the truck is lose one side the track then traction rolls on the other. i need something that works i had enought.

but, everytime I have seen this on the Losi at the track it ended up being one of three things:1. swaybar set to pull one arm higher than the other: adjust the endlink in or out
2. the new alum arm mounts somehow 'crooked' when tighten: loosen them and make sure the arms are free as you tighten screw small amount left then right repeat, measure left and right toe
3. droop screw gouged or moved somehow and left to right droop is not equal
I would also check left to right shock rebound
Mine is planted on indoor clay , aaron lane setup ALL the upgrades with gold barcodes

The weight of the pinion is insignificant compared to the side load the pinion is putting on the shaft trying to turn the spur gear in a heavy truck like the SCTE. The motor is capable of producing over a HP. That's roughly 200 in/lbs of force. The bearings on the Pro4 motors are also roughly 50% closer together than the 550 motors. The same force at the pinion will cause the shaft to deflect at a greater angle in the Pro4 vs a 550. By doubling up the bearing you are reducing it's load by 50%.
The bearing that failed in my motor destroyed the retainer. The only way this can happen is overloading the bearing and spreading the balls apart until the retainer fails. The bearings in the Pro4 are probably close to their design limit under normal circumstances, add the shock load from landing a jump at full throttle and you could easily overload the bearing.

A longer motor should preserve the 'non-pinion' bearing, and if you double up on the pinion bearing you have a more robust motor.
That said, no problems at all on my Castle 3800. I still might do the bearing trick though to help with longevity.

The longer the motor is, the less the bearing load is on both bearings. For a given side load, as the motor increases in length, the bearing load on the bearing closest to the pinion will be equal to the side load, and the bearing load on the far bearing will be close to zero.
This assumes a steady side load is being applied and does not account for any dynamic effects.

ok needing help here..... well my friends ordered bce chassis 2 weeks or so ago. well after complaining to there email they were told chassis would arrive last thursday. well they never showed. so while being down to run his truck he looks on ebay the other night and see's finally some are back up for sale. so he hits buy it now thinking its a person selling an extra or something. there was a logistics issue with the purchase and he gets email through ebay from bce chassis. they dont ship the 2 he ordered direct from their website but have them to sell on ebay???? what gives. does anyone have a number to contact these people? any help please.

look im not trying to bash bce im just trying to help my friends get responses from bce. i just dont understand how if he has them to sell on ebay that has to ship in 5 days or less how my friends get bumped 3 weeks. so please dont take this as a naggin thought.

Do you know for sure it's Bill from BCE that is selling the chassis on eBay and not some else who bought them before you and is now reselling them?

Not the fastest or most responsive, but worth it. If you need one for a race, make sure to order several weeks out (maybe even 1.5-2 months out) to make sure you get it in time and have time to install and practice.
Like I said, some experiences may vary, but my experience wasn't anything unusual from what I've heard.

If the ebay seller is "ultrabc" it is coming directly from BCE, even though it says Tustin, CA on ebay. I bought from that seller and it came from Bill himself and I ended up talking to Bill when I had some issues. BTW, Bill took care of my issue and was great to work with.

Been running indoors. What wt oil, pistons, and springs are best for a dusty hard packed track with big jumps? Im going to be running emulsion as well. Thanks.

Same exact response and time frame they said i would get mine. I also noticed the ones on ebay. I actually was gonna come on here to ask the same exact question.
