I made another order and this time I Just bit the bullet this time and did 3 day ups. For 4 batteries it was $43 dollars shipping. So that puts the cost of each of my batteries at around roughly $51 a pop while still getting them fast.

Honestly I did the cheap way first, cause the spring outdoor season hasn't really started up in in Pacific NW, so I had time.

ah I didn't see you responded already. That's good to know it can take them 3-4 days to UPS.

Funny thing today while I was practicing... I had my brake set to 70 and front flipped when I mashed the brakes coming off the first long straight into the turn lol. I bumped that down to 45 and put my drag brake at 10. Not sure if I like the drag brake or not. I've been running only 2wds for a long time and tonight was my first attempt with the 4x4. What a difference. Gotta learn to drive all over again.

I wonder if your current limit is set to low and not allowing enough voltage to hit your motor when it needs it causing the temp issues. I run my current limiter at 85%, no drag brake, Timing set to 10, Push set to 20 (which I may bump back down to 10 or back to 0).

I also run a 14T pinion and my motor is not hot at all when I get off the track after an 8 min main. I haven't temped it as of yet, but if I can put a finger on the endbell and motor can and leave it there longer than 5 seconds....I'd call that good ;-)

I decided on my settings after speaking to Larry Ward (Team Losi Driver) and he told me his settings as well as Adam Drake's and Rhonda Drakes (AD runs a 13T pinion and RD runs a 12T pinion!). Larry has been running a 14T for awhile now and it works well most places.

I'm currently running my CL at 40%. Lowering it does not cause temps to rise.

Drag break on the other hand will cause temps to climb and is not needed on the SCTE anyway. It has enough inherent drag as it is.

Thanks everyone for your input. I will remove
To drag brake and see how it goes.

On a separate note, do you think the Losi diff grease adds for friction to the drivetrain and when switching over to oil in the diffs would reduce friction making it more efficient and inturn make the motor not work as hard? Just wondering.

Thanks,
Greg

I did a test. 7 in each diff ran the truck in 75 deg weather no wind three packs 6000 60 c current limit 80 no push control no drag break no timing set at min throttle profile 3 14 tooth pin 4600 pro 4 rx8 and it came off the track three different times at 180 motor and 97 speed control. went home changed to grease in all three, next day same thing three packs and the motor was 147 speed control was 84 so the grease was about 30 deg less . motor has so much magnet drag when you go down the straight and let off it almost goes sideways turning. just thought I would put this out there for your information. also promatch batteries has 6000's for sale is local and under 90.00 get it in three days go racing.

BCI chassis experience....I got mine in 5 days after ordering, both emails were returned same day, had tracking number, all holes lined up, no short screws included for motor/center diff mount, fit-feel-finish very nice. I'm on the second race week since the full rebuild and the truck has never run better. I don't really notice much difference in handling and the truck jumps great w/o nose dives. It would be really easy to drill 3 new holes to move your battery back if you really wanted to. Overall, I am very pleased with my choice to go with the BCE but I'm sure all the aftermarket chassis are really nice.....

ps- I race on a tight technical indoor track.

Well i ordered a 50c 2s lipo for this truck so what pinion should i start with on the 4600kv with the Toro 120 amp.i have a couple of Mod 1 pinions from my truggy i have a 14t to 16t pinions.

Its the stock spur gear on the SCTE .

This was with 40/15 gearing. I dropped down a tooth on the pinion to 40/14 and I was still having the same temp issues with the 4600. I run on a big and fast track (see video that a fellow racer took below).

So, my question is what gearing are you guys running and what temps? Preferably those who are running the same motor/esc setup.

Thanks,
Greg
Greg that track looks awesome. Size wise though it's not "huge" compared to an outdoor track that some race on. Gearing wise on that layout I'd be at a 13T since there isn't a long straight. Rather it has a lot of short shoots and tight turn areas.

What esc setup are you using?

Wow you run it at 40%? That seems pretty low, but I bet you get some killer run-time out of that sucker! ;-) I figured like all things electric, the less voltage they get the poorer they perform...so it was a shot in the dark. Glad to hear the current limiter doesn't make that happen though just in case I need to lower my setting eventually.

As a last post on this subject of chassis, I will include a couple shots of the outdoor track I race at. If you look careful you can see the big triple near the middle, a little to the left side this is the jump where any balance issue likes to show it's face. You come off a couple turns, then need to get up the speed to hit the triple; with a tight line it takes everything most setups have when geared to make 10 minutes and not overheat. Not that it cannot be done, the stock chassis handled it quite well last year and much more consistently for me. I never did run the TLR, but I know a lot of people that love it. Anyway like others said enjoy your purchase, don't make problems where they are not if it works it works if it doesn't try something different
