Okay, IB's are good, kinda figured that. Thanks for the $.50 per bar info.

How strong are the IB batts? I mean with 7 sXs, will the BK 7018 still cogg if I set my external BEC to 5V? i.e. can the 380C-6L (69A peak I think) pull down 7 charged IB 3800's to 6V (need a volt to run my BEC) in "normal" use?? I expect the volts to droop as batts get exhausted.

EDIT: Anyone know if the $.50/bar would be the same as the "larger than deans" that are depicted on BB batts?

You shouldn't have any trouble with the LVC on 7 cells. The newer(year or so) warriors actually have a better voltage cutoff threshhold than the older ones. I tested a 9920 with a 6 cell stick pack and couldn't get the dreaded "cog" until the very end of the discharge.
Also, all the warrior car controllers have reverse-just a matter of programming.

Thanks Mike,

I'll make my "new" 3600+ packs all 7cell to try to keep that voltage up. I think I need it to push the heavy Maxx tires on the Stampede/380C-6L (just gotta find the right gearing). Many say the old/flaky software in the BK7018 isn't so smooth below 8cells (tho some say cheap 6cell 2400's were smooth).

I just want enough cells to hit 25+mph, enough to hit a ramp in the yard (short take off), anything else is gravy for me. My 16x2 Epic Intense gave it a good shot on 7 GP3300, but the 13T+ ESC de-soldered it's factory battery wire from the heat. Still works, & thermals, they just set the thermal too high & used 14ga. I think BK thermals at 110C, I'll probably add a cheap fan, easy enough.

I'll use your sticky thread for programming the BK ESC and turning its BEC off; that's where I learned about the convenient motor reversing too, thanks. I don't think I hooked up 3 BL wires yet that spun proper direction, some luck eh? :027:

As nice as that jumper is, doesn't BK come already with 3.5mm gold plugs, so motor reversal would be simple anyway. I think use of the plugs is a BK warranty condition. Not like I'm racing or want to solder, I happen to like easy disconnect for service.

Nope, the warriors do not come with plugs attached except for the connector to plug into the Rx.

Finally ran the Feigao 380C-6L on the BK7020 on 7cells (using homemade BEC, I do have to set to 5v, or I get cogging on elderly GP3300s). Soldered to perfection, it's awesome even on the huge wheels. Temps get to 60C on motor & ESC during speed runs with body on and 84/18 gearing. Ordered a Swami wheelie bar to protect the motor. Seems to be ~40mph on the Maxx tires... silly fast... Seems like an 8T brushed.

Can use current batts now & bettter ones later. Tall grass, or anything else, is no problem; bottom torque requires a wheelie bar.

My T-maxx is out-of-service (620MG Blue Bird steering servo keeps cracking cases on Moab 40's, & I can't find the newer BMS black cases), so I'll be running brushless for awhile & charging batts! Great to have an electric as strong as my nitro for when I can't get to the parks.

EDIT: I forgot to glue my tires... made a big difference, to say the least. I think I'll mod my BEC to allow different voltages, 4.8/5.0/6.0 for different packs and allow passthru batt voltage when batt sags below the setting (& beep or something then too, so I know, cogging is nearby).

Thanks for the great products & advice :027:
