Gold plugs/pinions
 

Which gold plugs do it get for a 8xl/9920 setup? The "High Amp. Gold plug 5.5 mm, 150 Amp" or the "3.5mm Gold plugs"?? Is one type better than the other?

Im going to be using 16 ib3800 cells if that makes any difference.

And what type of pinion should i get? im using a 64 tooth traxxas spur and stock slipper for now. Should i get Mod1? what size bore should i get? How many teeth should i get? I want it to reach around 45-50 in second gear.

Thanks for the help

You need the 5.5 mm plugs, for both the motor/esc and the batteries/esc. (the 8XL allready comes with 5.5 plugs soldered to the motor, but you only can get pairs of them..)

Yeah, a mod 1 pinion/spur would be wise to do.. you need a strobe slipper to make it work then.

It takes a 51t spur and a 14t pinion. (45 mph)

oh ok cool 5.5mm it is. I'm gonna use deans connectors for the batteries to the esc cause all my packs have deans on them already.

i was going to get the strobe slipper but funds wont allow it at the moment :( That will be my next and hopefully last hopup(Yeah right! lol)

So i get the "5mm bore 32 pitch pinion gears"? might try an 18 tooth, is that ok with the 64tooth spur? How do you work out the gear ratio and how fast it will go? I also have the supermaxx 8 spider diffs, does that effect the speed?

no, i based calculations on the ue diffs. (those are 43/13 stockers are 37/13)

64/18 would do about the same as the 51/12

How do you work it out serum? Or is that a Serum Secret?:p

Sorry mate, i wanted to share this document with you.. somehow i forgot in my earlier post.

It's just a simple calculator i made for a centerdiff powered maxx, with 43/13 diffs, i changed the gearing ratio for 2nd speed. (it is the gearing ratio of the gearbox and the diffs, it excludes the pinion and the spur, you can change those in the left two columns

cool thanks, what programme do i need to open it up? cant open it at the moment

winzip, windows XP has got it built in though.. the file is an excel file.

sorry i ment the programme to open the file, but i just found out its excel but i dont have excel lol just my luck! i'll try and open it up with microsoft works spread sheet or something lol. thanks

Serum I just saw on the BK website that the plugs on wanderer serie 20 are 3.5mm..I also thought the plugs were 5.5mm.. Typo maybe?

there is an excel viewer available for download. i don't think you can edit the file with it though..

yeah, i thought they are 3.5's too, because of this.. But Batfish/Joe and Mike say they are 5.5's...

I saw that thread too, then I checked on the BK website. They are 3.5mm.. Maybe Mike can tell us something.

Yeah, i didn't quite understand it either.. Somehow i can't imagine they are 5.5's, even the 2250 motor uses the 3.5 plugs..

Ok just wanted to make a test with my 1930/7 motor, ue diffs and 17/72 gearing.


17 / 72 / 5.79 / 145mm / 1875(kv motor-what do i put this to?) / 19.6 V for 16 cells 14.4V for 12 / est speed 41mph for 16 cell.

Im unsure about what to put in KV motor and gearing ratio
