Stobe slipper gearing question
 

Well guys..I decided to get a strobe slipper, even though I've had good luck with the RR slipper setup. So here is my question...I'm running the following on the RR setup

13tP 32p
66tspur 32P

is this comperable for the strobe setup..
16t mod1
51t mod1 spur?

that's what neweuser said would be a good starting point.....
is this correct....
thanks

A 10 tooth with the strobe will get you about the same ratio as you RR setup

that seems awfully low.....are you sure....?
I'm also running Ue 8 spyder diffs
with a lehner 1920/8 motor and a 2095 micro controller...all on 12 cells in series

Well they're different,66/13 =5.07 and 51/16 is 3.18. The 51/16 is a more typical gearing (66/13 is low)but are you running high rpms?

What's the setup,diff ratio,approx. weight,tire size,etc?

BrianG's calculator is usefulhttp://www.scriptasylum.com/rc_speed.html

ok...here is a little more info...

1920/8 motor....rpm per volt is 3919
times 12 cells = 14.4v = 56433 for rpm
tires Team Losi Zombie Maxx tires
weight of truck...between 12-13 lbs
does any of this help

Cross postage there,my computer is screwed unless the forum's really slow.

Anyway,the 10 tooth would be right if you're happy with the current gearing.Yes it's low but you're running unusually high rpms so it works out about right speed wise for 12 cells,a little high really for the 12-13lbs.

Wow, that is low. But he is also running UE diffs, not stock....but knowing the RPM's your running Shayne, speed wise would be around the 10T, but you are gonna have tons of torque! You could bump it up a tad more though....right now your temps are cool so bumping up a tooth or two wouldn't hurt.

If you like and have room to go you can get a 65 tooth spur to fit the strobe slipper then get the 13 tooth pinion to match back up and have a storonger set up.

I ordered the 4mm shaft 13t mod1 pinion....and I will see how it does.....the gearing is pretty close to what I was running and on the 32p setup i could of gone as high as 15t....which would of been...
15t/66= 4.4
13t/51=3.92

which is pretty darn close....if I have to I can allways order a 12t or even the 10t....but I don't think I will have a problem now.....we will see.
also thanks for the help guys...much appreciated.

Did you change the diffs as well with the strobe?

He runs UE's with a RR Clutch and is getting the strobe....couldn't help but to talk him into the new era of strobe and dump the RR! LOL

yup...troy is right I was running UE diffs with the rr slipper, and now I switched over to the strobe slipper...thanks alot troy....lol....but I'm getting my revenge on ya...with the motor.....why do you ask..coolhand...am I missing something?...I've been using brian's calculator.....did I do it right?

Well if you run the 13 51 strobe set up. It is almost like running 17 66 combo in the 32 pitch.

I think I'll be ok.....what do you think.....should I email mike and tell him to switch my order to a 12t pinion?

Personally, i would email him and get both, that way, if one doesn't work out, you won't need to order another, you'll have it right there!

that would be fine....except i just phoned him and his answering machine said he will be on vacation till july 10th and at that time he will answer all calls and emails......

Well, someone must be there to process stuff. Or, jsut order with a note saying to combine shipping...

I'll stick with the 13t and if i need to I'll get the 12t...no big deal....

Actually, Mike is pretty much the only one that processes stuff...Well kinda the only one period :p. He will process all the orders on the week he gets back.

hey squee...what do you recommend...the 12t or the 13t.....just would like another opinion...that's all.

The question is did you like the gearing you had before. If so stick with it.
If you want faster then you can try alittle more pinion.

For me...I ALWAYS WANT FASTER! LOL, but agree, if you liked what you had and it ran good temps, than stick with it.

I would get the 12T and the 13T but chances are the 12 will be perfect. If i was only to get one, I would go for the 12.

I think that since everyone is suggesting that I go with the 12t, then I will email Mike and let him know and hopefully he can switch out the 12t in place of the 13t I ordered. I hope it isn't to big of a deal. I wait to hear back from him on the 10th...Thank you everybody for replying and helping me with the gearing question... and I'll let everyone know how it goes.

recieved my 12t mod1 pinion today, dropped it ina and took the truck out around the block, did several speed runs in 1st & 2nd, and wow I thought it was fast on 13/66...geared ( 5.07)...now at 12/51 ...geared (4.25) it is insanely fast and the controller still stays cool, the motor is a little cooler than when i ran 13/66..... glad I made the jump, thanks neweuser for giving my that extra shove....and to everyone for the gearing suggestions... it all helped......hope to see you all at the bash.... also thanks Mike for the pinion....

Yep, no prob. Kinda wish i kept it to myself so i could stomp you at the bash!!!! LOL :005: :005: :005: :005:

vey funny little man with chicken legs.....very funny, on another note hows the tranny doing.....email me if you can..
