Hi.

I don't have access to CRC parts but have plenty for AE's.

What AE parts are usable for a CRC Gen XL?

Thanks.

Hi Guys
I have an Ass 5.2 and my question is which way round to mount a hobbywing v3.1 1s
I have tried it on the left facing forward so the wires are on the outside of the chassis but that means the sensor lead is also on the outside Nd therefore vulnerable. Other suggestions / how do you do yours? Any pictures would be good

Here you go...this is what I did.

Anybody know anything about the new Cali Copper compound tires from T/M?

G'day all

I have dug out of retirement my 1/12th CRC carpet knife and I am looking to get it running again .

Last time I used this car (some 2 years ago) I was having problems with the speed controller over heating and switching into standby.

These are the specs of the Motor ,Battery and esc
Motor : Speed Passion 3.0 1 cell 4.5R
ESC : LRP sxx competition
Battery: cant see brand but it is roar approved and 1cell 50c 3.7volt

I remember someone telling me I need to change my gearing as this was what causing my esc to over heat.
could someone recommend a gear combo for my car as I am unsure as to what I need to order.
Cheers

I think about 100/26 is pretty common on our indoor 100x48 carpet tracks with ~42 mm tires and varying amounts of boost.

Thanks for the quick reply but sorry should have said in common with a lot of uk racers I run my batteries across the chassis rather than in line hence the speedo is on the left as you look from the rear of the car.

Anyone else help please

The gears I currently have on are 69 tooth main and 30 tooth spur so should I be going up as in a larger main gear with the bearings in it and spur gear ? or smaller?


John

Try 26/96. The ratio you are currently using is only a little more than what I was using with 13.5. How hot was your motor getting?

1/12 rules!

The motor isnt getting hot at all just the esc .
Also whats the go with the pitch ? Is there a pitch specific to an engine or do you just need to make sure that both gears are the same pitch ?
Thanks for your help so far guys
John

Both gears definitely have to be the same pitch. I have only used 64p so cannot comment on 48p. I believe some use 48p with mod motors and/or on asphalt tracks. They seem to be a little tougher for those conditions. Edit, also you want to shoot for a mid 30mm rollout with that motor.

(Tire diameter x pi) / (spur/pinion) = rollout

Also, a 4.5T is a little on the Hot side for a LRP sxx competition, if grip/load is high

General rule with 12th mod
Hot motor=under geared, spinning too much rpm
Hot Esc=Over geared, tall gear putting too much load into esc

Obviously the new escs with heat sinks/fans can handle more load, with the extra gift of added weight

FYI guys, since I run the CEFX chassis and former Z4 wheel set I recently learned that the wheel sets are now produced under a new brand "pro-one RC". Steve Dunn is the new owner and excellent to do business with. I'm glad he is continuing to provide one of the best 1/12th scale rim designs ever produced.

But ever more impressive is the 1/12 th scale tire truer adapter he sells. Finally someone has produced an adapter for ever 1/12 th scale rim produced. It even works for the Yokomo rims, Pro-0ne (former Z4), Jaco, BSR, CRC....

I'm confused with roll out .. what am I actually measuring ?
And which gear should I change the small one off the motor or the large diff gear
Sorry for the dumb questions not really sure what I am doing here lol
