I have recently purchased a Team Br00d Pro 19T motor - I am running a TRF415MSX - but have been having serious trouble with overheating racing on carpet indoors (track size is probably 7metre x 20 metre, quite tight)

I am running a 108 Spur - And tried a range of 28-32 pinion -

Here are the ratios

28/108 - 8.281 (Final Drive Ratio) - 3.857 (Primary Ratio)
32/108 - 7.246 (Final Drive Ratio) - 3.375 (Primary Ratio)

I know the usual way of working it out (max speed by 3/4 length of straight) I seem to be over gearing (the motor really is untouchable after a race!)

- Can someone suggestion the correct final drive ratio? or is there something wrong with the motor?

First off.....is this with foam or rubber tire's? Going off the info you supplied I'd assume that it was rubber but I don't want to jump the gun. As stated above what type of motor is it?

Erm.. I don't think it actually stated what wind... I think its a 19T Quad.

And yes I do run on rubber.

Brood 19T quad mag

I am running a Reedy Yokomo based 19t Quad mag from Brood with a 19T 18.5g arm

I am gearing on 6.90 overall ratio on a 69 spur gear and a 25 pinion in a TC4 using CS27/22 tyres on a indoor medium sized track.

I think I am still geared a little high as the speed comes only at the end of the straight.

I am running GP3300 batteries typical 1.170 numbers nothing special.

What can iIdo to get more punch out the corners? New batteries or I am I gearing all wrong in the first place.

Motor come off hot but not too hot to touch.

What do you think eddieO?

Default reedy 19t quad mag

EddieO

Are Trinity xxx le mans brushes still the hot ticket? (if you can afford them) or are people moving back to 767 and 4499's?

on an outdoor asphalt track, about 35meters X 30 meters, we gear our reedy 19turn motors anywhere from 5.7 to 6.2 final drive, are we over gearing our motors?

Default Brood 19T quad mag gearing

sorry forgot to mention i was running on a indoor carpet track!

Outdoors I would run 69/30, or 67/31 on a TC4.

Less rolling resistance and bite on a tarmac track!

Monster stock, Red/Red is a good starting point.....for carpet, we typically spring heavy for most drivers, while asphalt or offroad use less tension. Brushes, like to use the 767 in most cases...

For the 12 turn Ti, I would start Purple/Red.....4383 brushes...

New batteries are always good, especially the new IB3800 packs, which have crazy voltage and runtime....

The Reedy Quad magnet ALWAYS runs hot...

In fact....remember this with motors. If its fast and doesn't fade.....the temp it comes off the track is irrevelant....fast is fast, so who cares if you can fry an egg on it.

XXX brushes are very popular....I don't think they are the hot ticket for big race stock class sedan racing....but for local racing, I would use them, save a ton of money! In offroad, the xxx brush is the hot ticket.

IB3800 packs are selling fast....so if you need some good cells, jump on them....remember, our stuff is matched at 35 amps.......

Lastly, I would like to welcome multi national champ Alex Lopez to the team....he joins national champs Peter Robinson and Travis Schreven as past stock champions....



Later EddieO
