What motors does everyone have?

[GFWilliams]

Hi everyone,

I have just ordered a 15x2 orion motor and was wondering motors other people run

Also, what speed do you recon my car will go roughly with a 27t pinion?

Thanks guys

Hello, I'm currently running a Peak 14x2 in my RC10B4, but have a Novak Velociti 6.5L on order (no more brushes yay)

Can't really comment on the gearing for you without knowing what car you have (and if you race it).

[Roop]

Without knowing the spur gear you have, number of cells and either chassis type or final drive, it's impossible to say how fast the car will go.

I run various motors in different cars including the following :

Stock Silver Can 540
Tamiya Super Stock RZ (23t)
Team Orion Katana (23t)
Tamiya Super Modified (13t)
Team Tekin Mini Rage (6.8kV brushless)

The Orion motor is used for spec racing in the Swiss Indoor Touring Car Championship (SITCC).

novak GTB 5.5 R brushless in my xxx

The days of the brushed motor are coming to an end my friend. I'm getting back into RC after 10 years away and for it the ONLY choice now is LiPo cell and brushless motor. Cheaper in the long run and more performance gain.

This is not necessarily true. A brushless motor and ESC combination still represents a siginificant additional expenditure over brushed versions. Until the price gap narrows considerably, there will still be a market for brushed motors in r/c cars.

For example, the SITCC which I race in operates with a controlled specification of motor, wheels, inserts and tyres to ensure that the costs do not escalate and it isn't biggest wallet wins.

Eventually, brushless motors will take over from their brushed counterparts as demand grows and costs come down, but until a kit manufacturer such as Tamiya starts to release brushless motors and ESCs in their mainstream models, it's no time to say that the end is nigh.

It's the same situation for LiPo batteries. Until your local model shop "Super Deal" comes with a LiPo and compatible charger instead of a generic 3000 NiMH and basic peak charger then the NiMH (and even the venerable NiCd) aren't dead.

Thanks for the replies guys

It is interesting seeing what motors people have got

I have got about 5 27x1 motors as my brother used to race in a class that used them

rougly how much quicker do you think the car will be?

Thanks alot

[bumrar]

it will certainly make a noticeable difference, make sure you get the gearing something like right tho, if the motors getting very hot its probably over geared

[GFWilliams]

sorry for the novice question - is overgeared set up for too much acceleration or topspeed?

Thanks

[bumrar]

too much top speed, too bigger a pinion

Have been 'retired' from the racing scene for a few years now, but my favourite ever motor was a Fantom 19t super stock. Great torque and as quick at 12T modifieds on a tight track. Not all that reliable but great performance.

[slartibartfast]

2 jet engines, 12lb and 18lb thrust, one in the process of being built.
a few brushless and some Lipo's

tons of old glow and diesel engines, some fourstrokes, did own a Wankel but sold it.

Dependant on class and conditions i used to alternate between a 14 quad, 13 triple and a 12 double. I also had a few 27 singles for indoor stock class racing. This was back in the day when the best batteries that you could buy were 1700 scrc's

I should say if yu are going from a stock motor to a modified one then your speed will increase greatly. Make sure you don't over gear it though as you will cook the motor

Fair enough I'd accept the comment on brushless as these are pretty expensive at the moment, but as someone who's coming back into racing after 10 years, the LiPo route is cheaper. If I was to go the 6-cell route I'd need to buy 4 new packs and a decent pack for serious racing would set you back approx £30-40 each. Then the charger which again can be cheap or expensive. Where as with LiPo you only need 1. I can buy one for £80 and then the charger which is no more expensive than a normal one. So just based on cell costs, it's cheaper now for startups to go the LiPo route

[bumrar]

brushless is also getting closer price-wise to brushed set-ups, if you add up the cost of a decent speedo, and a decent modified motor, plus if you add in the cost of replacement brushes, getting your armateur skimmed, and then replaced when it wears out, its probably not much different to the £130-ish I paid for a novak GTB set-up. Okay, so I did have to get it from America, but so what?!

[motormania]

The club I'm going to be racing at only race stock to keep costs down for everyone. Its indoors on carpet and they look pretty fast even for stock 27T motors. So I shall go the brushed way for now. I think that market forces will draw most to brushless within a couple of years by which time I should have got my racing skills back to where they used to be and will then treat myself with the brushless setup

Happy days. I used to run an Extreme 13x6 or an AGR 13x3 in my Predator!

I have still got my pred, its a TTech 95 Pro which I upgraded with a plastic chassis and GP rockers, the original carbon chassis was a work of art but the gearboxes kept working loose . Awesome car that made a fantastic noise they were also quite rare. I fried an ESC in it once generating massive amouunts of smoke as it went down the straight

I never raced against another Pred, they were all CAT 2000's, which model did you have mate?

I had an original Predator that I was lucky enough to have factory backing for. That was then fitted with upgraded parts as they introduced them. Unfortunately I, and everyone I knew who had one, kept having issues with stripping the original driveshaft pinion and diff gears but it was a great bit of kit when it worked - more than enough to see off the majority of YZ-10s, CAT 2000 et al. I gave it all up when I went to uni so never got the full benefit of the factory's work over time when they ironed out all the issues and made it more robust. Still have it sitting on the shelf.

[Bungleaio]

You were lucky having the factory backing, i was supported by my parents. I remember the kit being well over £300. I have also killed a few of the main gears on the diff. It's still got one in now as I can no longer get replacements. I did manage to pick up a car from some one a few years later so I've got loads of wishbones, driveshafts etc but it ate the crown wheels!

Fantastic cars, shame they went under.
