motor upgrade im new to mardave racin

[markrobinson86]

i have a mardave mini and am new to the hobby. i would like advice on a motor that will improve the performance of my car as it currently runs the standart mardave 540 motor. i want to upgrade to a motor that is faster but not very costly can anyone help me please

regards mark

There is a company out there that makes 540's but with a different armature in them, they fly!!! Not shure on the name of the company tho.

Hi Mark,

Glad to see your getting into mardave racing:

Go and look at the Mardave section on this site, there is a post called "Hop ups for Mardave v12's" (or a title similar to that).

A chap named Mark Stiles has posted a very good note informing of all the things to do with your Mardave and what motors to look for

Apparently, the V14 motor which you got in your kit is the fastest legal 540 available, according to Mark Redmond... my opinion is 'bullshot' with a capital I - he's cheating and not admitting.

Apparently he ran his under water for 8 to 10 seconds, motorsprayed it to stop rust and uses Orion lube on the comm. Mark Redmonds car is faster than mine and punchier with a 27turn 24degree stock in! It'd be impressive if I didn't feel that as his is the only one so fast it is unfair.

I have had most success with a RS540-SH, but what used to be fast is now much much much slower than Marks 'fettled' V14 motor. Makes me sick.

woah, there mo! I think you need to be absolutely sure that Mark has indeed fettled with his motor before labelling him a cheat.

I have seen his car, and it is stoopidly quick, but he has not necessarily opened it up and fettled with it.
I used to run my motors, with batteries attached, in a pint glass of hot soapy water, and then spray them with motor spray. They were faster after that, as my motor tester proved, and incases significantly faster, but they soon died.

Just like marks did last week.

[Mark Stiles]

There's nothing illegal about water dipping motors, as long as you don't open them up or tamper with them.

If I use the kit motor (V14), I am about two laps slower at my local club (circuit has a 10 sec lap). For the past 2 years I have used the mabuchi rs540sh, as has everyone at my local club and at the nationals.

I find a couple of comm drops before each race gives you that little bit extra at the start, and keeping the bushes well oiled helps as well. Other than the odd bit of motor sparay on a cotton bud to clean the dirt off the comm, I don't do anything else to my motor.

The rs540sh motor should be quicker than a 27t stock when running on 4 cells, as the rs540sh's are 22 turn. I'm almost as quick with my mardave as a stock touring car round my local track!

[Chrislong]

Sorry, BUT....
I didn't label him a cheat, I said "In my opinion" which is different - see I can be diplomatic. He swears blind he isn't cheating and I can't see any signs except his car is INSANE.

I know I am cheating by using a 27T stock - but I admit it and don't care since Jubilee going to separate the classes. ha ha.

Im just voicing my opinions, I know I could be wrong cos I usually am.

Does anybody reading this have any thoughts on this? Is it possible to make a V14 go SO fast with punch (geared 18/46 on tarmac)

Chris

[Chrislong]

Sorry Mark I forgot to comment on your comments.
I liked the RS540SH too, a lot of us used this motor doing same as you said and we were all fast and equal = fair racing/fun. Suddenly this V14 motor has dropped MR's average lap by a second and he is miles ahead of any of us. = we're all frustrated and curious.

On Friday I tried the 27turn stock = slightly faster (geared lower to allow it to rev more) and a few people were trying a 19t SPEC motor and faster/driveable still.

Guess which motor won! the V14.

Im not accusing him of anything, my opinion is it mustn't have a 27turn armiture inside or zapped or something, but not accusing him. If he was on here id be keen to hear how he has done it.

Chris

[burgie]

Mr Long you said " - he's cheating and not admitting."

so I think you are labelling him a cheat! your opinion appeared to refer to the V14 motorbeing the fastest . . .anyway, the simple fact is, we can't catch hm no matter how we try, but I'm sure you spotted his motor "go off" on Friday night. It was even slower than my car!

I dont race mardaves, i used to but found them a bit boring, i wonted more speed and some thing a bit more complecated.

[Chrislong]

Ok, I give him his dew, it is a fast car he's got and we all want some of the same - its just so fast I can't beleive that what he says he has done is all he has done but there are no signs to proove what I say.

Has anybody else found a way to make the V14 so fast? "No"? That is the sole reason why I question him..

Maybe if somebody can answer this it'll help Mark Robinson (who started this thread), oh, and me.

Didn't notice his car go off in final, I know he pulled me in from a long lead I had and I was really trying, grrrh.

Im not sure if they go off because of the voltage drop and the speedcontrol reserves power for running servo - not sure atall, but happens to all of us - even when i run a 27t stock. ???

Chris

[Mark Stiles]

And you're pretty sure its a V14 he's using?

It could be another make of 540 with a silver can. ???

What about cells, and speedo; what are each of you using?

[Chrislong]

Hi Mark,
Yes it is a V14 for sure, he says it has stronger magnets than the RS540SH and it certainly feels like it does too. He does not keep it secret that its the V14, dipped in water and dropped with Orion and cleaned every race.

We are both charging from Integy charger (the top one version 6), GP3300 pushed, matched, zapped, squeezed and squished cells and both using MRT VX Sports speedcontrols with powercap. Ballraced rear axle, lexan shells, geared 18/46.

I have seen one V14 motor match my legally fettled RS540SH, but this one is another level. I think Marks car handles better than mine slightly - but the difference is both on acceleration out of corners and top speed - its a huge difference.

Any ideas?

[Mark Stiles]

Nope!

The only way it would have stronger magnets would be if he had them zapped. However, this requires the can to be opened (i think!), so that is ruled out seeing as its a sealed motor!

Lewis taylor should be putting a video of some racing at our club on here soon. When he does, compare the speeds of our cars to yours. They should be fairly similar considering you've got basically the same kit as me (apart from gearing and speedo. (we run on a shorter track, so I gear at 14/50)

[Simmo]

Hmmm, sounds dodgy to me... I thought you can Zap a motor without having the can split? as I have been offered in the past - a zapped Mabuchi and it looked unopened....
I thought the V14's where'nt meant to be as good as a 540Sh?

[Chrislong]

Me too.
When I changed to RS540SH I felt an immediate power increase, then when I learnt all the tips it was faster again! So im puzzled as there is no reason why all other cars should e slower than this one.

What drops do you all use on your comms? What is best?

Im using Trinity Bearing Lube, found it works better than the Trinity Comm Drops!! also seen TQ orange work - suprisingly. Plus I always clean comm with brake and clutch cleaner from motorworld.

Any ideas I can try guys?

Chris

[Chrislong]

Additionally,
I think we get away with gearing on 18/46 because it is a smooth tarmac and long track, so no resistance on tyres like carpet. Might give the 50 tooth spur a try on Friday.

When i race on carpet, still on long tracks I do drop to 16/46 with the RS540SH.

me and my mates will try anything to equal the speed of this V14, unsuccessful so far..

Chris

[burgie]

Chris, maybe MR's motor is fettled, but he does not appear to have opened the can, does he? The car is insanely quick though.

Maybe he has just been lucky and got hold of a really good motor? It will be interesting to see how long he keeps the speed up, dontcha think?

[Mark Stiles]

Why don't you make it so you all have to run the rs540sh motor. That way, there can be no arguments, and you should be able to tell if its been tampered with by comparing the speeds from car to car.

I use LRP blue factor comm drops. I'd never put any bearing oil of any sort on the comm, as I've tried it in the past and the motor glowed and smoked everywhere. I also gota big purple flame when the oil burnt off the comm!

[burgie]

the club is now running two classes, modified (anything goes) and standard, where RS540sh have to be used. It's in this second class that MR runs, and as you look at his motor, it is an RS540 tpe can, that appears not to have been fettled with. It is the esxtreme speed that he is attaining that suggests it has been fettled with.

He is easily as fast as a 19t tourer round the track!

[Doomanic]

If he runs in a class with the RS540SH as the control motor, why is he allowed to run a different motor?

[Mark Stiles]

If you have to use the rs540sh for the class he does, then that doesn't mean he can use the V14 (or anything else). Although the V14 is still a 540, it is a different motor.

The rs540sh should have the following stamped on the can;

MADE IN CHINA
RS-540SH
T0079x22 (some have T0069x22)

At nationals, if this stamp is not on the can then the motor cannot be run.

Chris,
Make sure you're running the rs540sh in reverse (as they're faster in this direction!), ie connect the negative speed controller wire to the positive tab on the motor, and run it so the drive is on the left hand side when looking from the back. If you have it connected the other way around, then the car will be noticeably slower.

[Chrislong]

I thought the classes at Jubilee were split standard and modified = standard being 540 BRCA legal motors, and modified is anything goes, 4 cells etc..

The ideal meeting (in my opinion) would be: booking in fee an extra quid or two, every meeting you are given a motor to use at random when booking in. Between meetings the motors are checked, cleaned and replaced if needed and all you can do is clean them - nothing else.

That would take away the advantage the regular winners have found, and give the mid table drivers a good chance of progressing.

But still curious how this V14 is soooo ballistic..

Mark Lambert - if you don't have anything constructive to say please don't say anything at all!!!!

the V14 motors are slower.. i have never ever seen a v14 match let alone out perform one of the RS540 SH motors.

some motors however are faster than others, if you took a batch of rs540's and dynoed them you would see quite a large performance difference in them!

Mark or anyone in the 12th oval section help me with this---- is it true that you can swap motors with a competitor and pay them £5! i think this is correct or the rule is similar to that... if you are really unsure you could try that rought!

[Mark Stiles]

I think you can make a protest, with a fee of £10. If your protest is upheld (ie if the motor is stripped and found to be illegal), then you get your money back (I think). If the motor is stripped and found to be legal, then you lose your £10, and have to pay the person for the cost of the motor.

Or you could do the easy thing and ask to try his motor in your car, and pay him a small sum for the trouble!

[Chrislong]

Cheers guys,
He is willing to fettle motors for people for a fee if asked nicely, so worth a consideration.

But Friday, my 27turn stock came up trumps, it seemed faster than the 19turn spec motors in same race. i think me running a 14 tooth pinion against there 18 tooth pinions gives me an edge - til they try it!

But took FTQ and nearly a track record, good start to final til the BL >:( >:(DY fragile wishbone gave way on first lap! might try getting some nylon ones made up at work.

Chris

[Mark Stiles]

I run a 14T at any track I go to. I find that my car doesn't go as well with any other gearing. I occasionaly use a 15, but no bigger than that.
