Motor frying
 

Hi

at dudley this weekend i was frying motors evety race they where coming off really really hot i started with a 19t which gotreally hoti started with a 23 on a white spur and came of really really then i wnt to a 24 and that came of slightly cooler but still to hot. Then i went to a 25 and was even hotter again. So i went back to the 24 for round 4 with a new hole in the shell for cooling. This also got hot but i only ran for a few minutes as i was getting interferance. So i thought it maight have been my motor just not powerfull enough so i changed it to my 14 V2 and i was doing well insane amounts of speed i was in third place chasing the 2nd place man when the motor came unsoldered cus of the heat i was runing this on a 23t pinion and a white spur. What the hell is wrong why is it getting so hot.

A:eh?:

your way under geared, when i ran a v2 dynasty in xx4 i ran it 29/78

Oh I was told by carl lathem and doom to run it on a 23/24 on a 78 spur. Ill give a 29 a go.
Thanks

Ashley I run a Spashett 9x1 V2 on 21/78 so yeah you could be under geared:rolleyes:

If you go dy Doom's normal recomendation think it's 9-10 over wind, so you shold have been on 28-29.

That still doesnt exsplain the 14 though i was runnign that on a 23 and that got the hotest. And tyre man it is very true he was going on about adding 9/10 to the wind.

78/23 gives a overal gear ratio of 8.26630
78/24=7.921875 thought that should be ok ish om a 19 turn

ash sorry to break this to ya but a lot of the probs with ya motors was down to drivin you had some bad luck this is the biggest motor fryer simple physics say that starting your car from a standstill will use far more energy (heat) turn your punch control down on the speedo to free a bit pace of the car it may be more drivable smoother and faster laptimes;)

I is its on 2 out of 5.

Cut some vents on the shell, i had a lot of overheating problems in mine until i did this.

Not my lovely new shell.:(

I may try and fit a fan and a small heatsink.

A

So ull blow hot air onto a hot motor and speedo....
Get an old shell and try it before then.

Ok ill try that southwell.

But i have to say this was an awsome car to drive i had a little understeer but i didnt do anything about it as it was the last of my problems but i think my final was going really well i was just as fast as a tamiya 501x and i have to say i think i wasnt doing to bad as i had only driven this car for about 2 minutes before dudley then for about 10 minutes during the day not including my final. But it is an awsome car it really was easy to drive i has tight on the corners but i think i need to do something about the way it rides the bumps as it was strugerling slightly over the bumps and i need to sort out my understeer. Its a shame about my motor in the final if it had holded out i think i would have had second.

A

ash ur car wasnt as quick as that 501x i watched yor car and tamiya ps i drove the tamiya for a few laps in the final and it was ballistic pity it was too soft and yes it was me who lap ya with it and then nick lapped you with it so also ur car wasnt too bad across the bumps they where just evil

just wait until the speedo gets back from repair....it goes a lot faster when it doesn't release it's magic smoke
Needs recharging.....what's best... Europe smoke or the cheeper Chinese stuff?

The first tamiya lapped me the second didnt.

A

we both drove thesame tamiya we swopped half way through the race:D

The white car i think it was a tamiya. But the blue car which i knew was a tamiya didnt lap me.

A

W.A.P.A.N ....from Japan ;)

the blue car was an old cat300

I know i heard the lad who's race it was shout hay come up here have a go with the or what ever but i am 99.999999% sure didnt lap me cus the person who was helping me said let the white car thought as he is lapping you but he didnt shout for the blue car and i know you took and early lead from me but i bought the gap back in again when he crashed. But i know you didnt lap me as i was ahead of you when i stopped.
