Neu 1512 pinion fitting issue

[wallot]

the motor has so huge diameter that i am able to fit only 18T pinion

i need to use also 16T and 14T but cant position the motor as it already touches the transmition and cant move any further.
for 16T i need to move the pinion closer to the spur about 1mm and for 14T 2mm
any advice?

i am thinking of sanding the transmition case but dont think that I can take 2mm out of it

18T
14T

Is this in the emaxx? Maybe you can mod the motor mount for it to fit.

[BrianG]

You probably won't want to do this, but what about dremeling the motor fins a little where needed?

[pinolelst]

Bigger spur available ??
Shaving the fins off the motor case might look bad but is probably the best solution.Not sure if I like the idea of weakening a transmission case by shaving it.

well bigger spur is available but its 65T which is too big (have strobe with 51T)

its emaxx with trinity motor mount. the problem is i need to get motor closer to the spur and making new holes in the motor mount wont help. if the motor did not have fins it will fit so i guess i will have to dremel them a bit unles someone comes with better idea

[pinolelst]

Perhaps get an even larger pinion to use with the 65t spur to maintain the same gear ratio ??

sorry ...just throwing stuff out there to see what sticks:002:

Have you run the motor yet? If not, possible talk to Mike about exchanging it for one without fins?

[BP-Revo]

Try the motor on the other side of the tranny.

I know that one side of the tranny is bulkier than the other...

[wallot]

with 65T i have no chance to get same gear ratio as i have now with 51

I like the motor with fins it should help in cooling it

i tried the other side of tranny - the gap is smaller so i will just dremel fins a bit and be ready to go

still have to finish custom cooler/mount for the quark. cant wait take it for spin

51/14 = 3.643 to 1
65/18 = 3.611
51/16 = 3.187
65/20 = 3.25

Looks like you alreay have a 18t so use that with the 65t to get basically the same ratio as 51/14.
And 65/20 is pretty close to 51/16.
A guy at racing uses a 65t spur with the strobe without problems.

Thanks Patrick

that sounds good but isnt the 65T spur so big that fitting large pinions becomes a problem?

[Serum]

With a 65T/18t the distance (heart/heart from motorshaft/strobe) will be 41.5mm. In other words; too large. you need to adapt you motorplate with the 65T to make it work.

Shoot Mike an email, perhaps you can swap the finned Neu for a non finned, like Squee suggested.

[wallot]

i want to keep the finned version :)
adjusting the motor plate is not a problem, but is the ofna pirate 65T spur direct fit onto Strobe? from what i have seen in the forum there need to be some adjustments done

//i was searching for a ofna 65T spur and found only steel version which is something i do not want

[Serum]

No, it needs some love before it fits..

[Patrick]

Oh
The guy at racing uses the 65t because of his Hacker C50. He told me it was about 3600kv, so he uses a smaller pinion, I think a 16t. I didn t look at how much mounting room he had left though.
