okay, yokomo mr4-tc md (1/12th touring) and an 88 tooth 64p spur with about 56mm foams.... I am running a Sureshot 19t arcor D5..... What should I gear it at? BTW, I am racing and am using 4 cells... I was gearing about 40tooth and it seemed kind of powerless... is this too low? lmk thanks!

hmm, you got me!

seriously, does the motor feel hot at all when you are running it. From what I gather from talking with Big Jim, the best thing to do is to gear the motor so that it tops out about 3/4 ( estimate here ) down the longest straight, as long as the straight isn't insanely long as I have heard of some motors not liking that.

you may want to see if there is a thread for this vehicle as they may be able to help you out better.

How are you liking the mini?

I am just not having much luck with keeping my quad mag from burning up the brushes when I run 767s.

I think I must be way overgeared. I am running a 29 tooth pinion with a 72 tooth spur. After talking with the LHS owner and he is also running a TC3 now I should be running about a 26 to 27 to be on his range.

What's the FDR?

I like them, but alot of people hate them. Most of the guys that run the reedy 19t at my local track run gear ratios that are very close to there stock motors, 25mm rollout. Then again I've seen a few of them delaminate.

He's running a 6.2ogr which is way off if he running full size tires(unless your on a hugh track). Run a 6.5 or higher gear ratio. That's why your cooking your brushes.

Actually I was the one running the 6.2 gear ratio...

He is using trimmed tires, my calipers should be in soon so I should be able to calculate roll out then. If someone could post the equation for that, that would be great.

I should also look into a good alignment bar. Big Jims is probably tops, but $40 is a bit much right now. Is there one that is cheaper that will get the job done?

(tire diameter in mm x 3.14) / (overall gear ratio)

P.s. If your track is short you may want a radio closer to around 7. Just ask around the pits, they'll tell you what to run.

Thanks for the info.

The track has a 96ft straight but a good amount of change direction turns for the track we have been running recently.

So far my LHS and a couple of XRay drivers run the Quad Mag. I think I will start with about a 23 tooth pinion and go from there. I so far have the 23, 24, 26 for pinion selection.

This has got to be the fastest 19 turn I have run to date.Its a D5 based 19turn with laydown brush hoods and 767's.24 degrees of timing and 6.3 fdr.I cant find another motor this quick or this illegal!

If your track allows anything when it comes to 19turn then this is the one you need to try.Banzai Motors makes them this way if need may be.Or they will do them with p94 brush hoods.The Epic outlaw 19's are not even close.

Ive just got a Peak Dynasty (standup) and am totally stuck for brush and spring choice. i used it for the first time last nite and it had killer torque, but i seemed to have to be gearing it stupidly low to get any top-end.

any tuning ideas?

Cheers

I am assuming you had to go with really big pinions. Thats the nature of torquey motors. You just have to be prepared to go up. Reedy Quad Mag is even worse.

i just got a reedy 19t quad mag and was wondering whats the best springs to use? i already know about the brushes.

thanks

I RUN RED ON + AND GREEN ON -. TRINITY SPRING. MOTOR IS GREAT AND RUNS GOOD.

I just got mine a couple days ago...

How do you have it geared with that combo?

So far I have had the best luck with trinity purples on + and -.
geared at 6.00 and could probably go a tooth lower..
