Anybody have any tips on tuning 1. Slim can motor car. It's one of the class's with the club that I am attempting to race with, and I'm not even sure which end points ahead let alone making it hunt. :lol: Routed wood tracks of coarse.

Thanks
Randy

Randy is it modern F1, and which car in particular, as there are differences in the motor shaft lengths , such as the Lotus has a longer motor shaft than the Mclarens if modern F1.
Any special, club rules would be helpful. Our club races 50s,,, early 60s, late 60s, 70s, and modern F1 so I may be able to help , but need a bit more info.

Bob it's the 2014 Nico Rosberg Mercedes. FF 050 motor. Stock axles, hubs, bushings, PG or YD, slot-it guide. Ialready have the slot-it guide and the YD's.

Thanks

Ok thats good I take it you are running no mag, which meand weight is crucial on these cars.
They are pretty quick for the weight and can be quite erratic.
when taking the body off, you will see there is not much space for weight, but under the motor ther is a small amount of space for thin lead. Also slim pieces along the side of the motor will give some weight to the back end. Just behind the driver is another small pocket , but the important one is in the nose under the area where a magnet can be put. If memory serves me it is a round hole for a round magnet.
I used a circle punch and put in a piece of lead there to help keep the guide down.
The Wheels on my Mercedes are smaller than the wheels on my Mclaren and Ferrari so the tires may be a loser fit.
Glue them up after truing the wheel and then just take the high points off the tires.
If you go too far you will have a smaller outside diameter than your competition which means less top end . Ialso have the front wheels just touching the track so they roll as the car moves. And fix the front axle at that point. I try to keep the braid as flat as possible for deeper guide depth too.
If you are using a slot it screw in guide , then try and set the guide tight enough so it still swings like a pendulum when holding the car from the guide , but a bit tight to assist in limiting the back end swing in the corners. Check the pinion on the shaft to see it is close as possible to the crown but turns without restriction. Yo are after as little friction as possible here so gear mesh and break 7n are very important. Glue the bushings in place so they dont spin , and if you still have a lot of axle slop use the
crazy glue fix. Running the motor in on the ff motors serves no real purpose as they dont have traditional brushes, more like fingers so no carbon to shape. If you can weigh the car and set the balance at about 55% on the back wheels and 45% o n the front.
its about an average starting point which you can fine tune from their.
With these particular cars, getting the balance using the least weight is preferable.
If I can think of anything else we do I will let you know. Oh and Check the crown gear runs true without any wobble or mishape in it as it turns . You can do this by hand. And you can checkmthe wheels for wobble at the same time.
Good Luck Randy

WOW!!! Bob. Thank you very very much sir. Greatly appreciated
