Dans lego Posted January 3, 2014 Posted January 3, 2014 (edited) Hello, I was just wondering if anyone has done a rather fast RC car WITHOUT the use of an RC buggy motor or the new servo motor ? --Cheers , -Dan Edited January 3, 2014 by Dans lego Quote
tibivi Posted January 3, 2014 Posted January 3, 2014 Yes, very light/basic and small chassis with an L motor and 40 toothgear on 8 toothgear, it works pretty well :) Tibivi Quote

Theo van Vroenhoven Posted January 3, 2014 Posted January 3, 2014 May be you could try this one? http://www.jurgenstechniccorner.com/yellowracecar.html Some technical data: Length: 38 studs Width: 17 studs Height: 14 studs Number of parts: 728 (including the remote controller) Drivetrain: XL-motor with 3:1 speed increase.

MrNumbskull13 Posted January 3, 2014 Posted January 3, 2014 I done one one with an xl motor and an m motor very recently. I geared the xl motor 20-12t but one sure you could go 24-8t, mine weighed about 520 grams. :) Quote

tibivi Posted January 3, 2014 Posted January 3, 2014 thank-you, I only have one problem ... I only have a XL motor .. or a few M motors ? I first did it with the xl, but when the L came out i replaced it. The steering was done with a m motor and a hockey spring for return to center. I also used the lipo batterie for saving weight, but it was easily changable to a normal BB. Quote
JM1971 Posted January 3, 2014 Posted January 3, 2014 My bike has 2 L motors bolted together, if you combine that with a AAA/Lipo battery box it should go some :) Quote
MrNumbskull13 Posted January 3, 2014 Posted January 3, 2014 (edited) Hello, how did this perform and do you have any photos of the chassis by any chance ? It was quite fast & I could take some pictures of what's left of it, I'll post some links in a few mins. [edit] here is a view of the xl motor, the universal joint ran to a live axle http://m.flickr.com/#/photos/92293857@N05/11728930214/ And here is a view of the m motor, the steering was geared 8-24t. http://m.flickr.com/#/photos/92293857@N05/11728536965/ I used the 56 x 26 tires, use them or a little bigger and try to keep your car under 500g and you should be able to gear the xl motor 24-8t.

piterx Posted January 3, 2014 Posted January 3, 2014 i would use 2L motors geared 2:1 for not more than 600g Quote
