__________________________ Posted December 3, 2014 Posted December 3, 2014 I just got a copy of 9398 and I'm wondering if there are any good mods with 2+ XL's for propulsion. I did some searches and couldn't find anything that resembled 9398. Quote
Blakbird Posted December 3, 2014 Posted December 3, 2014 I'm not sure why that would be an improvement. The L motor was developed with this application in mind and it works perfectly. The crawler has the power to go over anything reasonable. An XL motor has more torque but I don't think you'd be able to use any of it, and it would take a lot more room. Quote
Mikuri Posted December 3, 2014 Posted December 3, 2014 (edited) Here for complete instructions. I have a 9398 with those right now and it's a nice upgrade over the L-motors. But nowhere near my 4XL... :P http://www.brickshelf.com/cgi-bin/gallery.cgi?f=529528 Edited December 3, 2014 by Mikuri Quote

I'll start with Sariel's gear reduction, change the wheels, and see if I can still use that extra torque! There's a reason why designers have put L motor in the Crawler.
