If you’re in the United States and looking for something to do this weekend, or you feel like taking a break from the weekend races to check out what’s on in RC, look no further than the RCX 2011. Held at Fairplex, Pomona, the is THE place to be if you care even an ounce about your hobby. There’ll be lots of 1/5 scale action this year, with Zenoah Engine’s  NATC Championship Series, and even a charity raffle for a highly-modded Baja 5T by Baja Addicts (I wrote about this earlier at Donate $2 to win a $10,000 fully-modded, custom-built HPI Baja 5T! Best thing is… You don’t have to be at the event to participate in it… World-wide hobbyists, read the post to find out how you can be a part of the raffle), it’s no wonder why Large Scale News is doing LIVE coverage of this event. RCP tracks will also be dishing out their mettle for Crawler demos and Kyosho & Auldey Mini-Z racing.  There’s just so much going on..

Youtube User “Fidas2” of Portugal totally pimped out his Mini-Z racer with the following parts list:

– Custom diff made front ball diff with 36 teeth spur

– 30 teeth pinion (also custom)

– Motor: stock PN Anima II

– Mr02 PCB with 2+2 stack (not enough because it blew in this pull). Next try will be 4+4.

– 4 NiMh AAA 900 mAh batts.

– Atomic RM motor mount.

– ball bearings of course.

– Modified Tamiya speed checker, with Venon Speed meter.

The result was a top speed of 135km/h. Check out the Youtube video here:

Subsequently, the same hobbyist made another video, and this time with a perfectly balanced rear axle, light weight wheels and tires, custom  motor, new FETs and 4xAAA powerfull TRP 900 mAh batteries. This time, he hit 174km/h on the Tamiya Mini 4WD Speed Checker.

This is both rather phenomenal considering it’s small size. While Fidas2 failed to beat the fastest known TC4 out there, which did 196km/h on actual asphalt, not a similar speed dyno.

Another consideration is that the Tamiya Speed Checker had little or no rolling resistance. If there was, we cannot ascertain if the user had programmed a RR constant in for the testing. Visually, it seems that it merely measured the speed of the wheels, which, when positioned on a hard surface, could manifest as a significantly lower top speed.

However, I’m still keen to know, what if they substituted the 4×1.2v Nimh batteries with 4×1.5V Alkaline cells or 2S Lipo 7.4V pack, what would the result be?
