Burf2000 Posted December 5, 2011 Posted December 5, 2011 Why are they not remote controlled? They all seem to have cables out the back? Quote
Alasdair Ryan Posted December 5, 2011 Posted December 5, 2011 Why are they not remote controlled? They all seem to have cables out the back? I wondered that to,it might be down to the power function signal breaking up. (not so good in a race if this happens ) Quote
Burf2000 Posted December 5, 2011 Posted December 5, 2011 I wondered that to,it might be down to the power function signal breaking up. (not so good in a race if this happens ) I would be more worried about the cable drag or getting caught and the extra weight it adds? plus you need to run with it? Quote
DLuders Posted December 5, 2011 Author Posted December 5, 2011 @ Burf2000: The "tethered" Lego Technic offroad vehicles have their battery boxes OUTSIDE of the vehicle, thus leading to lighter weight and greater speed. Outdoors, the sun's powerful light sometimes interferes with the Lego Power Functions infrared (IR) signal. The weight of the electric extension cables is a lot less than the weight of a battery box and PF Receiver. One has to run along with PF-controlled offroaders anyway (to stay within IR signal range).

Sheepo Posted December 5, 2011 Posted December 5, 2011 (edited) Why are they not remote controlled? They all seem to have cables out the back? Easy, without batteries the cars have much less weight: less weight = more speed One of them has 4 RC motors :laugh: I love this competitions!!! Some time ago I tried to make a competition like this in my city, but was very difficult to find many people near... Edited December 5, 2011 by Sheepo Quote
Jurgen Krooshoop Posted December 5, 2011 Posted December 5, 2011 Wow, these buggies are cool and fast ! Quote
Zerobricks Posted December 6, 2011 Posted December 6, 2011 These sure are crazy and fast! And thanko the exterrior power supply, they can have more motors, less weight for batteries and multiple external batteries for more current! Quote
