Meltdown
 

Last weekend I took my brushless buggy and truggy out to the local track. The ambient air temp was hot (108 degrees) even for Socal. I had a converted Kyosho Kanai 2 with a Feigao 8XL, Maxamps 4s2p 6000mah, MM, UBEC and 46/13 gearing. The truggy was a converted CEN Matrix TR Arena, Feigao 8XL, TrueRC 4s2p 8000 mah, MM, UBEC and 46/11 gearing. The buggy ran fine all day, temps never got over 150 degrees on the ESC or moto. The truggy was running hot, I have a spektrum telemetry unit with it set to vibrate at 180 degrees. After 5 laps the Spektrum started to vibrate, as I brought in the truck it thermal'd and came to a stop. When I got to it the temps were very close to 200 degrees on the motor and 220 degrees on the ESC. After a cool down, I tried to run the truggy and no go, I checked the ESC and found that one of the wires (white one) had come unsoldered I assume from the high temps. After cooling, I reattached the wire and the truck ran fine. But it still ran hot so I am going to retire the truggy and move all the hardware to my Brushless Revo which is a few pounds lighter and see how it works out. The truggy is a bit heavier but I had it geared down and yet it ran way hotter than the buggy. Just for future reference any ideas why the truggy ran so much hotter than my buggy?

Hey, how about posting some pics of the truggy? I've narrowed my choice down to one of these or an LST2, but I'm leaning towards the CEN.

JThiessen, here ya go. The picture of the brushless truggy is old, I am no longer using the Novak 4.5HV system, I currently have a Mamba Max and Feigao 9XL in there.

Looks nice! Lots of room on there.
Any idea on the weight?

JThiessen, with wheels (Mugen) and tires (Proline CF) but no battery or body the truggy weighted in at 8 pounds 14 ounces. Recently I changed the battery tray for one that was larger (to handle a TrueRC 4s2p 8000mah lipo battery), and the weight went up to 9 pounds 2 ounces.
