Losi 2.0 Conversion

That is unfortunate news. I just got my new 8T 2.0 and converted it ( http://www.rc-monster.com/forum/showthread.php?t=19101 ) with a Losi plastic Spur. I can't stand the sound steel on steel makes and was hoping the Losi would be as durable as my old Kyosho's were on my CRT.

Did you burn up only one? Any chance it was just some bad plastic?

Dave, the gear failure was kind of strange. I ran Kyosho plastic gears in my truggy/buggy and what would happen is I would knock off a few teeth from either landing with the throttle on or heavy braking coming off a big jump (both are mistakes). With the Losi spur it looks like it melted, or at least the plastic softened. I had an issue with my last run of the day (when the spur gave out) where one of my eagle tree sensor wires got caught in the rear drive shaft. This could have caused binding, heated up either the motor/center diff causing the spur to get soft. I didn't temp the motor on the last run because the sensor that got ripped out was the motor temp sensor, and by the time I temp'd it with my handheld Raytek it had been sitting for a while and cooled off. Until I hear more feedback on how the Losi plastic spurs hold up I will stick with my steel spur. I am also going to try a 2200kv motor to see if I can get my temps down to an acceptable range.

Well, in a few more weeks off-road should begin here in the northeast and I'll be happy to give you feeback on the Losi spurs. I plan to try them in both buggy and truggy and hope for the best.

Dave, yeah let us know how your vehicles perform. As for me I am going to switch to a lower kv motor. The 2650kv just runs too hot for SoCal summers, so I am dropping down to a 2200kv motor which I have used in the past with good results (performance ans temps).

Update:

I have been using my MMM 2650kv motor for the last month or so and just have not been able to get any consistant temps. No matter what gearing I tried the temps seemed higher than they should be. So I decided to change out the motor for a 1515 size. I had a spare TeknoNeu 1515/1.5D, so I decide to install this into my buggy. The TeknoNeu 1.5D I have is a square can, so I had to remove some of the material from the side of the can. I have found that the 1515/1.5 runs cooler and I can use more gearing options because of the added torque. The extra wires are for my Eagle Tree data logger sensors, they are just temporary and will be removed once I get the motor/ESC/Battery temps where I want them. Also I mounted a 40mm fan to the top of the motor to help with the cooling.
