AAngel, you run a 7xl with MM in a 1/8th buggy on 4s? What kind of temps you getting? I wanna do that soon (lehner later), buggy is in the mail.

I'm running a 14/46 gearing and 12v fans (straight off of the 4S pack) on both the esc and motor. They've never gotten hot enough to cause me to grab the temp gun, so I really can't say. I run the heck out of the setup on the track too.

If I had it to do again, I think that I would have gone with an 8XL. The 7XL is almost too much for a track or even bashing. I rarely get to full throttle and when I do, it isn't for long enough for the buggy to reach top speed. I'd go with the 8XL for even lower temps and better runtimes.

AAngel, I to am from Lousiana. I live in Baton Rouge. What track to you go to? I use to go to KKR, but haven't been able to make it lately. I think they renamed it to something else now though.

I usually run at the track in St. Charles. It is maintained by St. Charles Racers club and is a decent track. I've looked into going out of town to run, but it looks like no one will let me, although I've never been to the track in Baton Rouge.

What track in Baton Rouge? Krazy Kajun Raceway (KKR, now something else) will let you run.

The only Lehner I have seen is a 1940/7 in a E-maxx on 12 cells nimh, and it runs much cooler than the 7XL in my E-maxx, not than mine gets super hot though. So yeah, from what I've seen the Lehner hardly even gets warm.

squee,

I'm going to have to check that out. I'm not a big racer. I "bash" on our local track and have raced on occassion, but do like to keep my buggy (and now truggy) in race form. It is, after all, the best way to get around the track. I don't race much because our races take place on Sundays and for me, that's my day with my son when we don't have anything else to do, and that's more important than racing. What discouraged me from going out of town is that when I meet people at our track from out of town, they usually don't have nice comments to make about my setup. The last thing I need is to go through the time and expense of making a trip only to find out that I can't run.

Patrick,

did that lehner that you saw have a heatsink or fan on it? I have to run both to make sure that my motor doesn't get to hot on long runs.

It has a rc-monster heatsink (I think it's an L size-it doesn't cover the whole motor), no fan, in an all aluminium car. It's maxd out's e-maxx.
Our races are fairly short, but I think it would still keep quite cool in a longer race (compared to my 7XL anyway).
