About the electronics:

I wanted to avoid the Neu cogging thing and find out how my old Hacker would do.

So I put the Hacker modded motor in it (C50 12L but screams) and geared it 10/46. It was fast as hell... easily the fastest thing I saw down the straight all day. I don't know what the deal is with this motor but it's always been fast... but runs hot. I thermalled with it in practice... motor and esc both over 200* :eek:

So it was back to the Neu. Now I didn't put the 1512 back in just as a trial, because last fall when I raced it with that motor and the MM that was still in the car, it would start shutting off (reboot, come back on) after a few minutes for no apparent reason... temps were low, not under big loads, etc.

So I tried the 1515 just to see if the motor was the problem. It did the same thing with the 1515 so something is wrong with the controller.

So I took both the 1515 and the MM out of my truggy and put them in the 8ight. Everything worked pretty well.

I only had it cogg at start up a couple times that were very noticeable... never a problem while racing.

BUT, I did see like two or three times where it did the "brake glitch" thing... where it seems to cog very breifly while running, not from a standstill.

Oh and after the races were over I took a couple laps with a fresh spur gear fix... and I may have done something to the controller. Not sure yet... gotta try it again today. :013:

Um yeah... can you say ear plugs and eye drops?

It's very cold too so it's a mix of running heaters and having the window open for ventilation. Catch 22.... smoke or cold.

But it was good to race. Next time I'm bringing some headphones or plugs. A cool thing is that they broadcast the announcer via FM radio so you can listen to what's going on and block out some noise at the same time.

I didn't have a radio so I couldn't hear very well... thus the mistake i made thinking my race was over and pulled off early.

Jolly... yeah that was fun being competitive with the fast guys. I belonged in the A for sure, but no way I would have won the thing... I would have been thrilled with top 3. There are better drivers there than me... but my car was capable.. who knows maybe with a great run I could have challenged in the A.

But I need to sharpen my driving... or drive 20 min without a mistake.

Well lack of practice on the track don't help. I think you may have got better
and faster as night went on. Better luck next time.


Peace!

Hey, I forgot to mention the temp and runtime data stuff.

Keep in mind the track was cold, like 40*, so it's way different than in the summer. I didn't use any fans.

And I kept the lipo pack nice and toasty in the pits. I kept the pack wrapped up in a little electric heating pad while charging and waiting to race... kinda like the tire warmers on road guys use. So the lipo stayed @80-90*. That looked funny but worked great. :)
motor temp, esc temp, mah charged back after the run:

1st heat: 125*, 120*, @1400mah
2nd heat: 162*,125*, 1680mah
3rd heat: 128*,128*, 1350mah

geared 16/46 every run... runtime varies a little depending on how many warm up laps I run etc.

But in general I was running about 3 laps warm up and the race is about 6 minutes once the time is up and you take the last lap. So I would say @ 7 minutes ave. track time. The thrid one I stopped early and the first one I think I was taking it easy.

So it looks like I was using around 230mah per minute... very happy with that. In a 30 minute main at this rate I would only use 6900mah.

NO DOUBT!!!!!!!!!!!!!!!!!!!

This shows me more than ever that we need the new software... and more so the Monster Max.

EDIT: because I still had issues even though it worked well for the most part... shows the potential IF they can iron out the bugs.

Thanks guys....]

BG, they have the sportsman class too... there was like 20 buggies in that class too. Some of those boys can't make a single lap without crashing at least twice, lol....

This was up at Waterloo...

Lol, that sounds like me! I should have made my username "crash". I think I'll stick to HobbyHaven for a while. :)

Ahhh Yes! Sportsmans class... Thats more my driving level too.:032:

When I see folks drive like you did in that video you make it look so easy. Then when I get out on the track and try it myself its a total mess.


I can't decide if its more fun
to make it...
or break it...

Nice driving. When I have my brushless out on the track I have the problem of too much power, and always end up dialing it down via the radio. After selling my brushless 1/8th, this new mamba maxx is making me regret it.

looks good, I hope my 8ight will look that good when it finally hits the track. also great idea about keeping the lipo warm. I know I have tried my 8ight outside lately and the performance is not nearly the same now that its 10-20 degrees out.
