30mph? How?

[nitrostarter]

Ok, so a State Trooper moved in across the street since he was displaced from Hurricane Katrina. I finally caught up with him to use his radar. I made some passes for him and the best he shot was 30mph. When he told me that, I looked like :W: . I was hurt.

Could that radar be right? I thought people were hitting 40mph easily with a 9L? I need to look for a GPS.
I also used Aqwut's excel calc. sheet and came up with like 29.11 mph. I thought I was missing something so I ignored it.

What gearing are you running?

[MetalMan]

If the motor was running at a good temperature (indicating proper gearing), my best guess would be that because radar guns are made for real cars, the radar gun couldn't get good enough contact with the E-Maxx to give an accurate reading.

EDIT:
I just read that you said that with the spreadsheet your speed came out to 29.11mph. There has got to be something going on with your gearing. Go up a few teeth on the pinion, and that should do it.

howd ya gear it? Maybe you need a new setup! how about i buy that esc off of ya and u can get somethign new! lol

[nitrostarter]

I meant to put the gearing in there. Slipped my mind. I'm runnign 16/66.

The motor gets pretty hot after a full run, but I wouldnt know exact temps. He was shooting my Maxx on a freshly charged pack so the motor was ice cold for the first run or so. I'm thinking about buying a 14T and 18T to try on the gearing to see if it helps.

nbcaz- You dont give up do you? lol.

[MetalMan]

Does your Warrior 9920 get hot? If it doesn't, then that means that you could gear up to make the motor run more efficiently so that it won't get as hot.

[nitrostarter]

Its a BK18120 and I have a PC fan on it. It doesnt get hot from what I can feel, except the 4 capcitors on the end do get warm. I Cant grab the motor tho, it gets hot.

true! my offer is still up if ur interesed!

[coolhandcountry]

What kind of tires are you running as well nitro? That makes a difference as well. I came up your final drive to be 23.5 to 1. If you running second gear.

I wouldn't mess with a 14. I'd go for 18 and 19 for sure. Check for binding. This could be your problem. How old are those gp3300 pretty new?

Cool, he's running bow ties.

I think you right big air. A jump up in gearing may help. Not sure how I missed the tires :o I would just keep an eye on your temps. You may want to invest in a temp gun. They from 20-30 depends on where and kind. Good investment. You can't hold some thing that is 140 f and it is in the safe range. Just a suggestion.

[nitrostarter]

Well I think my slipper is going so I'm think about going to the Strobe slipper. If I use the Strobe, I have to use the 51T spur, so what pinion should I go with then?
I just bought the GP's in July so I dont think its them.
My truck rolls pretty freely.

So you guys think I should go up in gearing? My 18120 stays like cold with the fan on, just the motor could melt an iceberg after a run.

Mike do you carry temp. guns?

[mt_enthusiast]

12/51 will put you about where you are now with 16/66. From the calculations in Serum's spreadsheet with the Maxx Bowties, it is interesting that you were within a couple MPH, 27 versus 30.

[MetalMan]

Try 13-14/51. That should get your speed to where it should be.
