You guys that are running or have tested the Novak Mongoose. I have a few questions.
How hot does it get especially when you do a lot of braking or reversing?
Does it get hotter with very low (3.8:1) FDR?
I'm thinking of a scenario where I run one in my Tamiya Mini with the silver can 540 and eventually a 25.5 or 21.5 brushless. The gearing is basically fixed at 5.8:1 FDR, so I can't get too crazy there. Novak intends these for 380 sized motors, but the small size and efficiency makes it tempting to look for other uses, just as in VTA.

I'm still running the stock wires but plan to change them for 14 guage. No particular reason other than to customize wire layout. On my chassis I had to lengthen the wires with a splice.
If I had ANY plans to use brushless in our Tamiya Mini class, I wouldn't hesitate to use the Mongoose.

Guys, can I ask your opinion on adjusting timing on the ballistic 25.5 vs. changing the FDR? Is there a benefit one way or the other say increasing timing and raising the FDR vs. reducing timing and lowering the FRD? I was talking w/ someone yesterday about timing and I was curious as to your opinions? What are the pros and cons of doing this each way? Is there a best of both worlds setup here?? I'd like to have good top speed of a loewr FDR w/ decent low rpm punch if possible. Also what temps are you guys shooting for with the ballistic 25.5 after an 8 min. race. I was around 170 after 8 minutes plus about 30 seconds of practice and usually around 155 I think w/ 6 minute mains geared at 3.75 FDR. With my gearing this way I was right in the range of the fast guy s fastest lap times but If I do have to gear down to reduce motor temp I'm sure I won't be. maybe that is where my question about can be applied to this.
Thanks

can someone ask HPI to make a basic premount vta tire..like (5-8 spoke in white)
& will the weight come down in vta from 1550??
just was wondering

I hope the weight does not come down because my HPI Pro 4 is already stripped down to the bones and it weighs in at 1545 grams! If the weight comes down then I will have to take a Dremel and start cutting away at the chassis!

nice looking set of rules..

Well my tc4 is 1555..but i want a tc5 & i know their r really light weight...dats all

the weight isnt that it has to be that exact weight. just that it has to weigh at least that. in many situations a heavy car would perform better than a super light one.
You guys that posted feedback on my questions about the Mongoose, thanks. That was a big help.
