basic 4200+8 cells +stadium truck=nice

[Gustav]

Got a package from Mike this week (cheers fella!)which included a basic 4200 and some GP2200s and so far i love this little motor,running it on 8 gp2200s in my MF2,it looks really nice too,great quality,i didn't realise how tiny they were either.

Built 8 cell packs last night,ran this morning,tore the middle out of the diff gear within 2 or 3 mins(may have been slipping)

Tried again at lunch time with good results:

Running for 8 mins with 21/86 gearing:
GPS says 39.2 MPH,18.97kw was clap cold (85F),motor was 130F,batts were a little warm(didn't measure)

This was the the first charge of new cells and same charge as when i tore the diff gear so i'm happy with the run time.

My thoughts are that this is a nice speed to gear to for this setup,i was wondering how high you think i might be able to gear to considering the esc is running so cool,maybe it's just understressed in this application?

I'll try gearing up and down a couple of teeth to see which way the motor temp falls,waiting for bigger pinions so i'll report back later.
