[swiftneed]

Seems like we are shooting for the 2000kv which is the 1512 2.5df neu i am wondering geared properly the amount of run time on ib 4200. Glassdoctor i meant the 1515 1yf i believe but luckily u guys r here for the help, I could see myself not matching up correctly what i would like, thanks so much for all the explanations thanks to jHautz for putting it in laymens terms, OH and by the way i let the smoke out on the shulze 18.61 experimenting on how to get this running the c50 was a rocket cool:007: :005: Squee did warn me :025:
