Geez candyman, it's been a while! Still on NiMh I see... That will be the limiting factor for power output here. For reference a good 6s 5000mah pack will be able to push peaks past 3500watts, while 18 NiMh cells will be hard pressed to reach 2500watts.
SH Z-Car, Custom Crawler, 8s Savage, 12s XTM XLB 1/7 buggy, 4wd 4-link rear/IFS Pro4 truck, Custom Hyper 10 Short Course, Belt-Drive Mammoth ST 1/8 truggy, 4s 17.5 MM Pro HPI Blitz
1515, 2.5d all the way, it,s a beast on 6s.
But be very carefull with you MGM 16018, it,s more a 5s controller than a 6s.
It,s rate for 18 eclls NiMh, so 21.6 volts, and a fully charge 6s lipo is 25.2 volts.

The new 16025 Z serie seam to be rated higher on voltage.
