Matt,
The normal S1 Ringmaster setup is something like a BadAss 2320 860Kv motor, 4S 2200 Thunder Power pack, 10x5.5 APCE prop (I use the pusher on mine) set at 9850 - 9950 rpm, on 60' center to center lines, lap time around 4.65 sec. For the OTS pattern a weight of 34 oz ish will work, for the PA pattern you need to be below 30oz.
I have used the BadAss 2320 860Kv with a 5S 1600 mah Hobby on a 9 1/2" x 7 APCE-P (cut down from 10" and heat pitched up to 7 at 70% station) set at 9650 rpm, this give 4.6 sec lap time on 60' C to C lines for the OTS pattern run time is 4min 40sec has 15 -19% left in pack. This pack fits in the nose in the Ringmaster where the IC tank would go as it is only 70 ish mm (2 3/4") long.
Best, DennisT
