Everything worked out with seller. I had the 50 amp esc you have and it shelled out. Sorry about drive parts. Put that new motor on on 3S. higher amp esc. What size esc do you have in the other boat. 2900kv x 11.1 = 32190rpm.WOW, bring a change of pants along in case of fallout,LOL! You'll find out the sharp turns need caution for spin-outs. Congrats!!! You're getting to know boating pretty good, video when you can will be fine. Prop for it is a tough call. Being you've got a high rpm on 11.1, i'look at Offshoreelectrics props in the carbon fiber section, Find the correct rotation props and i'd say a 633 which is a 6 pitch. Higher the rpm, lower the mm size by 1 or 2mm like going to 435. Now a higher pitch has a force cone which is small while a lower pitch has a bigger force cone and disperses the force over a wider area. I'll look up Offshore.Lookup carbon s series- 2327.33 which is a 6 pitch and see how that works out for controlability of boat with the high rpm status. They seem to workout real well for me. I just ordered a 2370 bl (brushless) from Kershaw motors and will run on 3S with rpm at 26307. Spare>-I checked on my Arpro 1 prop and i have a y535 metal prop on 3S and located in props at Offshore in y series section.
