Chad,
Thanks for your input. I just got confirmation from Plettenberg that the Terminator can be run safely on 14S with bursts of just a few seconds to 120 AMPS. That could yield 6300+ watts which should be gobs of power. The interest in the 14S is to allow the use of my stash of 5S 5000 packs. Add a 4S in series and I have upped my battery power by 40% and the 88" Yak is about the same percentage heavier than my 74" Yak so I am hoping for similar flight times. The downside of the 14S is the smaller prop, about 22" but then I believe that is about what is used on the DA. Let me know what you think of my idea, I am just in the planning stages at this time.
Thanks,
James |

Hi James
If Pletty said 14s was acceptable then go for it! I do know guys have pushed that motor to 6kW, and it can probably do more as long as its not getting hot. I have ran the Evo to 4kW and its a much smaller motor.
I would try and keep as much diameter as possible on the prop, and reduce the pitch to keep your peak amps reasonable. With the higher voltage you will have lots of rpm, so you should be able to get away with less pitch than what someone running a 12s setup would have (12" usually). Probably a 22x12 would be a good start point...you are have about 35-40% more rpm than an Evo so based on that I would guess you will be in the 110-115A range on that prop with 14s. Then maybe try a 24x10 and see if you could run that, you might find you still have lots of available speed, but better pull out of it.
