3 cell for e-flite Park 250

Why is 3-cell recommended for e-flite Park 180, but only 2-cell recommended for the Park 250?? Both are 2200kV, and the Park 180 is rated at 2.6 Amps continuous compared to 7A continuous for the Park 250. I'm confused.

I certainly ran the E-flite 250 that I tested on 3s voltage (six different props from 4x2.5 up to 5x3)... it did very well at up to 6.85A/74W. I cannot imagine how small a prop you'd need on a Park 180 on 3s if you didn't want to exceed 2.6A!

Dr Kiwi,

I wanted to run something like a 4x3 or 4x4 on a scaled down profile jet for indoor flight, and from my guesstimation, the Park 250 looked ideal. You've confirmed my expectations.

Thanks,
Harrow.

Thanks!!!!!!

Even with a 4x2.5, prop speed is 72km/hr. Can't wait for the next indoor night, this is going to be a blast!!
