Apart from cost is there any other reason not to use a higher rated ESC than necessary?
My ENV only needs an 80A for my style of flying, would a 120A be detrimental in any way?

the only thing is the larger ESC normally weighs more.

that is the down side.

personally on these big heli's i prefer to over kill it by a bit and i also run the 120 on my 700.

it just gives you some safe overhead and will allow you to grow into that amount of power with a larger flight envelope or higher output motor, larger blades etc...

Who cares... its just money...

I had a feeling I'd read there were problems associated with having an overrated ESC.

it only increases the amount of current handling.

your power out put will still be wherever it needs to to be for the RPM.

the esc no matter the size will run most efficiently at 100% the only difference is going to come from the motor and gearing.

the castle software will pop warnings about the headspeed being too low to properly govern which is based on the fact that at lower out put say 50% open it is going to be under alot of stress trying to regulate it.

actual amperage numbers should cause no change excluding that having more overhead at your esc may lead to a lower average esc temperature.

obviously your going to destroy an esc that cant handle the current but in almost all things overhead is a good thing.

Who cares... its just money...

Anything I should know before I shell out on a Jive 120? Have there been any problems? Is there a version to avoid?
Thanks

I also was in the same boat as you. For my Rave, I wanted either the Jive 80 or the 120HV, and couldn't decide. I too found that the 80HV would have performed great, but I did end up going with the 120HV. I'm very glad that I did, and there is nothing wrong with it at all. I'm in love with the performance all around.

I believe kontronics is about to release a heli-specific Jive 120 with more programming options and a built in heatsink.

A 700E pulls around the same current as a Trex 550 which comes with a 70 amp ESC.

I go by average current (mah used / minutes flown x 60 / 1000) being under 3/4 of the ESC's rated continuous current.

Having said that I average 30 amps on my 450 with a 35 amp ESC which slightly breaks this rule!

60% of the time, it works every time!
