Default TREX 450 Pro V2 ESC question

I have been flying planes and specially heli's for years now, but nitro only.

I am quite keen to have a go at electric out of curiousity and I have just bough a TREX 450 Pro V2 (Flybarred)

Almost embarrased to sat that I know very little about LiPO's ESC's , all those numbers on th engine, KV rating etc. etc. But I have been reading and asking questions and have a fairly good grasp of it all now.

Only one question specific to the ESC that you get with the kit. It is a RCE-BL35P speed controller.

This esc has a governor funtionality. In the manual they state that in order to use it (Only in Idle up) , you have to select Helicopter 2 on the ESC and then set your throttle between 75% and 80% ... What does that mean? Am I correct in assuming that you then have a flat throttle curve that looks like this 75-75-75-75-75 for instance and not use a 100-75-100 throttle curve? And is the esc then clever enough to know when you are flying in normal mode and then switch to idle up?

Take this fwiw, but I've never seen gov mode in a heli esc work worth a damn on anything other than a really good (kontronic or Castle) ESC, on the cheaper ones they just pulse the tail and drive the gyro batty.

If it were my machine, I'd setup a throttle curve and call it good.

Hi

I don't plan on using it as a governor. Just curious if I understood the concept correctly.

But I am not much of a fan of governors. Maybe I am old school. I have tried the Align and the TT governors for a while but was not that impressed by them. No disrespect, I am sure they do their job well.

Granted, it takes a bit longer to set up a heli when not using a governor, but once set and it's right, I can't say I really notice the difference in my style of flying which limited to light 3D and smooth aerobatics

They work great for nitro, especially the MultiGov but I've never used them for electrics except for my scaler and thats got a high dollar Castle in it.

But yes, you understand it, set your throttle curve straight across for an ESC in governor mode
