Assault 450DFC TT Flybarless Servo question

[rajien2]

Hey guys,

Question Im building my first heli, I have a question about the servos.. Can i just use 4 EMAX ES9256 for both the swash and the tail? or do I need a better tail servo? Also I am still doing research on the flight controler but I am thinking a Kbar any issues with this? Also I come from the multirotor racing world so I have a lot of experience tuning flight controllers but heli is a new and exciting world for me.

Thanks for your help guys

yes i have 4 EMAX ES9256 on all points but i would not suggest it. Because of where the emax wires come out. They can rub the main shaft (mine is a 450L). I had to modify all mine and should have gone with the KST DS215MG to start with. Save yourself the trouble and get the KST you can use 4 but will need a servo adapter for the rudder (i made one)

also the soldering on the emaxx was shoddy

I also dont like the way of the servo wire comming from the back, get the TGY 306 or KST DS215, they are up to the task for the tail, just make sure you put some insulation to the buttom alu case of the servos.

60 amp esc is not needed for that heli, i would recommend 35-40 amp, 60 will be very large to fit nicely in the heli, i have the YEP 40 amp in my 450 and it is more than enough, always warm if not cool as long your setup is correct.

Helis is a whole different world than multirotors, it is dangerous, tunning FBL controller can be tricky especially for a biggener like you because you dont know how it is supposed to feel yet., i would suggest getting a good unit to start out right, i suggest you get Brain or Ikon FBL unit, it has self level function that can help you in the learning process, but you have to solve all your vibration issues first, if you have

Perfect thank's guys I will go with the Ikon FBL and KST DS215MG.

What Kemo said.

BTW yes, if you're new to helis, a recue system on the FBL unit will pay for itself till you learn how to hover and later when learning new stuff.

TGY servos are very good, I have'em all-around on the 450's.

There's Align, Beast X, Eznov Neuron, Ikon, V-bar, Spirit, Microbeast, Naza, Bavarian Demon, ect.

BUT you must sim. the heli to get a feel. Quads are inherently pretty stable, not so helis. Also the unit you mentioned is good, but it seems to be better call it by the brand name and not the generic.

Hey Felix, do you have any slop in your TGYs 306 servos?

[aperseghin]

Both KST 215s and the TGY 306 are good. they are both battle tested and in the same price range. the KST are worth every penny and its easy to replace gears. you will will find people loyal to both, you will find more loyal to KST.

Well, not really. I might have some but it's usually negligible. Kind of hard to tell.
