Hey,

I'm researching an Oxy 2 build and I have ordered a Blue Arrow H0988UHS tail servo. Apparently it's programable but looks like it comes set at 1520us/333Hz. Good to leave that as is for an Oxy 2 size heli? It seems pretty fast so should the Rudder Delay be set at 2 to start off?

Going to run the Lynx DS895 on cyclic. The Spirit servo chart shows 1520us/200Hz but Lynx site show 1500us/333Hz. Being that there isn't a 1500us setting in Spirit the pulse will be set to 1520us but should the frequency be 200Hz as the chart states or 333Hz as Lynx site shows?

Similarly, I noticed in the Spirit Servo chart that my KST 565X on my Oxy 4 is listed as 333Hz but the servo specs say 560Hz. Should I be using what's in the Spirit servo chart or the specs I've found online?

Going to order the uSpirit next pay check.

Thanks.

We recommend to use what our Servo list is suggesting.
Servos that are there are also tested and even that their specs are higher, it is not always best to use the highest frequencies. Some servos can work reliably at very high frequencies only for limited time. But it always depend on flight style and other circumstances.
With harder flight load will be higher.

It does not matter whether it is 1500 or 1520 - as it is very close you can set the centering by subtrim. But centering is done usually according the servo arm, so it is only informative value.

Yes, Rudder Delay at 2 can be fine for the beginning.
