Is it fine to use 9252's on the cyclic and a 9254 on the tail if I'm going flybarless or should I use something with more power? Thanks,
Mike

I'd say the 9252 a little on the weak side for FBL on a big heli - BLS 351 or 451 would be better - the 9254 should be OK for the tail - if you're gonna do mainly AP and sport flight they'd probably be OK but if you're gonna get a bit more energetic some mroe recent stuff would be better - I havae a BLSS 254 on my tail - seems OK.

This is more dependend from the CG of the blade than from flybar or flybarless.
But what you should more look for is the linkage between swash and blade grip arm. Note that now the double force is going thru the ball joint. So I have choosen for Joker 3 the fat joints. With the standard joints we had a crash with a cracked joint at 129 mph. This is simply too much for the small joints. Note that you have two of them on a flybar machine (=half force).

I remember when Jason Krause used to abuse a MA Fury 90 with 9252 servos on the cyclic...can it be done...yes.

Though with such a high end kit Id consider at least BLS451 servos.

I am about to order the same servo combinationn for a just ordered Joker 3DD. How is this combo? I will be using the BeastX flybarless controller because Gerd told me that it works perfectly and is very easy to setup.

Those servos work great. Strong, responsive and piece of mind.

I forgot to mention that I am running the BLS252 at 6.0V. You get 175 oz-in. of torque at 6.0V vs 139 oz-in. at 4.8V.

If I was going to run the cyclic servos at 4.8V I would go with the BLS351.
