i had a 9252 on my collective also. seemed ok till i put 2 9252s on the collective then i noticed the difference. it was real mushy with 1 on it. maybe not enough torque. if i do it again then ill go with more power and one servo as my 2 servos are hard to set up.

maybe im not saying this right but i was looking for someones help who has a raptor 90 and to what servo they are running on collective for a raptor 90

i have these same servos all around on my tempest and are great ...but the raptor 90 isnt ccpm theres only one servo for collective and i think the 9252 cant haddle it....

anybody with a raptor 90 tell me what is the best FUTABA servo to run on a raptor 90 and i run duralites with a 5.1 regulator so i need to stay at that...thx in advance mike

I use the S9151 and works fine, but not fast enough for piroflips, i consitter the S9451, strong and fast.

I have been running the ko 2123 servo at full duralite voltage (no reg for that servo)

I dont see why the 9252 is not working though... is the collective linkage and head free from binding?

Also, do not run the linkage on the servo way out on the arm, I have found that setting it up to give you 100% atv is much more efficient on the servo.

Maybe move your servo horn ball in some and increase your pitch atv to maximum, this will unload the servo a little ,and reduce your speed a squeeze.

JR DS8231on collective and cyclic. 88 in oz and .22 sec. Plenty of power and speed, piro flips, collective pumps etc..

I agree with Don, how far out are you running the collective rod on the servo?

the 9350 works just fine on 5.1 volts.


It would be a good choice.

I use a JR 8311 on my raptor 90 I know it is not a futaba but maybe you can find something with similar specs . It works great and no lag or anyproblems with it. Specs are 130 tor and .18 on speed at 4.8 v.

9350 servo is fine.
Maybe if you could do a push-pull system like the Freya x-spec, it would improve the response. I'm surprised TT didn't do it as an upgrade. I have a 9151 on my R80 on 4.8v and it's good, but not as good as an e-ccpm setup.
