Flew my T-Rex 450SE with the Spartan gyro and 9650 servo for the first time today. I hoped it would perform like the 611 on my Raptor 90 - it didn't! I get a lot of bounce when commanding a sudden piro, and that's after opmitising the gain etc.

It would seem as if the 9650 is too slow for the 760s default settings. Perhaps I need to detune the acceleration or stop-gain settings using the configuration editor and USB cable.

Anybody had any experience with this combo?

Ideally this excellent gyro needs a fast servo so I will be looking for a 9257 or I'll fit 9257 gears to the 9650. Any other ideas would be great!

Rob.

9650 is indeed slow but it will work if you set it up correctly, you are far from the only person using one with a 9650. about 8-10mm arm i think and you will need to turn the decel slider down and up the stop gains to get the stops nice. what you are talking about sounds like an acceleration thing? sounds like you need the usb cable or buy another servo. i ran a 3153 and 9257 with my 760 on my 450 and it worked perfectly.

cheers

Forget all of those futaba servos for your 450 tail. Go with the JR 3400G and you will wonder why you never used it before. It holds with my Spartan like no other and it is fast and crisp. If you need the file for my settings with my 450v2 with the Spartan and the 3400G servo, just let me know and I can send it too ya. You can do minor tweeks from there. Hope this helps!

Thanks Jay1,

Its great to hear an endorsment of the 3400G which is attractive as it is far more readily available out here than a 9257. The 9257 is much faster but has much less torque. Do you think the higher torque wins out over less speed in the case of the 3400G?

As some will mention, the 3400G is really overkill for our 450's. It is way faster than you will every notice and the extra torqe will always turn that pitch in wind or fast stop piro's. The centering is very precise also. You will love the tail authority with the Spartan and the 3400.
