Hey all,

Going to finally order the servos for my YS91 powered X-spec and was wondering if any one sees anything wrong with these?

Collective - 9151
Cyclic - 9252
Throttle 9253
Gyro/tail - 401/9254

Trusting your experiance.

Thanks!!!

There, their and they're. It's really that simple.

If your going all digital on the servos, you might as well go for a GY601/9251 instead of the GY401/9254. It's only $100.00 more and you will be getting the best gyro instead of an OK one. Everything else you've chosen, looks great.

Take Care,
Cheers, Patrick

With all the digi servos, you prob want to look into the lipos, Or you will be charging like every 2-3 flights, 4 if your lucky. Especially if you are going with the gy601. And this way if you get a gv1 with know problem. I ended up getting a duralite pack. I could have gotten a much cheaper battery pack but i like there safety circuitry.

That 9350 is a fantastic servo. Very fast and strong. Got one in my X-Spec.

--------So that's what this switch is for!!!

Kinda got the impression from Futaba's site that the 9350 is a 6 volt servo? No?

You can use the 9350 servo with either 6V or 4.8V. On the servo box it says the speed and torque of both voltages. It's just faster and more torque with the 6V and it's really meant to be used on R/C cars and they use 6V. Lot's of people use the 9350 servo on their helicopters with 4.8V.

Take Care,
Cheers, Patrick

9350

Gotta say I like it. I was flying the jr 8311. Great servo but I do like the 9350 better! Try it out!

That setup is fine, i had it with a 601 rather then a 401, with an 2700 Mah 4.8V Nimh pack - could get 5-6 flights easily, no problem at all.
the Duralites are way better though ! Way better !

@ade

When you`re flying the helicopter really hard and the current becomes larger (like 5A) and the battery isn`t fully charged anymore the voltage could drop....really... I had a batterymonitor on my R50 when I was flying with a 4NC Sanyo RC-2400 battery and I could do 2/3 flights of hard 3D and then the voltage would drop to much in flight...(the batterymonitor remembered the lowest voltage)
Most of the time it only took 1000mah out of the battery and when tested it was oke.

I didn`t like that so I installed more cells and a regulator... on a 90 I think the Duralite system is highly recommend

Good luck.. and now back on topic

Cheers,

Rich


ps. I have 4x 9252, GY401/9253 and a GV-1 on my R50V2.

9253 is overkill on throttle, a 9203 or 9205 (fast analog) would be better if you have one laying around left over from the old days.

Here I go again, get a servo isolator from http://www.i4cproducts.com which will allow a separate battery or 2 batteries (4.8 or 6V) to run the servos and a separate 4.8 battery for the receiver. With the big digitals sucking down the voltatge, this device is a big plus.

with the 2700 nimh pack I was getting 3 flights with all digitals and 601.
I use a 6v. servo for collective with a 4.8v pac and it more than enough.

I would get NiCd or Duralites, if you havent bought a RX pack already.
Sorry for the thread hi-jacking.

'Hm now I just have to find out where to connect the GV1 sensor to the Jazz80 ESC.

Thanks!

Thanks for all the great replys. Servos and gyro on the way. Decided to stay with the 401. Reason? I'm 46 years old. I don't see myself going backwards at 60mph doing 4 point rolls six foot off the ground any time soon, if ever. For the type of flying on plan on doing, I think the 401 will work just fine. If my flying skills develope to such a level that I can make use of the 601 then you bet, I'll upgrade. Also, I WILL be running a duralite 4000mah pack on this bird. Electron flow is like headspeed. Without it, your screwed!

Looks like it's gonna be a nice day to fly. That would make it the twelfth one this year. Geeze I like Iowa weather............

Thanks again!
