Gohbee Aviation Stinger 30-90 > Servos for Gohbee 90?

I am trying to get my new Gohbee 90 size helicopter going it is alot like the raptor 90 just a different name with lots of upgrades. I am just wondering what kind of servo's should I put on it besides tail servo? I have a hawk pro 30 and I just put standard servos in it and work fine. But I am aware this is a bit bigger so what would you recommend? I also am probably going to put a gy401 in it with the tail servo combo. But I need to know what other servos I should use? I also am planning on doing 3d with it probably or trying soon. Please tell me what I can use with 3d and not with 3d maybe thanks again.

Also if this isn't in right topic or part of the forum please move it I couldn't find a topic better think this is right one.

I would go with a servo rated at 90inoz and .15 speed or better, I dont know what kind of radio system you have but they would be a safe bet. Also the 401 9254 gyro conbo is okay for normal flying and mild 3D, I would go with the 611 or better if your gonna puond it hard. The tail will hold better. I run 8611jr on the controls and the 611 on the rudder. I use the regulator from Fromeco (Arizona reg) to limit the gyro volts and run all other servos on 6.1 You will like the heli, Dave puts out great product.

On all of my helies I am slowly changing over to the HiTec HS6965 servos for everything including rudder and throttle. The 6965's can be run in digital servo mode for both the tail and gov if your gov supports it, and are also perfectly happy with 6V.

The 401 has never had a problem with 6V, it has always been a problem with the 9254/9253 servos.

Think these would work http://www.horizonhobby.com/Product...?ProdID=JRPS821 good even for 3d? My dad says we probably should get one with 110ou so not good or what? I would like to maybe get a DX7 and they come with these so do I need to get different ones?

I run the specktrum on my helis also, I would NOT run those servos. They are not rated for the 90 size ship. I used them in my 30 size. The Hitecs mentioned above by Jeff are awsome. I prefer futaba servos, but have used many Hitecs.

Im kind of on a budget and the high tech servos and most with those high of specs that I find are like $79.99 a peice. Is there any other cheaper ones that will work lol? Will one that come with DX7 work because I might get them?

I didn't know you could use 90 size and budget in the same sentence, haha. You might look at the bluebird 821 servos. Give David at Gohbee a call and get his thoughts. You can check them out on the Gohbee website. They are $68.20, a little cheaper than the hitecs.

I have not yet tried the bluebird servos but Gohbee has done a bunch of testing of them and they seem to like them and have not yet had any problems.
Call David and talk to him about them. 800-381-4127.

I am looking at getting these maybe http://www.servocity.com/html/s3305...al_gear_bb.html they have 99oz torque and 0.25 at 4.8v and 0.20 at 6v and they are way cheaper will these work sound like they will for all but tail? My dad bought some and used them on a big bi plane and they are working fine this bi plane ways like over 30 pounds. Think they will work or do I need better I really want them to do 3D but really I haven't ever done 3D yet in real life but want to soon but probably wont lol.

Those would work fine for learning to fly up through forward flight, loops and rolls, .2 speed is way slow for 3D.
I would recommend a minimum of .15 speed, faster is noticeably better.
Those slow servos on a 30 lb plank are more than fast enough but will cause problems on a heli doing 3D.

If budget is a real problem, I would start with a fast powerful servo on the pitch, and you can get by for a while with slower ones on the cyclic, and upgrade them latter. Then sell the slow ones to your dad for his planks.

Jeff....

Would you want a servo on the throttle that is just a little faster than the pitch servo .....so it could deliver the power before the demand...?

I do prefer a fast throttle servo for the reasons you describe.
There has been a huge amount of discussion on this subject.
You can while under the constraints of a budget get away with a little bit slower and play some games with the linkages to regain some of the speed needed.
By reducing the available steps with a long servo arm and reduced ATV/end points, the throttle is not as adversely affected as the flight controls would be since a carburetor is not a real precise thing in the first place.

These servos can run at 0.20 or so with 6v would that work? I also have a Hawk Pro 30 size and it's controls are pretty fast for me since I am learning and my dad said they are like 40 oz in lol and the throttle server is crappy he says you can use whatever on throttle but I just seen the above post. Were it would help to have better one because it would give power faster that maybe why sometimes when im up high and come down or it comes down due to wind etc it takes to long to pull out like 5 foot before it stops falling probably alot less but awhile.

I got my eye on some servos that are the ones you told me about we will see. But I may get them or I might get other's not sure yet.

I run a cs 12 (same as hs 81) on the throttle (.11 transit time) with a s9252 on the cylic (.15 transit time).

Couple that with the multigov and the engine is always ahead of the collective.

Hobbico cs 12
http://www2.towerhobbies.com/cgi-bi...?&I=LXPB32&P=ML

or HS 81
http://www2.towerhobbies.com/cgi-bi...?&I=LXN676&P=ML

Same exact servo except hobbico puts there name on it

I didn't clarify that my heli is the gohbee stinger 50 not the 90. A slightly higher torque servo might be necesary for the 90's collective. As for the throttle, i would imagen those micros could pull any throttle you ask them to.
