I'm super pumped to get back into the heli hobby after 8yrs and I'm new to electric motors. I started in 94' with a Cricket! I though i spent enough thousands $ replacing all my old equipment last week from my nitro xcell fury's/Raptor that are in the garage with 2mm of dust to get a fresh start. However, after deciding on a new SAB 700 black thunder kit, 12s batt, Ikon2, scorpion 4035-530, new Switch blades, lipo charger, Spectrum DX9, receiver..... I JUST FOUND OUT ALL MY FUTABA 9254 AND JR HIGH TORQUE SERVOS that are new WONT WORK 4.8V TO 6V ONLY

Can someone please advise me on some good 700 class servos, not the most expensive ones, but solid good ones. I don't do crazy 3D stick jamming flights. I've narrowed it down to KSTX20-COMBO of 3cyc and 1 tail for $479 from Amain hobbies. Do I really need servos this expensive? BK's, MKS, ProTeck RC??? I'm stuck on page 15 of the build because i didn't think i needed new servos.

Why not use a good quality regulator / BEC from somewhere like Western Robotics or Perfect Regulators ?

ProModeler
Though I haven't used them yet, I've heard good reports about ProModeler servos. Might be worth checking out. http://www.promodeler.com/

Western Robotics
If you go the regulator route for your 4.8v and 6v servos, check out Western Robotics, as stated above. I put a Hercules Linear Battery Eliminator in an old X-Cell SE99 that has Futaba s9252 servos and a GY601 gyro with s9251 servo. All are rated for 4.8v. The Hercules works great on a 2s LiFe pack. Output voltage is set to 5.4v. http://www.western-robotics.com/WRL-HBECLE

Another vote for a Western Robotics BEC. Here is one for sale right now https://rc.runryder.com/t823266p1/ about half off a new one!

Start with what you have and upgrade as you need to.

If I wanted new servos on a medium budget id go
Kst 525 on tail. Love this servo
Promodler 360 on cyclic. Again promodler are great. He's been in the heli world a long time and knows his stuff

I'm not really shopping for servos but I love the discussion. I've always got my ear to the ground for well liked products.

Which ProModers are you guys using and recommending? I see they have a tiered type approach. In a standard sized servo they offer 3-pole, coreless, and brushless servos with choices of torque specification within each categorize. Prices for their standard sized servos seem to range from $39 for a.17/130oz*in 3-Pole servo to $100 for a .05/345oz*in brushless servo. Those that are using them and like them, which servos are you using?

It would also help to know what they are installed in and what FBL controller you are using (if you're using one at all). A servo installed in a flybared Raptor 30 may perform differently in a 700 class FBL heli.

Not brushless but the Savox SC-1267SG will do the job nicely without breaking the bank.

You should look at the Protek 270 cyclic and tail servos. They are Xpert R2s rebranded for the Protek name. I've watched Jason Bell beat them hard at various meets, and they are good mid price servos.

Thanks everyone for the great feedback!
So I dropped big bucks and got some sweet new Servos. Everything is top notch and new on this beautiful ship so I didn’t want to skimp on a important final detail. I’m way over budget regardless. I will keep you all informed on my first electric hover! I got all 4 Servos for $400 because they have made so much $ from me in the last 2 weeks

Unfortunately, good servos are going to not be inexpensive by nature. I've watched Jason fly really hard on a Logo 700 with those servos, and they didn't miss a beat, so I really hope that they work well for you.

I much prefer tried and tested servos from long standing reputable brands like Futaba. I will buy cheaper servos but won't put them in anything fancy till I'm confident with them or run them at lower voltages.

Thanks for the heads up.
Those promodeller servos look very tempting. I am looking at replacing my align servos in both a 600 & 500

spending time, paying attention
