HITEC D-951TW vs HSB-9380TH servo

So, considering servos for a new 35% airplane.

Differences between the D-951TW and HSB-9380TH servos?
Specifications appear similar.

Will be run on 2 cell LiPo power. Interested in differences in longevity, precision, centering, and battery consumption....

Thanks for any assistance.

The 9380s are brushless... and in my opinion, have no equal for "longevity, precision, centering, and battery consumption" et al.

+1
9380 is one fine servo, best I've ever used. I don't know anything about the other servo.

The 9380TH is an awesome servo, very low amp draw, great centering, fast and instant .

Thank you for all of the input. The D-951 had been suggested, but I am going with the 9380s.

What do you guys recommend for a programmer? I see the DPC-11 listed as being able to program all current HITEC servos. I like that idea. Anyone have any experience with that?

Regards,

Tim

Yeah, no, Tim, definitely not on the Hitec programmers that use your PC. They are a novelty, but they are more time consuming and routinely change the settings you're not working on. The HFP-30 is definitely the fastest, easiest, most fool proof, programmer.

The DPC-11 is more for the surface guys or robotics, for airplanes you will want the HFP-30. It has a unique sync function that allows you to sync 2 servos to each other- perfect for matching aileron servos together.

The case, and the price, that's it.

Some prefer aluminum case, some prefer plastic case.

ok thanks. Just checking since I bought a gaggle of 950's last year to replace some JR servo's.
I've been using the DPC-11 connected to the computer in my garage, so its not a biggie to use it, but that standalone programmer is nice. Will have to pick one up since I am running 950's and 9380's now.

Years ago I had a plane with the 7955's and with IMAC I didn't like how I had to retrim the plane almost every flight. It seemed like I had to adjust a click or two (radio setting was 1 for finest adjustment). I switched out to JR 8711's and every throw was matched up perfectly to not adjust anything. This was an experiment and it was worth every penny. It took care of the trim issue I had but the other side effect was my flying control improved. I was not expecting that. In fact a person at the field noticed the better control I had with precision. The 7955s are a good servo but the 8711seemed better for me with IMAC. This was quite a few years ago. Fast forward to late this year. I set up my H9 Sukhoi with 950's and 955's. Good servo but I noticed the trim issue again with this plane. I was 4 weeks out from finals that i was trying to attend and this was a new setup for this plane and it was unflown all year. I played with it and played with it and just didn't have the same "feel" as I remembered it having the last time Ingles it for IMAC (2016). So I bought some JR 8911's and reset up the plane. It felt just like I remembered. Flew much better for precision and didn't have the trim issue. The 950/55 seems like a great servo and I am keeping them in some of my planes but for IMAC, I am sticking with JR.

The D950 and D955 are infinitely better than the original 7950 and 7955. They have the highest resolution available for servos and have the highest refresh rate for centering (350hz). No other servo can match what the DSeries performs on the market, aside from the Hitec Brushless line.

Pilots like Andrew Jesky have confirmed that the D950 and D955 are ultra precise and are infinitely better than the old tech. Every pilot I have sold them to that runs them in IMAC and freestyle has commented that their aircraft flies better and more precise than ever. Why someone would say their airplane doesn't track as true is beyond me, especially when using a 10+ year old servo design instead, because the DSeries servos are better than mostly anything out there. Most likely this is a problem either with their radio system or the setup of the airplane.
