Review by: MarkReliable servo.
Have used these servos for over 2 years. They are great. I’ve used them in 1m and 1.5m scratch built DLG’s on all control surfaces. Also used them on 1.3-1.5m eRES. Reliable, good centering, precise and with ample torque. Light and small with high voltage capability. Would be a good addition if Blue Bird decided to manufacture an all metal gear, high voltage 101. ???
Review by: MarkSuper servo
These are super little servos. I have used many of these servos in various installations: DLG; small power assisted gliders and spoilers on 1.5m E-Res. Great reliable performance for such a small, light servo. A perfect subsitute for Ripmax SD100. Dispatch and packaging is Neils usual exempler. Thanks.
Review by: Brian Rivas
Tiny, precise, powerful, lightning fast: what could be better at this price? Perfect for my yet-to-fly MadRES, where space is a little tight. And thanks again, Neil, for the superb service.

Good servo, like SD100(ripmax),but small size, flight test in progress
Review by: Régis ParetTrès bons produits
Ces servos sont montés dans un F3K. Ils sont légers, puissants, rapides et précis alimentés en 2S.
Leurs petites tailles est un atout pour ceux qui n'ont pas trop de place dans le fuselage.
Je n'ai pas encore testé sur le long terme la météo n'étant pas des plus favorable au vol en ce moment. Ils ont été livrés très vite et bien emballés.

Prompt delivery as always, when they came into stock. Needed a small servo for a project with a small amount of room. Have not used as yet will follow up later.
Comment by: Ole GulbrandsenA fast and strong servo!
The speed on 8v is just amazing. Quite string too, and hardly any slop and good centering. Good value and excellent servo. The power requirement is quite high and more than others, like Ripmax SD100 for example. I've use them for a F3P model on 2S.

Review by: Mark.Superb little servo.
I've bought multiples of these tiny little servos and they are brilliant. I think they represent goid value for money too. Great speed, centering and torque values. Dispatch and delivery 1st class.
Review by: RégisI would recommend this servomoors
Very good product. These servomotors are light little cumbersome and rapids. They seem very solid and have a couple being enough for a glider DLG. very satisfied with my purchase.
Thank you Régis.
Review by: ChrisBlue Bird HV Servo's
Brilliant service from Neil, received the next day and fitted to my Elf Mini, perfect fit and superb quality, as it states centering is spot on.
Review by: DominicMaybe I've bought a worse one
Just bought one and another for normal voltage version. But seems I'm not lucky as this one's centering is very bad. There is about 3 times of shift distance while centering compared to the normal voltage version or D47.
Anyway, I'll buy another one to try again.
Review by: ron ?thatcherBMS101 Hv servo
good smooth free running ,HV servo . Just right for DLG use.
Review by: MarkBought more.
See previous review.
Review by: MarkPrompt service, brilliant servo.
I bought these servos to upgrade my homebuilt "Mimi" DLG from analogue to digital. I'm very impresseed with all aspects of the servo; size, torque values and that the servos will run straight off 2s lipo. Regarding Hyperflight service I am just as impressed. Many thanks.
Review by: Anonymous
Initial impression is great. Very smooth, centers well. I needed the HV capability to run on 2s lipo unregulated.
Review by: AdamExcellent Servo
Excellent little servo. I have used it on my elf, so thank you for the advice. As soon as the battery is connected they centre and there is no play. I wanted to use a 2s lipo without a regulator. I would recommend these.
Review by: ErykGreat value
Fantastic little servo, I use it as a replacement to Dymond D47 (Ripmax SD100) since it's digital and HV. Minimal play. Good precision. I installed 2 of these in a 1.5m DLG and so far they're working well.
