Description

The Ripmax SD150 is exactly the same servo as the Dymond D60, and is rated for up to 8.4V operation. This allows it to be used with a 2S LiPo receiver battery without a voltage regulator, reducing cost and increasing reliability - and allowing useful rx battery voltage info to be transmitted back to the pilot when using modern telemetry radios.

The Ripmax SD150, like the D60 is a precision 9 g analogue servo with a good torque and excellent centring. It has a low backlash geartrain and can be used for all control surfaces. Suitable for models weighing up to 2 Kg.

Another benefit of the SD150 (and D60) is the very low operating current. This increases the flight time of the model by about 40% in comparison to a similar digital servo.

Great servo

Great and fairly inexpensive servo to use with 2s lipo batteries. Design is quite old and there are alternatives to those in the market. There is visible slop in the top gears, so wouldn't recommend using in high end models. Comes with handy adapter to install servo flat in a wing.

Nice

Soddisfatto del servo, ma soddisfatto in particolare del SITO che mi sembra molto efficente.
Mi sembra solo che ci siano poche pale di eliche pieghevoli.
Buon lavoro

Don't rely on it for 2.5Kg-cm. Ripmax say 1.5. Otherwise I would give 5 stars. Works well lifting a spring loaded spoiler in a 2.2m electric glider. After removing flanges it is big and flat enough to glue in position.

First time ordering from Hyperflight. Excellent service, arrived next day.
I have used there servos before, and always found them very good.

I have noticed that there are two more reviews on this product that give these little servos 5 stars,I would only award them 1 star Im afraid!
Theres just to much slop and backlash in the gears for me so I can't see how you can set a model up accurately using these servos,whats the point in setting a control surface up to within 2 degrees when the resolution and slop on these servos is so bad?
I have also burnt a few out running them direct from a 2s lipo…I sometimes wonder if they really can cope with 8.4v,Maybe I have had a few bad ones?
Personally I would not fit these into an expensive model ,I would prefer to find an alternative servo regardless of cost.
I will avoid using these at all times but if you decide to use them my advise would be to regulate them or use a smart Lipo @ 5v.

Sorry But Its from my experience.
Jim

HyperFlight comment:
We are very sorry Jim has had such a bad experience. We will look out for geartrain slop, up till now this has not been a problem with this servo.
Regarding failure when running on 2S LiPo batteries, this usually occurs due to a polarity error when plugging the red JST (BEC) plug directly into the receiver, or even into a JST socket. Many of these are quite loose, and allow the plug to be inserted incorrectly.

Excellent servo for the ailerons in basically any DLG. Reasonably light, excellent strength and virtually jitter free.
