produit reu diffrent du produit affich. Les couleurs des 3 fils est habituelle sur la photo du "catalogue" : NRB pour gnd/plus/signal. Ce que j'ai reu (et pour la deuxime fois) pose problme : rpartition R/N/Clair qui devrait, je dis devrait, correspondre plus/gnd au centre/ et signal oppos plus. totalement inhabituel donc. Que faut il faire comme rpartition des fils et des couleurs de fils pour tre sur de ne rien griller?

I found it fine with Orange RX415 Micro receiver, but mine required servo's wires to be swapped around at the plug. It was supplied incorrectly wired for use with RX415. Wires should be white, red, black instead of red, black, white. If you are carefull the plug's metal pins, to which the wires are attached can be removed and reinserted in the correct order. Perhaps the servo is intended for use with something other than the RX415.

These are pretty good quality and lightweight
but the downside to this type of servo is that
it slides forward and back rather than rotating
on an axis like standard servos, so you dont
have as much travel for control surfaces. Like
You would with a standard servo.

One thing I don't get is why there is 3 "Adjusting" holes
on the horn they don't speed up or slow down the speed
they just raise and lower the control rod which is also pointless.

This servo worked fine with a 2s but sometimes if you move
you're stick from lock to lock really fast the servo tends to
not be able to align correctly and stutters back and forth really quickly.

Carefull: This item does not work with AR6400/AR6410. I Tested it with an adapter (different plug and swap /-)

I wouldn't call these things fast (on 4.3V), they're rather slow compared to other servos in this weight class, especially the non-linear ones. I bought two to build into the wings of a 40cm wingspan freeflight -> r/c conversion but these things simply don't have enough throw to move the ailerons enough for my needs. The holes for the linkages are huge, I'd like 0.5mm but these are at least 0.8 if not even 1.0mm. That forces you to use rediculous linkage dimensions to not get a gap which is fatal with the tiny amount of throw these have. Worth mentioning is that the connectors are not wired to fit the OrangeRX R415 receiver unless modified.

this is not small at all... this is abnormally tiny! its insane, its quick but not very strong (2grams servo it not for a big plane so... ) I don't feel really safe to hold it... its so small but kinda sturdy! get one and test! I did and I'm happy with it! :D
