Worked great for my ant weight combat robot! No issues

I didn't end up being able to use this servo but I was impressed by its build quality, the beautiful aluminum 25T servo horn, and the mass of assortment of accessories that came with it. one of the more solid feeling products I have ever handled I'm sure it would have been brilliant if had fit my application...

No pushroad connected at all, yet if I move the transmitter stick quickly, the servo fails to update position. I can only make it move if I carefully move the transmitter stick very slowly, if I gets "stuck" I have to move the stick back to the servo's position and slowly "lead" it to the new position.Completely unusable, and absurdly slow even when it does move.When it's stuck out of position I can hear it making faint half hearted attempts to move - seems like there's a design error in the "digital" servo amp such that when the error between the commanded position and the servo position is too large, it chokes on the difference, rather than simply doing its best to close the position error at whatever rate it actually can accomplish.Too bad as I could have almost tolerated the slow movement - wanted to use this for the sails on a small 20 inch RC sailboat, but the way it won't respond to a rapid position change is unworkable.

I bought this to replace the stirring servo on my HPI Savage RC Monster truck because of the high torque capability. Got the servo, took it apart and was impressed with design with metal gear configuration. After installing, I was disappointed as it would freeze up with quick rotation changes causing my truck to crash. Wrote the seller and agreed that it was low voltage problem as I was using rechargeable AA 4 cell that had only 1.2v x4 (common with rechargeables). I purchased 1.6v Nicm batteries with 1.6V per and it made all the difference. Strong servo with quick reactions. Great price on the part , happy with purchase.

This servo is strong enough to delete the second servo on my old Traxxas Revo 2.5r truck! I found that replacing the stock servos with just one of these, the steering response is much faster and its got way more torque than the stock cheapo plastic servos that the truck came with.Only problem in doing this, and I can't say if it was my equipment being faulty or just not compatible with this servo, was that the Traxxas receiver would only control one servo, it would not control the throttle servo any more. Put the old servos back in the rx and all was working again (albeit, stripped for the steering, which is why I replaced it in the first place!).Rather than downgrade to replacement servos from Traxxas, I just decided to buy a whole new radio system (see my other review on the Flysky FS-GT3B radio), bought another one of these servos for throttle, and with everything installed, the Revo is working better than it did when it was new!Time will tell on how long these servos will last, but for now it works just fine! If they do give any problems, I'll update my review.

It's much stronger than the arrma servo it replaced but it's a very slow servo

It's not bad. My beliefs are it is not as powerful as it says but for the price... satisfied

EPオフロード車にて、サンワ製の送受信機とアンプにつなげて使用しました。なんの問題もなくしっかり動作しています。プロポに付属の純正サーボより安くて、さらにメタルサーボでこの性能なのでコスパに優れると思います。

SANWAのSRM102と比べてスピードは少し遅い感じですがトルクは格段にあり、サーボホーン側からは軸は動きません。コスパのいい商品だと思います。耐久性や耐水性はまだわかりません。。

タミヤ ダンシングライダー用に購入しました。使っているESCが５V１ABEC出力でしたので、ESC経由の電源供給ではかなり性能をスポイルされてしまっていました。サーボ配線の＋コードをバッテリー直結として７．４V印加可能としたら、本来の性能を発揮してくれるようになりました。説明にあるように７．４V供給はMUSTかもです。正規電圧で駆動させると見違える動きを見せてくれます。まだ使用期間が短いので耐久性が未知数ですが、とにかく使ってみたいと思っています。EPオフロードのSCトラックや４WDのステアリングサーボなんかに使うと良いかもです。価格的にはかなり魅力的なので、機会があれば、もう１，２個買ってみたいと思っています。

早速、取り付け、机上での操作を行いました。なかなかのトルクで前輪が動作し問題なさそうでした。後は実走して感触を確かめたいと思います。ちなみに、車はGPサベージです。
