This one is a very nice servo! It came sealed in a small sized package, containing the servo and 3 different types of arms.

From the outer side it seems to be of really good quality. The only negative aspect that I found is about those little bit fragile wires. I would recommend you to handle them carefuly when mounting the servo and protect the connecting point to the servo with some tape.

I decided to test the servo before placing it into my F9F Panther, which I bought at the German warehouse 2 weeks ago. I don't trust those cheap servos coming with the most foamies, so I replace them before maiden. This servo is beeing used for the elevator of my F9F and it works absolutely awesome for about 17 flights, now!

I can really recommend it and will also place some more in my other foamies and, of course, in those which I will get in the future...LOL. Give it a try and have fun!

Bought 3 of these for cyclic of my EXI 450 heli. Havent finished the build yet so I cannot comment on function...but fit is perfect once you remove the gussets from the top of the mount (if you mount them inside the frame the gussets wont allow for a flush fit).

Ordered 3 of these for a TREX 450 clone. Fit and finish seem nice but havent finished the build yet to see how well they perform.



For anyone wanting to mount these inside of the frame of your heli...you will have to use a dremmel to remove the gussets on the top side of the mount tabs. Otherwise, they fit a 450 frame perfectly!

Pretty fast Servo. And it is strong and not so expensive. I use it in a glider and there it works fine.

I have purchased 8 of the servo's mounting them into two airplanes. I find them to have accurate centering and more than enough torque for 3D models up to 40 ounces. The first four have been in use for over a year and work with no issue's! I like the performance of this servo my airplanes feel more crisp and responsive than with more costly servo's. They are mounted in the Mini Funtana X and a 10-200 Ultimate Biplane.

Very good servo for the price. Now you don't have to look anywhere else. Just order it from here- very cheaply.
