Hello :-) This is a genuine independant review. I bought a dozen of these servos because I have the ptk 9497 type and they work well - so I trust this manufacturer to do a good job. My trust and faith in this brand is growing day by day. Now, onto my brief review. Bangoods' packaging was excellent, the servo came in anti-static bag with display card, inside, the servo & another clip-lok bag with the 3 arms and screws. All of that was wrapped in epp foam. The PTK 7452 servo is better than the average digital mg servo in my opinion. The servo is strong, strong enough for any of my models, including the gliders. PTK make another almost identical servo with twice the power at a similar price - (maybe a dollar more), but these are still adequate for what I want to do. This model '7452 centres well every time regardless of input voltage as shown in the photographs below. I want to compliment bangood and the manufacturer on a great piece of engineering.

bon produit pour le vol classique.
