The Goteck range of digital high torque low profile car servos are up there amongst some of the best for quality and reliability at a price that offers excellent value for money. The top and bottom cases are made from a high strength fiber reinforced nylon and the center case is CNC machined from solid 6061 aluminum, this acts as a very good heatsink for the motor and amplifier.
The BL1511S offers a metal geared, low profile digital servo with a brushless motor that has excellent torque and incredible speed. Primarily designed as a car servo due to its low profile but it will be equally at home in all other types of models.

Good quality servo. Use it as a retract servo for my Hyperion Hayate 40e size plane. Setup burnt a lower end servo previously. This servo handles the load well. But it got pretty hot. Hope it holds for maiden.I ordered only one servo and tested in terms of speed. It is very good! My only problem is that the servo horn simply did not fit! It was impossible to assemble! Any other servo horn was ok except the included one... Have you met this problem? Strange that the product picture also shows unfinished inner part of the horn...Ottimo servocomando molto veloce 0,07 secondi e potente 12 Kg considerando che si tratta di un servocomando a basso profilo. inoltre estremamente leggero 45 gr ingranaggi in metallo e cassa mista plastica metallo. ottimo rapporto qualit prezzo pu essere tranquillamente paragonato a servocomandi di prezzo decisamente superiore. consigliatissimo.I use this servo on my trooper and it works great, fast. I opened the bottom plate to make sure it has seal or not and yes it has rubber seal on the bottom plate and also on the screws. So I think this servo is also waterproofed.Centering problem. Good price for a brushlessI got three of these to try out. 1 for my Xray X1 and 2 for my NT1. I installed the F1 servo and it was TERRIBLE. It was non responsive to sub trim adjustments and would jump to position after 30 or so sub trim steps. Then once on track it would never return to the same center position. This caused the car to wonder aimlessly. I didn't even bother opening the other 2 servos up. I'm returning all. Of course I could have just got a bad one to start off with but it's just not worth the trouble. Much better / proven servo for just a bit more money on the market.Very responsive servo. I have 2, using one for steering in my electric 1/10th tourer and throttle/brakes servo on 1/10th nitro tourer.
Current draw is quite high. It causes 3 times the voltage droop compared to the full size KO Propo steering servo in the same model.
Still great value for the money.
