This upgraded version of the tilt mechanism features injection moulded pieces made from black fiberglass reinforced nylon parts. All parts were forged in the fires of Mt. Doom, making it almost indestructible. (It’s the same plastic used by high-end propeller manufacturers.)
This tilt mechanism is designed to be as simple, precise, light (only 10.6g), durable and with as little air resistance as possible. All parts are made from black fibreglass reinforced nylon for maximum durability. The design features a spline directly integrated into part which enables the recommended servo simply slides right in and gets tightened down by the same screw that is used as the pivot point. Simple, strong and easy to assemble.
The tilt is design around 28mm outside diameter motors with a hole spacing of 16 or 19mm, which is a very common motor size. The tilt can handle motors with a maximum motor size of about 33mm outside diameter. You can squeeze a 35mm motor but it’s not recommended, the bell might rub against the servo. DT750 type motors work well as they stick up high enough not to interfere with the servo.
Designed for 10mm booms the tilt simply attaches using zip-ties that are design to work as “mechanical fuses”, breaking and absorbing energy in a crash, protecting the important parts. It also makes it much easier to repair at the field, just bring some zip-ties.
The tilt is designed around the BMS-210DMH / TGY-210MH servo, which is a really strong and tough servo with great precision. It uses magnetic induction instead of a potentiometer. This means that in a crash, when the servo is subjected to way to much force the magnetic encoder looses track of where the output shaft is and it stops trying to make the servo fight the force, saving the gears. This servo also has a large spline diameter of 6mm which makes it possible to you to 3D print the spline directly into the tilt if you wish to make one yourself. This makes it super strong and slop free. It also uses a M3 servo horn screw, which I took advantage of by designing the tilt to use a 40mm long M3 screw as the pivot axis. This screw simply screws straight through the whole tilt and straight into the servo. The design also works with a other servos directly (list below) or you can use almost any servo as long as it has a maximum distance of 8mm from the bottom of the servo body to the bottom of the spline.
Material: Fiberglass reenforced black nylon
Weight:Complete setup with screw: 10.6g
Top: 5.7 g
Bottom: 2.3 g
Servo holder: 0.8g
Size assembled: L44 x H19 x W28 mm (L69 with recommended servo)
Motor hole mounting: 16-19mm hole spacing (standard motor layout)
Recommended motor size: 28mm outside diameter
Included screws: 1 – 40mm M3 2 mm button head stainless steel hex screw, 1 – Metal spacer, 2 – 6mm M3 2 mm button head stainless steel hex screws, 1 – Black M3 locknut
Servos that fit in the printed spline and the servo holder:
BMS-210DMH – Best choice
TGY-210MH – Best choice
Servos that should fit with minor modification:
BMS-390DMH – Needs the spacer to be sanded down
Savox SH0261MG – Not tested, but should fit with little to no modification
Savox SH0262MG – Not tested, but should fit with little to no modification
Totally overkill servos – needs a 1mm spacer:
(Align servos of the same size as they are rebranded Savox)
Here is a short list of servos that will work by screwing on the servo horn to the tilt top piece (any servo with a maximum distance of 8mm from the bottom of the servo body to the bottom of the spline will work):
