Crafted expressly for tail rotor applications (760µs/560Hz) where high performance is
required in a standard-size package, this may be the perfect tail
rotor servo for your Goblin 630, Pantera P6, T-Rex 600, or any 700-class model. These are the
1. Features a brushless motor. Electronic commutation
means there's no excess heat and 5X longer life because
electrons don't wear out.
2. To reduce weight we created a composite case. Instead of a simple extrusion, we CNC-machined the center case from a solid billet of 6061-T6 aircraft aluminum. Next, we mold the upper and lower case sections with tough Nylon 6,6 and to reinforce it, we press bronze inserts for the gear shaft pockets. The composite construction results in a case that's significantly lighter than an all-aluminum case, which because the tail rotor servo is behind the main shaft helps the CG without sacrificing strength.
4. The case is assembled with 10 (ten) Allen-head machine screws
instead of four (like competing designs) for greater rigidity.
5. Dual dual ball bearings?
Yes, of course, but instead of ordinary ABEC-3 bearings, this servo has two ABEC-9
bearings for ultra high precision.
6. You also get metal gears, and key to higher speed is using lightweight gears (25T spline). Added to which, these gears are wider than usual thus increasing the surface area for long wear.
7. Optimized for high voltage
(HV) battery packs (7.4V nominal) or 8.4V from a BEC.
8. Since centering is the sine qua non for a high performance servo, this servo has MIL-SPEC components. Along with a genuine Nobel potentiometer,
this means the best possible performance because we don't compromise in
our goal of building the best mini-size servo money can buy.
9. If you believe protecting the electronics against vibration is
important then you'll be happy to learn how instead of a cheapo piece
of foam we protect the electronic components of the PCB (printed circuit board) against vibration with potting compound.
This is exactly how the military and NASA bullet proof their
electronics. And quite honestly, it's a pain in the hind quarters, but
we think of it as going the extra mile because like you, we're modelers
too. Or put another way, we fly what we sell.
Bottom line? The ProModeler tail rotor servo
is the one you
want because it's better. It's better because it's brushless, strong, fast, and centers superbly. It's
plenty strong for models up to 800-class.
