Aero Protect is offering the half arms in 1 inch, 1.25 inch, and 1.5 inch lengths and full arms in 2.5 inch and 3 inch lengths for JR, Hitec, and Futaba for use on all control surfaces. If you are using the Hangar 9 titanium Pro-Links or other linkage that has a right and left 4-40 thread we are offering the AirWild arms with LEFT thread RCL87’s.

Conventional servos, whether they are an entry-level servo or a state-of-the-art coreless digital servo, attempt some scheme to seamlessly contain its output drive shaft to the servo casing. From an economical plain bushing based spport of the servo drive shaft to the precision oriented ball-bearing setup, no servo manufacturer has successfully eliminated the presence of play in its output drive shaft which “wobbles” about the case-shaft junction. Unfortunately this is also an inherent nature of all mechanical devices and will only worsen over time.

The most consequential effect of this “wobbling” output is the significant loss in precision of servo arm movement. What this means to our radio-controlled models is the inability to maintain exact deflection of the control surface or element and furthermore, presence of undesirable movements.

AirWild Hobbies' MLP Servo Arms effectively address this inherent servo issue with our patent pending Minimal Lateral Play, or MLP servo arm architecture.

MLP architecture cleverly dampens the “wobbling” output effect of any servo by lowering its rotational plane very close to the case-shaft junction which is the origin of the undesirable output play. This effectively reduces output shaft's movements in the X-Y planes due to poor fit, deviated tolerance or dated wear in servo bushing or ball bearing.

The significant gain in servo's output precision will equally benefit an everyday low-cost sport servo as well as a top-of-the-line, high-performance digital servo. Furthermore the innovative geometry of our MLP servo arm's reinforcement ribs offer awesome torsional resistance to high loads often seen in typical giant scale control applications.

Unlike conventional servo arms that often pre-drilled multiple holes for securing linkage devices, AirWild MLP servo arms feature only one 4-40 tapped hole (two for full arms), plus a scored center reference line for drilling additional holes as needed. Such layout offers several benefits over the conventional setup:

Extra holes stand to weaken the structural strength of servo arm under high loads.
When requiring additional holes use the scored center reference line as guide to assure centering.
Location of the new hole can be exactly placed.

All and all, MLP Servo Arm is just a better, smart and innovative solution to your precision control needs. So next time before you upgrade your servos for better performance, try out a MLP servo arm. You will be pleasantly surprised!
