AeroRest FAQ

This page is for those who still have questions about AeroRest after reading this page.

RQ1: How much friction does my arrow actually get from the AeroRest?

    AeroRest is a completely different approach on the standard arrow rest.  By utilizing next generation materials and geometry, AeroRest is still able to control your arrow with the minimum amount of friction.  How does it do so?  As most know, friction is force over area.  AeroRest use ABEC#5 ZrO2 ceramic ballbearings which have a tangent point of about 0.0002".  With only two such ceramic balls touching your arrow at any time, the total contact surface is about 0.0002" x 0.0002" x 2 0r 0.00000008" squared.  With such a number, one that approaches zero, defining area, the same can be said for friction (a direct relationship).  A quantity of friction that literally approaches zero...that is why our AeroRest is also known as a frictionless arrow rest.

RQ2: How noisy is AeroRest, and will it spook9 game as the contact point are nothing but ceramic balls?

    AeroRest uses ABEC#5 ZrO2 ball bearings as contact points for a few reasons (see RQ1 for one of these reasons). Another reason why we selected this material is because it is one of the few materials that have proven to work with carbon shafts to create a "natural" sound -- the sound of hard wood rubbing against itself in the wind.  That said, AeroRest is NOT meant to be used with metal shafts or shafts with metal on the outside -- a screeching sound will be the sound you hear in this instance.

RQ3: Beside not able to use metal or metal-shelled arrow, what other limitations does AeroRest have?

    AeroRest is a precision machined piece of equipment.  The top of the Aerorest finger that holds the ceramic ball bearings has a lip with a surface area of 0.0015 that is Type 2 level 3 hard-anodized to form a perfect arch to hold the ball within.  Due to this lip, arrows that has decorative wrap or collar cannot be used with the AeroRest.   Why? Well, in the case of decorative wrap, it will hinder the performance of the AeroRest by gumming the ball as the wrap will melt onto the ceramic and prevent it from functioning correctly.  In the case of a collar, it will dent the bearing lip and make function improperly.

RQ4: How large of an arrow shaft can the AeroRest accommodate?

We at Firenock understand that as an arrow's diameter increases, an arrow's reaction time decreases, thus needing less control.  In the instance, then, if an arrow shaft is has an ID larger than 0.350," AeroRest is designed to still work with the upper finger removed.  This modification will create an arrow opening slot to allow arrows as big as 27.5/64" to pass through.  

RQ5: How small of an arrow shaft can the AeroRest accommodate?

We at Firenock understand that as an arrow's diameter decreases, an arrow's reaction time increases, thus needing more control.  In the instance, then, if an arrow shaft has a smaller ID than 0.350," one should always use the upper finger of the arrow rest to make the rest a more controlled launching point.  For any adjustments, the AeroRest comes standard with 18 GR2 titanium spacers (9 of 0.11 mm thickness and 9 of 0.44 mm thickness).

RQ6: Why are there two standard AeroRests?

We at Firenock understand our customers all have different approaches on how they use their arrow rests.  To accommodate these differences, we offer our standard AeroRest body with two different side bars.  ARST0H boasts a GR5 titanium side bar, providing the most durable and long-lasting initial setup, however thus requires more care within that initial setup. ARST00, on the other hand, comes with a 7075-T5 aluminum, laser-marked side bar which provides one a little more guidance on daily adjustment but is, of course, not as durable. Either way, both side bars are the same weight, so when purchasing a standard AeroRest, it becomes only a matter of preference.

RQ7: How tight a gap between the ceramic ball bearings and my arrow do I need for each model of the arrow rest? 

The size of the gap depends on the cock van vane configuration...

If your cock vane is in the up position, there should not be more than 0.0005" space between the upper ceramic ball bearings and the shaft.

If your cock vane is in the down position and all three fingers are being used, one should leave a gap more than 0.008" or the thickness of four 20 lb pieces of paper between the arrow and the top finger.  If only two fingers are being used, there should be no gap -- your arrow is resting upon the fingers.  As long as your arrow does not fall between the two fingers, your good to go.

RQ8: My arrow just does not shoot right and I keep getting a high tare, what is going on?

This could be caused by a few reasons:

  1. The arrow's spine is too weak for your bow and thus bends past what is allowed inside the AeroRest, forcing the ceramic ball bearings to bottom out and loose their ability to control the arrow launch cycle.
  2. The AeroRest fingers' internal spring pressure is set too low and will thus cause the arrow to behave as described in Reason #1.
  3. The AeroRest is setup where your arrow's nocking point is non-perpendicular to your string and will thus cause the arrow to behave as described in Reason #1.
  4. The upper cam's timing is more advanced than the lower cam's, forcing your arrow to slap itself down on the AeroRest, and will thus cause the arrow to behave as described in Reason #1.

RQ9: My AeroRest's ceramic ball(s) are sticking and my arrow's flight has become inconsistent, what is going on?

    Like all equipment with precision parts, things can go wrong.  Shooting dirty arrows or arrows with decorative wraps can deposit residue onto the ceramic balls.  This the main reason for sticking (and thus inconsistency in control in the AeroRest and thus on your arrow).  In most cases, simply clean the ceramic ball(s) and the inside edge(s) of the finger cup(s) with acetone and some Q-tips.  If there was accumulation on the ball(s) to the point where scratching began the inside of the finger cup, you contact us here for replacement parts.
