rotorblade airfoils

RotorBlade Airfoils™ are for use with model Autogyros. They are laminated of AAA basswood and 8-12 lb. balsa. The basswood leading edge, which makes up 25% of the chord, aids in chordwise balancing which is critical for Autogyro rotor system performance. They are only sold in sets of 4.

The profile of our RotorBlade Airfoils™ is the undercambered SG6042. Back in February of 2000 Les Garber and Bill Friedlander performed wind tunnel tests on several airfoils as applied to model autogyros. Among the many profiles tested, the SG6042 produced the most lift. Our customers report that after using our RotorBlade Airfoils™ on their R/C Autogyros, the flying performance is superior to anything else they’ve tried.

We offer four chord sizes in our RotorBlade Airfoils™: 1.5”, 2.0”, 2.375” and 2.75”. They are available in various lengths as listed on our Order page. Our customers purchase our airfoil stock to make rotor blades. As such, you will need to cut them to length, make and apply plywood mounting plates, drill the mounting hole(s), and balance and finish them for your model. Balancing and finishing tips can be found by clicking here.

RotorBlade Airfoils™ are only sold in sets of 4.

The four RotorBlade Airfoils™ that come in a set are weight-matched. Each airfoil is weighed and then matched up to make a set. The maximum weight range of the airfoils in a set for each chord size we offer is listed below.

CHORD SIZE	1.5” [38.10mm]	2” [50.80mm]	2.375” [60.33mm]	2.75” [69.85mm]
MAX WEIGHT RANGE	1 gm	1 gm	2 gms	3 gms

For example, the difference in weight of the four 2.375” airfoils in a set will not be more than two grams. Please note: Requests for specific weight RotorBlade Airfoils™ will not be fulfilled.
