Yes, we are working on a turbine conversion for the Beaver!

Serv-Aero's current major products include a single leaf tailspring kit, a fuselage fairing, a modification to the horizontal stabilizer, and an elevator servo tab kit - all for the  Ayres S-2R / Thrush aircraft.  We build a PT6 conversion for the Otter; and a R985 conversion for the Stearman


Stearman/R985 Engine Conversion  FAA-PMA'd Normal Category kit, with inverted fuel and oil systems.  Comes with two PS5C carbs, custom cowling, engine mount, inverted systems fuel and oil tanks, installation parts.  Oil tank, oil cooler, and battery mount behind aft cockpit.  Price on request.

Stearman Four Aileron Conversion
This conversion is approved for any engine installation in the Stearman.  All aerobatics are done much crisper.  Four stock ailerons are modified.  All parts are furnished to modify wings and install ailerons.  Anti-servo tabs are added to the lower ailerons to lessen control forces.  Price on request.


Ayres S-2R / S-2D Spring Tailwheel Kit
Nearly 1200 of these conversion kits have been sold.  No more flat struts or rough rides.  Several improvements underway now - stainless steel spring guard, spring nose restraint system, and improved spindle housing features.  Research on spring improvement is ongoing.  Contact us for further information.  Kit is still priced at $3,605.25.


Turtleback Fuselage Failing For Ayres S-2R/Thrush
This fuselage fairing makes any Thrush 7 - 10 mph FASTER  The fairing smoothes out the rough air over the tail, and, together with the horizontal stabilizer we offer, virtually eliminates the tail shake.  Obviously this will result in less maintenance and reduced pilot fatigue; and increase your productivity.  Some operators choose to ferry at their current speed and save fuel.  The modified aircraft will actually weigh approximately 5 pounds less - and get some more weight off the tail!  Currently we are undertaking a project with the FAA to allow this fairing to be shipped predrilled, but unassembled.  Assembly instructions, photos, drawings and fasteners would be supplied.  Contact us for further information.  Priced at $2,895.00.


Ayres Thrush Horizontal Stabilizer Airfoil Mod
Those operators that have tried this modification will never change.  This mod adds only 8 pounds to the weight of the original fabric covered stabilizer - and substantially reduces the tail shake and cracking.  When used with our companion fuselage fairing, the pair virtually eliminates the tail shake - and with a minimal weight increase, unlike the sheetmetal stabilizers.  The modified stabilizer has a leading edge that helped smooth the airflow over the tail.  We clean your unit, add a modified 6% NACA airfoil, sandblast, and paint the modified unit with IMRON.  Any required repairs to your unit are extra.  This modification is priced at $3,495.00

Elevator Servo Tab Conversion For Ayres Thrush
Serv-Aero has offered an approved kit for providing an elevator servo on the fabric covered unit.  Installing this FAA-PMA'd product will result in lower stick forces and increased pilot productivity.  Priced at $715.00
