Control Quadrant Upgrade
Available for CIRRUS SR20, SR22
Tamarack Aerospace Group’s Control Quadrant Upgrade results in greater fuel efficiency with reduced engine wear by means of a propeller RPM control lever. The Prop control lever for CIRRUS SR20 and CIRRUS SR22 reduces noise significantly while providing a much more relaxing and enjoyable flight for both pilot and passengers.
Customer Feedback From the CirrusPilots.org Forum:
“Although still expanding the envelope of experience with this upgrade, after roughly 20 hours and an inspection at Leading Edge I am confident this is the single most cost-effective modification made to my plane. I am going slowly because of the adverse comments above, all of which so far appear unfounded. Typically, on long cruises I am at 19,000′, MAP at 29.5 runnning between 15.5 and 16 gph at 2400 RPM, 80% power with no reduction in speed. I do lose a couple knots reducing RPM to 2350. I have no problem controlling temperatures which, across the board, remain well within normal for oil, CHT, EGT TIT. If there are problems, they are not reflecting on the instrumentation. The cabin is much quieter, but I can offer no db reduction measurements; however, if you would like to know how it will sound in your plane, take off your headset, reduce the RPM from 2700 to 2400 and listen. Holding RPM constant, I am able to reduce FF to 15 gph without roughness and of course, power is reduced. I believe the MT Propeller 4-blade is very efficient at these levels and further accounts for reduced vibration and noise levels. The claimed fuel savings do not appear to be puffery. At 1 gph and zero speed loss this mod will pay for itself in about 400 hours or less, and range is increased. If you don’t plan on that much flying, you will enjoy the enhanced control. These guys deserve a round of applause.”

“We think the conversion is just perfect for us. We only go as two and this allows us to literally carry anything we want. Fortunately we’re healthy and active so this means golf clubs, mountain bikes, and enough shoes to hike, bike, golf, white water raft and yes even dress up (if needed). I may even have a couple of rear seats for sale. 🙂 ”

~ Limitations & Conditions ~
The installation should not be incorporated in any aircraft unless it is determined that the interrelationship between this installation and any previously approved configuration will not introduce any adverse effect upon the airworthiness of that aircraft. The approval of this modification applies to Cirrus Design SR20/22 airplane models delineated below.
- This STC is applicable to the following serial blocks of the Cirrus Design Aircraft:
- Cirrus SR20: Serial Numbers 1005 through 1885
- Cirrus SR22 Serial Numbers 0002 and subsequent without Garmin Perspective Avionics installation
- SR20 airplanes equipped with Hartzell BHC-J2YF-1BF/F7694 propeller assemblies must have a placard installed reading “Avoid operation between 1900 and 2200 RPM above 24” manifold pressure.
