Dave Thorsness from Foley MN has been doing Cessna wings and controls for over 30 yrs. He has jigs to be able to completely start a wing from scratch if needed. Very fair pricing.

Not 24 factory workers, but 4 cute Volleyball stars

I would have let more of them on the wing, but these were the only 4 who did not have paint scratching 'bling' on their jeans.

I sent mine to SCS Interiors and they did a wonderful job.

I love my new panel. Also had the wheels leather wrapped after this pic.

George, There is a MT Prop factory bulletin referenced in the TCDS of the MT props that is a list of every governor known and as new ones come to market, they add them. The MT prop only requires simple oil pressure to increase pitch. All standard governors do this. I used the MT governor in my proje...

The STC is a 'propeller change' STC. It is approved replacing ALL existing propellers with the MT as long as you have any version of a Lycoming -360 engine. Literally on the STC it shows approved engines as "Lycoming [ ]-360[ ] Series Engines".

This is the panel of my Super 170B. The control wheels and grab straps are now covered in black leather.

The STC that approves the MT composite hydraulic constant speed propeller has recently been amended to approve installation on all 170/172/15 series aircraft that are powered by ANY version of a Lycoming -360 series engine and any hydraulic governor. Two props are currently available. A 83" 2-b...

I have the DelAir O-360 on a 1955 C170B with sportsman kit. Plane is 1400 pounds empty. Prop is a MT composite 3-blade constant speed.

Resize of DSCN9576.JPG The RPM Range restriction is in placed with metal props because of very strong, damaging harmonic vibration levels were the natural frequency of the metal prop matches one or more of the primary order vibration pulse frequencies of the engine. You may not feel it, but the pro...

N170KW-104.JPG Metal props on a Lyc -360 all have this limitation due to the natural harmonic frequency of the metal blades working at those RPM's WITH engine firing pulses that result in dangerous vibration levels in the engine/prop. There is a heavy harmonic balance ring that is installed behind ...

I have used the shop in Foley MN several times. Good work. Very reasonable.
