The International Cessna 170 Association

This topic brings up a new development in Props. I had a 1948 C170 with the C-145-2 (O-300) motor and metal prop with skullcap spinner. After purchasing a majority interest in a large volume MT Propeller distributorship, I looked to see if I could put an MT Natural Composite Fixed Pitch Propeller on...

How To Groundloop Your Taildragger Judging by how frequently it is performed, the Groundloop is indeed a popular maneuver. The Groundloop is an extreme low-level figure that is highly acrobatic in nature, which may be executed in many exciting variations. It is customarily performed as the last figu...

What a great time!! Mike Woodson from Seattle WA (in his C180...if you saw our camp you know we needed a 'mule') & I arrived Tuesday PM - July 19th, set up our 'home' and settled in. There were less than a dozen planes on the field at the time. As the week progressed, our 170's arrived and took ...

I counted 36 in the designated parking as of Sunday noon. A few more arrived after that, but I dont have ab exact count on those.

My EGT took a dump. I will use this as an excuse to replace it with a combo CHT/EGT. Current EGT probe is on the rearmost pass side exhaust stack. Two questions: Which cylinder should I place the CHT probe on (O-300 on a '47 C-170)? Wag Aero has two metric sizes available, Which size do I order to p...

We have a max of 40 spots available in the prime real estate between the EAA field repair station and the Ultralight Reb Barn on the west side of the tramway. I NEED your Contact information!!

Tye, It seems all the costs are involved in renting test facilities, hiring engineers to evaluate and report on test results, needed to satisfy the FAA's engineers. I will ask if he has to also pay the FAA to read and evaluate his proposals. Remember, you can put one on, but you would need to declar...

My MT source owns STC's for nearly a dozen A/C to use the MT prop. Each one took nearly 18 mos to get and between 40K-50K. FAA is real picky on tests to grant 337 on props. A tremendous amount of vibration, stress and endurance testing must be done, both on test stands and on actual A/C of the type ...

MT Propeller has a hub for the Cont O-300 / C-145 engine for use with their Electric 2-blade prop. The hub fits the 541 series crank (newer). An adapter is avail for the SA-3 style flange. This prop is 'certified'., but no STC exists. It could be put on and used on a 170 only as EXPERIMENTAL. We wou...

Can anybody answer the question regarding a field approval and 337 for intallation of the prop that is STC'd for the 172? So if one were to buy one of these electric MT props for the 172, install it exactly the same way, could you get it signed off so you could fly with it?

Here is the url of the MT Propeller site that details the operation of their electric props. Still waiting on word of a hub that would bolt to an O-300.

MT Props are laminated wood core that is wrapped in a protective composite. They have done exhaustive dynamic testing and found extremely limited instances of harmonic vibrations (mostly on very high compression, electronic ignition motors). They are lighter, have a much lower polar moment and have ...

I am in business with one of the two US Sales Representitives of MT Propellers (Germany). I will ask Larry about the electric CS they make. If one of tested design from a strong and experienced mfr is avail for the cost of the STC, it should be investigated. BTW, The MT natural composite 4 and 5 bla...

Bulduc Aviation in the Mpls Area is 3rd generation shop that is known for small Contenental rebuilds. Very reasonable pricing also.

We will most likely have to start a new topic just to discuss the fun of OSH arriival. Start by getting a copy of the NOTAM. It is at the EAA site http://www.airventure.org I have only missed once in the last 12 years. The NOTAM may make it seem more complex than it really is. My tips(IMHO): 1. Come...
