About 28 years ago, when I had my first Bellanca Cruisemaster, I took several friends flying, to get them hooked.  It worked too. 
Greg B bought a Stinson 108-2, the first plane he ever rode in as a 10 year old boy!
So I rode in it with a 165 Franklin. Then he upgraded. Naturally I encouraged the Continental O-470, but he went with the Pearson STC for the 220 HP Franklin.
Anyway, it was impressive. I see the rated RPM is 2800, instead of 2700 for a Lycoming, or 2600 for a Continental O-470.
Also, the idle seems a little high, 750 - 900 RPM. My recollection is that this engine has a fairly high compression ratio, and the cam has fairly long duration? It idled rough and sounded like a big cam. When the throttle was advanced, it cleared like a big cam high compression engine, and it ran very well. I thought it odd for such a spirited engine to be in a Stinson 108, which is so mild mannered.
I think it would serve well in an RV-8. Several have been built, perhaps their owners will chime in here and let us know?

I would love to see an RV with a Franklin. Maybe a alternative for the RV-14?
I always thought they were good engines, I mean they used to put them in helicopters. Can't say the same about a Continental.

Yes the correct site is http://www.franklin-engines.com/ and the CEO of the company is Roman Sadowski.

Is anyone flying a Franklin and doing aerobatics? Curious how it performs relative to a Lycoming.

Most Continentals use a bed mount, as well. No big deal. You're just not going to get one ready to bolt on from Vans.

Where did he get the motor mount on the RV8 in the photo, and does it require a redo of the firewall connecting plates on the RV8? A good friend has a Franklin engine, 220 hp and a CS prop that was going on and RV project, however, the builder backed away. The engine is ready to be assembled. This guy knows what he is doing on Franklin engines. He would be willing to sell it for the right price. Thanks.

Franklin engine - opinion from Poland
Hello to All,
I'm very new on this forum. At the moment I fly Jabiru J430, but some time ago I bought QB RV 7A kit. I'm located in Poland so I have quite good knowledge regarding Franklin engines.
Below please find some information which can be useful for you:
- 6 cylinder Franklin engine can be prepared for Mogas but this version is not certified and 180hp,
- 180hp version can be used with electronic ignition and fuel injection (you can get such engine including these installations directly from factory - for sure in Poland, don't know if it is offered by USA dealer),
- obviously our RV7A will fly with Franklin, this summer we plane to prepare engine mount which in fact is already designed for VANS aircraft and ready to produce,
best regards
from Poland

What is the cost and availability here in the states? What we really need here in the states is a lower priced engine. I don't know if Franklin is that solution.

Witek, welcome to the good ship VAF
It is good to have you here, please keep us informed about your build.
I flew a Franklin powered Stinson for almost 20 years, loved it.

Franklin 180hp Engine for sale
All,
Saw this on CL and thought some of the members might be interested. I talked to him and they came from a military sale. Cylinders were checked and he says they are in good condition. I know nothing about it and I am in no way connected to the seller.
