I had a fellow contact me with a 170B with the Franlin 220hp engine. What are your thoughts on this combination and this engine. I had heard that most people liked the engines but parts were hard to get. Then I thought I read in here one time that parts were available in the US. What are your thoughts? Thanks Gary

My first thought is its got to be nose heavy, especially if its got a CS prop, check the weight and balance. Youre looking at 11 gph, pretty thirsty for standard tanks. Too many unknowns for me, Id pass

Hi Tracy And thanks. They have moved the battery to the back of the plane. The empty weight was around 1450#. Gary

Do a search here as it has been discussed before. Thems that have em love em. The problem now is they are out of production and the parts availability is uncertain.

I don't like working on them. I haven't worked on the 220. I would much rather work on a lyc or cont.

I think the Franklin has some good features. There's a inspection cover on the top of the crankcase for a peek-a-boo view of the lower end. The cylinders have steel liners that can be replaced. They get 220 horsepower out of only 350 cubic inches, that's about the best power-to-displacement ratio of any flat GA engine. Trouble is, they use high compression pistons to develope that horsepower so it's a 100LL show only-no car gas. So no car gas savings. TBO is a bit low as I recall- 1500 hours, or maybe it was 1200.
So there's good and bad points,just like anything else. Gary, are you looking for a shortfield machine? If the price is right, it'd be hard to beat. Go for it!

TBO is 1500 hours, but a new replacement costs $10/hour (15K)... at least it was supposed to back when PZL was building them. That was alot less than a new Continental or Lycoming, at the time. Rumors abound regarding a buyer of the Franklin recip line from Pratt & Whitney, but they are only rumors. I am keeping my fingers crossed...
