S Bonanza fuel economy vs J model....

[John Pleisse]

The S's are great....faster than models that followed...first year with solid state electric.

1.The best way to get a true airspeed picture is to do it with gps calculations doing 4 (N,E,S,W) headings. I would not rely on any gauge to give me a reliable TAS.

2.According to Mike Busch in one of his webinars 14.9 X FF = HP (assuming 8.5-1 compression and LOP), so 10gph is only 149hp or 52% power of a 285HP engine, I do not believe a V tail would go 170kts on 10gph unless you are up at about 18000 ft.

3.I had a V35 (1967) Bonanza with the IO520BB engine (285hp) and my gps true airspeed calc came out to be 171kts at 7500 ft 2500 rpm full throttle well ROP

4.I sold the Bo intending to go to a plastic plane, but ended up with the Eagle and am very pleased with it, much faster than the Bonanza.

5.The Bonanza has the tail wag I said I didn't notice when I owned it, but really noticed the diff with the Mooney.

6.Many V tails have an aft cg problem and it is difficult to load to gross without being outside the envelope.

7.Older Bonanzas like mine were not corrosion proofed at all and have magnesium ruddervators-corrosion can be a problem.

8.The gear is complicated and slower than Mooney gear.

9.The Bo controls are all cables, I prefer the pushtubes.

10.All this said, the Bo is a good plane and older ones can be had pretty cheap. I just like my Eagle more, but have may more amu's invested.

This is very true. There was a comment earlier that Bo's can haul more. This is true for about only an hour, then the fuel burn flies you out of the back of the envelope.

Interestingly, the same video that started this thread got posted over on BeechTalk and they only have 10 posts.............four of them are not about airplanes.

Bryan AKA "Beech Bum" has been grinding this axe for at least 3 years. I remember him from the red board.

The first time I saw it, I figured some know-it-all from Mooneyspace must have crawled up his crack over on Beechtalk.
