Totally agree. This is what I’d buy if I didn’t already own mine. Of course I spent 3 years getting mine completely upgraded (1 year just in the avionics shop….terrible experience). Somebody is going to get luckier than they deserve to be

P 2’s are very fast, I test flew my 1962 A55 P2 for the first time since a 90,000 annual.

Breaking in new engines at 3,500 AGL , IAS was 192 KTS and TAS at 3500 was 205KTS.

ROC was 3,000 FPM INITIALLY. I may sell it in the near future.

If I could marry it and have little B55 babies, I'd be in heaven.

No sir, I just use a portable bottle. The built-in bottle takes up a good bit of the nose baggage area. I only use it about twice per year anyway.

My panel took about 2.5 months at Freedom Aviation in Lynchburg, VA. He cut the panel on site.

I remember flying in a similar Colemill 55, doing single-engine work and climbing at close to 1,000 feet per minute.

What were your power settings? Typically, during engine break in power settings are quite a bit higher than normal cruise power. Have you established what the TAS is at normal cruise power settings at 7,000 or 8,000'? I'm curious how that compares to the 3 IO470 Baron's I have owned.

With the old high time engines, max cruise at 7500 was 210 KTS in the winter, a little less when it’s warm. With the new engines it should be more, I am not there yet.

With the old engines I could cruise 198 to 202 depending on weight and temp at 12,500.
With 12 GPH PER SIDE ROP. New engines should increase those numbers.

After the engines are broken in I will have more data and pictures.
Also this is a clean wing with VG’S and a light weight airframe.

The P2’s aren’t significantly faster than the 470’s down low but up high they’ll hold speed well. We have a “slow” P2 and still true 190ktas at 13k and 180ktas up at 17k. Also climb performance is impressive even at gross weight.

Yes typo, 12 GPH RUNNING AT PEAK.

Below 5,000 a P2 will indicate in the yellow if you don’t reduce power so at 3,000 a P2 is only about 10 to 15 KTS faster than a Baron with IO470’S.

I know, the skeptics won’t believe it until I post pictures.

With old engines and the right one shut down at 10,500. With the old panel.

Last picture at 12,500 with high time engines.]

After breaking the engines in I will get new data at 12,500
