Turbo Glow....

Maybe...

Nope don't believe it! That Baron is way more efficient than that.

At least that's what I have to tell myself.

Yup

Ha...I'm brave but not brave enough to do business out here :D.

I'm doing training with a Piper guy... Rick Tutt

At night it can be a little nervous flying with a red hot glow visible through the cowl openings. Wait to you uncowl her at night and do an engine run up and see the entire exhaust system glowing red!

421 has the same glow...

Here is a pic next to a 421

Yup

She climbs...

Cruise climb gave 900fpm all the way to 17,500 on 75% power with 100OAT on the ground and 1,400lbs payload.

In cruise at 17,500, it was well LOP at 15.1/side and gave 183 increasing to 186ktas as weight burned off for a 3 hour flight.

The plane needs Gamis and both #6 cylinders are CHT limiting the power setting due to folds in the baffling. I expect after a tweak in the timing, Gamis, and baffling trimming I will be able to close the cowl flaps and get 190ktas on 15/side at 17,500.

For as large as this plane is, I am really surprised at its efficiency. Lots of wing helps up high.

After 15 hours, I've decided she is a keeper and will suit my mission better than my Baron.

AHHH %#$@........Matt what do we have to say for ourselves???

Jesse, how's the single engine performance?

Jesse how does it feel on the controls compared to a bonanza? Does it have the down force that the Bo has?

I really like the big windows. Makes the ones on the twin Cessna look tiny.

You say it has better viz out the front than the 421? Well that's got to be great then. Because I feel like the viz out of the 414 I fly is pretty dang nice.

Spent some time in the shop yesterday. It looks like I need a new AC compressor. It is cooling, but not to my liking so when it cools off I'll send it out for rebuild.

We also tightened up baffling around the #6 cylinders and we backed off the timing. The dual mags end up about 1/2 degree apart so we set the first to fire at 19.5deg BTDC.

As expected, I got a nice rise in EGTs and a nice drop in CHTs. A climb powered back to 38/2400 gave 1200fpm at a slow 120kias while only hitting 405 on the hottest cylinder. That jug dropped to 398 in the climb. Life is good. I know I'll get a boost from intercoolers but these numbers are fine for now under the worst conditions.

OEI performance averaged 350fpm between 8-9000'. As usual, slight changes in the ball make a significant difference. I always want for a yaw string when I do this.

Temps stayed under control, especially considering it was 110dF OAT and about 75dF at 8,000'.

Amazing thread, thx for sharing. Looks like a great bird. The charter operator affiliated with the flight school where I completed my PPL in England managed one of these. I used to walk by it on the ramp on my walk out to preflighting the little pa-28 for my lessons. I was always impressed with the size and presence of the Navajo. Certainly from a visual perspective to a non-pilot passenger, it's just in a different class from nearly everything else in the GA fleet short of a King Air or Pilatus.

That turbo glow pic is giving me nightmares, though, three days later...
