Dynamic balance on geared engines

After flying in Ben's and Aaron's planes, I felt like mine wasn't quite as smooth. Ben's is ridiculously smooth, like turbine smooth. Aaron's is also super smooth. Mine was fairly smooth but not like theirs. At cruise I felt a slight vibration in the yoke. I'd heard mixed things about dynamic balance. Some said it was BS... some said you can't dynamic balance a geared prop, especially if there is any slop.  

I talked to DynaVibe who make the tool. They referred me to a shop just 20 miles from my home base. I called the guy and he said it would work. He hadn't done a TwinBo but had done 421's. Said RPM's are RPM's... well for $400 /side I figured it was worth a shot. It took all day with about 5 runs on each engine. Right side went from .4 IPS to .02. Left side went from .1 IPS to .02. Flight home no more vibration in the yoke.  

I'll have a longer flight on Weds to test. What say you, $800 down the toilet or $ well spent?

no reason for the attached photo other than I took it while waiting around...

It works

Got a chance to test it out the ArticAir AC today. After the initial one didn't work and a return for repair, I'm happy to report I'm pretty dang happy with it. I feel nice cool air hitting the back of my head. It was over 100 degF today and it definitely made a huge improvement. It didn't freeze me out but it did bring me from dripping sweat solidly into no worries territory. If I had to guess I'd say it lowered cabin temps by about 15-20 degrees. I went for a gas run and there was a line at the pump, so I just let the engines idle at 1400 rpm and let the AC rip and was happy as Larry sitting inside with the storm windows shut and cool air blowing. definitely a leg up for this Tbone!

TBone Aircon

After a bit of a snafu I finally got the ArcticAir real AC 24v installed. Takes up about 2/3 of the extended baggage compartment but no biggie since I primarily use mine as a 4 seater. It's also technically a "portable" unit and I can fairly easily remove it in winter.  The first one they sent me didn't work... it blew air but wasn't cooling. I had to send it back for repair and now it blows cold. I had my mechanic install some anchors for it, since I don't want a 50 pound box becoming a projectile, and they also install a 60 amp breaker, power, exhaust out the tailbone and drilled some holes to route the blow tubes through the hat shelf.

Covid escape

After being virtually locked up for nearly 4 months it was time for a break, luckily the Tbone is a great family escape machine.  This sounds crazy but it's hard for me to imagine taking family trips in a plane much smaller than my Tbone.  I still don't have the air-conditioner back though...  going to Arizona with no AC!  grrr...  

But wee really wanted to find some place that was 100% open and Arizona fit the bill... Montana looked good but the restaurants were take out only...  MOAB is open but it was scorching hot.  Arizona is hot too, but at 5k ft it's actually perfect.  Mid 90's in the mid-afternoon, but that's perfect since you're hiking to the places like Slide Rock and the water there is cold.  It took about 3:45 but was thankfully mostly smooth, except for the descent into Sedona which was typical teeth breaking severe turbulence.  Oh well.  Great trip though, awesome hiking, great restaurants, spa and always beautiful there...   and a smooth flight home.

Return from annual

The plane out of annual finally.  I had them install an ArcticAir real air conditioner.  They did a fabulous job with the install with nice safety straps and hooks to secure it.  Unfortunately, I'm now the owner of a super heavy and expensive fan...  it blows but doesn't cool.  Arggh, a few days on the phone with customer support and no fix so far.  I'm really hoping I don't have to send it back...


The other nice thing about this unit is it's easily removable in about 10 minutes, so there will be no need to lug it around in the winter.  I just gotta get it working, it's 100 deg+ already.  

On the bright side I 3D printed this awesome little Beechcraft keyboard holder for the Avidyne bluetooth keyboard.  https://www.thingiverse.com/thing:4327439

Annual

Opened up my 60 year old airplane for annual and it looks like it just came off the factory floor.

Annual time

Dropped off my plane for its 3rd annual in my ownership.  The main thing is I'm having them install a real air conditioner.  I bought the ArcticAir 24 volt real ac unit.  It just seems like summers are getting hotter and hotter and it's just so much nicer to have a cool cabin and not be drenched with sweat by the time you're airborne.  Also my older son is prone to air-sickness and I've noticed he does better with nice cool air blowing on him.  The B-Kool ice cooler works reasonably well but it's just a bit of a hassle to load it with ice.  Otherwise no real squawks this year and hoping for a quick turn around.

Since the shelter order my Pilatus flights have been few and far between.  Oh well, In the mean time, I always have my sim.  The new x-plane 11 beta with Vulkan update is really good.  Here I'm having fun flying the C90.



With the huge curved flat screen it's super immersive.  Here I had to back up a few feet just to get the whole thing in the frame.
