Pinecone

Ah, I knew that.

I just ordered one of these, as I could not get the angle I like. https://www.sportys.com/ram-double-socket-swivel-arm-rap-b-200-2u.html MyGoFlight has a nice articulated arm, but around $130, plue the cradle, so over $250 for the setup. I use a full size iPad in the CAP C-182 I fly, but the Mini fits better in the Mooney.

Nice looking boat. But is it a planing hull??? Laser 28 hull was designed by Bruce Farr. Sort of the Roy LoPresti of boats.

Maybe. One airplane I looked at, a 252 with TSIO-360 was overhauled in 2010. Overhauled again in 2011. Then was topped (all 6) in 2019, then have one removed and reworked in 2020 and another one in 2021. I passed.

Having just purchased a 252...... The 252 has an intercooler and an automatic waste gate. So on takeoff, you push the throttle forward and check the manifold pressure to make sure nothing screwy is going on. In the 231, as I understand it, you push up the power, keeping an eye on the manifold pressure, stop before the limit, let the turbo catch up, then fine tune. During climb, you do nothing to the power settings in the 252, versus tweaking the manifold pressure in the 231. In cruise, as I understand it, in the 231, as you change fuel flow or RPM, you have to fine tune the manifold pressure. IMO, the 252 is what the 231 should have been. You can add an intercooler and auto waste gate to a 231. The 252s also have 24 volt systems and speed brakes are standard. Every one I looked at had oxygen, but not sure if it was standard. Some of the speed comes from better performance in the flight levels. 252 has a max ceiling for 28,000, and a critical altitude (max altitude for full rated power) of 24,000 feet. The neat thing is, the 252 can be converted to Encore specs. You convert the engine from -MB to -SB. All external, prop governor and waste gate. New manifold pressure gauge and tach markings. Lower gear legs, doors, dual puck brakes, master cylinders and the control surface weights. This gains you 230 pound increase in max gross weight. My 252 has been converted and has an 1119 pound useful load. So even with the Monroy long range tank STC, I can fill the tanks, put in two people and still carry a full baggage area. Flying mine home, I was at 13,000 feet, showing 173 KTAS on 13.5 GPH running rich of peak. Now for the bad news. They only made 231 of the 252s. And since they are so great (personal opinion ), they seem to show up for sale less often and at higher prices.

The JPIs record Total time from power on to power off. Also they do Tach Time based on revolutions based on a certain RPM being equal to clock time. That RPM is setable. Based on comments here, it seems that the Mooney uses 2550 as the base RPM. Although it seems that the common RPMs are 1800, 2050, 2300, 2400, 2566, and 3000.

The OWT of different types of O2 was debunked some 25 years ago. Look at the archives of AVWEB. All O2 comes from liquid oxygen. It all comes from the same source. If medical O2 had more moisture, why do hospitals and full time home use add bubbling through water to humidify it? MANY people have been filling their aircraft O2 tanks with welding O2 for many years. And the O2 system manufacturers sell the setups to fill your internal or portable tanks from welding O2 tanks.

Hmm, I would not think there is room between the trim wheel and the emergency gear extension. But this seems like a great place.

Yeap. Most sailboats have a prop brake. Unless, like mine, which had a folding prop. Folding props are found on some motor gliders. What sailboats have you had? We had a Laser 28. Clocked 18.5 knots on a beam reach with the spinnaker up.

I know the Honda CBX 6-cylinder motorcycle back in the the 70s had an issue with porosity between cylinders. The cylinders were very close together and the casting was quite intricate.

Agreed. But porosity is not a crack. Yet.

From other threads, I recall the switching from vacuum to electric speed brakes is not that difficult. Remove the two SB cartridges and the associated lines and bellows (actuator), install the electric ones and run some wires. An of course, the hard part, paying for them.

What do baffle seals have to do with EGT????? CHT yes, EGT, how?

That is the plan. Especially since I just ran the figures, and I will get a pay raise when I retire.

I am trying to determine the CHT on my #6 (252). On the JPI 700 it reads 40 degrees higher than the other cylinders much of the time. But sometimes it is close to the same as #5.

Makes sense. With a cascade you probably only have to dump the low pressure cylinder, and not waste too much product.

DUH. Multitasking poorly. Trying to work and read MS at the same time. I need to pay more attention to MS. Ok. So if I were to put in a JPI 900/930 or Garmin EIS, I would just set it to record tach time with a 2550 RPM base RPM?

How long does it take to write and post a paragraph about what is going on? I am not looking for in depth, but just how are things going.

Plane it too new to me, no one has sat in the back. Next time I am out there, I will try it out. I think the pax feet will be forward of it, unless they raise their knees a good bit.

I would love to join, if someone would process my membership.

My question is the leak from the exhaust area past the valve or from the combustion chamber area. If in the combustion chamber area, I would be worried. Exhaust port area, concerned, but less worried. Mainly due to the pressures in each area.

Thanks, that was what I was looking for.

Happy?

Mine is mounted to the floor behind the pilot seat. That is what was done by a previous owner.

Thanks. But my serial number is 25-1057, so it runs off the alternator Aux terminal. But it does not match run time (timed by GTN650 time), so maybe it is getting RPM info from the alternator.
