My experience with two different powered wheelchairs was the same as PaulM's - it could somewhat move a C172 on level concrete, but not on grass. I believe they were 2x250W and 24V. My current attempt is a poor man's B5 clone - 2x 500W@24V DC motors with an integrated 1:6 gearbox with a 13T sprocket turning child ATV wheels with 49T sprockets, attached to a platform; front wheel will be 'loaded' with a winch and the contraption will be RC controlled via an Arduino board with a simple sketch to do the differential turning and so on. The next one will be a BLDC powered contraption with tracks instead of wheels and a scoop-like mechanism to hold the nosewheel.

First OPP I had made... I think I paid like $10 for a set of two (two different plastics).

That, partly, explains the price change...

Don't those kerosene heaters produce a lot of moisture in addition to heat? We have a diesel "torpedo" style heater that has a separate outlet for the warmed-up air and another one for the exhaust gasses.

I understood that closed cell foam is used exactly because it does not soak up / retain water.

Did you believe them? I wouldn't, especially WRT flooded batteries, but probably not for the GEL ones either. But I'd believe you. I mean, we're pushing <1C, do we really need to push it differently than a car does? I kind of doubt our voltage regulators are that precise, and flying often is said to be the best way to keep them batteries healthy.

I just bought a spare KI256, so it might be never, but when I get around to removing vacuum, I plan to replace the pump with the B&C backup alternator. The KNS80 stays put till I do something like 2xIFD or some such.

+1 for Don and his video.

No, only if you use the VOR for navigation; but it is literally free (I have a KNS80 and a GNS430W and do dual checks) so why not.

It gets worse, much worse: https://aviation-safety.net/wikibase/183669 - a TB20 with 4POB, all perished; quoting from the accident report (from Spanish equivalent of the NTSB): The investigation has determined that this accident was caused by the loss of control of the aircraft following the loss of part of the left wing after an impact with a vulture. The TB20 is not a light sport plane with a wimpy wing...

Was it possibly traffic known to them, and a drone in the sense of an e.g. Predator, not a wimpy quadcopter from HF?

I thought the TIT limit on a TSIO-360-LB in a vanilla M20K is 1650F, which I round down to 1500F for peace of mind. Should I lower my threshold, or did I miss something in the POH?

Some would argue that there are quite a few pounds of useful load to be gained by removing old, unused stuff, including wiring. But in principle one can leave the disconnected wiring tucked away behind the panel.

Just removing the device is no work; but you probably also want to remove the rack it was installed in, which is more work. Which leads to wanting to remove all the wiring that is terminated at the rack, and this is where the cost lies, as there could be really lots of it, going to many other units in the panel and elsewhere (antenna, etc). Do it right, don't defer...
