Default Tire pressure monitors

I did a VAF search on tire pressure monitors and found two threads on subject, one in 2010 and the other in 2013. Since things change quickly in the device world, I thought it was time to bring it up again.

My RV-10, despite its air stop tubes, has to be blown up every couple of months. I know you just look at the tires, but with the pants and large tires, the difference between 45 and 30 is not huge. It is definitely much harder to move with low tires, but most of the time my flying is not pre-planned trips and discovering the tires need air delays things a good half hour or more and the passengers are not impressed.

Range for me is not a big issue since my bedroom is 40' from the airplane. I am going to balance my tires this annual in two months, so weight is not a big issue. Not intefering with non moving parts inside the pants is obviously critical. Buying different tubes would not be an issue since my current Airstops leak, (The ones I had on my --6A didn't.)

So any ideas, experience or suggestions??

I'm tempted to try these things, but all the ones I see look huuuuuge compared to the standard valve cap, and I don't think they'll fit given how close the valve is to the inside of the wheel itself (on a stock wheel).

Anybody try one that fits and works?

Default forgive my ignorance

I have not yet put my -10 on gear, nor fitted the wheel pants to her.

My pressure recovery wheel pants (all 3)on my 6A have spring-loaded hinge doors about 1-1/2" square through which I can access the valve stems readily. Airing tires takes just a minute. The hardest part is rolling the plane to the spot where the stem is in the "doorway" for each wheel.

Why is this not standard practice on the -10? Do you really have to remove the pants to air the tires? Surely there must be a work-around.

Snap in plugs from a local hardware store are a simple, fast, cheap option.

And these answer the question about TPMS how?

I just ordered this yesterday to see if it would work.

The caps look huge and I have my doubts but I'm going for it anyway. I will let you know as soon as I see the results. Ed

Friday night exercise routine.

There should be a location on the pants where a1/2" hole is not an issue. A 1/4 inch drive with a socket takes the valve stem cap off quick and easy. Then a 6 " flex line extension spins on to allow filling. Reverse the order and you are done in less than 5 minutes for both mains. Try using nitrogen vs air.

Default Admittedly it doesn't answer that

...but it might be a game-changer for the OP if adding air to the tires didn't delay him and his passengers by "a good half-hour or more."

I did not say I have to remove pants to air the tires. The -10 has huge pants and with a straight stem as provided in the kit, you have to remove the front half to add air. I don't.

My pants have a 1 1/2" snap in cover, the tires a big red paint dot that lines up the stem with the opening when it is down, the tube is a 45 degree stem so it is horizontal, and an inflator with a 10" long extension and it is still a pita to add air.

I just want to monitor the inflation pressure easily so I can add air at my leisure, not under time pressure!

Default Portable Pump

This is a timely post.

I just ordered a portable pump, looks like a battery powered screwdriver. It arrives tomorrow.
