I went ahead and bought four. I needed to replace some ones I've used. Amazon used to be a place to buy them, but the prices have all gone up.

Rotax 912 Annual & 100 Hour Enhanced Service Class Expanded Inspection & Service Class Instructor: Roger Lee in Tucson, AZ (This is a private class and not a Rotax certified class) This is a two day class. Dates: May 4th & 5th, 2024 Saturday & Sunday (0800 hrs. – 1700 hrs) Cost: $450 Do to the hands on work a maximum class size is 10-12. Pre-registration is needed because classes are usually full. Phone: 520-349-7056 or Email: roger@lsamechanic.com Location: Ryan Airfield in Tucson, AZ Due to a big demand this class is back. Prepare to learn and have fun doing it! This is an improved service level class that will raise and improve the 100 hour and annual inspection understanding. It will guide people to perform at a higher level of education and knowledge base whether you are a private owner or a mechanic. After discussions and feedback with the students that have taken this enhanced Service class with mostly hands on instruction they feel like they are capable of performing at a higher level with inspections, performing simple service work and documenting in the logbook over some other service classes. This class will have a couple hours of classroom each day, but the majority of each day is all hands on work with a functioning Rotax 912ULS and a 912iS engine and targeting the 100 hour / annual inspection and general service work. We will perform an actual annual inspection on a functional aircraft and every student will be supplied with an inspection checklist. We will demonstrate and perform other service functions. While working you will be able to ask real time questions and take notes to help your understanding of the work when you return home. This will empower owners and mechanics to perform better 100 hour and annual inspections, better DOCUMENTATION, and service-based maintenance on the 912 engines. This class will expand on the already successful Rotax Service class by incorporating more hands on time, but more importantly it will expand on better logbook documentation and will focus on a more detailed and proper inspection process while performing service-level work on the 912 UL, ULS & iS class engine and the 914 engine. This enhanced class will help reduce maintenance induced engine problems and simple time consuming inquiries to the Rotax distributors’ and owners’ maintenance based questions. The new Expanded Inspection Service Class and associated demonstrations will include, but not be limited to: Classroom instruction: each day is 3-4 hours of classroom with engine part props (Each student to bring a laptop, IPAD or similar media device) 1. Registering engines 2. Finding current manuals on the different internet sites 3. How to use each manual and its content 4.

All Ace Hardwares are different. Some are small and some are big. Mine here on 22nd & Kolb may be the largest in the US. Page,AZ has a small one. You have to check each one out individually. If you saw mine you'd be shocked. They took over a whole shopping center.

Buying a CTSW! Looking for CFI or ferry pilot

Coppercity a.k.a. Eric Swisher right here on the forum. He lives in Bisbee, AZ and he does flight training and transition time. -
You haven't seen my Ace that is a half block long and a full shopping center. It has stuff people haven't ever seen. When I want to research or invent something I walk the isles and can put a project together in my head then buy the parts. My Ace has more stuff than many hardware stores put together have. Even my smaller Ace is huge. I can find stuff at these I can't get anywhere else. I buy all my hardware there except for AN stuff.
-
Instead of trying to find something on a computer and order it and pay shipping you can use the same info at your local Ace Hardware. They have the same stuff. These nuts and bolts are from another world. They are everyday common items.
-
Ace Aviation (Ace Hardware) will have them. There is nothing special about these. Just match what you have. These nuts & bolts are not aircraft only hardware. I buy most of my metric stuff from Ace. We have some huge Ace stores here in town. One Ace here is like a full shopping center.

This issue is why I lube the two flap rods in the baggage compartment every annual. I put enough liquid lube on each rod and as it runs down the rod I run the flaps all the way up and down to help spread the lube. It keeps dry metal to metal stress down. It isn't a cure all, but it certainly seems to help.

Typically the "standard" green color is changed every 2-3 years. The orange DexCool orange "extended life" is usually good till the 5 year rubber change.

This cost just a few bucks to make. I've been using it 20 years. This is 1" angle iron. The two holes at the top are for the bolts that attach to the gearbox. The two bolts at the bottom are no so tight the two sides can't move. Then hop over to Harbor Freight and buy a slide hammer. that goes through another hole in the bottom rail. I have seen some make a slide hammer. You just need an all thread long bolt, two large nuts and a 5 lbs weight lifting dumbbell. Ace Aviation (Ace hardware LOL) has all the parts.

Good, budget retirement locations for a CT pilot.
Roger Lee replied to Eddie Cesnalis's topic in Random Thoughts
Ryan Airfield on the west side of Tucson. This is where I work too. Easy to move around in and easy to fly around because we have so much open country. -
The external generator will not fit under a CT cowling and the pulley up front for the belt won't work either.

Immigration isn't an issue here. We are 75 miles north of the border, but they don't come here. They are headed for other areas in the US. So you never hear or see them. No smog, lower housing and cost of living than California. Plus less traffic depending on where you live. I don't care for Phoenix because of all the people. We have good weather more than most places in the US and that's why we have so many training facilities here and so many large aircraft storage areas. I like the outdoors and with so much open land you can do about anything you want. -
You forgot air temp effect on burning. It's not about flow here for the original post. It's about outside air temps. If an engine gets nice cool dry air vs hot humid air which fuel mixture will burn better? This was part of the original question. It was about cold air temps.m Plus even with our carbs they can only adjust so much and then it's more about air pressure not temps..
