    Getting to the fuel filter?

    I move all of them on the first hose change to up behind the EFIS. If people can't get to it easily they tend to never check them. Behind the EFIS you pop the panel, use a screwdriver and it's in your hand.

    Max rpm or?

    Good point. variable pitch vs constant speed.

    Getting to the fuel filter?

    I have only seen one fuel filter ever in a CT that had any real amount of debris in the fuel filter and even then it didn't affect the fuel flow. I guarantee this isn't a fuel filter issue because it has the wrong symptoms, but you can check it if you want. The only way this could be a clogged fuel filter is if you have been dumping garbage fuel in your tanks. My guess is you haven't. The non Rotax AI's are going to lead you down the wrong path. This isn't a Continental or Lycoming. It's either down behind the lower center panel back near the firewall and if someone was smart they relocated it up behind the EFIS on the pilot side. If it's behind the center panel it's a royal PITA to get to, remove and re-install.

    Max rpm or?

    But you don't want a set point where WOT is ever lower than 5500 rpm. Higher is good.

    She won’t start?

    Just pop them off and send them to Lockwood if you want to be sure.

    Max rpm or?

    Flying at WOT at anything under is over pitching. Flying at 5200 WOT is really over pitching. It will cost you fuel and like you mentioned unnecessary stress on engine parts. You will also loose speed because the prop is less efficient and thee engine doesn't have the torque and HP to do a good job turning it at that low an rpm at WOT.

    She won’t start?

    The absolute first thing is to rule out a poor battery EVEN if you think it is okay because your human ear can not tell the difference between a few rpms that will start vs not start. Jump it from a good battery. Jumping a battery is free and easy so do it. Once you know the battery is good and it still won't start place a 1 gallon baggy of ice around the ignition modules. Don't make it too full because you will want to wrap this around your ignition modules on top of the engine. Let it sit for about 30 minutes and try to start again. If it cranks right over buy new ignition modules. You can if you like send the modules you have into Lockwood and have them tested if you want.

    Max rpm or?

    With your prop I would cruise somewhere between 5200 - 5500 rpm. Look at your fuel usage and see when you increase the rpm if the speed vs fuel is worth the extra rpm. It is kind of a personal thing.

    Tubes

    Get them from Desser tire on line. These are 6.00 x 6 tubes. Get heavy duty butyl tubes with the 90 degree stem which is called a T87 stem.. You can ask them to balance tires you buy. make sure you ALWAYS balance your tires after you mount them on your wheel. I have NEVER seen a tire in balance without weights. https://www.desser.com/Aircraft-Tires-and-Tubes/15-600-6-AERO-CLASSIC-INLEAKGUARD-IN-BUTYL-TUBE-AERO-CLASS-GL-1587.asp Looks like our president's tariffs has driven prices up by about $20 per tube. Wow They used to be around $40 a tube.

    Two More Failed Ignition Modules

    I cut two open with a bansaw, but it does destroy the modules. Brute force doesn't work. To my knowledge they use a chemical to dissolve the potting. You could always use a new and old module together you just couldn't hook up the soft start feature on the new one.

    Two More Failed Ignition Modules

    "The result is both modules failed." I'm trying hard not to say it, but what the hec, Told you so. 😎 ☺️ The reason why is one failed a while back and you didn't notice because the other was doing the starting. Then eventually the other failed. This is normal. Most would never know that one failed until the second died to. Seeing both fail is what most people report. It's been all over the internet in different forums even Rotax - Owner. Rarely do people notice one.

    Tell me about Decalin

    Decalin. What is it and why use it. http://www.materials-base.com/product/decalin-runup-fuel-additive

    Tantalizing new engines

    Just to throw out some fun stuff Rotax is now working on a 916 engine rated at 180 HP and a new 6 cyl. rated up somewhere around 240 hp. The new 6 cyl. is only longer by one cyl. length over the 912, but I think we're looking at years down the road for the 6.

    Tantalizing new engines

    the 915 is out performing the 0-360 so far.

    Tantalizing new engines

    Definitely not LSA. Pretty soon in a few Rotax will be everywhere and with the new technology over the old Continental's and Lycoming's they will storm the market. Water cooled, fuel injected and turbo. Who would want a loose tolerance, oil using, magneto, need major work before TBO engine, not to mention an engine 100+ lbs lighter.

    Generator whining over intercom

    The capacitor is up above the battery and just behind the square engine mount tubing. It probably has some fire sleeve over it and two wires coming out off the end. Two wire ties hold it in place. I carry them if you need one. They aren't expensive. I have found a few with broken connectors at the base of the capacitor. These are polarity sensitive so make sure the right wire goes back on the right terminal. If you swap them as soon as the engine starts up it will fry it.

    Rotax Upgrade to iS?

    Not feasible. Too many air frame mods would have to be done.

    Sorry, but no and no.

    Need a new door seal 2007 CTSW

    When I put on my new door seal many years ago on my SW the door was hard to close and it had that front gap up on the leading front edge of the door that let cold air in. I unscrewed the door hinges and just relocated the screw holes out just a tad and forward. The door plate in the top frame has a steel strip in it. So I put some JB Weld in the old holes. Tapped the new holes and my door was then a perfect fit. No more leaky air and easy to close.

    A couple questions

    I'm sure that would work. You can buy regular silicone paste at Ace Aviation. I use the same thing on the door locking pins. Keeps the pins and the fuselage from excessive wear and makes the door work much smoother.

    A couple questions

    Silicone paste will stay in place and not run off or dissipate. The paste is thicker so it has more staying power. WD40 and some other lubes may fog your window if over sprayed too often.

    Max rpm or?

    If that 5170 rpm is WOT then that prop is way over pitched and can actually cause damage. There are zero redeeming qualities on over pitching and you loose all descent flight characteristics.

    A couple questions

    Look here. ttps://wingsandwheels.com/catalogsearch/result/?q=Windows+mecaplex I use a tad of silicone paste on the rails. This keeps the plastic from grinding itself down. makes them slide smoothly without any wear. I have been doing this for 11 years and has worked well.

    prop covers

    What Tom said. My wife made me some. They are easy to sew.
