There’s no debate: back pressure always reduces engine performance and is not needed. But I can’t say if losing the flame cones makes a meaningful performance difference here.

We use the CEP earbuds plus full helmets at work. They’re good at blocking turbine helo noises and letting the coms come in clean.

I’m a huge fan of mine. Buy the higher option one, even if you’re not sure you’re going to add all the features. It’s cheap enough to buy transducers after the fact to add features in later. The extra money buys you a pigtail (F5, I think) that can only be added at the factory. I used a VDO...

I’ve got some 4 pulse whelen strobes that I love. I thought about switching to LEDs but never saw anything that seemed as eye-catching.

No issues with this one. Charges my iPad while the screen is on. No radio noise, either. Car Charger, Anker Quick Charge... https://www.amazon.com/dp/B01K9MQ8WW?ref=ppx_pop_mob_ap_share

I have no direct experience (yet?) but I had a long talk with my FSDO. The annual program letter (which isn’t approved or disapproved by the FAA, just received and filed) spells out the operations for your E-E aircraft. That includes any events you’re going to exhibition at and proficiency...

I’d imagine with that much flap that you’d be good with a smaller fish-mouth angle. When you deploy the flaps the effective chord line of the wing changes and it’ll change the angle between the wing and floats. I’m super interested to hear what the experts think!

https://www.aircraftspruce.com/catalog/inpages/garmin_gi275eis.php https://www.aircraftspruce.com/catalog/inpages/eicgr30p10-05345.php They honestly look pretty similar to me. I guess the difference would be in Garmin’s ability to be more than one display, but if it’s your primary engine...

Yeah, agreed on the complexity - that’s why I’d plan a quick-build kit! For me though that decision point is a number of years away. My kids won’t even get to college for another 15/17 years or so.

That’s good to hear, actually. I just did a short oil change after a long period of inactivity and I was shocked how dark that oil with only ~6 hours on it was. Looked much worse in the sample jar than it did on the dipstick. You just eased my mind a bit!

No worries! And no thanks, I think if I build it’ll be a 4 or 5 place in a kit. I like putting stuff together but I like flying, too. A QB kit costs more but would get me flying a lot faster.

Have you thought about the Bearhawk line?

I’m not trying it for any power gain. In automotive race applications folks are playing a game of cumulative small gains. I’m just sick of wiping up oil from everything whenever I remove the cowl. Plus I like to tinker. This was fairly cheap to play with.

I ordered one last night as well

I think you’re the one that told me about the marine stabil! I haven’t used it in the plane though. Around the time I was ready to try, the 91 e0 prices near me climbed to within a few cents of 100LL at the cheapest airport so I started running a gas again. At the current prices, I need to...

I had massive noise issues: alternator, strobes, heck even the wig-wags chimed in. Rewired (shielded!) my whole ics system and it’s as quiet as a Catholic Church now. I repeat the recommendation to get a hold of the wiring diagrams and re-wire appropriately. Then you can happily cruise to...

I don’t have any scientific evidence, but my limited experience for the folks storing semi-bulk mogas is that marine sta-bil works pretty good for a year or so. The red stuff didn’t last as long in my motorcycle (the addition of kids to our house made that thing a lot more stationary than it...

Mike’s got a great point. Small addition from my nobody self: shooting firearms is a perishable skill. Just like any other physical activity. I might could have run for 5 miles straight two years ago, but if I haven’t done it in a while I shouldn’t count on still being able to.

I think all (or at least a high majority) of EFI systems use return-style fuel systems. My understanding is that helps maintain consistent fuel pressure all injectors and helps with hot starting.
