    Valve Problem

    I dunno - seems pretty straightforward :) Without those cylinders blocking up the sides there's a lot of space. Yes I'm intentionally choosing steve henry's without a turbo/intercooler because that gets more complex. Seems like they're quite happy to use 582 like cooling setups. Not the most...

    Valve Problem

    Considered that yamaha phazer like marc's doing? :) Almost like a 582 but without the headaches and a bit more oomph.

    What do you think about "e-soaring"?

    https://global.yamaha-motor.com/news/2021/0412/ev-motor.html Anyone need a 496hp motor? :)

    My foam cutter

    Nichrome is actually locally sourced fairly easily. Vape shops all stock it for building coils. Believe my last 100' roll was about 10$.

    10/23 Raptor Video

    Shearing prop isn't necessary. The lines are made with the theory that attitude/failure may cause propeller entanglement. There's no reason to complicate unnecessarily. BRS, GRS and the smaller makers already account for this in the base design.

    Home Depot Plane

    Ok but let's make the distinction :) Dow blue/pink/XPS foam isn't bad choice in itself... Lots of aircraft use XPS - used smart (like skypup, rutan) and that's not a problem. The pvc is another issue 😂

    Home Depot Plane

    Largest jump in shipping costs (and also much slower eta) seems to happen when a dimension exceeds 1m (3ft2in+change). At least that's what I notice around here. This is why XPS/composite makes the most sense for a 'lower' cost build in my head. Although boku's recent carbon tubes purchase...

    Market for fork tailed doctor killers is probably bigger now than ever... Between security arrive 2 hours ahead + close contact risks during covid and reduced schedules...

    Can you please help me value a Christavia Mk4?

    With a subaru without glass... Headache of EAB - aircraft is basically worth the price of instruments and engine. Unfortunately factor in the eggenfellner factor... And you've got a very hard to sell set of steam guages when most are going glass... My .02$

    Mountain plane

    And people wonder why I still think a BRS is a good idea cutting across regularly. But it's pretty scenery.

    A solution looking for a problem

    Can you find me a nice step by step? 😂 Explosion formed wing ribs sound way better than press stamped wing ribs 🤠

    New Optional Task-based Phase 1 Flight Test Program for E-AB

    I've got 2 minds on this one... Task oriented is one thing. But part of it is still just burning off hours to prove the systems reliability. But then we have cases like Mr raptor - where it's clear he isn't running the cards just wants to burn off the countdown timer, and the systems are...

    Where to look for source of temporary electrical system failure?

    After checking the above. Have seen some wierd battery failures that came and went with heat/vibration/internal shorts.
