    Pre-emptively helicoil aluminum bolt holes?

    Figured I'd ask but after watching a Project Farm video its seemed clear that a helicoil insert makes bolt holes in Al much stronger. Would this be a smart move for head bolts? Only thing i can think of is the Al expansion might losen the insert, but from the tests done in the video it...

    Mods should not post as mods unless moderating.

    Its a small point but if a person is posting thier personal opinion they should have an account to do so. If a mod shows up in a thread then its assumed that something is going on that requires a mod. And that can sour the tone and direction of a topic. Just my $0.02

    Start stop technology

    Not sure if i fully understand this but It seems that start stop tech has basically made electric pumps standard for car motors. When stopped, the engines have oil and water pumps to cool the engine while in stop mode. Is this true? I know BMWs have had electric water pumps, but it seems...

    Lack of twin engine E/ABs

    Anyone have a good reason why there are almost no multi engine E/ABs? Iirc FARs don't forbid it and they are not overly complicated. Someone did slap a second motor on an RV and it seems to be going well.

    Hiring an engineer to do the maths

    Has anyone hired an engineer to do some structural mods on an experimental? What was the process? What did you have to already have done? Was the process fairly straightforward or was it a hot mess?

    Are map stitching errors in EFBs common?

    I use FlyQ for VFR and am noticing a few graphic issues with sectionals, specifically when two sections appear to be stitched together. I emailed FlyQ and they simply said yes, oh well. Anyone else seeing stitch/sectonal errors in the EFB they use?

    EAA 3DExperience.. worth it or not?

    I just deleted the old copy of solidworks I had via the EAA. Has anyone actually used the 3DExperince suite? It is worth the money? Is it useable over an LTE tethered connection or do I need 100Mbps to make it useful? I have the option to get Solidworks Student Edition for $99, the EAA...

    Goodyear wheels and brakes

    I inhereted some Goodyear brakes and wheels (with very good tires and tubes). One caliper needs replaced and service info is lacking. So far, these brakes seems to be despised, and brake linings are $250 per wheel. So dump them? Make them work (via ebay)? Can they be salvaged in any way?

    Mitigating corrosion from moisture in wood

    Took apart an aileron that uses wooden ribs (3 wood ribs 7in long 2.5in tall 1 in thick) and they are bolted to a 1in OD 2024-t3 torque tube. There was corrosion (pitting) under every rib, enough to reject one tube. Since the plans don't address it, what can I do to mitigate the corrosion...

    The EAA builders site is laughable bad.

    I've had a few emails back and forth with the EAA tech dir about how bad the security of their site is. I mean its crap. So more proof.... I make an account on the eaa builders website. It requires a ton of stuff that should be simply copied over from my EAA membership, or better yet, just...

    Substitute Red Oak for Mahogany?

    The flaps/ailerons of my Bede lists Mahogany as the the material for some ribs. The ribs are 1x7x2 in a symmetrical teardrop shape with a 1in hole for the torque tube. There are a total of 8 ribs. The Janke scale lists Red Oak at 1250lbf but multiple Mahogany species from 830lbs up to...

    Round number for heat treatment?

    Before I call up the company's I have found I wanted to get a general idea of what the cost of heat treating a -O aluminum alloy to the -T3 state. Anyone have any small projects done (ie wing ribs)? I know I can form the 2024-T3 around a form, but I think It will be much easier if I did all...

    how much bondo?

    Im looking at my BD's flat surfaces and the previous owners did quite a bit of bondo work. Almost every rivet row has bondo and I am seriously tempted to rip it off and 'do it right' (or try to). Do factory planes get bondo or is the stamping of parts good enough to not require the pink stuff...

    Anyone here pick the Garmin GI275 over the uAvionics AV30?

    They appear to be offering the same features, but the GI275 seems to a Garmin only/mostly ecosystem while the uAvionics appears to more readily support anything that adheres to standard IO specs. I like that the AV30 is more a 'build your own custom system' vs the GI275 is 'here are your...

    rebuilding stabilator: reskin and spar that has been drilled

    I inherited a stabilator that has some poor workmanship. I want to reskin. What are my options to reuse the main and trailing spars? They are blind riveted. Should I try and replicate the holes from the spar onto the new skin or simply move a safe distance over? Not worried about the...
