    Hi Dave,

                   Been going through this blog since I found it and thought I'd ask a question if you don't mind (& given your mechanical skills) - and the question is this; Why does everyone cut the VW engine to make a boxer twin? i.e. Why not just remove the cylinder heads from one side, block up the holes, re-balance & fire it up as an inline twin? . . Something to do with the angle of the dangle on the crankshaft?

    Also I noticed you've widened the top of the air-frame where the wings attach (which looks Much betterer :-) but haven't added any diagonal bracing to the rectangle/squares formed in the  mod. I know there are a few designs that don't but have also noticed a lot of designs that Do - And given that your wings attach there, there may be some twisting forces (yaw) from potential wind gusts to account for???

    It may seem odd that I can't get my head around the first question yet can still make the second observation but the firing order in my head is a bit orf from months of study on other topics.

    BTW I'm not a mechanical engineer, just an old phart with a lifelong interest in aircraft - I'm more of an electronics/IT/computing bod . . .

    Would love to build one of these if I can set aside the time & money but am rather less sure of my building skills & Oz is chock full of regulations compared to the US. 

    At any rate thanks for posting this series - I've learned a lot from reading through it and I wish you all the best with getting it done . . . 

    Oh and P.S. - I may have some ideas for Homefire around the Arduino stuff if he is interested??

    Homefire  Is always  open  and available when it comes to Brain Food.  


    **   The Idea of the two apposed cylinders versus the Inline  is both Esthetics and Machismo.  The Firing order and  Piston Positions come to play.  Would be like trying to ride a Three Hump Camel.  The third Hump under your butt.

  2. Wind:   Well Any one out braving this junk ?   Stupid wind ripped a sheet of siding off my mobile home the other day.   That's cool, I had $35.00 burning a hole in my pocket.  Just needed to drive 50 miles  each way to pick up a couple of sheets. Funny enough it was nice and calm winds  on the drive .   LOL As long as you was driving WITH the WINDS !   Dang stuff went  up again.   $28.00 a sheet now. 

     Eaaa Dave,    Good time to test your wings.   No Engine Required.   Just Tether the plane to your Go Cart and  Up Up and Away,    eaaaa?  Weather Liars  say the wind was hitting 28MPH.   My little hand held Anemometer said 58MPH ...     Since  I was taking the reading Leaning about 45 Degrees into the wind I have faith in those reading.    Dang Weather Peoples.  LIE LIE LIE. 

    Well here I am Cold as Ell again. Yesterday I could have the front door open for a bit. Watching the Quail Eat. Every time the darn wind comes from the East it's flipping cold here. Hope the Caravan folks are as cold as I am. 

    My Wind Turbine Generator would have been Tested to the MAX if had if finished and up in the air. 

    Click on the Link for a Cool Active Wind Map. Click your location to zoom in. Kinda Mesmerizing it is.



  3. Still working on E-Bike Battery Packs and Wind Generator and Two Metal Detector Projects and Solar Power Wall Project and BangGood through me for a Loop. They messed up my order of Silicon Wire needed for the Battery Packs   and sent these crazy small Quad Drone Motors in error. They have no interest in me sending them back to China and Already Reshipped the Wire I needed. Now I need to figure out how to do a Remote Control Plane or something using these four motors ? LOL I have a Air Hog helicopter that Could stick on of these on. Stay Tuned !  I looked these up on BangGood and are replacement motors for a Mini Done going for $70 - $200 a pop.  These sell for about $10.00 ea.  I can get Props for the things for $3.00.  Someone at BangGood's going to get a spanking over this one.  

      Dave your Battery Pack is in the mix as well.  Still gathering yet more parts.

  4. Most of those Chines Engine are unmarked 66cc.   Listed as 80cc the chines include the Combustion chamber in they're calculations.   Pop that head off, Replace the Head Gasket and torque down .  

    Is the ex-host port like 40mm or 32 ?? 

    A good rule of thumb is to shoot for 8mm head bolts @ 120 to 140 inch pounds. For all other engine fasteners, 6mm, set your torque wrench to 60 to 80 inch pounds. Those values will keep you out of trouble.  ""

    Replacement Parts can be had DIRT Cheap for the things.
