    Willis,  The brakes holding static runup depend on two things:  1.  The size of tires - Larger tires usually require double-puck brakes.  2.  The power and thrust of the engine and prop - 912 engines have more than the 582 engines.  And, I will add - 3. The geometry of the pedal to brake connections makes a huge difference in braking power.  Most guys who have had a problem have modified their master cylinder to pedal link to get a 2.5:1 mechanical leverage, such as Matco describes in one of their posts on their site.  Hope this helps.  EDMO

    Cant see $1150 plus shipping for electric trim larger elevators - You could modify yours for less than $100 including all parts needed.  EDMO

    That sounds like a bargain price for a Model 5 Kit.  BTW: The yellow Avid Speedwing on ebay just sold for $9700.  EDMO

    I think my wood formers were used as kindling wood after they got broken in the fall from the trailer.  I modified the right side for a big baggage compartment and welded in the front part of the former in the process.  I totally forgot about the former on the left side and on the bottom until after blasting and painting, but I will figure something out.  
    I scratch-built my cabin widening too, as well as about 99% of the rest of the plane - TWICE! 
    I cant see paying $1150 plus shipping for larger elevators with electric trim, when you can modify yours for probably less than about $50, or at least under $100 in parts and tubing!
    BTW:  Jim,  my Cabelos boat seats are 16" wide, so that two of them fit inside the 32" wide cockpit bottom - my butt has to fit in that space!  ;<)  EDMO

    Doug,  as you can see in the photos of Jim Chuk's widened fuselage, the first standoff was not lengthened.  My only concern about lengthening the first standoff is that the stringer might interfere with the struts when folding the wings.  I would just bend the new stringer a little if needed to match the old standoff.  I haven't checked all of this to see if it would matter.  Thanks for the opinion.  EDMO

    Although the rib tails were judged by Avid and Kitfox to be strong enough, when the kits were evaluated in the UK the British authorities demanded that the extra braces be put on each side of the tails to meet their (like FAA part 23) standards.  Numerous rib tails have been broken, mostly in accidents/incidents here in the U.S., so some reinforcement before covering is considered a good mod, but not mandatory here.   EDMO

    My max weight in my prime was around 200 - normal average 170-180 - Now 160, and 1" shorter at 66":  My seats are about 6" or 10" more higher than the original Kitfox seats - I can get my old bones out of these easier and have a lot better visibility over the nose.  I raised my wings up 6".   Thanks,  I think?  ;<)  EDMO

    I didn't stretch mine, although I am using a Subaru EA-81 with Tri-gear.  I did extend the leading edge of my wing about 4" and modified the undercamber Eppler ribs to modified Riblett ribs like the Kitfox 4 and later use to hopefully get past the 90 mph wall that the undercambered wings seem to hit.  Also enlarged tailfeathers a LOT.  I am also changing flaperons to separate flaps and differential ailerons with separate controls.  Those changes add lots of time to building.  EDMO

    Since I didn't double the bottom tube, mine tapers from the middle of the V at the rear down to the original tube at the bottom of the door opening.  EDMO

    I think if you will just study the double-tubes in the photos at the rear and bottom of the door it should be clear.  This is a home-brewed project.  Just make sure your doors fit before and after welding.  I had to bend my doors at the rear middle because I didn't put the double tubes at the bottom like Jim did.  EDMO

    Thanks Jim.  I've got a little welding to do anyway, so will probably go with steel.  Was just wondering about aluminum.  I think I could rivet a triangle brace to the extension cross tube I welded in between the old and new points and it would support stringer whichever material I use.  EDMO

    If there is ANY mousepiss corrosion on the spars, it will have to be cleaned and neutralized, and decide if replacement is necessary.  EDMO

    Jim,  I wasn't smart as you to put the double tube at the bottom of the door, so I had to bend my doors to make up for the extra 3" width on each side.  Question:  And my memory of part name just left me - The middle tube that runs from the door center to the tail, and was wood on the original Kitfox - Do you think that an aluminum tube would be strong enough for that, or use steel?  I forgot to weld mine on the left side.  EDMO

    Hint - get the one with the round platform (table) - It measures in grams for mixing glue, ounces for other stuff, and pounds - not the British $ kind  ;<)  It says the platform (table) can be removed for cleaning, but I cut a round paper plate the right size and it keeps the glue off of the table.  It will also weigh your container (tare) and reset to zero to measure the glue.  $19.99  EDMO

    If your W/S or Skylight need replacing, give some thought about doing it in 2 pieces, and use a dark tinted material for the Skylight.  EDMO
