Rob / others - this was a really useful email in terms of what you would build if you were doing it over. Today I got to thinking what would you do differently. (For instance do any aspects of the U/C become loose over time and you wished you had used taper bolts in the first place?) Just trying to make sure I get it as near to right first time as possible.



Thanks, Steve.

Hi Steve,

     Haven't had any issues with the u/c bolts so far. I replaced all my control surface hardware at 1000 hours. Showed very little wear but I lubricate them regularly with LPS 2. (sold in several places including Acft Spruce). The one thing I do have is cracks in the lower rudder skins between the rivets, none so far on the elevator. Rather than make a new rudder out of .020, I stopdrilled the cracks and used HySol and a round .016 patch clamped on overnight over the area. Once the HySol cured, it looks bulletproof. I can always make a rudder later, too busy flying it right now...Van's sells .020 skins for the RV4 control surfaces pre-bent...

    Someday when Van's has forgotten the RV4 completely and all he sells is (trainers) 7A and 9A and 10's, (which is getting close by looking at completions), I may try to buy the rights to the RV4 and make a pre-drilled and quickbuild kit...just thinking out loud...

  Good Luck!

Thanks Rob. I'll just do what the book says then. I went the 020 skins as 

you advised although I have the standard forward fuse skins. I am waiting 

for the XP-320 to be announced - not long now - and will put a 2 blade MT 

on. It sounds as though the way the -4 bolts together is pretty well 

debugged. The nosedragger -7 & 9  that is certainlty not the case. Lots of 

problems with the nosewheel - both the bolting together and the design. On 

soft ground its an accident waiting to happen. Boring to fly though even if 

quick.



My mail was prompted by the Rocket construction notes where I saw all sorts 

of assembly issues causing a problem in later life (the aeroplanes) and 

thought I should enquire at this stage. I guess it is lighter and therefore 

less hard on itself.



One thing which I find ugly on the -4 is the way the shoulder PAX seat belts 

attach to the upper skin. The -9 and I presume 6 and 8 approach seems 

better. But I am going the standard route.



A couple of questions. Do you think it is acceptable to put a little door in 

the foot step F-428 to keep small loose articles in? Is this sometimes done? 

Also, what is your thought about putting the PAX 5th harness point around 

the flap drive. There was a picture of that on VAF last week.



Cheers, Steve.

Anyone responding to that fuel tank pick-uptube/b-nut safety wiring bulletin 

on Van's website? I looked at it real hard and talked to my local A&P. He 

though it was nuts. There are B-nuts all over the AC that never seem to go 

bad. Plus you'll potentially do more damage to the tank lid tyring to get 

the sealer and gasket off to retrofit. Try as you might to clean it up 

you'll get little flecks of sealer floating in your fuel for years.

Steve, I too thought the Van's fuel tank AD was a CYA forage into the ridiculous. No I didn't cut into my fuel tank and I know for a fact I don't plan to... 

  Hmmmmm, reminds me of the inspection AD they published right after the RV8 demonstrator had a wing fall off...

Let me know if that happens.  Would be really interested in a quick build of 

one of the sexiest planes ever the RV-4.
