List, I am getting the urge to build an  RV-4 to set next to my RV6-A in the hanger. Since I want to build this one  as reasonable as possible orphaned kits are a good option.

                  I have located a 1989 Tail Kit with very little done at an excellent price.  Question for RV-4 Builders: Are the 1989 kits less advanced than the newer ones?  RV-4 kits appear to have made fewer advances.......pre drilled skins....QB, etc?  Any reason other than corrosion to stay away from the 1989 tail  kit? 

                                                                                                                                                                                Thanks, Tom in Ohio

The original RV-4 kits were not & are not available in QB, pre-punched,  pre-marked, pre-aligned, pre-anything, no jigs required....in other words. YOU  measure, build, drill, jig, alignment line, one step up from plans built. Since  you have a 6A, think about a HRII Rocket. Ya take some -4 parts, some parts from  John Harmon, invest in a 540 Lyco as we did and build an HRII for about the same  price as a -4. But you get an RV-4 on steroids. Since the RV-10 the price of  540's has gone up. When we build the Rocket they were cheaper than a IO-360. I  assume you have ridden in both the -4 & an HRII.....if not do so as soon as  possible. Is the HRII harder to build than a -4 ?..Yes, a little, but well  worth the extra work. Too bad your in Ohio or we would give a ride in N561FS.  I'm going to post on the Rocket list so watch your e-mail, someone near ya'll  may offer you a ride. I assume you built the -6A so an HRII is just more of the  same and "Mo Better".

Tom:

 

 My RV-4 was a little newer (bought the tail kit in 1991) but I don’t think there has been any change over the years to the basic kit (no predrilled skins).  One item that I would recommend is that you use .020 thick aluminum skins.  The original kit came with .016 thick skins.  I originally built mine with the .016 skins and developed cracks at the stiffener rivet holes after 40 hours.  I rebuilt both elevators and the rudder with .020 skins (which Van will supply) and also added one stiffener in each panel by decreasing the stiffener spacing (fortunately I did all this before painting).  I know have 365 hours on the airplane and all is well.

 The biggest problem with the tail kit is that it often times leads to a  wing kit!  But seriously I think you'd be fine with it. You might want to  go with the thicker skins on the rudder & elevators.

Actually a HRII is what I have in mind! Several people on the  list have advised me to go with .020 Skins on the elevators and rudder  which sounds like a good plan.

                                                                                                                                                                     Thanks, Tom in Ohio (10G-Holmes County)

Seems to be the major recommendation....thicker  skins.

I understand that several HRII's are flying with the slightly larger RV-8  tail feathers. I have no personal knowledge on that but I'm sure there are HRII  drivers out there that will respond.   KABONG  Do Not  Archive
