I've purchased the baffle kit from Vans. The plans for the oil cooler show a spacer on the aft side of the left side rear baffle flange. The baffle kit drawings show a reinforcing angle on the forward side of the same aft left baffle. The parts list states that the reinforcing angle is 3/4"x3/4 angle - but the supplied material is 3/4" x 1.00". The rear flange on the baffle is 1.00". If I fit the angle with the one inch side flush with the one inch rear flange, I have NO edge distance for the screw holding the baffle to the engine case. If I reverse the angle, the 3/4" flange gives very limited edge distance for hte nutplates installed on that flange. Has any one else had this problem? Which way did you orient the angle? Do I really need both the reinforcement angle and the spacer - I'm not sure what function the spacer is performing? The Positec cooler is wider than the standard Harrison/Stewart Warner cooler, which also makes it difficult to fit in this area - can any one give me any tips? Thanks Shirley Harding RV6 QB Baffled!

The HS spar flange won't help the original poster because his problem is that the elevator horn is hitting the rear bulkhead before it hits the elevator stop. I had the same issue but on my airplane it hit the bulkhead at exactly the right elevator travel so I got lucky. Richard was not so lucky and will have to trim the elevator horn to get the right travel. You will find as you progress through the process that the plans become less and less useful. Van's did not anticipate every single little problem than any builder is ever going to have. Sometimes you have to trust your own judgement, or the judgement of others or simply call Van's.

(The small Positech does just fine for me here in the local climate - which is usually cool if not downright cold.) I used the spacer at the aft LH corner of the baffle set on the argument that this would add a bit of extra "beef" at the join and also for the outboard row of bolts holding cooler itself as they pass through this area. I placed the angle doubler with the 1.00" flange running fore and aft although this required trimming the flange to clear the #4 cylinder valve cover. I assume the "screw into the case" you mention is the one which threads into the aft side of the #4 cylinder adjacent to the valve cover. I used the supplied rectangular doubler here as well so this screw passes through three thicknesses of material (rect. doubler, the 1.00" flange of the angle, and the basic side baffle). There is not a lot of room here for the cooler especially with a -320 which is 1/2" or so narrower than a -360. My cooler thus had a problem moving in far enough to get decent airflow through the back baffle without rubbing on one of the engine mount tubes. Thus I ended up grinding a half circle out of the inner aft mounting flange on the cooler to clear the tube. This allowed the oil cooler to move inwards about 3/4" which made a big difference in how it all worked out. (This flange on the cooler doesn't do anything so no loss here). A picture will probably be worth more than any additional words so have a look at: http://www.vansairforce.org/projects/okej/onephoto.cgi?Picture_0015.jpg or go to http://www.vansairforce.org/projects/okej/ and scroll about halfway down - click to enlarge the picture.

You need to take it apart and bend the frame narrower until it springs to the right width. Leave the tracks alone once you have them parallel, and adjust on the frame. Some builders cut the frame and cut or bend the pieces individually, then weld it back together. I didn't have to do that, but I may have gotten a better fit if I had. There is an issue of the RVator about a year ago which was devoted to the slider. Someone else may remember exactly which one it was. It would probably help you to review it. Hang in there. It took me maybe two weeks just to get the frame and canopy fit. The better job you do here, the better and easier it is to get the skirts to fit and look good.

I now have 2 flying slider RV6's, and after much cussing, et.al, I now have two canopies that slide themselves open past the first 8 inches. The 1st thing is to absolutely get the front bow to shape. That may mean some bending, maybe the use of a torch or something. I just put one of those ratcheting straps across the bottom of the bow and cranked until it was right. Next, make sure the rails are at the appropriate spot outboard. Moving them too far outboard will cause problems with the side skirts later, so be careful about moving them too far outboard. Make sure the canopy frame slides nicely before you put the plexi on, if it doesn't, it only gets worse when you put the plexi on. In fact, I would try to bend the frame slightly inboard a bit too much, as the weight of the plexi and it's effort try to push the frame open somewhat, exaserbating any rubbing tendencies you may have had before installing the plexi. Also, gently chamfer the outboard side of the plastic rollers to the shape of the rail and make sure you have the right amount of spacers between the mouting ear and the roller, that will keep the screw head from rubbing the rail. You may have to fiddle with that as well. Last but not least, to make for a really nice, smooth opening, I have put a strip of teflon tape in the inside of the rail. That way if the roller rubs, it still slides nicely. Both mine were extreme pains in the rear, but with some time they now work great. Both of my canopies slide by themselves and the skirts fit like gloves! Hope this helps, Stein.

I spent a lot of time with them developing a way to check without disassembly. The article is in one of the past Experimenters in my safety column. Basically, it involves loosening the bolts holding out pad so one can pump the piston out. If you see the o-ring within about a 1/10 of an inch, it is in back wards. No fluid is lost, and no disassembly is necessary unless you find that the piston has been installed incorrectly. There have been several reports of the backward piston coming out far enough to leak all the brake fluid. This happens when the pads wear enough in about 300 hours and it dumps the brake fluid. O-rings can't do the job when one assumes that the factory installed the piston correctly.

MIL-H-83282 (synthetic, flash point ~240 deg C) replaced MIL-H-5606 for all but civilian aircraft use in the '50s after they got fed up having too many military aircraft brake fires. It is usable with Viton seals. You all are grownups and can decide for yourselves whether the first case is the preferred situation.

The Trench is a fairly straight valley running from Mackenzie (near 55N 123W) to Watson Lake on the Alaska Highway, approximately 360 N.M. The floor of the trench is 2-3000' msl with 7-8000' mountains along each side. It is a frequently used flight way but with very limited facilities and emergency strips. George in Langley
