We got maybe 10 rpm drop. We changed it out to about a 10" long muff fitted over on of the crossover pipes and got much better results. That said, I've never needed carb heat on our O-320, although I do use a little bit when aggressively leaning to aid with atomization.

At some of the airports I've flown to, one in particular I'm met with a line guy wanting to kick the thick yellow chocks into my wheelpants, but eventually brings it back to the tailwheel. I've seen some plastic wedges advertised along with metal angle, but wondered if anyone's found the item to be the ideal thing for the RV.

I spent 15 years in the USAF in aircraft structural repair and have made literally hundreds of hyd, fuel, & air lines from aluminum and stainless steel .... i have also seen most of the conditions i have described here... (not the welded fuel lines, though...NOBODY does that) ....hope this is educational enough for you!

Nevertheless, as others have already pointed out, this is a good way to add weight and expense without addning much real benefit.

Pick whatever size ABS pipe that will fit under your wheel pants. Buy two Ls and two caps and a 10 ft section of the pipe. Cut to size to make a U that fits your tire tightly. I have I think 1.5" pipe, and no 6X6 tire is going to jump it. Locks wheel in place. One on each main will stop even a tail dragger from wagging its tail in the wind. BTDT.

The tire rolls on to the chock base and prevents it from skidding. Also like the way they nest together for storage. I use only one set on the nose wheel.

I made up some 3/4 in PVC pipe chocks that have worked very well for me for going on four years now. With two Ls and two caps, make up a U shaped chock for each wheel. The spanwise legs are about eight inches long and make the chordwise leg so that they fit a little snug to the tire. There is a little trick to removing them that you will quickly pick up on. They are light. very effective and cheap, what more can you ask for. -- Harry Crosby RV-6 N16CX, flying - 443 hours -------------- Original message ---------------------- From: davidbf@centurytel.net > > I'm wondering what RVers are doing for wheel chocks when parking on a ramp.
