When you pull power, be ready to land, NOW. Then apply braking, retract flaps and full aft stick on rollout. You can actually practice this approach at altitude as a confidence builder that it won't fall out from under you at 60MPH/full flaps. Your mileage may vary due to A/S indicators, rigging, etc. Practice slow flight at 2000' sometime with full flaps and get used to the AOA, feel of the controls and the sink rate. Also you can see the ball park power requirements at 60 and full flaps for a 200 fpm rate of descent. (Larry Vetterman assures me his VG's reduce all of my above numbers by 10 knots.) I haven't considered VG's as I don't like their looks and could only imagine trying to land on a heliport now...yikes! How much shorter could you ask out of a stock 180 MPH airplane with 22' wings?The RV4 is truly amazing. Another plug for manual flaps, if they failed to retract on an attempted go around, you could be in a world of hurt on a short strip with obstacles. SO...just don't go around on short strips! I have taught this approach to a couple of young F16/RV pilots who mastered it after one or two practice approaches.It also can be applied to 2000' strips with 50' approach end obstacles. It works!

It looks BEAUTIFUL. This prop reminds me of the high quality & low price we use to get from Pacesetter Props. Pacesetter is no longer in business but man did I love my old Pacesetter prop. The guy who made my new prop is Jay Anderson. He is very knowledgeable and willing to work with you to get a custom Prop that you will love. His prices are extremely fair (I got mine for about $500.oo including s your price may vary depending on what you want) and the delivery time was only about 6 weeks. For a custom made, quality Prop you can't beat that price with a stick. You can contact Jay at cloudcars99@yahoo.com or (325) 356-2810. His motto/slogan is "Quality Wood Propellers at Reasonable Prices". I'm a satisfied customer. **note: I get no discount, nor do I have any financial interest in this business.** We experimental builders & flyers should support small businesses that provide quality products & service at reasonable prices. That's why I'm sharing this hot tip with all the RV folks. If you call him, tell 'em Chuck says "Hi".

Thanks Arvil. I'm completely with you on the manual flaps and trim. My electric flap motor decided to make smoke one day, luckily I was on the ground watching it rather than smelling it on final! All manual for me from now on.

The main thing Bob, and Rob, were trying to point out is you are 4 times more likly to have problems with Elec/ Mechanical, flaps, and trim, then just Mechanical flaps, and trim , even tho a lot of people havent had eney problems, I prefer to reduce the ods as much as I can, Arvil Porter Scott Vanartsdalen wrote: > --> RV4-List message posted by: Scott Vanartsdalen > > Bob/Ray/others, > What speed do you use for short field approach? I did all kinds of short field work in my Champ and doggone one of these days I'm going to learn to slow my RV-4 down. I'd like a target airspeed to start with (at altitude) and see how it works then adjust it up or down for my plane. > > Thanks! > > Oldsfolks@aol.com wrote: > --> RV4-List message posted by: Oldsfolks@aol.com > > I have to agree with Rob Ray on the Manual flaps and trim.

All modern fighters use an AOA indicator in the Heads Up Display primarily for final approach and other flight parameters. Airspeed is a tertiary reference, we fly degrees of AOA. So when I discussed increasing my AOA, I meant angle of attack. You too can utilize this cool capability in any airplane now with the "bacon saver" AOA device and the fancier electric ones offered in Van's catalog. A wing will stall at a given AOA to the relative wind always, regardless of airspeed.
