I USE to do what most of the others do. Was flying with a CFI that slapped my hand when I touched the flaps in my RV-6 because of it being a bad habit in a retract. I now NEVER touch anything till clear of the runway (except for opening the canopy on a HOT South West Summer day)
Mel is not the only guy that has a switch like that in a fixed gear airplane. I helped designed what Mel is talking about minus the horn to keep a friend in the habit for retracts. I gave him LEDs, resistors, switch, 9-volt battery clip, and Velcro to attach it to the airplane.
Yes I do call DOWN AND WELDED in the pattern. Boost pump, Gas, Undercarriage, Mixture, Prop (on short final)

What should I do? I am keeping my RV6A at home on my grass strip that is 1600' or so and I alway's have left my flap's down after touch down. From what I have been reading here I should put them up as soon as I touch the grass? That will not make my roll out longer on landing but shorter? I do have manual flaps and it seem's like as soon as I touch the grass I slow down pretty fast. I just started landing here at home this fall so I am new to this short field stuff. So I fell like I am doing pretty good but I keep telling myself it will be different in the summer with less lift.

The theory being expressed is that by raising the flaps, and killing some lift, you put more weight on the wheels. Which, on pavement, could be a factor. On grass, the "traction' is low to nonexistent (wet grass) but the trade out is the drag from the grass itself helps slow the airplane.

If you're making good landings on your grass strip now, don't worry about it, and don't change what works. But if you find (as I do) that slight bumps in the grass strip are enough to put you back in the pattern, you'll find that selecting flaps up as soon as you're established on the ground will keep you there.
Note: Don't select flaps up to try and fix a bad bounce... It'll just make the next one worse. Fix the bounce first, then when you're down smoothly bring the flaps up.

Considering I will probably never fly a RG airplane and raising the gear in a RG glider takes a LOT of work (swap flying hands, twist hard to unlock gear lever, pull gear up), I will happily continue to dump the flaps on landing when needed.

If the bump puts you "back in the pattern," you might want to rethink your approach speed.

I agree, and i'm working it down as time passes. My home circuit has a very tight turn on one end, and i'm leery of taking that too slow right now... I don't mind admitting that I need the extra margin because i'm not that good yet.

Rob,
Here is something that will give you a lot of confidence and safety when flying the tight, slow pattern:

This is a great way to reduce approach speed while insuring a margin of safety.

I land my 9A with full flaps and leave them fully extended for parking and tiedown. I use 10 degrees of flaps for takeoff. At the slow speed the 9s land, I don't feel raising the flaps to increase brake effectiveness is a concern.
Keeping the flaps down:
1. reduces the number of cycles on the flap motor
2. makes boarding the a/c much easier

It's all about approach and touch down speed....
I am a disciple of any type of AOA device for safe pattern work.
If the indicator is moving toward the no-fly zone I know more speed will be needed soon, the back pressure relaxed a bit in the turn and/or add power. It is the cats meow for making a minimum speed approach.
A few days ago it was 59 KIAS (well inside green AOA) across some tall trees and right on down to the flare point. Landed and made a turn off in 1500' minus about 600' to clear the trees and flare with very little braking. That will work only if touch down is at or near the 51 knot stall speed of my machine. No time to retract the flaps as they are electric so they stay at 40.
Most of the time I can't do it that short because of turbulence and/or cross wind, but once in a while in really smooth air, it is fun.
