Default Sideslipping an RV

Being fairly new to RVs and the proud owner of an RV-7, I've not been able to get a consistent answer as to whether there are any restrictions or limitations on sideslipping on base or final to loose height. It's been suggested to me that it shouldn't be done, and/or shouldn't be done with any flap out. I'm not referring to a sideslip in the flare or short final in a crosswind, but something more sustained and likely at a (slightly) higher speed.
Any advice or guidance would be appreciated!

I sideslip my -6 frequently with full flaps all the way to the flare. I'm generally at 1.3x stall speed when I begin to come out of the slip. I've never experienced any adverse characteristics, and when I transition trained with Mike Seager (the factory transition CFI), he indicated that the RV-6 slipped very well and we practiced a few. An RV-7 could be different, but I doubt it.

Why not experiment at altitude to check the handling characteristics of your -7 with flaps, without flaps, and at different bank angles and speeds?

Who suggested that you not slip an RV? What reason did they give? How much RV time did they have? Did they ever try it themselves?

I used to slip my RV-4 all the time with full flaps as well as clean. Never paid attention to the speed in the slip, though, as my attention was outside. I slip the -9A when I have to, but slips don't do as much in the -9A as they do in other planes.

Kyle's got the right idea, go try it at altitude. Personally, I doubt you'd spin it, but that might happen, so go find an RV instructor and have at it!

And please post your results!

I use to do nearly full control deflection slips in my cessna. I've slipped my 7A a few times although nothing even close to the control deflections I did with the cessna. When slipping the 7A, I didn't notice any unusual characteristics.

I have found slips in my rv are far less effective than the cessnas and pipers ive flown. Even with full rudder it just isnt that effective to me.

My 9A does not bleed energy nearly as well in a full slip as the 172, but with full flaps and a CS prop I really haven't needed it other than Phase I testing.

Built an off-plan 9A with too much fuel and too much HP. Should drop dead any minute now.

With a Constant Speed prop, the slipping is not always necessary BUT when one flys formation, sometimes it is needed. Over the past 20-years flying and more than 3,300 hours in my RV-6, I have slipped the aircraft MANY times including full rudder inputs. Very controllable and very similar to the 1XX series Cessnas but easier in the RV.

Default Itís hard

It’s really hard to slip an RV at cruise speeds. That big rudder is really hard to push out into the wind. I have pressed on it at cruise, never hard enough to endure a true slip.

Another RV-4 slipper here. I do it all the time with flaps down; I like remaining high until the runway's made.

Slips aren't as effective in an RV as factory planes simply because there's less, and cleaner, side area to add drag. Not *as* effective, but still effective.

Try flying a -9 with a FP prop, you will learn to slip it. Although, as Ed said above, in the -9(A), it really doesn't do a whole lot.
