For most of the other airplanes I have flown, the landings go like this: The mains gently kiss the runway, chrip chirp, and the nosewheel is held off and gently and slowly comes down as the energy dissipates. (Ok, that happens some of the time). When I land my 701, the mains touch down more or less gently, but the nosewheel immediately plunks down. The closest I have come to being able to hold the nosewheel off is to hold 3,000 RPM (with an 80hp rotax) all the way down final, and this gives me enough energy to hold the nosewheel off. This seems like a lot of power to carry into the flare. Is the three wheel plunkdown just the way it is? Is there something wrong with my rigging (incidence of horizontal stabilizer, etc)? I do have vortex generators on the elevator. I do not have a forward CG at all, as I have a BRS in the baggage compartment and a rotax up front. Does anyone have any tips? I am thinking of installing an angle of attack indicator to more precisely control things in the landing.

This will give you a bit more energy to use during the flair. You didn't mention what you were using as an approach speed. Take this with a grain of salt though as I am basing this on general light plane expirience and not on specific 701 expirience as I am currently still building and have zero hours in a 701. The Angle of Attack indicator or Lift Reserve Indicator would probably be a big help in this situation.

It must the geometry of the airframe to landing gear placement. My 801 does the same thing,, for short landing I carry alot of power, keep it nose high and as slow as I feel safe for the wind conditions and just expect the nose wheel to hit rather firmly... The current fix is the reverse the ma in gear and that puts the rear wheels farther forward making it less pro ne to slam the nose down but in the 801,s case you have to notch the gea r to fit the attach bracket. If I reverse mine I would have to elongate those notches and that is something I don't want to do.

I have landed in some grass strips that are far from Golf course quality :-) and in the roll out or "fasterly" taxi the front wheel bounces... Could hit the tail if was more light loaded. In the time I have flying ours (me about 80 of the total hours, others are my brothers) We have developed an instinctive way to hold the nose wheel up at roll out and then gentle let it go when the elevator is loosing force, most of the times it does not bounce, but on the other side, some of the bounces of the front wheel are capable of ashame me in front of pilots :-) Saludos Gary Gower.
