I have MS Flight Sim X ,any idea how it compares. I have a CH701 for it but when you put realism to full its un-flyable, so I use a Savannah model instead. :( Guess It works out the same. How is the 701 in X Plane? Kevin -------- Mark Twain: Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines.

I've run off the left side of the runway a couple of times. If you find out what is causing it, let us know.

I've tried a number of times to do a nearly zero power approach and never get a reasonable landing. I don't mind the firm arrival so much as my plane's tendency to yaw to the left right at touchdown. I looked at the "flywithgus.com" video and noticed that his firm landing was also accompanied by a left turn. > > Because of the nose high approach attitude (even with flaps down) I've thought about approaching from left of centerline so that when I do hit the runway I'll be about straight. I do the shortest landings (under control) with speed of about 45-50 at the threshold. Any slower and I'm am very nose high and lots of left yaw. Much faster and I use too much runway (actually there are often no runways, just small clearings). > > Have others noticed this, or is my plane just a bit out of sorts in this configuration? -------- Tommy Walker Read this topic online here: http://forums.matronics.com/viewtopic.php?p=187125#187125 ________________________________ Message 3 _____________________________________ Time: 07:34:52 AM PST US Subject: Zenith701801-List: Re: Installing cabin top plastic From: ruruny@aol.com Craig, The plans are light. Not alot of info at all. Leave the protective cover on. I layed it on top of the fuse and traced out sides, I cut to the inside of this line for a perfect fit. I cut the rear for good rivet clearance and edge distances. The front edge will overlap the frame so you will have a decent edge distance for riveting.Do not drill front untill you install windshield. I did all cuts on the workbench using a straight edge and scoring it a few times?with a utility knife. I then folded down the cut for a clean break. If it doesn't fold fairly easy, score it again. Once cut, I started drilling in place. I taped it so it wouldn't move, marked a line and drilled using a fan as used in the pictures. If you search the archives in the old zenith list for ruruny, you will find lots of advice from other builders on this install, windshield etc. One question that was never answered and never in the plans was the rivets on the gusset, and the tube connections at the front of the frame.?Whether to drill and rivet thru these. I just let the lexan lay on top of these rivets as I felt the lexan is not part of the structure(see pics again). http://www.701builder.com/00fuselagehome.htm The brace goes on the diagonal by drilling to diagonal first using a right angle drill. I trimed the bottom of the brace even with diagonal. Clecoed it on to diagonal, took covering off lexan, clecoed lexan down and drilled down thru lexan thru brace.

I always land with no power, and about half the time there is a definite yaw to the left just at touchdown. My no flap landings approach at 60, and pull power at the threshold. Most are ok, but if I hold it off to a very slow airspeed, it yaws left. My flap down landings approach at 50 with no power, and are pretty steep - almost floating - angle. Ground run is very short, but if I hold it off too long, I get the left yaw there too. When I try it at altitude, slowing to almost nothing, it doesn't happen. I thought I was the only one, and blamed it on the wind coming out of the canyon on the left side of the runway.

Certainly not a 172, but far better then a Kolb or other large winged lightly loaded ultralight type airplane. Surprisingly easy to land in a cross wind too. When you get on the ground though the cross wind will want to skid you sideways pretty easily if it is strong. Keep the upwind wing down with the flaperons. > > -------- > Ron Lee > Tucson, Arizona > > This weekend I took my 701 up in 20 mph winds and on crosswind landing I let it drift me sideways.

When the nose is high at touchdown it moves the gear forward quite a bit. Any asymmetry in either the weight distribution or the gear could cause a turning tendency that is mechanical rather than aerodynamic in its origin. I am going to try to get my wife to film some landings from directly in front of the plane as I land to see if I can determine what is happening.
