Mine is doing ok. Looks like the air stream helps keep it on. As is this plane can't seem to do violent aerobatics that could make it fly off. Check the magnets for a parallel fit and scrape any glue off the faces. The closer they fit the stronger.

I finally think I have a nice damped nosewheel shock absorber design. I was going to machine it from aluminum but think I can do it with some plywood and two wing bolt brackets to save weight. I found a ball point pen spring with the perfect tension, next I need to work the air damping out. Soon, no more of that nose bounce-tail smack on rough ground. Or at least less of it.

So far, all looks good. Was just a little worried about the small magnets, but will try as it came out of the box.
Have now beefed up the front wheel bulkhead with some hardwood, put some glassfibre on the motormount and put a separat steering servo with metal gears in it. Hope this will do it...

I have been doing ok with one HXT900 experimental nose servo. It is doing well and I have a metal gear servo on the way. Just don't land on the nose wheel but you all know how that goes.

I can warn you strongly, if there are any bumps of 3/4 inch or more, CG any farther back than 50mm will make the tail slam down hard and scuff the rudder. Then if you have any speed, it may jump up and fly again, stall, drag a wingtip then cartwheel. Be sure to force full down elevator as soon as the nosewheel touches. Not much time, so hope if not too fast, then as soon as it touches the ground.

Don't put so much concern for this plane, it's the game. Worry too much because it's beautiful , panick, and make a bad move. Above all do not loose your flying speed low to the ground. This plane (mine), has a sudden wing dropping stall.

Spend more than half of your first flight trying to fly it slowly, like landing speed.

Thanks for the advice, will keep this in mind. As this is not my first one, all will be good. At least I hope so... Have beefed up the fuselage quite a bit and reglued everything.

One more thing, if you strike the prop, it will probably loosen the motor glue. When a long time of bad weather comes, I will drill through the front ring behind the prop spinner and thread for 2-56 screws to hold the motor mount in better. They need to be flathead so the motor can go over them.

Have already put a glassfibre ring in front of the motormount and reglued from the inside with epoxy with mixed-in chopped glassfibre. That should do it

SR-22 Landing Gear Upgrade

Has anyone here added larger wheels to the nose and main gear of this airplane?

My nose near isnt that strong on grass.

I talked to Great Planes, they said this plane is obviously meant for improved runways. My studies show for flying off grass it needs an air damped nosewheel spring and soft air filled tires. I am now in progress and will be working on the nose wheel shock absorber. I had planned a similar one before I found the above link to a spring nose wheel at Hobby Lobby, it is not air damped and needs the damper to complete it. The Hobby Lobby one is for a .30 plane and probably too big, another reason to make my own.

link and a little more studies at at post 280

I plan on removing the wheel fairings and replacing all wheels with larger tires.
I did take off somehow but on landing the nose gear bent in and the motor shaft snapped off with the propellor still attached.

The front servo area of the nose gear is weak and the wire gear isnt strong enough.

A paved runway would work for takeoff. My club has grass like most clubs and ground handling is not very good with this airplane if its rough.

I'm trying to get to this nose wheel shock for us, I have been having an avalanche of problems lately.

Sorry to hear about the damage, but I do think it is plenty strong for some fairly hard landings, keep that nose up and plant it on the mains only. If you stall it and it hits nose wheel first, especially on rough fields, the nose wheel can dig in and snag.

I saw a full scale Cirrus flying today, ran in and got the binos. It was tricky to see the difference between the GP Cirrus and the full scale one, this model is accurate.
