Re: Wheel alignment...a photo tutorial
I wonder if the gear was misaligned that badly to begin with or by the "test" flying and multiple ground loops?
Checking the alignment is a great idea. However, IMO, if a new set of Grove gear is out that far, it should be sent back to Robby Grove for reworking on his dime.

This friend was the fourth owner so hard to know what happened. I've never had to adjust a new set of grove gear.
Re: Wheel alignment...a photo tutorial
Just did my gear alignment. It’s bang on straight. Is this ok or do I need to add some toe in or out?
Re: Wheel alignment...a photo tutorial
Mine was the same as yours and I didn't do anything. I have been happy with how it handles.
Re: Wheel alignment...a photo tutorial
Did you guys check yours in the 3-point attitude, or level? Level, mine was straight also. Rotating down to the 3-point I had 1 deg. of toe-in due to the camber in the Grove gear. Toe-in with a taildragger is de-stabilizing, and causes more tire wear than neutral alignment of course. I figured that 99% of the ground miles would be in the 3-point attitude, so I shimmed neutral for that, and now when rotating to level it's close to 1 deg. toe-out (which is actually stabilizing with a taildragger). The airplane is just a little better handling now... it's a subtle perception, but a fact in my case. I used a 1/2 deg. shim on each wheel. FWIW.

Interesting John, I had done it in the level position. Tomorrow I'll go back to the hangar and see what it says in three point
Re: Wheel alignment...a photo tutorial
I also aded shims and noticed a significant difference is stability on landing particularly.

Re: Wheel alignment...a photo tutorial
Toe out Ross? Was it straight before you added shims?
Re: Wheel alignment...a photo tutorial
No Josh - it was for camber. It used to sit with the bottom of the tire closer to centre line than the top ( I forget if this is neg. or positive !?) and the outside of the tires wore more than the rest (26" Airstreaks). Now they wear evenly and it feels more stable on landing.
I did the alignment for toe in/out before first flight and it didnt need any adjustments for that.
Getting close now Josh - and it looks a monster!
Best of luck.

Re: Wheel alignment...a photo tutorial
Thanks for posting this tutorial T J. After a few landings in my recently purchased model 2 with my instructor we knew something was bad wrong. It would make some un-commanded turns to the right and rudder was ineffective at keeping it running down the runway in a straight line. I performed the alignment, had a 3/8" toe in on left main and a 3/8" negative camber. I bent the axle until I had both at 0". I also learned the Maule tailwheel was unlocking with full left rudder so I replaced the tail wheel with a new Matco 8" pneumatic wide tailwheel. My tail spring was also bent so I replaced with the new 3 spring version which after installation, I realized the spring was canted to the right. We built a shim to correct the spring and installed it on top of spring. All 3 things, alignment, tailwheel and spring mounting was causing the aircraft to turn right. Now that all of that has been corrected, it is WAY easier to control. I solo'd shortly after correcting these issues.
