I operated my gear today with the new struts installed. I didn't experience any issues, and cycled a few times without binding. Though I believe the wheel wells will need to be deepened a bit, as the retracts sounded like they were working harder at the last moment before stopping.
I'm guessing since the oleos are straight now vs the TLs having a slight rearward offset, the wheels are diggin into the wells a small amount.
Precisely the same thing I have. It is not binding, but yes, the wheel needs to go deeper than the stock wheel well wants to - which leads to the retract working hard as hell. I don't want to risk to burn the retract and potentially lose the plane - especially not with turbines.
The stock wheels don't have this issue for several reasons. Firstly, the geometry means the wheel hangs lower in the first place. Secondly, the trailing link with simply flex, masking any conflict between the retracted wheel and the wheel well.

And as a digression - the wheels don't turn while retracted on the stock mains neither - but whatever pressure/conflict there might be is completely absorbed by the trailing link allowing the wheel to flex as much as needed.Freewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion

Okay, so I managed to squeeze in flights 13-15 today between showers. A very big THANKS to Pilot Ryan for his video's of touch & go's! It was like night & day for me today!!! It has been said here before, and I'll say it again...one of the things I love about this hobby is the collaborative spirit everyone has toward each other. It is so gratifying to learn and grow as a pilot, and to benefit from the wisdom of others. Today I was impressed by how sensitive the plane is to a potential bounce, even at slower speed, but my landings were far more consistent at higher AOA, gentler, and I wasn't feeling panicked about the overall speed. I love it!! Too much funLOL Rob

Back from the field. Winds were stead at 13mph with ~17mph gusts today, and was directly across the runway. I had to re-CG the plane due to the cockpit mod and since my maiden had a Mobius camera taped to the tail for some in-flight footage. Balanced at 86mm, but the plane felt very tail-heavy in the air and was dragging the tail really badly. Landed the plane and took it back up with 78mm CG. Kept the flight short since I am still familiarizing myself with the plane, and kept the gear down since i haven't yet modified the wheelpods and didnt want to risk a gear deployment failure.
This plane can take the wind surprisingly well, though I will probably enable my lemon Rx gyro to deal with any wind buffeting and not mess with my landing approaches. With my scale thrust nozzles installed I count tell any pitch-coupling, however I didnt really fly over 3/4 throttle and didn't try jamming the throttle either. A big thanks to Dlxpkg2000 for CG assistance and acting as co-pilot. His Arctic Thunder Hawg is also nicely done if you haven't yet seen it.
Here is a video of today's second flight after going from 86 to 78mm CG. Landed with take-off/ half flaps due to the heavy crosswinds. I also cut down the nose oleo spring by 3/8" as recommended by TI. I ran short on time to print a mobius mount to attach to a hardpoint, so a wide FOV hatcam video is all I got :-P

DD, Congrats on the day. Look forward to more flight reports. Can you estimate the weight of the cockpit mod? Just curious. Best, ElbeeI solemnly swear to "over-celebrate" the smallest of victories.~Lucky B*st*rd~

Had a pretty stout cross wind that gave us a bit of a challenge. Well, check it out and see for yourselves!

Surprising results on the CG aspect, but whatever works works!
She should drag the tail a little during high bank turns (in which case manual rudder input should be considered mandatory - just like it is for fullsize aircraft), but she should certainly not sag the tail in level flight - even when low speed. She shouldn't drop the nose neither for that matter.Freewing A-10 turbine conversion: http://fb.me/FreewingA10TurbineConversion
