That could be the problem. I have a lot of rudder throw to hold top rudder doing point rolls and such. And my tail wheel is hard attached to the same push rod that moves the rudder.

In following video, I tried for 3-pointer landing. I am sure I did not hold any rudder. My left wheel did touch first. Since our runway slopes to the right a little if my wings were parallel to surface plane would drift to the right of centerline, I always touch down slightly left wing low to stay at centerline. Also I remember touching one wheel first helps keep Spit from bouncing.

Landing at 5:30

That video was cool and you're obviously a good pilot. Can you get someone to film a few of your landings? Maybe from the rear and focus on your rudder after you touch down. Three point landings are not a good idea, but that's just my opinion. more likely to get a bounce and certainly is letting the tail wheel contact with too much speed. I would try landing slower as well. These Spitfire gigantic wings will really let them float down to a nice slow touchdown speed. Not sure what else to recommend. Hope you can get it figured out.

Nice video! Not to take anything away from the Spitfire, but that Tomcat landing at 5:18ish was just spot on!

When positioning an electric motor you use the cross hair as the center point correct , like the pic shows

Really, really depends on the motor used.
The 50cc rimfire I used , the template did not work, nor were the box holes the same .

Ground clearance is a bit tight but is manageable as long as the strip isn't too rough.
