Mike,

Just happend on this thread, I'm just completing the build of my Laser 3D and will probably remove the wing tips based on the comments.
Beware that engine mount / firewall. On my first in-plane test of my new OS52FS, the firewall detached on one side! I have reinforced the engine mount to the firewall with triangular fillet throughout but I'm still scared it will disintegrate in the air.
Do you have a view on the best way to connect the tailwheel to the rudder so as to ensure that both don't get ripped off in a heavy landing?
Also I am not happy with the amount of 'throw' on the rudder using the suggested closed loop arrangement, I'm tempted to replace with a single pushrod?

Regards
Frank
