Hi at all

A little bit surprised while mounting the rudder to the fin.
The drillholes are not alligned to the drillholes in the rudder. After i added some 4mm plywood with 5mm holes to shorten the distance between for the hinge mounting between rudder and fin, i find out the drill holes are not correct alligned. The two middle ones have a deviation of app. 3 mm. Originally the rudder fitted, probably the wide distance between fin and rudder allowed that, but now if have to sand out an oval hole for a correct alignment of the rudder. Hopefully the fixation with 2K glue comes well.

The carbon tube of the rudder is not correct mounted in the middle of the rudder. Deviation of 1.5 mm. At the moment i have no idea how this affect the flight line, because the small metall one in the front of the rudder is exacteley in the middle of the rudder. Correction is not possible, or i have to remove the passtube in the fuselage, remove the carbon tube of the fin and replace everything to correct them.

My youngest boy suprised me with the ultimate servo fixation :-)
Heavy Grade Airplane Aluminium and only 48 grams. For the screws he inserted self locked heli coils into the aluminium to have more resistance for the screws.
This Fixation will placed on a plywood plate in the wings for flaps and aileron. Total additional weight of servo mounting and plywood plate and and stabilizers 59 grams. Not too bad ..., or :-)
The L-Shape Aluminium hasn't had really my certification for high power servos :-). Pictures of the wing mounting will come later on.
Rudder Horns and reinforcements for the landing gear from Sandor arrived today and the complete Illumination of Optotronix too.

Kind regards
Rainer
