Hi everyone... Just to report for precaution to beef up your wing tubes.
A few days ago hideki noguchi's plane on his second flight had a wing tube failure in flight. No abrupt manuever was made,he was just clicking some up trim and it just folded on the root then crashed to the ground. Good thing nobody got hit.

Im trying to obtain videos to prove that no undue stress was given to the plane.
Im posting this to call attention of the manufacturer and for mb owners to increase the thickness of their wing tubes or fill the tube with light balsa to prevent tube collapse.

Its such a great flying airplane which i witnessed the maiden flight here in the philippines. Second flight was done in done in tokyo japan where it was brought by the owner.

Japanese rc pilot was a carden aircraft tournament winner with more than 30 years in rc experience.

the stock wing tubes are weak .. be it either the hollow or webbed ones. I use a piece or square aluminum stock jammed into the round wing tube at center through around 60% of the tubes span/length on mine and its super tough ... 1.5 lbs weight gain however , and the tube holds great. I do like to pull some Gs , which i would not dare do on the stock tube ..
