Martin, I have been reading your build posts with interest. I have not owned a Bi-plane model previously and I am on the brink of purchasing this model.
The mods you have made certainly improve the scale appearance, particularly the inter-plane struts. In fact looking back at the manufacturers photos it is hard to believe they supply those huge box section monstrosities !! I too would have to source some stream lined tube, just as you did, and fabricate new items.
The question I have for you concerns the flying wires. Are these actually required for structural purposes or are they just for scale appearance ? I ask because without doubt the scale arrangement for the wires you have chosen, is a definite improvement in terms of aesthetics. However, is there a risk of structural break up in flight, due to this new arrangement ?
(Please forgive me if the answer to my question is obvious to the more knowledgeable builder).
Regards, Dave
