WING TUBE CRACK
I have been flying a 42% DALTON for almost a year, not too many flights though.
This week end I noticed a crack in the main wing tube. Fortunately I saw it on time, and the airplane has never hard-landed, not crashed, only snaps on IMAC routines, and the tube properly handled.
I have been asking about it and what I have heard is really scary as the consensus is "probably a bad batch tube" !!
I also noticed that this tube has a very thin wall too. This is the original tube shipped when I bought the kit from Dalton Aviation.
The questions are:
1. Are there thicker tubes available ?
2. Dalton: Why not using a bigger diameter tube ? The moment of inertia should be higher for this size of airplanes. Some smaller airplanes have bigger diameter tubes!!!
3. What about aluminum tubes ? I heard that they bend in regular flying, which proves that the stress is gigantic. Is it true they bend?
Thanks for your inputs on this!
