Add a 2mm carbon rod to strengthen the long push rod. This largely increase the precision on high speed roll and loop.
Very strong Easterly monsoon today. Gust almost 40 kph.
Only my Eurofighter and F35 lightning can fly safely.
My F35 EDF suddenly squirl noisily and glide safely. Found the EDF migrated forward (due to the strong static thrust) and hence the blade touch the deformed fan duct.
Learned a good lesson that foamy glue may not be safe enough (especially there is no screw/ press lock to hold the removable fan bay)
