I've just finished building the seagull 90 size super tucano..

Yeah to be honest its quite solid, not too bad a copy of the original and has lots of nice touches.. but at the same time has some really weird things going on.
As said before, the manual is more of a reference guide.. I really used it to get measurements and to check I was using the right screws at the right moment... little else.
In this model the fuel tank is WAY inside the fuselage and impossible to access and wiring the ignition and tank in place was horrible!!
I also had to go online to find photos of the original plane as it came with NO images to indicate where the stickers should be placed...
Also it has(had, I went for servo-less retracts) a system where only 1 servo was used for all 3 retracts and you had to disconnect push rods every time you take the wing off.. just seems mental!

BUT its come with dummy external fuel tanks and missiles, pilots and seats etc and looks really solid.
Mine was even wrongly delivered to another location then re-posted, the box had taken a real beating but the plane was fine!

Maiden on saturday.... looking forward to it! First model with flaps and retracts!
