RE: Shorts Tucano T1-120
Pisandro, The quality is standard Nitro, not the best, not the worst. I am using Spring Air retracts with oleo struts. I have the main gears from a mustang that I cut down to size by 3/4". the Mustang gear is 85 degrees which will be vertical on the Tucano due to rake of dihedral. The nose gear has been ordered from spring Air. I actually stopped at Spring Air on my way back from Florida to Atlanta and met with Bill Waddon the owner. I showed him the fiberglass fuse and he agreed that the quality is good. Should get the nose gear this week. I removed all of the covering due to paint peeling from the covering. I have recovered with light gray Ultra Cote.
The Ultra Cote color is close to the pre-finished gray on the fuse but I felt it was not enuf of a match so I am having the fuse repainted by a club member who is in the auto collision/repainting business.
I am going to use a separate servo for the steering of the nose gear and will mount it, as well as the servo for the throttle, forward of the wing tube. I will use a reversing "Y" harness or I will criss-cross the cables if I can. The alternate locations of these servos eliminates the pushrods and wiring running through the fuse cavity where you attach the wing bolts. I could not get my hand into the fuse cavity to insert and tighten the wing bolts with the config suggested. Also I could not tighten the wings sufficiently snug to the fuse with the nylon wing bolts provided, one stripped. I replaced the blind nuts with SAE 1/4-20 and steel bolts-problem solved. I also had to ream the holes in the fuse slightly to accept the wing alignment rods.
You will need to cut a 1/16" deep cavity in the bottom of the flaps to accept the bottom plate of the supplied control horn so that it sits nearly flush with the bottom of the flap. I used a liberal amount of CA to harden the cavity. Also, I could not get the rudder and elevator servos to align with any of the holes in the formers aft of the servos. I opted to install carbon fiber pushrods, one for the rudder and one for the elevator. (I will be joining the two halves of the elevs). In order to get the pushrod outlets in the rear fuse close to the stab I had to criss-cross the rods by installing the elev servo higher than the rudd servo. I made my own guides for the pushrods. I have Nitro's Extra 500 now three years old and it flies great, but it is a relatively light airplane. The weight of the Tucano gives me some concern. the fuse in not too bad but the wings, ailes, rudd and elevs are heavier balsa than I would prefer. I have had no reply from Nitro regarding the incidence on the stab, so I will assume the design is correct and keep going.
