Started on the Hawk, my rudder servo opening needed to be cut (5 min job) and the rudder was loose so be careful when you remove the tape it doesn't fall on the floor! There is a brass/copper colored bubble wrapped wire which is probably for the hinge (it looks the same as the gear door hinge wire) but the diameter is smaller than the rudder hinge holes allowing a lot of slop so I replaced that with a larger diameter music wire for the rudder hinging. Someone earlier used CF rod which is light but wouldn't that wear over time?
We all have to keep after Dave to make more of those dummy flap hinge covers, no reason why he should have the only really cool looking Hawk I am way too lazy to mold them myself!
My buddies have told me to get it in the air first and then worry about the scale details. But some things are good to have, I got a Derjet cockpit and BVM pilot figure so I know where to mount things and how to adjust the CG. But Scale details like rabbit ears and hinge covers and repainted fins for stickers can wait until it is flying.
One last thing I will certainly install the wing fences and fuselage strakes before flying as they impact the flying qualities of the jet.
