RE: Hanger-9 Corsair ARF Mods for more Scale/ Accurate Appearance
True Turn is the first place to look for a prop hub.
This corsair is modelled after the WWII versions. If you are going with a 4 blade prop you will have to mod the cowl to have a lower chin or double side air scoops. The -4s and later were introduced in Korea.
The foam LX mjodel corsair with folding wings uses an 18 inch 3 blade prop in north am with a 270kv motor and elsewhere in the world it is sold with a 4 blade 18 inch prop on a 250kv motor.
The stock wheels are as big as you can go with the stock inserts. You could always cut away the sheeting and make up a square well and if you get adventurous you could make a set of doors. Look for a thread 'corsair gear doors'....
Good luck.
