Left hand side E-scale 004 airbrake. I bought a set as I needed a right handed replacement. Glider now sold so I’d much rather someone gets some use out of this than it continues to sit in my parts locker!
Far nicer than the similar-looking (but much inferior) Hobbyking ones, this Escale version has properly potted / protected motor and electronics and far greater reliability.
Only $30. Collection Adelaide welcome, or can post Australia-wide for around $5.
