Another detail that some might find trivial... but as many hawk owners will know. The outer gear doors on a hawk main U/C can be a major ache to the nether regions. I have had hawks with various systems of actuating these small doors. Ranging from Elastic bands, to thin wires and springs. All with various levels of success and failure. FEJ have chosen to go with a pre fitted tiny air cylinder thats slaved to the main and nose doors. Testing during the build showed it to work perfectly, but I guess the real test will be in the field. ALl I can say is that it was a nice change to not have to waste hours of my life fiddling about with some half cocked means of making them work. Throughout the build, I found little touches such as this which really helped speed the build process along. Which if we are honest is exactly what we are looking for when we buy an ARf jet...... right ?
