Default RE: Hangar 9 30cc P-47 Build Thread

The next step was to install the main gear retracts. I am using the new Robart Electric units. These are available through your local hobby shop, Horizon Hobby, or Robart. The cool thing about these is there is nothing to do but bolt them in place. The model is designed around the pneumatic retracts as they have been the main stay of the industry for so many years. As we know air lines are a pain to secure in a wheel well for the most part. Hangar 9 has designed in some cool little brackets that capture and hold the air lines out of the way. You never have to worry about air lines getting caught up on a wheel, etc when the gear is up. For the electric installation, we used a dremel tool to open up these mini bulkheads so the wires could fit through and be held out of the way for the installation.

pic #1 shows the two holes for air line retention on the root rib designed into the kit.
pic #2 shows the holes in the mini bulkheads inside the wheel well to keep the air lines out of the way of the landing gear when retracted.
pic #3 shows the dremel tool being used with a small grinding bit to open up the holes into a slot for the wires.
pic #4 shows the mini bulkheads all opened up to hold the wires.
pic #5 shows the main unit ready to bolt in with the bolts next to it and some blue threadlock.
