It was time to install the battery and ignition to the sides of the motor box. I am getting ready to route wires, install the throttle and choke servos, and finalize the front end of the plane before I get the canister installation under way, so this was the first step. I like to see my parts bins empty out, it means were closer to being airborne!

I simply held up the battery and ignition module where I thought they should be located and marked where the holes for the Velcro should be drilled. I chose self wrapping Velcro over zip ties for a few reasons:

1. Vibration -- zip ties are hard and easily transfer vibration to whatever they are touching
2. Ease of installation -- the self wrapping Velcro is simple to route through the holes and pull the foam in for a good solid fit
3. Ease of removal -- the Velcro can be easily removed to service the battery or the ignition module
4. Good looks -- red Velcro matches the red trim on the DA-50R, so it was a natural choice
5. Flexibility -- Velcro is somewhat flexible, unlike a zip tie, and won't just snap...I'll be able to see the wear starting and replace the strap as necessary

Those nice straps can be found at Home Depot. I found black straps at Walmart.
