St. Dysan... I get Xoar Sword 22X10 props from Valley View RC (
www.valleyviewrc.com) pre-drilled for my DLE's (no charge for that). I always buy an extra just in case...
no added weight and it balances perfect with the starter... although I have the ignition for the DLE on the plate that's fitted to the engine standoffs with zip ties, the ignition battery is mounted on the plate immediately forward the tail feather servos below the cockpit (there's a cool plate there ready for Velcro - so I have two 2S 2200 MAh batteries and the rcvr there). The starter motor switch is where the air retract valve would mount, and I have Robart electric gear controller double stick taped to the wing itself. The 3S 2200 MAh battery is mounted on top of the fuel cell and velcro'd below the holes the wing slides into.
