Watarrow consultation

@Smile Khatri

  • Chatted w/ Watarrow members about wing constructions. Key points summarized below:

    • Moving away from monokote heat shrink wrap

      • Time consuming to manufacture

      • Decent amount of concaving w/ 1/16th ribs

      • Used non-CSA approved iron. The play might be to use team funds to procure it.

        • might use team funds

        • ask watarrow abt their iron and borrow it for the first run

    • 3D printed leading edge could be a problem - the ironing process could require about 200 deg C, which will probably melt/deform the 3D prints. Another option is to buy a bar of wood and CNC it to the shape.

      • another option is to not heat the leading edge, use glue instead

      • foam would still deform

      • make a small test piece w/ 3 ribs

Tracking Antenna

@Sohee Yoon

  • Angle Limiter update: Currently the resized angle limiter is being manufactured, and I’ll check it tomorrow (when it is finished)

Fuselage

@Sohee Yoon

  • @Calum Chisholm any updates on the new fuselage shape? Fuselage Design

  • How are we attaching the fuselage to the airframe?

Landing Gear

@Ben Lovegrove

  • Landing gear is progressing well Fixed wing landing gear

  • The front landing gear needs to be optimized for weight still which I will complete by the end of the weekend

    • The rear landing gear is nearly done, the hardware is all designed but I need to check the specs for the servo. I will also have this done by the end of the weekend.

Horizontal stabilizer
