Overview


Project proposal

  • Design and modify the EXI 450 main frame using SolidWorks to better suit the needs of modern hobbyists

Total Parts=60

Project Proposal


Liquidworks design process

Each team member of Team LiquidWorks was given at least two parts to create using SolidWorks.

The Design Tree to the left shows the steps used in order to create the part shown above.

LiquidWorks Design Process


Design process continued

As we can see, first the basic sketch is created followed by the revolve feature to create the part. Then another sketch is created and the cut-extrude feature is the used to complete the part.

Modifications implemented by team liquidworks

Lithium Battery-Used in RC Helicopters

Dimensions-138.93mm * 36.08mm * 38.00mm

Battery Tray-Used to support the battery on the EXI 450

Dimensions-54.66mm * 25.85mm * 6.00mm

Modifications Implemented by Team LiquidWorks


Battery tray modification

Battery Tray is too short to hold most conventional lithium batteries used in RC products.

Allows for batteries to be strapped on more securely

New Battery Tray that is nearly double in length

Battery Tray Modification


Upper frame modifications

.48 in * .15in Access slots were created to make mounting hardware on the inside of the model easier

Screws extremely hard to reach on the inside when mounting hardware

Upper Frame Modifications


Group member responsibilities

Group Member Responsibilities


Design challenges

Difficulties

  • Extremely small components

  • Precision cut parts

  • Built to be a precise flying model

  • Some parts were no more than .03 inches thick

  • Parts are made to be compatible (lots of holes)

Solution= Hours of staring at a computer screen and Calipers

Design Challenges


Conclusions

LiquidWorks

  • Created a 3D Model of the EXI 450

  • Created a set of working drawings-

    (Assembly, Exploded Assembly, 2D Drawings)

  • Modified the Upper Frame and Battery Tray

  • End Result Provides Adequate Representation and Successfully Displays the Efforts and Ideas of Team LiquidWorks

  • Things to do Differently-Pick a More Simple Project

Conclusions
