UPDATE TITLE
Include any updates here + reasoning
Tricycle vs tail dragger
leaning towards tail dragger, gives prop clearance and easier to mount to the frame
tail dragger risk of tipping?
landing will be more flat
tail dragger good
spring steel to absorb shock
about the same price as shock absorbers.
springs easier to maintain, specs are available
pneumatic shocks? probably stick with spring shocks
spring shock can’t be tuned easily
start off w aluminum

Initial Design
Implementing tail dragger design, two wheels at front one at tail
This will give prop more clearance as it is tilted back
Using aluminum sheet metal with bends to absorb energy
Aluminum was chosen as it is light weight and meets design specs with the lowest safety factor being about 3 when stationary
The design uses the bends to also help create a more stable place
Front landing gear bend out to give wider base of support
Back landing gear goes straight back to try and keep the centre as in line with the CoG as possible
