Description

Simulated wheel
Replace the sticker from the kit with a more realistic part. Print two laying on the back with supports. 

Float support
The stock wingtip float supports have two issues, they are too long and they don't put the right angle on the floats. I've recreated the OEM version for anyone that needs a replacement. I've also made an improved version that is shorter and has a 4deg angle built in plus some streamlining to reduce drag. The stock floats are cut in half then glued onto the new support. SCAD files are included if any changes are needed. 

Water spray rails
The hull angle isn't aggressive enough which leads to bad spray control. These rails add a more downward angle to the edges of the hull to help keep water away from the props. Printed with a .12 layer height for a smoother profile. 

Water rudder stub
Used in place of the stock water rudder when flying on grass. The stock water rudder sticks down pretty far and it's easy to catch on the ground, this stub will reduce that. SCAD file included.
