Wespe


Wing Span 74"
Length 71"
Weight 12 lbs estimate from 3d printing with ABS.

Based off of Esotech Hummingbird http://www.esotec.org/hbird/index.html. Will be using a longer tail like Pattern planes for better controllability. The prop is made from 5ea 20 x 14 prop halves mated to a custom hub. Motor is a Tomcat 160 expected rpm will be 5k on a 6 cell battery. Thrust ratio looks to be 1.3:1
Hover roll control will be fins aft of fan and with tail controls. Expecting 3D aerobatics.

Named this plane after the Heinkel Wespe and the Hummingbird.

Printed plane estimated AUW was around 17 lbs and static thrust looks to be around 20 lbs. I wanted a higher thrust to weight ratio so I decided to make the plane a wood buildup design. This will droop the AUW to around 12 lbs. I will use the printed shroud. Its weight is 2.2 lbs vs 1.2 lbs for a build up one.

Designed the build up version with devfus 4 and Devwing 3.
