I began making a scratch-built Skywalker (SW) rc plane based on plans from rcgroups. “IF” it flies and wont weigh a ton from my usual over design tendencies ill be using it for long range. My target is it should have a base, empty weight (sans ALL electronics) of not more than 600g 800g*. Or a total flying weight of not more than 2.2Kg fully loaded with all the RC, Servos, 5000mah 4S LiPo, APM2.6 and FPV gear etc.
So far I’m done with the cutting of the main wings and tail assembly (rudder and elevator) which took a ridiculous amount of time: I couldn’t decide whether to put the elevator on top of the rudder (like the pre-CF tail 2013 SW) or below the tail (somewhat like the 2013 SW). Eventually decided to do the latter so i won’t have to strengthen the rudder too much. The downside is the elevator will now be more prone to landing (or crash!) damage.
Here’s the tail section:
A closer look at the the attachment points: the end of the tail spar on the right end is a ballpoint pen casing where a barbeque stick glued to the CF spar can be inserted. This is secured by PVC/plastic strips glued to the elevator and secured to the base of the rudder with a screw and nut.
..and attached to the base of the fuselage last night:
Target Empty Weight:
Weight at this stage: 175g
Balance left: 625 g
* found out that the 2012 186cm SW is 700g empty.
