Nice bit of gliding there Chris.
Hopefully this coming Friday may be OK for our next flying day. Light winds, no rain & around 15 c
Thanks for your kind offer Mr Kermit.
Looking for probably a metal one that will fit a 9 x 7 prop & a 3.2mm motor shaft.
I can print one if you don’t have anything suitable.
Yes Gadget, it was great to finally get some flying time again, hopefully later this week we can do it all again.
Given that I needed to add a small amount of nose weight to the Zero to correct the CG I opted to reprint the nose-cone in a heavier configuration. I upped the line count from 1 to 4 which gives a far tougher nose-cone & adds an extra 40gm to the weight. The original lightweight nose cones (around 17gm) suffers a lot of damage if landings are less than perfect. Hopefully the stronger one will be better.
Once I print & fit the prop spinner the CG should be close to spot on.
Also programmed a radio knob to quickly adjust the elevator trim in flight so she should be good to go next fly day.
Got a fair bit more done on the P51D Mustang today.
All 3D printing now finished & tail assembled with servos installed.
I needed to pack one servo up a further 5mm so the control horns missed one another. The pushrods were originally designed with Z bends at both ends but they were too hard to install & impossible to get out after assembly. At least now I can remove the servos if necessary.
I will build the wings tomorrow & install & test the aileron servos. Once that is complete I can join the two halves of the fuselage together & install the rest of the electronics.
I have used 1.5mm CF rod in place of the heavy steel wire (as specified in the plans) for all the joining pins etc, resulting in a significant weight saving, especially in the tail area.
I may use a couple of 5mm CF rods for the wings as the plans only use 5mm 3D printed pins which are OK for positioning parts but add very little strength.
Maybe tomorrow I start to assemble a few bits & pieces.
The fuselage is finished. along with the tail, rudder & elevators so pretty much just the wings to print but I’ll assemble what I’ve finished first. Should have a spare motor around here somewhere to fit this one as it’s only a 680mm wingspan.
Looking more like a P51D Mustang every day
I don’t think we will get any reprieve from the winds this week unfortunately. Hopefully once Show day has passed it will get better.
Finally, my 3D printed Zero is completed, apart from the motor (which should be here in the next couple of weeks).
I gave the entire plane a couple of coats of clear gloss Acrylic Enamel as this tends to toughen the LW PLA somewhat.
All servos are in and set up along with the PWM ELRS receiver etc. Once the motor arrives & is installed I can tidy up the wiring & she is ready for her maiden.
I modified how the wing servos fit, don’t like glueing them direct into the wing as 9gm servos are easily damaged & almost impossible to remove if glued directly into the wing.
I will install some servo protectors as well before flying.
My homebrew black logos have been installed in place of the red roundels
Hopefully she flies as good as she looks !!
You need to read the post, not just look at the pretty pics GG, that is exactly what I stated in the 4th paragraph !!, but yes it’s coming along great.
Just cut the windows with the vinyl cutter while waiting for the wing parts to print.
Just to differentiate from Ron’s Zero a bit more I have gone for black roundels with a white Z rather than the normal Japanese Red roundels.
Hopefully it will look OK.
