Finally got around to watching your video from last Wednesday, and another fine production it was Mr Frog, well done.
It would be nice to get another fly in before Christmas but it’s a busy time and days are limited.
If someone proposes a fly day I’ll see if I can make it.
In the meantime after my less than ideal landing with the 3D printed P51, the repairs are almost completed.
I have replaced the bent motor shaft (second one in 3 weeks – just as well I bought spare motor shafts in bulk !!) and repaired a couple of minor cracks in the fuselage.
Just waiting for the replacement wing tip to print & she will be good to fly again.
Most appropriate My Sinker, most appropriate.
Perhaps he was trying it out on Miss Piggy “pigs will fly” and maybe that is the reason for all these Doctor & lawyer visits .
Another fine video from Toad Hall Productions, caught all the action I missed when flying.
Not a bad turn up for a tad ordinary windy day.
Gee Kermit, Doctors & Lawyers on Friday, you could well be incarcerated by Saturday, especially with the way you have been abusing Miss Piggy lately.
Yes it was short notice & a lot of our regular pilots were otherwise engaged but 3 of us turned up to fly today, Kermit, Predator & Hoppy.
Greg (a mate of Hoppy & an RC pilot from way back) also joined us to have a sticky at what we get up to.
For Hoppy it was his first flight @ Sandford since returning a couple of weeks ago from the Phillipines so he was keen to get back in the action and brought a boot full of planes with him today & flew most of them.
Kermit finally found a couple of decent batteries for his Carbon Z Cub and after some minor hiccups managed a successful flight for a change.
I finally managed to maiden my 3D printed Zero and she flew perfectly (maybe slightly nose heavy with the 10gm of lead I added for the maiden flight)
Unfortunately I broke the old prop on landing (a bit too brittle with age) so only got one nice long flight.
Also flew the Bix 2 Sport & the Altus Twin without incident.
After we stopped for the customary BBQ lunch the rain returned so that was the end to flying today.
Hoping for some more settled weather in the very near future.
I forgot my Handicam today so had to resort to using the iPhone but hopefully Kermit got a lot more video than I did.
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.
