So, It has been a while,.. Running a blog takes more time than I was prepared to put into this. So basically I stopped updating. Good news, though,… the F5J as operational! I do not fly it enough but is is a nice glider. It is not very agile, maybe even e bit clunky, but it is a magastic plane, handles well, and land very accutate. I might see if I can give un update on the current hardware (also, read the first sentence….).
Inside F5J
Minor status update
I am having difficulties in keeping up with writing on this Blog. The “Inside F5J” is progressing well and I keep on making pictures, but writing blog-updates is lagging. Currently, the 3D-puzzle (i.e. the buildkit) is all glued up, the servo wiring is installed and the plugs are soldered. The covering is yet to commence.
Next update:.. soon!
Setup test for the Inside F5J: Turnigy 2217 860kv vs. PROPDRIVE v2 2830 1100KV
Setup
Recently, I came in to the possession of a motor test stand (RCBenchmark 1520) so I started to make some measurements and do a Setup test for the Inside F5J (Turnigy 2217 860kv), with a 10×6″ prop and a variation with the larger 11×6″ prop. First I put the props and spinner on the balancer. Remarkably, one of the props only needed a bit of sanding after which the total system was statically as dynamically pretty well balanced!
Then, I mounted the setup on the test bench and run some tests. I logged (approx.) 10%, 20%, 30%,…..90% Throttle.
The Motor/prop setups that I have tested are:
- Turnigy 2217 20turn 860kv 22A Outrunner & 10×6″ HK carbon folding prop
- Turnigy 2217 20turn 860kv 22A Outrunner & 11×6″ Aeronaut CAM prop
- PROPDRIVE v2 2830 1100KV & Aeronaut CAM prop
Let the building commence
So, with all the peripherals in order, the building can commence. Much is to be expected of the CNC Laser cut kit as I have not yet read a bad comment on the internet about these kits. Is instructed in the manual, I’ll start with the tail feathers. I will not get in to the actual logging of the build as the manual actually is quit good and provides sufficient photos.
So, as instructed, I took the plans and cut the tailplane part out, but not after we (@rob) made a digital scan and printed a copy. The original stays complete as reference material!
The plans are covered with plastic to protect them from sticking to plane once “glueing” has started. It is suggested to use thin plastic that is normally used to cover food, but as I have a lot of plastic that I used to cover furniture when doing some home-remodeling, That is what I use (I’ve got loads of this stuf, it is very thin and cheap). It’s about 3 meters wide so I need to untangle it a bit…
The first parts are cut out of the boards of Balsa. As everyone who build a CNC-kit from Höllein can confirm; the fit of the lasercut parts is phenomenal! As the first steps into building the Inside F5J are set and the first part is produced, I am looking forward to the process of “problem free” building!Tail Feathers
