nice radio, just looked it up on the Internet, I am using a not so reliable 35mhz Futaba 9cap. I am considering getting the 2.4ghz module, or maybe getting the dragon link. But will be using the ar6200 and dx6i for maiden.
Is the fact your fuse is made of carbon finer going to contribute to poor radio performance . I was told at one point that using carbon fibre on planes can reduce signal strength. Hoping my cf booms will be okay
3dr lockups seem to be when plugging stuff about but I dont think I did anything dodgy. Dont know why todays telemetry was so poor, nothing changed from day before. Cant see the mission planner when Im in the field so didnt know it was bad until I had finished. My set is an Aurora9 2.4. Can get all 6 modes with switches and it displays the mode on the TX screen - brill.
Fair play Rich, you work fast!! Must have been a bit worrying seeing it roll inverted! I'm going t do a similar thing with the avionics shelf, but will get a few flights done prior to installing the apm. What radio are you using? Doesn't look like a 2.4 or 35mhz..?
I also have a set of 433 3dr's. A bit concerned about them crashing mid flight.. Did you find the cause of the 3dr locking up?
Rich
After a few successful flights with the standard RC gear installed it was time to fit the APM. What on earth was I thinking when I thought that little avionics shelf was a good idea?
I did manage to cram it all in but was not happy with the arrangement so ripped it all out before flying.
A new extended shelf was moulded that clips on the old one and extends it. Also I have fitted an elyq regulator so that I can use a 2s lipo that gives 6v to the servos and 5v to the rest. It also incorporates a pocket for the 2s lipo so it is ‘self contained’ and easily removed.
First testing flight yesterday was ok in most modes but some of the automatic manoeuvring was more aggressive than I would have liked. I should have read the tuning advice more carefully as I discovered its FBW-B that limits bank angle not stabilize (after rolling inverted). Got good 3dr telemetry with the signal not going below 70%. Not so good today though as it kept dropping out with poor strength and I dont know why. The 3dr radios have locked up a couple of times now and have had to be recovered with a bootloader reset.
It is still a little difficult getting airborne off the long grass but I now have permission to cut a strip.
Ricardo, did you try to cut around the leading edge? It should be cut in 2 half’s, top and bottom (or visa versa). The wire will drag in the middle which is not a big problem on the flatter bits but will cause distortion around tight curves. Cutting in 2 half’s will leave a step on the L.E which can be cut or sanded off. There is a lot of advice on the net and youtube about cutting and glassing wings. You can get good results using weights to steadily pull the wire. Check out this VID.
I think my gravity wire goes about 15cm a minute but I havent measured it.
Leo, do you have any hint, or maybe a source material, for cutting the styrofoam on the hot wire? i never worked with this material (just found it in Brazil about 2 weeks ago), this week i made the molds (clark-y 200mm) and tried cutting it with AWG27 NiCr wire, on 24v AC and 600mm span. the molds were made on aluminium.
my problem is that the leading edge gets deformed, i'm not sure if i'm going too fast, if the wire is not with strained enough or if it's too cold. i'll try those modifications in the process, and hope to get something better soon.
Leo, good progress, the cf tubes are the business, super strong, and lighter than the alloy. The plane almost balances at 33% now. Fingers crossed i'll do a flight this weekend!
that's great, Leo! i never thought that the broken nose wheel could rip off the entire servo body, but problem solved, the takeoff on high grass was fine. but if you plan to fly always there, with this new huge motor and that big field, you can do belly takeoffs, if the propeller has enough clearance.
Richard, those tubes look the business. Much better to have some carbon wound around to keep the whole lot together. If mine show signs of splitting I will replace with those.

Richard. Good luck for the weekend, hope the weather holds up.
