RC Planes

Yes I imagine it will take a while. :p I didn't realise you could make a wing so easily, I thought they had to be a very precise shape, a la big planes and the like.

Are they sturdy enough to carry decent batteries and props and all that? I saw that one guy on rcgroups uses a glue to harden the surfaces, is that what you do?

At lunch I thought I'd have a go at modifying my FlySky 9x with the Smartieparts board, thinking that I wouldn't be able to finish it, as I have the V1 board.

Turns out I have V2 board, so was able to do it all. I have the backlight installed and a USB connector now hanging out of the battery compartment. Unfortunately I have to find a mini USB lead now and do some work, so I can't flash it yet, but will be giving it a go tonight.

Looking forward to the backlight most of all at the moment, and the potential to turn off the sodding beep. And swap the +/- buttons round, as they're back to front. :p

On rcgroups there is a section for scratch building where you can get pdf plans to work from. My flying wing I pictured earlier was made this way, on the middle layer of foam I cut a v into it so I could stick a carbon spar across the length, that's all you really need to strengthen the thing. Strong fibre reinforced packing tape is a good way of add strength to foam too, as you can see on the leading edge of the wing (I also have plastic rods behind the tape). I have a 3d shockflyer half made from years ago, not sure whether I will ever get round to finishing it. :p

My wing is a KFm-4 aerofoil, it seems good at both speeds and slowing down for landings.

I'll have to read that when I'm not drunk. It'll make more sense. :p

I managed to flash the firmware of my FlySky 9x earlier, and it it looks like it supports PPM, PXM (? is PCM in there somewhere?) and DSM2! Which - I think - is what the Orange Spektrum receivers I ordered use? That would be a bonus if it works with those receivers! Also I can see that I can change the number of channels from 4 to 16. Awesome. Undercarriage, flaps, bombs, miniguns, lights, FPV, exploding dildos - here I come.

So it's infinitely better already. It knows my name, it has numerous more options, interacting with the menus (which are doubled by holding down the Exit button and a direction on the d-pad) is huge better... I just don't know what any of it does. :p

It somehow looks a lot more impressive when it's backlit. :p :cool: It is munching my 8 x AA batteries at an alarming rate though, even though I'm not doing anything, so next will be the cheap Lipo mod.

Sounds good! And yes DSM2 is Spektrum, didn't realise it could do that. Very tempting to get hold of one now and give my Dad my 6EXA. :o

It was £55 for the transmitter with an 8 channel receiver included, then about £30~ for the Smartieparts board and (included) backlight.

The PSU has arrived for me to start modding. 32amps at 12v of charging power. :cool: ;)

Bugger. Thought that was too easy. :p

This dude has got an excellent, if slow, because he's not English, tutorial on how to use the er9x firmware on Youtube. I am starting to get the idea around mixes and so forth. He explains airbrakes, splitting ailerons and all that jazz. Sounds awesome. :cool: :D


You got your stuff yet arknor?

Actually that flysky v2 is /exactly/ the same as the one I ordered from HK, the 2.4Ghz module is integrated as well. Can't wait to hack it up!
The HK comments on the receiver also say you can strip it down to 9g by removing the box, connectors etc..

on yours the aerial is connected to the module by a wire on the flysky the aerial should be part of the module

I use an old AT style psu for my power supply, modded it by putting banana lead connectors on the top, my charger isn't a very high rate one so it has enough power for it.

Out of interest, how much are server psu's to pick up?

Edit - Looking on the net sub £10?! Seems really cheap for a good power supply, 32A at 12v aswell, now that explains why you see some people hooking up 2 to get 24v.

Yeah, the one I have upstairs was £9.99 inc. P&P. Obviously they're just recycling servers, whipping out bits and flogging them on eBay for cheap. I have a link to a 100amp server PSU but it's £45~ or so. Thought that for what I need, and more importantly what I want to spend, I'd keep it right down.

It's piece of piddle to wire up as well, only looks like another 10 minute job just to get it going with 32a output.

re: 24v - that appears to be more complicated. If the two cases touch then they become live, or something like that, so you either have to poke around internally or ensure they will never touch somehow. Thinking about it I might pick up another whilst they're about as they're so cheap and have a go in the future, but for the time being I don't really want the risk of electrocuting myself!
