ah crap, I just realised, I might not have a spare channel for my nav lights :-( I'm getting a 6-ch radio, that's throttle, elevator, rudder, two channels for ailerons and flaps, that's 6. If I want my receiver controlled switch, I'll have to either put both ailerons on a single channel and sacrifice my computer differential and individual sub trim for each servo, or I can give up on my flaps. What do you think would be the best to go without, the receiver controlled switch, the flaps, or individual channels for each aileron? Any input appreciated, cheers. Hmm, difficult desicion you have there. If you must have all then you really would have to go with the single feed to you ailerons. It's possible to do mechanical differential if you are careful with where place your control arms (find a thread by Retiredbri, I'm pretty sure he did some calculations on this a while back). What you could try is to fit the ailerons with dual servo feed prior to cutting the flaps and try flaperons to see if you really think flap is worth it. If you think so you could always cut them in later, and use a Y (or reversing Y) harness to feed the ailerons which frees up a channel, or just stick to flaperons if you are happy (and still consider it worthwhile) with that setup. One other thing that may be an option is to research whether anyone has found out whether the radio board is actually built to support only 6 channels. I read recently that another budget 2.4 six channel Tx actually has a board capable of seven channels. Some Tx re-work and adding a switch enabled this extra channel. This would obviously void your warranty, and possibly your insurance, if you have any. |

Nice work Erwin. It would be good to see how well the flaperons work before I decide if I want flaperons or separate flaps myself.

Check next week then; I'll make another video and/or let you know how it goes.

Oh, could you show how to mix rudder with ailerons too? As I've mentioned, I'd like to free up a channel for my receiver controlled switch to run my navlights. I'm thinking about running both ailerons off one channel, and countering the adverse yaw with a bit of mechanical differential by angling the control horn on the servo, and mixing in a bit of rudder. I've been reading about it here: www.modelaircraft.org/MAG/FTGU/Part%2031/31main4.htmlAnother thing I'm thinking of, is running the navlights switch off the same channel as the flaps. The receiver controlled switch is activated whenever the signal goes over +50%. I can use from 0 to -100 for the flaps, and hopefully by momenteraly turning them to spoilerons I can toggle the lights on and off too. I'll have to have a fiddle and find out what works, when the last of my order finally comes back in stock! |

Just use your thumbs; you'll practice a highly useful skill for later models. |

After all it is just a SC, not a several thousand dollar jet or 100" W/S scale warbird which may need such. |

There I was, soaring through the clouds, and then along comes Ging to clip my wings and bring me back to ground level. That's a long way to fall man! Well I'll show all of you non-believers, you won't be saying it's 'just' anything once I get into emergency rescue and relief work with it. I'll be airdropping medical supplies to every refugee within a 2km radius, you'll see! My gf is getting me a GPS tracker for my birthday too so I can't loose this one either. |

Ahh Dillz, I didn't mean to shatter any illusions you had. Although the SC is pretty a good trainer, it's not the be-all. Think about it: Is it acrobatic? Is it fast? Is it capable of carrying heavy loads (full on FPV/camera ship/Aid work as you stated above)? Is it particularly good at flying in windy conditions? Is it a proper scale model? Is it a racer (pylon or otherwise)? Is it an indoor (gym) flyer? Give it a year or so of regular flying and you'll be looking for something else that does get a tick from one or more of the above questions. Sorry mate, but you know I'm making sense.  |

Can you imagine the confusing signal as it goes in and out?!  ;D |

I've just got the covering film from my LHS, I ended up going with profilm, which is apparently the same as ultracote. From what I've read, it seems to be the best covering film, and many people say they prefer it for covering foam to econokote, the 'classic' cub film that NECubFlyer uses in his videos.
I'm going to start with the fuselage and go from there, apparently it's best to go from bottom to top to hide all the nasty seems. I'm hoping the lighting I've installed isn't going to be too difficult to work around, I think I should be able to shove the LEDs into the foam enough to cover it, and then just pull them out again later and maybe secure with a little glue.
I don't particularly want to have to use multiple pieces of film to do the fuselage and wings, since the film is only 60cm wide. It is long enough though for me to get the length of the fuselage, and the length of the wing out of it, so if I use the whole roll up I can cover my whole wing and the whole fuselage without and extra seems.
Any of you have experience using Profilm on foam?

Well, I'm about to do my cub in it too. Any tips, did you find it worked well?
The main thing I'm wondering is if I should cut out long strips to do it (70cm long for fuselage and 1.3m for wings, or just cut the strips to the width of the section you're doing as shown in NECubFlyer's videos? Now that I think about it, with a 2m roll, I don't think I'd have enough to do it like that anyway, since you need a fair amount of extra film hanging off the ends of the wings to stretch it round with.
I've just cut a strip off of it to practice on, and a made a sock for my (mom's) iron. I'm covering a corner of a styrene box, and so far I'm finding it REALLY easy to work with, you can easily see when it sticks because it takes on the texture of the foam. Then after it's all tacked into place nicely, run over it quickly at a higher temperature to reheat the glue to a higher temp and shrink the film, and hey presto, you have an ultra thin layer of high tensile plastic wrapped around your foam :-)
