micro Servo substitute=musclewire

I must have missed out on all that but I`m not up on all the news. I just got my first indoor plane,a micro fokker DR-1 but only got it out of the box to looky lol
I only fly micro/nano heli`s indoors,still prefer glow to electric and can`t get onto the idea of 2.4G or bind n fly yet,my lightest servos are 3g I think. But I did buy my first and second electric planes in the last year so thats progress right? but no,I can`t get a 2.4 to bind up ,I have to take it to the LHS and ask them to do it. Honestly, both my cp helis need to be done again for some reason they provide reverse trust like flying inverted so I have to hold the stunt button the whole flight while not inverted etc.
On the bright side,I did put the LHS on the track of researching muscle wire for use as servos replacements that they never heard of until last month.

I can`t build a plane light enough even with those 3g servos to fly with a TD010 on it but they do crash most excellent. No, transparent monokote type films are the lightest covering I have ever tried,not even silk/dope,just monokote type iron on like was popular in the 1980`s. Yes I tried the littlest stick and the clancy aviation "little plane that could" that Andy Clancy designed for the 010,but my friend built 2 010 planes for me that flew just fine.
thats where I thoght the muscle wire might help me out a bit. I figured it may function just as a servo does under the same "servo output loads" so maybe I could manage a 010 powered flying wing such as convert the radical r/c wicked wing from electric to 010 or 020 at the utmost.

But servos under 1g you say and in the mirror I now point the finger and say at the face I see

Im an indoor/micro type of modeler, 90% of my builds are under 10 grams, with the lightest being under 1 gram.. subgram plane.

Im currently working on a 24 inch ws plane for the 010, its the biggest plane ive built in 10 years.

The parkzone micro linear 1.5 gram servos, could easily be brought down to under 1 gram with a few simple mods, then you got the hobbyking 1.6 grams "standard type" servos that could also be brought down to under one gram, the toki biometal servos are 0.8 grams, the mechanical servos could be modified to 0.5 grams.

I wouldnt use a servo under 2 grams for a 010 plane, they have very little torque, especially the muscle wire versions, with the speed of most 010 planes its asking for trouble imo. They are best suited for ultralight slow flying planes.

Colored tissue from the wrapping paper store with 1 coat of clear dope is as light as it gets. Lots of fun. Put the tissue on with thinned white glue on the wood and water on the tissue, then after dried and taunted with the water put 1 coat of clear dope on for fuel-proofing.

If the airframe is heavy though, even the lightest covering won't make up for it. Hollow and perforated ribs, stick fuse, solid wood only where necessary, light balsa everywhere and "RC hard" only where absolutely needed.

Now, How on earth do you get an RC plane under 1 gram?

With alot of patience
Its a simple 2 ch rudder/throttle. Build light, make your own gear, (motor/receiver) actuator for the rudder, mine is 956mg ready to fly, a rather crude effort compared to the other modelers, it took me forever to finish it, the current unofficial record is 224 mg (quarter gram) which i dont think will be beat for a long time if it does.. it will probably be by the same guy... Search rcgroups, in the indoor/micro forum, there are a handful of us.

Sorry for the off topic post

Its all on topic, lightweight is lightweight which is where I was aiming with the topic anyway lol I read about some of those in Flying Models magazine from time to time but I`ll never go that far into electrics but modeling is modeling and most if not all modellers are friends in my eyes,the more the merrier,the more diverse the more overall growth and expansion can be achieved!!

Right on dude, agree 100%

Wow.

Hay I`m no polotician,I say if you can`t tell it like it is then just butt out and shush!! but especially in the case of those of us with common ground, we SHOULD just find a way to get along and respect eachother for our diferences and appreciate the differences because thats what keeps us all having the qualities than make us each unique in our own special ways and should be appreciated just as much as our common grounds that hold us togther

Its a forum for moddelers so its all on topic in 1 way or another to one degree or another. Thought process is always caused by stimulus of some sort so to break it down the "topic" is the inspiration for whatever you think up so whatever you say its all actually on topic in your mind;who am I to argue or limit that.

On other peoples posts I try to respect and bear in mind the "focus" of the topic, but on my posts/topics, anything goes as far as I`m concerned so have at it I`ll never complain and thats on record now

Yeah, I get that a lot, moreso from women, and no offense but its recieved much more graciously and less awkwardly under those circumstances but hay,I`m not judging



OOOOOOOOOOOOOOOOOOOOOOh, maybe you meant that little wonder of a plane............ummmm yeah I agree in that case

My hats off to you man,I won`t even waste my time and money trying that because that would be most definately the only result to mention

Nitinol wire has been around for a while. Not much power out of it but it is cool stuff.

Thanks for the kind words gentlemen, i really appreciate it!

I like the micro stuff, the smaller the better, majority of modeling i do is on the mirco level, i was never into the large stuff, thats one of the reasons ive always loved the 010, dont see my self getting into anything bigger.

Ive thought of getting a nano bee, but i hear they wear out fast, so i will stick to the 010 for the time being.


Im using the BA 3.7 gram servos on my 010 build, the 3.7-2 gram servos are perfect for the 1/8A stuff, as mentioned before i wouldnt go with anything smaller.

Cheers.

Mx, can you post a link to where I can read about building those micro planes, a forum maybe?
I searched and found some Japanese videos like the ones below. I learned from the comments that old cellphones are a good source of micro motors... for the vibrator, I guess.
Thanks,
Rusty

Yes we were using the magnets from 4mm cell phone vibrator motors, to build single phase brushless motors (as in the first vid). Development of the sub gram class started in 2004. Back then things were more difficult as the hall sensor we use today wasnt around, and people had to strip the vibrator motors down to the bare bones to get them lightweight enough.

Here is some reading material... (warning) theres alot of info to process

Looks like sub 10g can be done with off-the-shelf parts.

Hmm...

Phil

It sure can, gear is much cheaper these days also, the new deltang receivers will work with a dsm2 radio, no need for an external module.

Five years ago we were buying those airhogs livingroom fliers for the guts, IR tx/rx so range was short, but for 10 bucks.. you couldnt go wrong, i built a 4 gram 2ch 1/48th scale sopwith pup, that i flew in the living room. That plane lasted for 2 years before it finally fell apart from crashing into the wall/furniture/ me

Fascinating stuff. When I get to old to build in my shop and fly outside, I can roll around the geezer home chasing my gossamer creations, boinking the bald heads of all the other poor drooling slobs.

I enjoy flying indoors more than outdoors, no wind, no gawkers, and over opinionated lawn chair "scientists" gear is cheap, builds are simple... not dependent on the weather... i love my indoor planes, had a few beers? fly in the living room! fun stuff. i still have a walkera 4#3B micro heli that i fly regularly after having a few... never would with my modified gaui 200 or my trex 500 heli. I learned that early on attempting 3d
