I started flying sometime in the early 90's. I've not been able to keep ships around very well.

Well Yesterday I bought a MCX. .... and I found out the controller was compatable with the ultra series of parkzone planes.

Knock $30 off a $120 airplane and i'm there.

I took home my t-28. And proceeded to do something hilariously stupid. The winds today are 5-17mph variable. And my flight area is small, and surrounded by 50' trees. That means it's turbulent as hell. Enough that when I was learning to fly gliders I learned to punch through the turbulence zone so I could land.

......... Four battery packs later, I'd finally damaged the T-28 enough that I had to give it up for the night. As it turns out, I can fly 4 channel ships without any real trouble. I'm pretty pleased with myself. I'm sitting here with elmers glue on my fingers and waiting for my repairs to dry. I think I'm happy with this plane. And I expect to fly it much more.

Maybe I'll have enough balls to take my 4 channel heli out there.

Lessons of the day:

#1 Change your transmitter batteries frequently.

I was flying... and lost control. That sick in the pit of your stomach, sheer terror, that comes from noticing nothing you're doing actually is affecting the flight of your plane.

That crash ended in a battery coming loose. And ripping the connector off. Which proceeded to short out and smoke. ... $8 of 150mah lipo down the toilet.

#2 If you crash once due to lack of control, don't just fly closer, replace those batteries. ......

I gave up after that crash.

I am STILL loving this ultra-micro t-28.

The one that came with it. It's not amazing.

As I am finding out, flying with the landing gear on is like flying with airbrakes on. The plane will fly at 1/3 throttle, easily, without the landing gear, it needs 2/3 with the gear on.

I also stuck it in a tree today. ... retrieval was by basketball. Woo, more damage.

Something feels like cheating when it comes to using dual rates and expo.

I learned to fly before ARF's hit the market. :-) Lemmie tell ya, buildinga plane just to crash it is a harrowing experience. My first "real" plane was a Future Flight Thermal Thing. A near 2m HLG that I put heavy servos in and flew off a high start. I built it with the wrong dihedral, yet it still flew well. I think it actually flys better than the one I built properly...

I have also built from scratch.

Sweet man. I built a kit out of balsa long ago but never flew it, was too scared. I love foam though! Gonna put a camera on the old .40 trainer one of these days.

Balsa flys amazingly. I am willing to bet, I could make a balsa version of my T-28 that's the same weight, and won't flex during maneuvers. :-)

And given how beaten to crap my current airframe is, that might not be a bad idea.

well crap. I bought a new airplane.... Because hte old one was flying like a whale. I thought it was because I had to much weight on it. After buying the new plane, I investigated moving bits over from the old airplane to a new airframe.

I discovered that the elevator was torn, and the servo horns were all floppy. I fixed that last night, and it now flys well again!

Oh the joys of a laser cutter.

Wings are something I hate. So I work on them first.

I got bored of wing building....


And after three hours of build time, I had this.


Tonight I finished sheeting the wing, and the fuselage.


I think I want to put pretty wing tips on it. I need to decide what servos to use, and what's going to power it.

Multiroters are far better suited for FPV than conventional helicopters.

But as has already been asked can you currently fly helicopters or airplanes?

I don't understand why people think multirotors are any better. Instead of having the main shaft, and body of the heli providing some dampening you're directly attaching high frequency noisemakers to your camera platform. To make a conventional heli shake free you just need to balance two blades. You don't need to worry about interaction between rotors. You have a larger swept area for longer flight times.

Multirotors also have the distinct disadvantage of being utterly unstable. If you add the sort of stabilization you need to keep a quadcopter flying to a conventional heli you'll have a camera platform that rivals a steadycam. You'd wonder why the film industry never thought of that...

What are the advantages. What advantages would be there if you put the same sort of gyroscopic stabilization on a conventional heli?

Nerobro
Nov 4, 2005

Rider now with 100% more titanium!
If you're flying someplace, an antenna down is just as effective as an antenna up, and you'll be further from the noise of all the speed controls. Hell, mount your antenna on the end of the tail rotor for some serious electrical quiet.

Any electro-trickery you have on a multi rotor heli will translate happily to a single rotor craft. (I'm saying if you put one of those advanced gyro stabilized boards in a single rotor heli you'll have a more stable platform.)

I will not buy that the vertical dimension of either sort of aircraft is any limit to where you're flying it.

As much as hobbyking being stupid cheap rocks, they are also not based in the us, and you're not going to get repair parts fast. Your best money would be on a parkzone ultra micro champ or cub from the local hobby shop. The champ may get you out for less than $100 with tax. The cub will be a little steeper. Both are three channel rigs, which makes them a lot easier to fly. If he likes it, he can use the same transmitter on the mcx, msr, helicopters, and a bunch of 4 chanel airplanes later.

Truthfully, I would go the heli route. $80 buys you a mcx, radio, charger, and battery. And that radio will work with a dozen other models. The big benifit of the heli is indoor flight, he can fly any time,not just in calm conditions.

At this point price defines size. I would recomend something 30" or bigger for learning. Something small enough to bounce, big enough to not be a twitch fest.

I learned on 2m gliders. They were gentle in yaw, vicious in pitch. :-)

I think the best gift is a coaxial heli. It won't be dead on the first flight.

I live in Canada on the shoreline of lake Huron. The winds are incredibly strong in the winter once the ice builds up.

So we made arrangments to get a gym for 2 hours a week and flying foamys.

This is the reason to build fast, heavy ships. Faster planes care less about crosswinds. :-) Heavier planes care less about turbulance.

... can you tell I have big ship envy? My Spirit 2m is on the shelf. But I need to build a new tail for it, and buy a new high start. Did you know surgical tubing turns to hard candy after a decade?

So I was busy tonight. I bought $17 of balsa, $17 in paint and sandpaper... and started to build my Nano DLG.


Some Electronics... The reciever case is 7g, and will be shed. As will all the connectors that won't be needed. (a full half of them!) I will be using my e-flite batteries for this. 120mah will last until I'm done.


Yeah, I do my building on the kitchen counter. Marble is CyA proof!


The first fitting of all the parts. The tail is painted properly. I will be doing orange tips on the wings too.


With reciever, but the wings aren't sanded yet.


About 1/3 of the wings ended up as a fine balsa color powder.


Oooh, airfoils.

The plane got it's first coat of laquer so I don't have a final shot for the night. But it was 55g before some post paint sanding.

And I even flew it tonight.

Sadly it flies like a brick. Here's why:

It IS a brick. I'll bet I can really get some altitude with that much mass behind it.

I modified my reciever.


I figure I can save 10g with new servos. I can save a few more grams trimming cables, and removing the metal plugs on the receiver. And i'll bet I can save 5g shaving off some more paint.

Yes, I built it in two nights.

So I'm taking another shot at building my Nano DLG under 50g. The last one met a terrible death while trying to imitate a javelin. It's in four parts now...

So here's the build process...







Shaping the wings should bring their weight down from 22g down to 11g. Which gives me something like 25 grams for radio gear.

3.7 grams for the receiver.

Carbon is just so sexy.


I was expecting it to be a lot harder to apply. With some care it goes on quite flat and with a very even width. The plans for the plan recomended using a plastic shopping bag to smooth out the carbon tow. I wrapped packing tape around my finger, and that worked out well.


I made a little table so I could make the airfoil even. I didn't do that last time.


Now it just needs radio gear.


Watson always thinks he can help. Fur and CA aren't a good combination. If you look closely you can see the elevator is sprung up. Since there's no radio gear there's no tension to hold it down. If I am really lucky I'll get a package from china today.

The MSR is HARD to fly. Don't start with it. The MCX will happily fly in 450 square feet, and you will have fun flying it there. It is fun to fly in 100 square feet, much less 400.

Get the MCX. It's worth the $80. Once you are sure you like it, the $80 for the bind'n fly MSR makes more sense.

Bigger rotor blades will help. A lot. Like double the span. Goto to like a 12x2.. if they make them. You've got the space, you're just wasting swept area.

Has anyone built their own airframes as opposed to buying one off the shelf? Could a larger vehicle be built from blocks of balsa or foam that could carry heavier payloads? I'm thinking of something capable of carrying in IP dome camera that could be imbedded on the underside of the fuselage to allow for 360 degree pan and decent zoom.

On a separate note, is there any type of program that would allow an operator to freeze a camera on a certain point as in see a building, centering in on it, pushing a button, and having the camera stay pointed at the building while the aircraft might be flying in a different direction?

Yes, hobbiests have been doing just that since the ... 1930's? I've built a long series of planes with wingspans in the 6' range, out of balsa, plywood, and spruce. People do fiberglass, foam, carbon fiber, all the time.

They also make real airplanes the same way. :-) The KR-1 and KR-2 are built just like a radio control airplane.
http://kr2s.r-farley.com/Construction/fuselage4.html
Seriously...

If you want a "off the shelf" large airplane, they're out there. I'd recommend the Telemaster. That's a plane that's been the go to heavy lift r/c plane for at least the last 20 years.

http://www.hobby-lobby.com/telemasters_216_ctg.htm

The reason why you'd go kit, versus ARF, is it's easier to incorporate modifications into a kit, rather than an ARF, and if you're careful, nobody will build you a lighter plane than you building your own plane.

A rig that will track a point in space is a very, very tall order. I wish you luck on that.
