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!

I had that happen to me on my AXN Floater Jet, where the control horn clamps slipped, and it caused me to crash my plane hard. I've got a new floater jet on order so that I can have a good one in addition to my frankenglider

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.

After reading this thread and watching too many videos on youtube I've decided I really want a plane with autopilot, so I bought one of these: http://www.udrones.com/ProductDetails.asp?ProductCode=EXPCK1 . I got an airspeed sensor but no other options, am I likely to regret not spending the extra money on a magnetometre, telemetry, and sonar?

I want to fly helicopters FPV. What's a good setup to start with? I want to fly with collective pitch. I suppose fixed pitch will work also, anything but coaxial.

Unless you like the challenge of collective pitch, multi-rotors are really the way to go. If I had money, I'd hunt down a open pilot board (~100) and build a nice MR that can lift a decent payload.

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... http://www.youtube.com/watch?v=I1D3fvltj4Q&feature=related http://www.youtube.com/results?sear...559l0.1.3.2l6l0 Oh wait, they did... and have since the early 80s.

A CP heli would be awesome as hell, I've wanted to build a 450 for awhile now. The reason most people aren't into them as much for FPV is just because MRs are pretty new and with all the electronics they make a pretty badass platform for really stable shots. Aerial photographers use 6 or 8 rotor copters for their big HD rigs with impressive results. Check out Got Aerial, no wonder the lobbies against commercial UAV use has heated up, these guys with a $2k rig can make videos that used to cost tens of thousands. Imagine how cheap a UAV traffic reporting would be. On top of that they're safer than CPs because they just use plastic props 6 - 10 inches instead of a massive carbon prop that will slice a person into many pieces. They're not the safest things though. An FPV pilot should always be aware of what you're flying over and the damage you could do. CPs are awesome because: -Way faster -Fly more like a plane, high speed fast turns, dive, roll, etc. MRs have a lot of problems with descending and flying into their own propwash. -You have hope if you lose power, you can attempt to auto-rotate with some control. When an MR loses a motor it's catastrophic. -Run-time, I think you can get about 15 mins out of a 450 sized heli while a similar quad will do about 7. -Better in wind because the CP can almost react instantaneously whereas the MR needs to spool up or down the rotors to react, the bigger it is the slower it reacts. Check out this thread for the most badass CP FPV heli I've seen: http://fpvlab.com/forums/showthread.php?669-T-rex-450-fpv-pimped

Once you're comfortable with hovering in place (an amazingly difficult task!) and you want to start adding a camera rig you'll want to build a 500-class heli or bigger so that you'll have the added stability and weight-carrying capacity. Bigger = more stable = more expensive. ease posted:http://www.youtube.com/watch?v=L75ESD9PBOw Nerobro posted:I'm not buying it. http://www.youtube.com/watch?v=wrvAMyobsAw CrazyLittle fucked around with this message at 00:06 on Dec 6, 2011 |

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.

Nerobro posted:I'm not buying it. Electrical complexity > Mechanical complexity If you add stabilisation to a CP helicopter you now have all the added electrical complexity without gettting rid of any of the mechanical complexity. Also multi rotors do not have any sort of coupling between axis which single rotors have in droves. As has been said before as you add more motors you actually increase reliability because you are getting away from single points of failure. I have seen multiple CP helis crash due to failed control linkages. Vibration really isnt an issue with modern mounting systems. No power wasted in gear reduction drives or tail rotor drives. Seems pretty clear cut to me. You can get a KK board clone from Hobbyking for $20 and build a multicopter with that board for less than $200.

I'm not sure if this is the right place to ask, but I am looking to get my brother some sort of airplane kit for christmas. I was just going to get the harbor freight one, but I am betting there are better bang for my buck out there, I remember someone asking this a while back and can't find it anywhere. I would spend around $100 and who knows if he would even be interested in flying, but I would rather get something that doesn't suck for him to play with.

Are you any good at soldering? (simple wire-to-plug stuff) Getting into RC for the long-haul works best if you start off buying things that you can re-use across multiple craft, like getting a good radio controller. Otherwise, here's a kit that's got 99% of what you would need: http://www.hobbyking.com/hobbyking/store/__16542__Hobbyking_Bixler_EPO_1400mm_RTF_Mode_2_Throttle_Left_Radio_.html You'll need a 12v DC adapter for the charger that's included in that box. A lot of RC chargers are designed so that you can run them off your car battery in between flights. Here is some foam-safe glue so you don't melt the plane: http://www.hobbyking.com/hobbyking/store/__16427__Maxi_Cure_Extra_Thick_Pocket_CA_3_4_oz_USA_Warehouse_.html If you're looking for a more exhaustive list with stuff that's more beater-friendly, I can draw up something else for you. The suggestion above is simply the "easiest list to buy, shortest path to getting into the air" list. I'd suggest staying away from the harbor freight kit because those kits usually don't have parts that you can use on other planes. It's a disposable one-use thing instead of a collection of parts that you can use across all your planes.

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.

Here's the thing about size: bigger is more stable, which makes it easier to learn on. A micro plane is a poor choice for flying outdoors because the wind will make it very unstable. Yes, hobbyking is primarily based out of china, but the items I picked are In their USA drop shipping warehouse. It's also an epo foam plane so instead of waiting for repair parts, you glue or tape any broken foam, and if you have any electronics failure you just source those parts locally for cheap from the local hobby shop or online like nitroplanes.com . Parkzone makes great stuff but they're no different when it comes to farming all their manufacturing to china. Also the spektrum radio that the champ comes with isn't anything amazing to write home about. I'd say differently of it were the dx6i or dx7. Even then dsm2 isn't special anymore. Frsky is at least on par with dsmx and cost less than half the price. Coaxial micro heli are loving great indoors though. Damned fun on a rainy day.

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.

Nerobro posted: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. Yeah, the Bixler I linked to is 55" wide, and it's a decent plane to learn on with okay glide characteristics. If they're more willing to learn to glue all the parts together I would have suggested an AXN Floater Jet, as it's probably got some of the best flying characteristics I've seen for a glider/trainer, and they handle crashes and repairs really well too. It's just a bit more of a pain because you have to bring your own ESC, battery, servos, Tx/Rx, and that can be a bit daunting for somebody expecting to open the box and throw something in the air. Seconding the coaxial heli as starter-bait crack. They're brain-dead simple to fly.

I am liking that bixler, it looks better than the harbor freight ones. I am fine with soldering though, so if there is something better that just needs soldering I could do that too. I had a few crappy helis and didn't like them. They were air hog ones with only up-down and rotate though, so you couldn't do much with them. I had much more fun with my air hog plane.

blindjoe posted:I am liking that bixler, it looks better than the harbor freight ones. I am fine with soldering though, so if there is something better that just needs soldering I could do that too. Here's my plane of choice: AXN Floater-Jet The only parts you need to buy separately are:
The nice part about this approach is that the charger, battery, transmitter and receiver are portable between your different planes. It is more expensive up front than getting the RTF Bixler kit though. Here's what my list would look like: AXN Floater-Jet airframe + motor: $50 + s/h (~$60 total from hobbyking) From hobbypartz.com in California:
Total overall: ~$170 With that in mind, I would get the Bixler read-to-fly kit first to see if it really is your kind of hobby, and then if you're serious about getting stuff that you can use across multiple planes, get the Floater-Jet like I listed above but with a better multi-model-memory radio. Even then the Floater-Jet is "cheap" by comparison. Once you get comfortable with flying and putting the planes together (and repairing crashes) then you can get into building your own planes out of foamcore board or getting into building wood airfoils like Nerobro did above. That's when it becomes important to have a good charger and a good radio that can store settings for multiple radios. Here's my thoughts on the Bixler: It's got a lot of really great features for a first powered glider: Big wingspan, roomy inside, easy to work on. But the low entry cost does mean that they saved cost by putting in cheaper components than you would put in yourself (like on the floater-jet). The ESC and servos that it comes with are adequate but certainly not something I'd choose to put in another model. The wings are joined & stiffened with a 4mm carbon fiber spar that runs down the center of each wing, and the spar that ships with the plane itself is -really cheap- quality. Make sure to dial-down the response rate of the radio so that you don't try to do any hardcore loops or tight turns or you can "fold the wings" where the carbon spar splinters and the wings lose rigidity. BUT if you can keep your impulses under control and make sure to fly it gently, it'll fly beautifully. Check out Flitetest's youtube channel - they have a lot of fun episodes with plenty of good information. The "Bixler" is actually named after the straight-man of flitetest. Here's their flight review of it. (build review video) CrazyLittle fucked around with this message at 22:31 on Dec 7, 2011 |
