Put some up elevator trim on when you launch as well. May as well overdo it as it porposing on launch will at least be an improvement to nosediving.

rotaryfun posted:Got my amazon box in for my ProtoX, only to find that instead of a ProtoX they sent me what looks like a cheap knock off. The CX Model CX033 (http://www.amazon.com/CX-Model-CX033-Nano-Heli/dp/B00KQX48NQ). I've already setup a return/replacement order with amazon but took it out of the box to test it out anyway. Found that the cover has a broken tab and the battery was popped off the control board and that one of the props was off the motor and seems to have a crack running down the length of the propeller body. So I just got my replacement ProtoX in and it seems that this is what they are sending out now when you buy the ProtoX. It's in a CX033 box (same that I originally got), but it has a ProtoX inventory sticker on it. So I don't know. I was able to fly this one and it was very stable. The controller isn't so hot but it is what it is. Was able to fly around the office, so that's cool. Nice new office toy.

My latest project is a 275mm Y6 multirotor, Hex-y. It's running Cobra 2204 1960kv motors, 12amp MRSS ESCs, Naze32, and 5.8ghz FPV with a PZ0420. It's not supposed to be indestructible or to set world speed records, but instead to be a stable and powerful, compact platform to carry an integrated brushless gimbal with a GoPro or Mobius. I got some local help with the initial design and also laser time  Final version will be .060" G10, but this prototype is .125" birch plywood.

Definitely post some video of that thing flying. Looks like a substantial beast. Only thing I wonder is how it will do in wind considering the tall sides.

Yeah, 450 g with tall sides like that might get a little unsteady when it gusts. My quad on the HAL 585mm frame is...900 g? 1200 with battery? It's pretty steady in the wind, even with the R2D2 dome on top, but it doesn't have the same broad, flat sides you've got there.

We shall see. I've actually noticed that the mini MRs perform way better in high winds than you might think. Some of my friends 250 quads don't even seem to notice the wind. It could be the small cross-section like you guys are saying, but I've seen some minis with nearly as much side area once you add a Mobius and battery on top. I'm hoping to have the FPV maiden later today, but the only 3S 2200 batteries I have are at least 2 years old and I might not get more than 3-4 minutes of flight on each one.

I hope the weather keeps up here, Got some amazing Water Ski footage last weekend and hope to get a ton more along with all the other stuff going on at our private lake this weekend. Live band, BBQ Potluck, tons of water sports, it should be fun and make for some excellent footage. In ATTI mode the P2 can easily keep up with barefooting too.

Just finished up the build of my HK Q450 quad. It was a decently easy build over a couple nights. Already really loving the KK board for its simplicity. Also already can tell that I'll need to replace the bottom of the barrel HK motors I ordered with something better, you can just feel that the bearings are not that great. Also the HK props are not perfectly balanceable because the hubs are drilled off-center slightly  Either way, for now its good. Had the first "can this thing get off the ground" maiden in my garage tonight. The answer is "yes, when the motors are hooked up in the right order", which they werent at first. Looking forward to maidening it for real this weekend.

Did a real maiden today. Maidened it with auto level on. That was a mistake. It was drifting like crazy and I had to fight to get it anywhere. I turned the auto level off and it flew much better. I'll see if I can calibrate it some more, because I do see auto level being useful. It yaws pretty slow and tends to overshoot the yaw. Any recommendations for adjusting that out?

Flies with a 4S 5000 and hovers at half throttle! It's crazy. Hopefully vids soon, but just moved and no internet. ESCs never really got what I thought was too hot. On a 4S 2800 it hovered at quarter-throttle and nothing go warm. On your post I decided to remove the BEC from 5 of the ESCs and use the top rear motor BEC, I'm thinking that motor has the least load on it and the ESC is more roomy.

Yesterday I purchased a Hubsan X4 expecting it to help train me on piloting while I wait a few weeks. Does it maneuver like a DJI Phantom? ...I probably should have asked this before I purchased it.

Man, before you know it only the government will be allowed to fly with a camera. While I understand where the laws/regs are coming from, I feel that some of this is a bit overkill and a Drone as small as a Phantom, and at the correct height not to be a hazard to the mortar traveling near 80%+ its correct detonation height, then it shouldn't be over a populated area anyway (usually the fireworks don't explode directly over a Crowd). But it will only take one asshat who will fly his drone right above the Launchpad and right over it as a mortar comes out, hits the drone, and causes the rest of the display to go up...  The Risk Averse world we live in is a downer though for all things aviation alone. ^And to answer above, yes the Hubsan X4 will give you a good idea of how a larger drone will fly, however it will be much more difficult as the Larger drones like a phantom are technically more stable due to size and the more advanced controllers, etc. If you get to piloting the Hubsan really well, you will fly a phantom quite good as well. The Hubsan flys similar to a Phantom in ATTI mode, but with manual throttle.

I find my Estes protoX to be easier to fly than my q450 with kk 2.1. Probably because it's significantly less likely to severely injure me/others.

Uh you werent kidding. I stopped by the LHS after work today and picked up a set of APC Multicopter props in 10x4.5 They were all really really close to being perfectly balanced out of the box, but I taped them anyway because the  in me could not let them go slightly unbalanced. I tried a hover with them on and its like a different quad already, much more stable and a ton quieter.The only thing I dont like is APC feels the need to file their props to a razors edge before they leave the factory. I never understood that, even when I flew APC props on my planes I felt like I had to be extra careful around them because they were so sharp.

Customfresh posted:Thanks. Not sure what to read, maybe hit up a few YouTube videos flying quads for beginners. Also hopefully you got a Crash Kit and Prop Guard with it as you are going to crash, and you are going to break a prop or two unless you fly in an open field. Just take it slow and get used to the orientation of the drone based on the lights. Try flying it first facing away from you so it is natural, then work on flying it facing left, right, and toward you to get used to the way the controls change and how your mind handles it. And flying it outside is way more fun then inside. the X4 can flat zip and it has been a fantastic Dog Walking tool as well. I got to get some of the video edited and posted on Youtube of that.

I was tryin to be a Good RC Person and learn to use manual on my phantom 2. They treat manual mode like you have a regular, non spring centered throttle, which is really loving surprising when you switch from atti to that! I also stuck some LEDs and some landing gear zip ties to my syma x1 last night, after my friend promptly lost my previous syma in someone's backyard during 4th of july. I'm kinda interested in making my own now. I'd like to do something faster and/or more acrobatic. I don't know if I'd want to go with a quad or a tricopter though (or really where to start in general). Any help would be appreciated.

Main problem with the hk mini frames is durability. They are made out of standard glassfiber rather than G10 or CF so they won't handle crashes as well. But for 1/4 the price  That 230 frame is pretty much a clone of the blackout but in glassfiber.

X frames are more nimble because the weight is closer to center of mass. H frames hold more poo poo and are better suited for FPV because it pushes the camera up forward beyond prop-view. Over/under doesn't matter that much. Having a lower CG can provide upright stability for FPV rigs in flight, but also potentially make landing harder (uneven bottom).

It really doesn't make that much difference unless your machine is very underpowered. I would go H frame just for future proofing if you do want to fpv later. Quads are cool but quads FPV are

There was someone at the Jets Over Kentucky with a pretty awesome 6-prop copter. Had retractable landing gear which I have never seen before on a quad (or whatever variety). That thing had a pretty good size battery, as it hovered and recorded jet passes for like 15 minutes (he was doing video for the event, so it was pre-approved and such).
