Yeah, 1400kv and an 8x45 is not going to be great on runtime with a 3S. Run it on 4S and it'll make for a god damn rocket... for about 5~6 minutes.

These would be great for acro flying, I'm just not anywhere near that skill level yet.

You said you were going to to a v-tail as well?

Do you have any specs, or now where to kind any.

Ive been searching, but cant find a setup I like/ like Davids.

My full sized Tricopter w/APM2.5 was a failure, so the parts went into a full size X Quad. With the APM its super stable and might be fun for photography or GPS shenanigans, but I want something more... active.

My Micro Tri was a ridiculous failure, so I bought another ESC & motor to do a Micro V. Inspiration is something like this:

Micro VTail Grasshopper [MICROVTAIL] - $21.99 : BlueSkyRC.com, RC Things that Fly

KK2.0, 1811 2000kv, 5x3x3, 6a Plush (or 10A HK ESCs w/SimonK,) 3S and see what happens. I'm going to try desperately to keep it under 200g with 500/800mAh 3S battery. I figure I can solder everything together directly and save some weight on connectors. Maybe.

I'll be honest, I can't fabricate with wood for ****. If my DIY V does not work out, I might be tempted to purchase the above frame - OR - in the grand tradition of my previous failures, the parts will go into a super simple Micro X Quad.

I still have my RCExplorer tri body with David's yaw assembly in the garage. I'd like to build it out with some high quality 800-900kv motors and use it for LOS (and maybe FPV in the future) but I need to sell the 1400s first before I can justify buying more motors. I'll probably toss them on RCGroups this weekend if you guys aren't interested.

I'm thinking of making a wired quad. Probably would be a lot cheaper. 5 wires no?

Wired? As in powered from a tether?

The problem with that is the weight of the tether, you wont be able to get it up very far before the weight of the wire limits you. Plus, the longer the wire, the more voltage drop, so it will have to be even larger gauge.
The batteries and chargers are not expensive. If youre trying to save money, thats not the way to do it.
My original build is a good example of how cheap it can be. I think you could be flying for around 200 bucks with a multiwii lite board, a scratchbuilt frame, CF2822 motors and Lulin ESCs. Thats big savings in those components alone.

Yes 5 wires. In a wired design you dont need any remotes, you do not need any controllers, none of that plus you can use a giant 12 volt battery that will give you hours of flight time. All you need is the 4 motors and the props, the rest can be made by hand.

So no brushless motors? If you want to do it all arcane you might want to try some gyros like people used to do. Otherwise it'll probably end up plowing into the ground, you need something up there to sense tilt and speed up/slow down the motors. Its not going to stay level without it, unless you tethered the wires at the corners of a 20 ft square or something, lol.

Also, maybe what you want is a balloon? There's people out there that buy weather balloons and send go pros to space for giggles.

I spent all day building the new V-Tail. I took it out to fly it, and my dogs were in the back yard. I armed it, but motor 2 had come unplugged. I set the remote on the porch, and went to fix it (still haven't flown it), and my dog Gabby, being curious, wanted to see what would happen if she moved the throttle stick all the way up while my face was over the helicopter. 4 cuts, and, 20 stitches later. One cut went all the way through my right nostril.

I got home at about midnight from the ER, and had to see if it flew.

It does, as long as you don't put your face above it.

Well, chicks dig scars?

Good god man, I hate to say it, but I guess it could have been worse? All hopes for a speedy and uncomplicated recovery. I've had 1/2 my nose detached in the past, though it was with slightly more... precision and intent.

V-Tail looks good though

Yep, it could have got my eyes, that would have sucked.

The Vtail flies so much better.

I put a 4500mah battery, and the extra weight really helped with balance. It flies so much better with it.

Well that tears it, sounds like its V-Tail time.

What arm lengths did you end up with and how did you arrive at those lengths? FC is at CG I'm guessing? Also, could I beg a close up shot of where the V connects back into the frame?

Pro Tricopter Delrin Kit v1.2 — fpvmanuals


Half way down is a chart.

I chose 15" for the front, and 16" for the rear.

I will be dong FPV at some point, so I didn't want to go to short.
My Tri boom length was more like 18 which was not very good at quick maneuvers.
My second Tri had 17" front, and 18" rear, and I thought it flew better which is why I made the back 1" longer.

What I am trying to say is that I chose the shortest recommended for FPV which was 15"


The FC is not at CG, but it flies great. The battery can't go far enough forward to balance out the 2 motors in the back. Its actually pretty heavy in the rear. I will be playing around with CG before anything else.


I shaved the wood to meet under the frame.
The rear screws go through the wood, while the front screws keep the wood from coming apart at the front. I hope this makes sense.

I never disarmed it before, but you bet your ***, I will never go near it whiled its armed.

Also, I use to catch it in air to show people the way the FC works while in auto-stabilize mode. Hold it by one boom, and watch that motor stop. Never doing that again either.
