Finally completed legs, protection and antennae placement for the 310 carbonecks frame.

Designed for 8 inch props, this machine weighs in at 410g without battery.

built to the lightest sepecification, all soldered connections, and a new extremely lightweight carbon composite frame. This machine is amaziingly fast with a 3S battery. Stick a 4S battery on for some unbelievable fun.

Rejoined my local club and even tho I have been sick most of the week, I braved it and flew all weekend.
Got sunburnt in the process but it was an awesome weekend! Unfortunately my friend crashed his 700 on his first flight on Sunday but he had his 450 as backup.
This video was on my last battery (3rd) on Sunday.

Well, I went to the store today and picked up some neon green strings for my purple LTD guitar, now it REALLY matches my MX2! (PS, in the background, that's my Kramer "Strat")

(also posting a couple of my Kramer, just because )
Thanks, RG

I've had a chance now, several times, to make a few quick checks of the performance of my upgraded F45 heli. As you may have read in my previous post(s), I upgraded this bird to a brushless main motor and replaced all plastic parts in the main rotor assembly (swash plate, blade grip assembly, flybar, and rotor head) with aluminum parts. I was duly impressed by the change in performance - - there is so much power available to the main rotor that I must use caution in apply throttle or the heli just "leaps" into the air and will reach 10 - 12 feet AGL before I can even react. The heli is much more responsive and will operate now in a light breeze (5-10 MPH max), where there was not enough main rotor authority and control to allow it to operate in such conditions before). There are other modifications I can do such as replacing the OEM receiver with an aftermarket (and better) one, replacing the cheap gyro and servos, and using a different transmitter. These mods will give even more control to a now decent flier. Lastly, if I would change receivers, I could also install a brushless tail motor and ESC, but the stock brushed motor works well as it is right now and motors are inexpensive. Once must also consider that this was an $80.00 helicopter complete with transmitter when I started out. I have another $80 or so in parts and upgrades into it at this point, so I'd be hard-pressed at this stage of the game to put another $50 - $75 into it (not including the transmitter). Happy Flying!

Steve

Okay guys, after reading much stuff left and right on how to stiffen a wing with carbon rods, or slats, where, etc.. I realized that even if I had a general grasp of the principle, I didn't have more exact data. So I looked it up and calculated what I could.
So here it is, as is, with no guarantee whatsoever.

There is a big document explaining in details (I hope) and the two main tables that derived from the calculations.

There are many more factors involved (mostly geometry) and especially in composite material (skins, skin adhesion, etc..) but this is a fair starting point IMO.

Have fun and make planes! (and feel free to comment critic, add, etc..)

Further study, comparison of horizontal versus vertical stiffening members.
For example carbon fiber slats in foam wing

I decided I should probably start a build log before I get too far along and forget some critical details.

To make a long story short, I saw all of the 3D printed planes the internet. Almost all of them were done on a SLS machine out of nylon material. The ones that were printed with consumer based 3D printers were....lacking. I thought I could do them one better.

Feel free to comment and ask questions as I go. I enjoy constructive criticism. Just don't be a douche.


I apologize in advance for missing some initial steps. I'm printing ABS material on a VERY limited build area, which is why the pieces are so small.

This plane is a prototype where I'm testing design ideas, printing methods, assembly methods, etc. It is a test mule designed to work, not exactly look pretty. I'll clean it up near the end.

This is a re-post from my blog, The View Up Here.

The biggest problem with most hat cams or helmet cams is that there's no way to aim them accurately. In a post on The View Up Here I mentioned a project to attach a reflex sight to a helmet camera to give me some way to keep the camera aimed at the subject. To that end I ordered a reflex sight and a Picatinny / Weaver rail to mount it on along with a Gopro Frame mount. All the bits and pieces have arrived, so I started designing. Then I realized this is really a scrap box project: the design and build phases are really one and the same. So I started over with the bare bits I wanted to stick on the helmet: a Gopro, an A2200, and a reflex sight, and got busy.


Reflex Sight:

The reflex sight has nearly zero magnification and projects a red dot into your field of vision as if you had a laser pointed out at the landscape. The idea is that once the sight is dialed in, the center of the frame of the camera will lie where the red dot points.


The dot is projected out at infinity, which explains the reason why I couldn't get the dot and the body of the sight in focus at the same time. (Dang limited depth of field!) Even though this one was made for a firearm, reflex sights like this have been used as wide field finder scopes on amateur telescopes for decades. Adapting one to this application seemed reasonable.

Walkera QR X350 Pro Problems & Troubleshooting

The newest walkera phantom-like quadcopter, you know the walkera qr x350 pro http://www.oomodel.com/walkera-x350p...r-p-66617.html
performs really nice, we seen some friends flied them and found there are a few problems which actually are not problems that can’t be shoot, we will just list a few common ones:

The first one we noticed was that some friends forgot to connect the little signal wire which goes cross the skid, this way the quad will not bind to the radio whatever you do, the signal light will flash at the first moment, and then keep blind.

The second one was that you may use your radio for different models, and you were playing 3d lasttime, so the 3d stick was positioned at a totally wrong place for quadcopter, this will cause a crash actually an upside down, so don’t forget to place it at the right position.

The last but most important one is, many friends experienced a very annoying phenomenon,they have to power the quadcopter up everytime after they landed, they don’t understand what’s the problem is, we tested the same quadcopter and it did in a different way. Actually that’s because they landed too harshly, and the quadcopter take it as a crash and powered off automatically to protect the quadcopter. It’s very easy and might be hard for some others to handle.

We will update when we found more common problems…

➢ High Performance – energy dense and charges 20 times faster than lithium ion batteries. It is also more powerful than other advanced batteries, operating above four volts.

➢ Cost Competitive – slots directly into existing manufacturing processes, requiring no change to existing manufacturing lines. Even more, the battery allows for consolidation of the supply chain, with only one active material — carbon. Additionally, manufacturing of the Ryden battery is under no threat of supply disruption or price spikes from rare metals, rare earth or heavy metals.

➢ Reliable – first ever high performance battery that meets consumer lifecycle demand, rated for more than 3,000 charge/discharge cycles.

➢ Safe – safest high performance battery chemistry ever developed. The Ryden battery eliminates the unstable active material used in other high performance batteries, greatly reducing fire and explosion hazard. Even more, the battery experiences minimal thermal change during operation, eliminating the threat of a thermal runaway. Finally, the Ryden battery can be 100 percent charged and discharged with no damage to the battery.

➢ Sustainable – contains no rare metals, rare earth metals or heavy metals, and is 100 percent recyclable, vastly improving the cradle-to-cradle sustainability of an advanced battery. Even further, Power Japan Plus is testing the Ryden battery with its organic Carbon Complex material, working towards the goal of producing the battery with all organic carbon in the future. http://powerjapanplus.com/about/news.html

Here is a small, very simple model that has only the bare essentials.
Originally it was made for indoor flying.
It's even simpler than a Tomboy or a Schoolgirl.
The wing was made first using foam ribs (15% Clark Y) and Saran wrap covering, just to experiment with.
It didn't weigh much, so how well would it fly? I made a stick body, taped on 2 small servos and a small BL powered by a 2S 350 ma LiPo. I didn't get a chance to try it indoors, but it did get a night out.
Basic construction is using a sheet of foam, or foam from a meat tray, or egg carton.

Saran model for indoor flying

Foam ribs with 15% Clark Y airfoil
LE, TE and spars are 1/8th hard balsa.
Half riblets are capped with silk span tissue and Weldbond glue.
Wing span is 24", cord 7.5" giving 180 sq in or 1.25 sq ft
Weight is 4 oz giving about 3.2 oz/sq ft.
Dihedral to suit rudder response.
Amount shown is not really critical, but is 4" at the raised tip.

The wing is covered in food grade Saran wrap.

Video shows out door flight on a calm evening here at the Flying Farmers model field, Ancaster, Ontario, Canada.

Hi all well its the 3x1000 gyro that has gone for all the months i had strange crashes,
SO over the months i have had times when on start up the gyro would start then stop and start again , then i have the times when flying the heli would go out of control it was like some one else was flying it till it crashed
the tail would never hold it would drift a little but towards the end the tail would swing out of control and then heli would spin to a crash
Now on testing the tail servo will only work plugged into the receiver, i tested servo and it works ok so some thing in gyro has failed
I have the xyzs gyro coming and hope this works trouble free only time will tell
