There is an outline of a person in the fire of the first picture, and one of a bird in the other. Can you see them?

So, you just bought some o-rings, and it turns out that they are the tiniest bit too small. Here's a way that you can stretch them out so that they eventually may fit.

1. Locate two screwdrivers or something alike.

2. Put the o-ring between the two screwdrivers.

3. Use the lock area on a tool box to stretch the o-ring out around it, with the screwdrivers keeping it in place.

See pictures for more detail.

So, every year at my school there's this contest called Catholic Daughters. It's pretty much where you can submit poems, photos, essays, etc. to a place where they'll judge it and you can win prizes. This year, the grand prize in the state is $100 for 1st place. I've been able to make it to 3rd place in the state before, which is I think $20, and I've been really putting some effort into my entries this year. Wish me luck! I hope to win some money and use it to build something R/C!

So, I recently ordered a Hobby King Bonsai Flying Wing Kit, and I'm planning to use it for slope soaring in my backyard. There are currently 3 decent slopes in my backyard. I am standing on one in this picture, and you can see the others, too.



Slope #1 will most likely be the first slope that I will be testing out, depending on the wind. It has a deck on the top and a flat area in the middle, which, in the summer, will easily generate strong thermals. How do I know? The grass is dead, and that's the hottest area of my backyard, and the sun is always hitting it. I think that there's going to be thermals around there in the summer. I'd say Slope #1 has approximately 18 feet of slope, with an OK level of degree to it. It has the longest flyable-space width of the three. I think that this will be the BEST spot for slope soaring because:

1. There aren't any obstructions (like trees, buildings, etc.).

2. There are trees on the sides, but it is pretty clear 90+ feet in front of it to allow wind to travel to the slope itself.

3. The flying wing will be easily seen and controlled the whole time, because there isn't anything to block line-of-sight (LOS) view of the plane (like a Gazebo or trees).

Here's a picture of Slope #1:



Slope #2 will be the second slope tested (also depending on the wind). It is about 20 feet high, with a medium slope angle. It is after the thermal area in between Slope #1 and Slope #2, with a Gazebo at the top and a tree...Continue Reading

So, I finally made up my mind about my birthday and made an order from Hobby King. I found what I wanted, and then put it all in my cart and ordered it right away instead of waiting for a while because that backfired last time.

Here's what I've got on order. Sadly, my Bonsai EPP kit is one of those JIT items and isn't stocked in the large warehouse, which means 3-5 days more of shipping. Well, my birthday is on February 3, so hopefully my items will come then or that weekend. If not, I'll at least know that they're on their way.

2 x 6ch DSM2 Orange RXs (one for the SkyFun and one for the Bonsai)
2 x TGS Sport 6x4 Propellers (for my SkyFun Jet)
1 x 1 Meter 4mm Black Heat Shrink (1 meter for 50 cents!)
1 x Set of 10 Pairs (20pc) Nylon T-Connectors (Deans)
1 x X-Blade Precision Knife (only $0.49, I couldn't resist, and it will come in handy)
1 x Hobby King Bonsai EPP Wing Cores (for slope soaring)
1 x Zippy Flightmax 700 mAh LiFe 6.6v RX Pack (to power the Bonsai)
1 x LED RX Voltage Indicator for LiPo/Fe Batteries

TOTAL: $60.84 SHIPPED (I used my $3.40 in bonus points for a small discount)

I already have some servos that I can use with the Bonsai at home from the Tuff Trainer (I switched out the Tuff Trainer servos for some old Heli-Max ones that I had lying around).

I plan to do some slope soaring in the back of my house. If it doesn't work, I can always try to catch some thermals, or throw a motor and ESC into the Bonsai.

Or we would've at LEAST had a delay.

Time to pull out those snowboards... finally! Nice and powdery...

Well, I figured out what I was going to get for my birthday last night. I saw that Align T-Rex 100S clone, which looked awesome. It was late, so I figured I'd tell my mom and order it the next day (today). Well, it went out of stock overnight! Looks like I've got to figure something out, and I'm not going to get back into R/C helicopters, that helicopter was the perfect price for the other items that I was going to order from Hobby King that I really need, and all the other helicopters on HK are either out of stock or too expensive!

Originally I was going to get into scratch building for Christmas, but I didn't have enough money after I bought my Spektrum DX6i . So, I think that I'm going to go back to my original plan and get into scratch building. I have a few extra spare servos and now two motor + ESC combos, along with two battery packs, a 800 mAH one and 2200 mAH one (both 3S). That should be able to get me somewhere. As you've probably already noticed, I like to design planes and just about everything. "Dan Thinks" went from that to somewhere like "Dan Dreams", now may become "Dan Builds" LOL .

I figure that I can get some scratch building stuff from HK like a knife, blades, servos, cutting mat, etc., and just buy the foam at the local Home Depot.

I can never decide. Whatever... there's the plan for now.

I posted the first FPV in Space Prototype HERE, and I got some advice from brosius85, who gave a few tips on how the design could be improved. So, I had to put his ideas into consideration and design a second theoretical FPV in space design - the second. Here are his comments quoted from the first blog post:

radio control (ezuhf) can easily pass 100km. add some gain to the antennas and you could go a few hundred miles. video is the same. add gain to the video receiver and go as far as you want. a few hundred k's is not really a big ask.

propelors do not work without air. same way the wings cannot create lift without air.

rockets and solid fuel thrusters are the only solution without air.

e.g: even if a D40 capable of 200mph was pointed vertical and given full throttle, the batteries would be flat in about 2 mins and that's if you have not already burnt the motor and ESC
Here's what I got out of that:

-I'm funny. JK
-The rocket CAN have both control and video 75 miles + away
-Propellers do not work without air (DUH!)
-Solid fuel thrusters are the way to go for space FPV
-Wings cannot create lift without air (another DUH!)

Introduction:

I think a lot. I think in school, when I'm in a car, flying model R/Cs, charging batteries, in my study periods, when I'm doing homework, and every time that I can in between. It all started in August of 2011, when I started thinking about Science Fair, and what I would do for the topic. I wanted to build a generator, so I started to sketch designs for this generator, potential costs, how it would work, and when I could obtain these parts. Ever since, I've been drawing designs for just about everything, from generators to flying wings. I started keeping them in a binder, but I ran out of room, so I used something like it that could hold a lot of papers.

I have done a lot of drawings, ~90% of these are double-sided with writing on the back also.





When I first heard about FPV, I was really interested, so I started drawing FPV setups and everything in between, and got on a roll with those drawings. I'd like to start sharing some of my drawings on my blog here. Last night I was thinking, as usual, about what my first topic would be for "Dan Thinks." I liked FPV, and I remember Trappy from Team Blacksheep saying that he wanted to do two things in FPV in the future: fly to Mt. Everest and into space. FPV in space seemed like an interesting topic, so I started researching.

For a while I've been interested only in planes, but I really do like helicopters. I started with a helicopter that was too hard for a beginner to fly (Heli-Max AXE CPv3), and I guess that I thought that they really were impossible to fly, so I moved on to planes. Well, I really need something R/C to do around the house here, because the only time that I get to fly my planes is on the weekends, when my dad can drive me to the local soccer field. Of course, it's been windy on the weekends and fine on the week days these months, and it's just going to get worse. So, I think that I'm going to get a Blade 120 SR BNF helicopter for my birthday - I'll just have to convince my mom to get it! Actually, I'll probably just buy it used from here on RC Groups. Now that I have some positive feedback on here finally, I'll be able to buy/sell/trade with other members easier.

What really convinced me to start getting back into R/C helicopters was when I was at the New England Air Museum for the Open Cockpit Event. You can see that blog post of mine HERE. I was talking to a guy sitting next to two large helicopters, and he said that he'd actually flown both of them before, and never really got into fixed-wing flight. He was part of the Central Connecticut R/C Club. I went on their website and eventually got into the FAQ section for the club, and there was only one question. So, I clicked on it, and here's what I got:

I really like R/C Desk Pilot and BMI Flight Simulator (see my other blog post HERE), but it doesn't have a large selection of helicopters to choose from. There is no 3D helicopter to choose from, and I always liked 3D helicopters just to mess around for fun with sometimes (planes get a little boring after a while). So, I did a quick Google search and went to:

http://www.marksfiles.net/HeliSim/

I downloaded it - download took LITERALLY 3 seconds, there wasn't even a bar that showed the progress it downloaded so fast. I couldn't believe it. The graphics are great for a FREE simulator, and the helicopter movements and dynamics are amazing!

Try it out, I personally love it! And it's FREE and doesn't take long to download at all, which also means that it doesn't take up much space on your hard drive at all for your computer.

It didn't work. The Tuff Trainer didn't have enough power to lift the camera. But, the propeller was chipped quite a bit, so I will try again when I have some more propellers that aren't broken/chipped. Hopefully that will work!
