Airplanes that have graced our hangers and ramp...

Bigger flys better,9 minutes of mild flight with the 600 is nice.. could probally get 10 with better collective management. Now to get some better cyclic servos so i can have just a little more fun.

FPV---First Person View ,a very advanced equipment with high practicability for flying your models.
As I know,there are not more than 5 factories producing it in the world,
but known by many people and becomes more popular now.
The following are some details about it.

*includes:①Head Movement Tracking System ② small camera③ATX10 2.4G audio-visual transmitter④ARX 2.4G audio-visual receiver⑤7.4V800mAh lipoly for receiver⑥11.1V800mAh lipoly for transmitter⑦pan/tilt（including two 9g servoes）⑧2-3S lipoly charger

*Head Movement Tracking System(for example,X-GYRO1000):
X-GYRO 1000 is a kind of two axis head movement tracking system, based on high technology of sensor technique, designed for tracking complicated three-dimensional motion like head movement and so on, it can also be used on the areas of controlling drones and robots, transferring three-dimensional motion signals from hands, head of human to corresponding movement system on RC model, drone or robot.
The basic version of X-GYRO 1000 is specially designed for RC models with FPV(First Personal Version), it can be used perfectly with main stream transmitters that gets self defining trainer channel on market or to be co-operated with wireless high frequency modular independently. It can transfer the checked movement signals to transmitter, and the transmitter can send out signals of head movement or position of head( on two axis), so that the real synchronization can be realized when screen on the goggles displayed video pictures, users can look around as if he were inside the RC model. Since it is compatible with transmitters on nowadays market, it is easy and simple to use it and grasp it， its best advantage is that no need any fixed reference object to check and measure the inflection position of RC model, and no drift at all when it in stationary state compared with other facilities that need to make use of very complicated reference facilities or manual controlled transmitter, mechanical arms or other tools are heavy and not easy to be carried along, it greatly limited users’ freedom.
X-GYRO is compatible with high end FUTABA transmitters (FF-7, FF-8, FF-9, T9Z, T12MZ, T14MZ) supporting trainer/student function by using 6 pins square trainer connector. These transmitters can supply power for X-GYRO, no need external power. It can generate same standard PPM signal and merge selective pan/tilt signal channel into PPM, and then send it to model (default: channel 7 and channel 8 respectively, user can also define the channels for themselves), the system can send standard PPM signal to those unused channels, X-GYRO1000 can support those transmitters which can let users make choice on channels controlled by student (except of 1-4 channel) and controlled by trainer when mistake happens.

Since the FUTABA transmitters（especially the FF9/9C series），trainer switch is momentary switch, only if you leave it always “on” can realize its function. The simplest way for it is to hold the switch on with a rubber band. Other high-end transmitters such as (T9Z, T14MZ) have already put the trainer channel to always “on” channel.

If you have followed this hobby for a couple of decades or more, you know that the hobby was born thanks to a handful of pioneers that really left their mark with hard work while facing real challenges. There is a Hall of Fame Museum ( http://www.rchalloffame.org/ ) that can guide you through the history of all the joy that we now enjoy thanks to these pioneering companies and people. Problem is that you can't visit this Ohio based Museum. I am looking for support to move this great work of history to any of the Aviation Museums like those at Boeing Field in Seattle, OshKosh, Kitty Hawk, Dayton-Wright, etc.

Such a move would enable many more people to enjoy being able to see and enjoy the equipment that made this great hobby possible. If you are interested in supporting this effort, please contact me at jprado@gmail.com. This is a noteworthy effort that will ensure the proper and ongoing display of this hobby's birth.

Thanks,

does any1 have or no of good airboat plans plz comment me thanx venom racing team

Stopped at Northampton and asked Rich a few questions about the new 120 four stroke. He told me of a Macs flexible exhaust system to mount the stock muffler inside the cowl. He also make suggestions on how to build a test stand for the engine. Stopped at Lowes and picked up a piece of 1x6 pine, some screws, bolts and washers to bolt the engine down, and some large self tapping wood screws to mount the 1x6 to the test stand. Next I visited Dan's and picked up a prop, rubber bands for the fuel tank, an F glow plug, and a metal rod for throttle control. After visiting Mom and picking up the better half, at home, I cut the 1x6 to size and using a jigsaw cut a slot for the engine. I drilled four holes for the engine, and four larger holes to mount the 1x6 to the test stand/bay at Northampton and bolted the engine down securely to the 1x6. I mounted the fuel tank behind the engine using three thick rubber bands and made a z bend in the metal rod for the throttle control and slipped that through the throttle linkage and rubber bands of the fuel tank at the other end. I reamed the prop and mounted it and it's ready to test tomorrow. Hopefully I haven't forgotten anything.

Posted some questions on RCU about the flexible exhaust line routing and also about the servos I'll need, the receiver and receiver batteries. Got some good tips and links.

Until next time...

Did a little more work on the Zero. I've never built a balsa kit or scratch built anything, so I'm kinda working up to it by modifying foamies with scale parts. I'm calculating that I'll add about 1.5oz with all the scale goodies that are going on, but I'll use a small motor (FSK 3 bladed prop) and probably only a 1100-1300 lipo

Here, I've made the split flaps (from scale drawings) and one of the ailerons. I also cut out the foam above the flaps and thinned them the amount of the flaps, and figured out how to hinge and move them (kinda figuring the mechanics as I go along). In the last pic, I have one flap done and hinged, with the foam glued back in place over it. Seems to work ok, and I'll use a little rubber band on the linkage to keep the servo from being under load under normal flight conditions.

I'll spend 99% of my time on the wing, so the rest will wait a while. Within a week or two, I'll finish up the flaps and ailerons, and move onto the landing gear. I have the design work all done for the scale gear, so I "just" need to machine those... that will take a while. I'll probably use the zero gear as the testbed for integrated retracts too, so I have a little more design work to integrate the retract mech at the top of the strut.

Scratchbuilt airboat from blue core

SWAMP BUGGER AirBoat (3 min 43 sec)

Yes, I finally got another plane that had been sitting in a box for over a year off the shelf and built up. I picked up the Yak 55SP 10e blue and yellow version with the motor and ESC as a package from Hobby Horse about a year ago. Price sticker says it cost $230. (Wow, that seemed like a deal then, but now you can get (on sale) a 25e size Yak 55SP w/ motor and ESC from ALLeRC.com for $222.)

The Yak has a 38.6" WS and comes with a 30A ESC and the HP-Z3007-26 motor.

I used four HS-55 servos and I'll probably fly it with a 1500 mAH 3S pack.

With the APC 10x5e prop it pulls around 20A static.

17 5/8 oz, 670g total weight - which is right on the numbers according to the instructions.

Seems so small in comparison to the Brio and Sky Cat...

Hi all Can anybody tell me why I cannot get one of my spectrum servos to adjust where I need, right rudder is good but left will not allow me to adjust anymore,This is a dx6 that I am using and I went to end points and maxed it out still no luck for some reason right rudder will travel half inch or so left maybe a quarter I have this installed in a super cub cant figure out what is going on any ideas.

Well I'm a BIG ATV fan and a proud rider, hence the name Fox Rider 4. I've been Riding for about 5 or 6 years and started out at about 8 years old. My first and current ATV would be a Honda TRX 90 Sportrax and i really want to upgrade to a Honda TRX 250 Sport and ride on from there...........
This use to be my sisters old Honda 125 but it's out dated..

Dave has solo'd on his T-34. We flew one last buddy box flight Friday night, and then he flew several more on his own.

He is doing great and really loves the plane. He is experimenting with dialing the flaps down. I think he will probably add a servo to control the flaps so he can use them for take-offs and landings.

Now that he has three battery packs (got a couple of Rhino packs from Hobby King) he is getting in at least three flights each time he goes out.

The T-34 is really a pretty darn nice plane. It flies nice and looks great doing it. And the RTF starter package is one of the best deals around.

Some days nothing goes right,Enjoy.

3DHobbyShop Extra 300 SR ''Carnage'' 9-7-2008 (5 min 5 sec)

I flew the 32" WS Fokker DVII for the first time Friday evening. First flight was a bit scary, the trims were really far off and the plane is pretty responsive on the controls. It was also a bit windy. I managed to get it sorted out, flew around a bit, landed reasonably well.

Today I flew it again early in the morning before any wind had a chance to build. It is a pretty fun little flier. It moves right along on the little 400 size brushless motor. I'm using an APC 8x6 prop, cheapo ESC, and a 1300 mAh 3S lipo. Landing was an ugly one with a big bounce. No damage.

Since this is a 'fun scale' only, and the kit was very cheap, I don't feel as much concern when flying it as some of my nicer planes like the Sopwith Camel and Brio. So I flung it around the sky with abandon; doing loops, rolls, and stall turns.
