Long distance speedskating
After finishing several evening studies I can finally pick up a sport. The sport I like the most is speedskating. Last year, 2008/2009, whe had a great winter in the Netherlands. Ice as far as one can look! I like that. It makes me feel a real dutchmen. When the ice is in the polder my blood starts to boil. Last spring, summer and autumn I'm training for the alternative eleven city speedskating tour. My personel target: speedskate 200km within the time limit, without getting deadly injuries

22-01-2010 will be my day.
training consist of + 6000km a year on this bike:

One evening in the week "drytraining: e.g. Slidingboard, longdistance running (8-10km) or jumping to improve force and explosiviness.
One other evening will be spend on the ice. Mostly in Utrecht, Vechtsebanen.

TamJets A-4 SkyHawk EDF Jet Maiden Flight
On The Maiden Flight, What Adrenaline Rush, The A-4 Fly's Great, I'm Very Impress With The Tam's A-4 SkyHawk.
On The Maiden Flight My Controls Where Very Sensetive To Me. When I Turned, I Felt The Jet Wanted To Roll Almost Instantly. So It Had Me Very Nevous, Also On My Landing I Had My Car Parked To Close To Where I Was Trying To Land As I Was Nervous To Come In Low, So I Had A Terrible Landing And Bent My Front Nose Gear Steering Column, Glad Tam Sells These Little Parts As It's Only A $20 Part To Have Me Back In The Sky's.
Look For A Better Flight Here Soon.
What Adrenaline Rush.

Rc Plane In Tornado!
Ive thought about this for some time,today while checking out storm chasers on the discovery channel on youtube it looks like someones finally trying it. I enjoy the shows but thought the deploying of the probes was just to random. Im sure many will see the cons of using an rc plane to get footage as well as the risks but the chances of success will be much higher if they can enter the tornado rather than hope it goes in the right path and data and video are logged on a ground probe. Looking forward to seeing more on this one.
Heres some of the footage i found so far on this project.

servo introduction
servo introduction
Servo - Introduction
A servo is a motor that is attached to a position feedback device. Generally there is a circuit that allows the motor to be commanded to go to a specified "position". A very common use of servos is in Radio Controlled models.
R/C Servos come in standard "sizes" (so that they fit models well) and use similar control schemes. Unlike general purpose motors, R/C servos are constrained from full rotation. Instead they have a limited rotation of about 180 degrees or less. This is sometimes changed (see "Servo Modifications" below).
R/C Servos are controlled by sending them a "pulse" of variable width. The parameters for this pulse are that it has a minimum width, a maximum width, and a repetition rate. These values are not "standard" but there are conventions that are generally accepted. The convention is that a pulse of approximately 1500 uS (1.5 mS) is the "neutral" point for the servo. Given the rotation constraints of the servo, neutral is defined to be the position where the servo has exactly the same amount of potential rotation in the counter clockwise direction as it does in the clockwise direction. It is important to note that different R/C servos will have different constraints on their rotation but they _all_ have a neutral position, and that position is always around 1500 uS.
These servos are "active" devices, meaning that when commanded to move they will actively hold their position. Thus, if a servo is commanded to the neutral position and an external force is present to push against the servo (presumably through the mechanical linkage) the servo will actively resist being moved out of that position. The maximum amount of force the servo can exert is the torque rating of the servo.
When the pulse sent to a servo is less than 1500 uS. the servo positions and holds its output shaft some number of degrees counterclockwise from the neutral point. When the pulse is wider than 1500 uS the opposite occurs. The minimal width and the maximum width of pulse that will command the servo to turn to a valid position are functions of each servo. Different brands, and even different servos of the same brand, will have different maximum and minimums. Generally the minimum pulse will be about 1000 uS wide and the maximum pulse will be 2000uS wide. However, these are just guidelines and should be checked on the servos you use. In particular if you attempt to command a servo past its maximum or minimum rotation it will use the maximum amount of current trying unsuccessfully to achieve that position.
Another parameter that varies from servo to servo is the slew rate. This is the time it takes for the servo to change from one position to another. The worst case slewing time is when the servo is holding at the minimum rotation and it is commanded to go to maximum rotation. This can take several seconds on very high torque servos. Typically it takes less than two seconds.

Speed and Torque Ratings
Speed and Torque Ratings
Other than physical size, the next item that all RC servo specifications indicate is speed and torque.
Speed is a measurement of the time it takes the servo to rotate a certain number of degrees. This has been standardized in most specifications to 60 degrees; In other words, the time it takes the servo wheel to turn 60°. The smaller the number, the faster the servo is.
For example a 0.12 sec/60° servo rating means it will take 0.12 seconds to rotate the servo arm or wheel 60°. This would be twice as fast as a standard speed servo that is rated in the 0.24 sec/60° range. A RC helicopter tail rotor specific servo will have speeds as fast as 0.06 sec/60°.
Torque determines the maximum amount of rotational force the servo can apply. This specification is measured in ounces per inch (oz-in) or in kilograms per centimeter (kg-cm). The larger the number, the more force the servo can exert. A typical standard servo will have a torque rating around 40 oz-in. A high torque specific servo can have torque values well over 200 oz-in.

Coreless & Brushless Servo Motors
Coreless Servo Motors
A standard 3-pole wire wound servo motor uses a steel core with wires wound around the core, this core is then surrounded by permanent magnets.
As you can imagine, the core and all that wire weighs a fair bit. When voltage is applied to turn the motor, it has to first overcome this weight to get things turning it is slow to accelerate. Once up to speed, it also continues to turn for a while when the voltage is removed it is slow to decelerate.
In a Coreless design, the heavy steel core is eliminated by using a wire mesh that spins around the outside of the magnets. This design is much lighter resulting in quicker acceleration and deceleration. The result is smoother operation, more available torque, and faster response time.

Most low cost and standard servos (analog or digital) use what is called a 3 pole electric motor. This is just a standard 3-pole wire wound DC motor the most common type of DC motor in existence. One step up from the 3 pole is the 5 pole servo motor. As you can imagine, two more wire windings will give a 5 pole motor quicker acceleration and more torque on start up.
You know by now the faster the servo ramps up to speed and the more torque it produces; the better it is for most applications. Well, improving the electric motor itself will produce more speed and torque too; coupled with digital technology, the resultant speed and torque are indeed impressive.

Vegas Trip. Cool pics
Just returned from a work trip. A lot of prep work and then a busy schedule during the week. The show is a lot of eye candy and neat attractions but make no mistake, there is a lot of serious business going on here. Though, it is funny to see men in suits and women in dress-skirts playing carnival games and munching on sample cotton candy.
We have blogs?!?!
Hi guys!
I just figured out after about 5 years of being registered here, that we have blogs! Awesome!
So a small introduction:
My name is Jason. I live in Los Angeles and I'm from the San Fernando Valley, although right now I am taking a break and living in Culver City. I think my interest in RC comes from my first memory being the intricately detailed free flight models my grandfather hung over my crib. I love building a little bit more than flying even, and I have a natural gift for it.
The first plane I "built" was a Zagi 400X and even though I couldn't really fly it, I let someone else try it at a park and it flew magnificently. He was amazed at how well it flew, since a few of his slope gliding buddies had tried building them and built them up too heavy and they wouldn't fly. I have since destroyed the Zagi, went through a few park flyers, and ended up with what I have now, my beautiful, super floaty Unicorn.
My current projects are as follows:
1. Get my Slow Stick in the air so I have something safe and docile to fly
2. Recover my Unicorn and restore it to it's former glory
3. Build a Boomer EX2... never had a glider before! DLG just looks fun
4. Build a platform for FPV... head-tracking is the coooooolest thing ever

Newest heli in the fleet
Walkera 4#3b double brushless!
Diversion
I have been working on a few other projects recently and have had diversions keeping me from completing the Prism rebuild.
The most recent project has been completion of a new Trex 600 ESP helicopter.
After flying a variety of helicopters over the years I have gotten the new version of the Trex 600. (I have flown both glow and electric ranging from Thunder Tiger Raptor 30's, Hirobo Shuttles, X-Cell 40's, X-Cell 60 Custom Graphites, to JR Voyager E's, Trex 250's, Trex 450se and se V2's).
The 600 is large enough for me to be able to see very well and keep orientation, a real plus now that my eyes are aging somewhat (thought that would never happen to me !).
Built as a standard kit, but I have replaced the Align electronic components, the Align 100 amp ESC does not have a very reliable reputation, and also the voltage regulators may be close to their limits with the servo setup I have decided on.
For power I am changing out the Align 650L motor to a Scorpion 4025 1100KV motor. Motor batteries are Hyperion 35c 5000mAh 6s packs. The Align 100 amp ESC has been replaced with a Castle Creations ICE100 ESC that also has programmable voltage 5 amp BEC and data logging capabilities when used with the castle Link. I have disabled the BEC for my application as the servo draw on this helicopter may be in excess of 5 amps in some flying situations.
The castle Creations ICE100 is a very capable ESC, having extensive programming capabilities to suit what ever flying application that could be desired. In this case I am using the helicopter programming that allows for a governor mode that seems to work exceptionally well. There are a wide variety or parameters in the programming avaiable when using the Castle Link. Additionally the data logging is an excellent tool for reviewing motor rpm, head speed, current, voltage, esc temperature, and many other variables. This allows for really being able to set up the helicopter and power system that will work for individual flying styles.
The flight electronics are based on JR and Spektrum equipment. Using a Spektrum 7100 heli receiver with a JR/Spektrum VR6010 voltage regulator with Hyperion 35c 2200mAh 2s packs for power to the flight electronics. Servos are JR DS8717's on the cyclic and a JR DS8900G for the tail rotor control. Gyro is a CSM SL720 Heading Lock.
The receiver has built in voltage regulators for the gyro and tail servo to drop them from what ever the input voltage to 5.2v (input voltage is usually 7.2v for a 2s lipo or in my case 6v for the VR6010 regulator). This allows for a variety of battery pack choices for the receiver and flight system. The VR6010 voltage regulator has an output of 6v with continuous current of 10 amps and peak current of 16 amps, more than enough for the servos and gyro in this system.
Initial tests and flights were last week and this week. Flights today were with the original stock Align 650L motor, which was adequate for gentle sport flying. I limited the flights to 3 minutes for data logging. The batteries and flight systems performed very well, with the main motor battery pack only using 1500mAh out of the 5000mAh capacity. This setup would seem to be very good for sport flying and mild acrobatics/mild 3D with 5 minute flights.
The data log shows the current draw was approximately 59 amps maximum, well within the limits of the motor and ESC. An attached JPEG file shows that data from today's 2 flights.
Pictures of the heli will be posted in the next day or so to show set up and equipment placement.

Cessna 182 nosewheel pants
I recently bought the Cessna 182 by Skylane from Banana Hobby... (1st mistake). This unit has a 55 inch wingspan. I am trying to find a replacement set of nose wheel pants. So far no one has been able to help me find them. Does anyone have any suggestions on where I can get these parts? The plane is useless without them since they hold the front wheel on. Ron

Plate tech-Tonix
Tonix is a polystyrene plate, with bits cut out and bits underneath added on.
I just wanted to see what a plate, with not much changed, would fly like. As a plate with ITC gear, it spun round and round and that was that. With underwinglets/landing gear the spinning horizontally slowed down. So then came some addressing to make it fly....and Tonix is the result.
A video would show it doing its thing, which I hope to take in the morning. It flies true and straight and is only frightening when direction input is held. Otherwise, it blips around nicely enough.
