Micro Radio sets.

http://www.hobby-lobby.com/hitec.htm

(See model HTR48725)

Here is a good one,or a cheaper way perhaps would be to buy a standard Transmitter,a Jeti mini Receiver with BEC ( Battery elimination circuitry) and three/four micro servos,have a word with Midland Helicopters,Hinckley for a good deal on the Jeti and servos,you will need a lithium 2 cell pack and a compatible speed controller ( lithium batteries should not be run flat and these controllers cut off the motor when a certain voltage is detected ) so to re-cap you will need-

Jeti BEC Receiver ( RX)

A standard 3 to 4 function Transmitter

3 to 4 Micro servos

P-Extra-Air 14 Electronic Speed Controller (ESC)

Lithium 2 cell pack 7.4 800 mamp

Dedicated Charger for the battery

State these when you ask for a quote,dont forget that they can be swopped from model to model,I use a module board which screws into different models,all you need to do then is connect up the linkages to the controls.

Dont worry the insructions are self explanatory,and above all you will get unlimited support here when screwing in the radio etc.

Wonwings diary-UAV,More plans for Predator.

The Air Force National Guard have big plans for the Predator mission,after much speculation about the future of the unmanned aerial vehicle mission to be split between the Grand Forks and Fargo bases, the Pentagon has set the record straight.

The Air Force and National Guard agreed on additional details of the Predator UAV mission after a round of talks at the Pentagon last week,the vice chiefs of staff of the Air Force and the Army signed the agreement June 20. The agreement is a significant step in ratifying the Air Force's plan to place a family of UAV's in Grand Forks and is good news for Fargo,It is welcome news, and a great victory for North Dakota.

The Guard and Air Force officials also agreed to purchase a joint cargo aircraft to be shared between the services, though they wouldn't specify

which aircraft.

The Air Force and the Army were independently looking for options for a light cargo aircraft to fly airlift missions in the theatre of operations.

Fargo's new cargo airplane will be used to transport UAVs.

Representatives from the Air Combat Command, the Air Force department in charge of UAV operations, participated in a working group at the Pentagon June 13. The team of experts examined different options to expand formal training for Predator operations one of the roles that Grand Forks Air Force Base is expected to play in the future.

Conrad has said that Grand Forks could become a hub for new UAV technology being tested and developed, such as the next generation of unmanned bombers.

Northrop Grumman is developing the RQ-4B, a larger and improved version of the intelligence-gathering Global Hawk.

An advanced version of the missile-carrying Predator also is in the works.ACC is slated to receive 203 Predators,some of those will be deployed to the Guard.Grand Forks initially is scheduled to receive eight Predators in 2009 and six to eight Global Hawks in 2010, but those numbers are not definite.

The details of the Grand Forks and Fargo missions were embedded in the Air Force's Total Force Integration program, which lays the ground rules for military strategies and acquisitions. Under this program, the North Dakota Air National Guard's 119th Wing was assigned two missions at Hector International Airport. Those missions are flying an unidentified joint cargo aircraft and operating a Predator UAV ground control station.

The Guard will create a new maintenance unit at Grand Forks Air Force Base that will support Predator launch and recovery operations. The new maintenance squadron also may be asked to support Global Hawk UAV operations once those aircraft arrive on base.

Wonwings diary-Foam & Balsa log construction.

http://www.smallflyingarts.com/Current_Content/Article_3/fuse_carving_1.htm

Well I am going to let you see someone elses excellent approach to carving both, foam and balsa log construction today.

We have discussed this type of construction many times here,and was just about to do a tutorial when this came to my notice,so why re-invent the wheel ? it is a first class article which highlights all of the things that you need to now,just look at how thin the walls are carved,the secret to lightweight construction,and note the lovely clean modelling at the end with hand decorated wings and fuselage,it is a messy process best done outside but well worth the efforts to get the shapes that you want.

Wonwings diary-TV Drama 'Coup'

Did anyone else see the TV drama last night called 'Coup' ? the true story evolved around the intended take over of an oil rich country by UK businessmen,the elaborate scheme which involved Mark Thatcher who flew helicopters,went terribly wrong with most of the people finishing up in awful prisons being caught in the act,there was a fair bit of aviation activity in the film,I noted the following-

Mark Thatchers Alouette II helicopter,some interesting aerial shots from the cockpit,low level flying in a Beech 200 ZS-LFU at 20 feet above the ground to evade radar,two Dakotas,one a turboprop ZS-CAI & ZS-AJI,Boeing 727 N4610,Learjet ZS-BXC,Antonov AN.32B which suffered a dramatic bird strike on take off and aborted,a Tiger Moth,a DC-4 in the background,and I am sure they used some shots on the ground of one of the Air Atlantique aircraft ?

I liked the quote from the film when they opened the hangar doors to see which aircraft were being used 'Are you starting a museum' ?!!

Strange bitty storyline could have been written better,but the flying kept me in front of the screen.

Wonwings diary-Rare item comes up for sale-Me.163 Rocket Motor

http://losangeles.craigslist.org/wst/car/177563355.html

This appears to be a genuine Me.163 Liquid Rocket Motor,if you have a spare $5000 then it could be yours.

Quite a find these days.

[Guest]

I once read a book when I was a cadet about the experiments with these rocket planes. I might still have it tucked away somewhere.

The two fuels were called Z-Stoff and T-Stoff and were so unstable that if it was not all dumped prior to touching down there was a good chance the aircraft would blow up on landing. Consequently you did not get a second chance at your approach.

Enemy or not I still have a great deal of admiration for test pilots such as these.

[wonwinglo]

That sounds like 'Rocket Fighter' Richard,a classic book.

The two substances were a highly explosive catalyst,the fuel lines were toughened glass the only material that would not melt,if Komet back did not wreck your spine due to the rocky skid landing,then unburnt fuel that formed a residue in the lines would explode as it fused together,they climbed like a proverbial home sick angel,and landed like a brick,there was no chance for a go around.

Wonwings diary-The true price is what it is worth & those prepared to pay it.

We get a lot of enquiries as to what is the best price that I can expect for this and that,if you have ever been involved in the antiques trade then you will soon realise that what you buy does not always zoom out of the door fast,far from it,many items pass from dealer to dealer,the lemons of the trade as they are called.

Better to have a buoyant fluid market where money changes hands rather than something stuck on the shelf.

So bear this in mind when you need to sell something,here are some wise words from Jeremy which says it all and sums it all up-

One drawback to trying to put a price on a particular item, especially older collectibles, is that there isn't a price list. Last week your particular item may have sold for over $1000. Assuming it's a very popular item and appeals to a very wide audience, you might expect the same amount this week. However if the item is more specialised then all you know is that at least one of your potential buyers who was willing to pay a good deal is probably no longer in the market. And the others were not willing to pay that much.

Some models can be in great demand for a time and prices shoot up. If the demand dries up the prices will fall very quickly.

So the simple answer to your question is your kit is worth exactly what someone will pay for it today!

If you can set a price in your mind below which you prefer not to sell, then your ready to offer it for sale. If not, then search e-bay every now and then and see what prices are being offered. Since the item is not that common, this will take a while. Eventually you should get an idea of what's reasonable. And bear in mind what's reasonable to a seller, seemsoverpriced to a buyer!

Wonwings diary-The Hiller Flybar



Anyone watching the last of the 'Heartbeat' TV series on Sunday,will have seen a very historic (and correct for the period ) vintage helicopter which was used in the plot being flown between tress and landing on a road.

This was in fact a nicely preserved example of the Hiller UH-12 which is based in Leeds.

We have discussed the unique control system used in this helicopter before,but until now did not have a decent photograph to show the patented Hiller Flybar system used with great success by both Hiller and Bell.

So what is so special about two little paddles set at right angles to the main blades ? well when Igor Sikorsky built and flew his early helicopter designs he encountered a problem that can be easily seen in early movie footage of him flying,the helicopter whilst under control was flying like a bucking horse,tiny movements of the collective controls (rotor blade pitch and throttle together) were used,however he was still having problems in flying the helicopter smoothly.

So what was the answer ? well what it needed was some form of dampening so that the direct loads from the rotor blades to the stick were cushioned,a genius called Hiller set to work and started to build tethered model helicopter designs to study the problem,he tried everything and has is usual with these things it was a simple fix to the solution which proved best,he fitted another small set of blades at right angles to the main ones,these were called paddles,by experimenting with various lengths he arrived at a compromise where the load was adequately transferred from the main blades via the paddles, these are set at zero pitch as shown in the photograph above,the difference that they make needs to be appreciated.

It is true to say that model helicopters would be virtually impossible to fly without them,having tried it I can testify to that.

Modern helicopters with both low and high inertia blades, which flex in order to allow for the retreating and advancing blade movement, are mostly used today,but even that system needed to be sorted out before successful helicopter flight was feasible.

We owe a lot to Hiller and his flybar system which enabled fully controllable helicopter flight.

Wonwings diary-U.S.Airforce to buy Korean training aircraft ?

A U.S. Senate committee has directed the country's Air Force to study whether it should buy South Korean-made aircraft to replace its aging and inefficient trainer fleet.

Currently, the South Korean government is also looking at the United Arab Emirates, Turkey and Greece as possible buyers for the trainer.

In a directive dated May 9 and attached to the National Defense Authorization Act for fiscal year 2007, the Senate Armed Services Committee called for a study to determine the suitability of South Korea's T-50 training aircraft to replace the current T-38 models, the report said.

The committee also called for a suitability study for the U.S.produced T-45 trainer.

The U.S. Air Force plans to spend $1.5 billion to maintain its T-38 fleet at a cost per flying hour that is double that of the T-45. The cost of developing a new replacement trainer and system is estimated at $2 billion.

Accordingly, the committee directed the Secretary of the Air Force to conduct a study that would determine the suitability of the T-45 and Korean-built T-50 training aircraft to replace the T-38,' according to the report.

The study should focus on cost of procurement,operating costs, the

availability of a complete training system, and developmental costs, the committee said.

The committee asked that a report on the study results be submitted by March 15 next year.

A diplomatic source in Washington D.C. confirmed Seoul's ambition to sell its T-50 trainers, the report said.

Kim Sung-il, South Korea's Air Force chief of staff, visited Washington in May to discuss a possible deal. We are making efforts through various channels, a source in Seoul was quoted as saying.

T-50s are on the expensive side because of their capabilities, he said.

Developed by the Korea Aerospace Industries, they are tagged at around $20 million apiece.

so when are we going to replace our tornados? aka "flying coffins"

[wonwinglo]

***Thats the problem with any high tech machine,knock out the electronics modules and trouble starts,for example the old B-17 may have been very basic but it got home shot up to pieces.
