Uploaded a few books now , some as old as 1910 ...
Thats 106 year old modeling books ...
Actually , if you think about it , aero modelling could be thousands of years old .. Free Flight in particular could be the oldest form of aero modelling bar none ...
How old is the boomerang ( ? ) Thats a flying wing of sorts , its free flight of sorts .. ( Just a thought ) But they found a model glider in the tomb of a pharaoh , yeah .....
So far ..
The Model Aeroplane Manual 1944 (?)
The Boys Book of Model Aeroplanes 1910
Model Aeroplanes 1934
Air Age Gas Models
Control line Model Aircraft
Keil Kraft Handbook 1963
Model Airplanes 1934
Model Aeroplanes and Their Engines 1916
Petrol Engined Model Aeroplanes 1937
Petrol Models 1945
Stunt Control Line Flying
Stunt Control Line Flying by R.H Warring ...
Air Age Gas Models ( 1943 possibly )
Control Line Model Aircraft ( 1949 )
As well a couple of Aeromodeller Annuals ..
I consider all to be of some historical importance , so felt the need to share .. I have some other publications I am going to share , one is about 100 years old and the other is 106 years old . Yeah !!! they actually had model aircraft publications back then .

Its taken for ever , but I thought it time to bind the i10 to one of my 450 helicopters ..
I thought everything went swimmingly until take off .. When the heli decided it had a mind of its own ..
The price for a lack of vigilance was 3 servos stripped ..
The fault lay with me for not triple and quad checking and checking again ... , and the other issue I should have picked up on was that the auxiliary and ail servo needed to be manually reversed at the receiver ( Yeah I missed that ) ..
So rather than spending a glorious winters day going through batteries , I spent the afternoon replacing servos and setting up the 450 all over again ...
Well , my reward for stupidity was a heli that was almost perfectly set up .. All that was needed was a little trim ( forward ) and the 450 hovered sweet ! .. Yeah I had to play with the rotor blade pitch curve but , sweet ...
I really like the i10 transmitter , for some strange reason quads and helicopters fly better with the i10 ( ? ) Go figure ...
At least I got in half a battery as the sun was setting and before it started getting dark .
And yes it has been a while since I have flown a 450 .. These days I just do the WL toys 959 with its larger battery ( almost 10 minutes of flight time ) .. That 959 is also bound to my i10 , and it flies sweet ..
So there you go , remember to check , check and check again , and when you think everything is good , check again ...
Oh well , its been a very long time since I have broken anything on a 450 , so I guess it might have been time to break something .
Still , would have been better to be flying than doing repairs ...
I have another 450 I want to bind to my i10 , I will have to be more careful I think next time around ...

It was time to mod my i10 and replace the factory battery with a 18650 ... Been thinking about how to do this mod for a while ..
So the plan was to put in a single 18650 / single battery carrier .
First thing is to open the case ...
Remove the 4 screws you can see ,
Then remove the rubber grips on the side of the case
You will now see two more screws that need removal to open the case ..
Now open carefully , the USB port / PC board , needs to be removed / unscrewed ...
Cut the red and black wires going to the battery bay as near the bay as possible ...
Now you have free access to the back of the case ...
Cut and fit the battery carrier ..
Fit the battery cover on , put a 18650 in the battery carrier and test fit it . then hot glue in place ..
The cover and battery need to be in place for proper fitting when you glue ...
I used hot glue , you can Epoxy after using hot glue .. Just make sure that everything fits and works as it should ...
Once the battery carrier is glued and ok , you can solder the wires to the USB / PC board ... You know , red to red and black to black .
You may wish to use some heat shrink tube ... Slip it on before soldering ...
Now you can re assemble ...
Dont use all the screws , two should be enough
Pop in a 18650 and make sure the Tx turns on ...
If everything is ok , re assemble and be happy ...
I trimmed the battery carrier enough for a flush fit on one side so that I could still put in a SD card .. ( if this is important to...Continue Reading
Pictured is my test set up . I used two ( Three actually ) USB wall adapters , the one in the picture being advertised as being a 1A model . The other USB adapter was advertised as being 2A , interesting little tidbit , each adapter is capable of supplying half the advertised current . Also I am using a Charge Doctor to monitor the current going to the charger . So with the 1A adapter that equals around half an amp , and with the 2A adapter about one amp of current . So that means I have a way of limiting current going to the USB charger .
2A adapter ( 1A actual ) Here we have all of 5watt to play with . Depending on the voltage state of the battery being charged , you could very well pump 5Watt into the charger ( less any losses ) . If you do your math , that is a potential charge rate of around 4+ Amps ( depending on how much power is absorbed by the charger ) and the actual voltage state of the battery . ( Yikes ! ) I did have a battery ( old ) that had a resting voltage of 0.6v , and I did use the 2A adapter and it did hit 0.97A on the Charge Doctor ... Single battery charge ( Yes it did charge quickly )
1A adapter ( 0.5A actual ) This is much better in my humble opinion as we have some 2.5Watt to play with . Even with half as many watt's to play with the potential is there to charge a single AA at potentially over 2A .. Charging 2 to 4 AA would...Continue Reading

Wow - Seems I havent posted on the forums for a while ..
Lets see :
Weather blows hard ATM , we have had some seriously bad weather this winter and lots of wind , an awful lot of wind ...
Went to school again to do my cert 4 in training and assessment ...
Was it 3 weeks ago we had a nice day , and I flew 3 of my 450's ...
I have been slack , lazy if you will , must be the bad weather , I have 2 heli projects and I should start to do some thing with them ... Like thread locking to begin with .
Its a chore , but needs to be done
Other than that , either or both projects should move rather quickly , and playing with the orange RX ( 3 axis ) can be done indoors ( to see if its capable of holding the tail at least )

Well after getting my Orange Rx with 3 axis gyro , I started thinking about what heli to drop the gyro into ? I was on ebay and saw this frame kit , for $15 shipped I figured it was worth a look see ..
Frame came today , and its been bolted together using two sets of left hand frame panels , thats ok , I was planning on doing that myself as one side is cheaper than the other to buy and ship ( Strange but true ) .. + It will make no difference to how the heli works or flies , though a keen eye may pick up on the fact its assembled from 2 sets of left hand panels ..
Came with canopy mounts / servo mount pads / anti rotation bracket and a complete frame ... For $15USD shipped , this will become the X-heli to test the Orange 3 axis gyro Rx ...
I got myself the Orange 3 axis gyro receiver ( spectrum ) as it really is relatively cheap , and as can be seen , its not overly large for a Rx with a built in Gyro .
Now from what I have seen ( youtube ) these sort of work well , and ver1 and ver2 did show some promise , so when ver3 became available , I thought it time to put my money down and get one ..
Now my main goal is to see if it will work ( receiver ) in a 450 helicopter ..
Since these receiver / gyro's were meant for planks ( RC Aircraft ) I want to test it in a flybar 450 , and see if the 3 axis gyro has anything to offer ..
Certainly be interesting to say the least ..
I will see if the Orange Rx/Gyro can hold the tail first ( looks like it will work with a regular Gyro ) , and then with a regular HH Gyro ..
And then see how much Elev/Ail can be dialed in on the Gyro
Oh well , something interesting to do in anyway ..
The guide is primarily for Noobs [ if you are already flying ] you most likely dont need it . And please , this is not a how to fly guide . Simply my attempt to ease any apprehension Noobs may have about the assembly process .
If there is enough interest , the next book might be on Flight Stability :
Setting up the heli to be stable :
Cover such things as the Gyro [ several of them ]
Maybe the 3 axis gyro
Flight stabilizing solutions such as Flymentor
And cheaper options , weighted blades , blade weight , Flybar weights etc, for Noobs of course since experienced pilots dont need help , its us noobs that need all the help we can get .
One of the things I dont understand ?
Why would a beginner set up a heli for 3D ???
Beginners need helicopters to be stable , solid platforms that provide the pilot with as little excitement as possible , once they progress , they can tune the heli to be more exciting [ responsive ]
An overly responsive [ exiting ] helicopter will most likely cause as many crashes as a poorly assembled and set up one [ possibly more ] for those just starting out . And possibly drive the individual away from the hobby , and we cant have that , can we ?
