CLOUDS AXN details cabin layout modified.

I'm exposing some details of my model and cabin layout that I think is always a good buy with others.

Here you can see the complete model with the radio. Flysky 9x with a firmware module ER9xfrsky and frSKY9x with telemetry.

Here we see in detail the support for the video camera, and the ventilation holes of the cabin to generate a stream of air to cool the electronics.

Here we can see in detail the reinforcement of the tube and support for the receiver antenna, when I can I change it and I put an antenna itself, from a WiFi team.

In this photo we see the belly of the plane reinforced, and the wires of the servos for the wings, which led them out, for comfort ... and to not be moving in flight, I've put a sort of gutter, not yet I tried this last we will see that this works ... in the tests look good. .. after several shocks were still in place.

Reinforcing tail is necessary because not having wheels when it lands it does direct the fuselage, I have also included a weight of 3Grs to balance somewhat the model, because a lot of weight in the trunk. Also offers more strength and stability at the helm.

Finally we can see the cabin layout, not much space and the first change I think I take the tail servos out and do a walk as God intended. You can see the original controller a 20 Amp (I am in doubt whether to change by a 30 Turnigy), the receiver and next 3Amp regulator UBEC, and he did not trust much in the BEC regulator and preferred to take it out. I've done the calculation and all servos working at the same time but the receiver consume 750mA, and the receiver in standby waiting for orders consumes only 80mA. I have not been able to measure consumption with the engine to stop, as my multimeter only goes to 10 Amp, I have to get one with a penguin and to measure the drop in 1W resistor.

Well this is my config, when you make changes I will put here.

Flysky 9x with firmware er9x flap configuration, AirBrake, fast spin & thrCut.

Today I will describe a configuration that I made to my model an AXN Clouds ... which with a radiu Flysky9x (Turnigy 9) can do many beams,.

The first thing we do is a simple cut or called ThrCut engine, most of all for safety and inadvertently not a asceleron the model and have to look in another neighborhood. Or worse ... give me a blow with the propeller.

This is done quickly including a CH3 additional mixer in my case is the engine control THR.

Staying well.

THR 100% CH3
MAX R-100% RUD

being in detail:

Source MAX (data source, in this case we just want something fixed)
Weight -100 (the value we subtract the THR when you run this MIX)
RUD switch (switch to activate the change, in my case is the RUD for convenience but can put any other)

without changing anything else will get the expected result.

Now we will with the FLAPS, both for this and for separate air brake servos need to work independent manner, using another channel for this. The rest is easy because all you have to do is add a% to turn the ailerons when a swicth, about the same as with HRT, we create an additional MIX each of the wings, with 30% is sufficient .

my channel for ailerons I have them in CH4 and CH5 are each servo in each wing.

AIL 100% CH4
+ -30% MAX GEA
-100% AIL CH5
+ -30% MAX GEA
Additional details of the mix is:
Source MAX
Weight -30
Switch GEO (this is the name of SWITCH, I feel comfortable in that place)

For air brake things get complicated because in addition to wings we involve the tail lift.

as this seemed rather put the first two positions in the wings up to 30% and low tail lift 30% ... and the second highest proportion is 100%. Being the following.

AIL 100% CH4
+ 100% MAX ID2
+ 30% MAX ID1
-100% AIL CH5
+ 100% MAX ID2
+ 30% MAX ID1
Elevator
100% CH2 ELE
+ 30% MAX ID1
+ 100% MAX ID2

This will set the brakes ...

Finally we will turn the help ... which is basically when a switch activate the rudder follows the ailerons, causing the rotation takes place more quickly. (Only recommended for people with experience in flight).

This is even easier. Because who will control the rudder control will be spoilers, we perform the following.

100% RUD CH1
AIL ELE + -25%
Inside looks:
Source AIL (the control will be the same spoilers)
Weight -25 (I think this is enough to improve the turn)
ELE switch (the switch that controls whether or not this applies)

Well here you have a video about it I hope you find it useful ... then put a step by step as with the console in hand.

Any questions will be welcome.

Turnigy 9x & Flysky 9 with firmare er9x

As I said in my previous post, I futaba radio has been little interference as well as some that I found on the field, so finally I caught a Flysky 9x, which has 8 channels MPP, and transmission at 2.4GHz .
This station is inside detail that has an ATMEGA64 processor which can be programmed with open source firmware and with infinite possibilities.

The radio is this: It has cost me 62euros home since and has been slow in coming to China more or less 14 days. Customs has not stepped on and is therefore not cost me more than the bill.

After some investigation I found the pinout to make the firmware upgrade.

Here some of my RADIO fotor opened and modified.

We made some changes that I needed, I have a switch for the beeeep so annoying (short speaker replacing a red LED), and I have included a screen (temporary until you reach the final) to include the LCD light (absolutely necessary)

I also left a connector soldered to the motherboard to set it whenever you leave a new version.

The last modification made is to adapt to the transmitter for resistance than necessary to remove the radio to use in a simulator.

Also as I've replaced the battery with a lipo, I would put a diode in the power to prevent short by reversing the polarity.

First backligth switches LCD and buzzer.

Using this backligth an old LCD I could install it temporarily until I get my order in HOBBYKING
Being as follows ... remember it is temporary ... I do not accept criticism ... :-)
Well the next step was the resistance and the diode on the back panel in order to use the simulator without having to remove the module (just do not recommend that you have between your legs 2.4Ghz can not be good), and the protection diode . the resistance is 1Kohms and the diode is a single 1N4001.
Finally I have included a connector to program it as often as desired, of course, opening the box as it is hidden inside.
Maybe you do not notice it where I welded, so I include an image from another website to have more vision ...
I do not remember where the kick but has helped me ... thanks in advance who created the image.
The procedure is easy, you buy an AVR programmer that supports AVRDUDE http://www.nongnu.org/avrdude/
AVRDUDE downloaded the program is for all platforms, I've done on Mac and it worked great.
Connect the controller to generate the transmitter and the station produces an error message of SWITCH, which we see whenever we turn on the radio with one of the switches in the ON position (up, looking at the front console)
with the radio on "SWITCH ERROR" and the controller connected to the same proceed to charge the firmware, always keeping before the last, what will happen is always recommended.
The version I've used is to ER9XfrSKY (and I intend to put telemetry below and one of these modules FRSKY)

First we must consider that we acquired programming and programmer, knowing this we can go ... in my case the developer was a USBASP highly recommended and cheap, about 6 euros as at home,,, can be found on ebay. And the bus that we will schedule an ATMEGA64.

The command to use is fácil.avrdude-c (name of developer)-p (name of the chip to program)-B1-U (type of memory to read): r: (name you want to give the backup): RLA R and W is for reading or writing course. And the fuses-B1 and U are read to verify what the procesador.Hago a receipt of the current config.

AXN Clouds Flier new entertainment.

A few days ago I asked for a plane of EPO did not have much confidence, but I have finally convinced to try it, I was always the idea of ​​balsa wood and aircraft engine combustion in the subject of flight time ... but a friend convinced me to catch me in GLIDER as they may be planning and use of the motor is greatly reduced ... extending the battery life up to 2 hours of flight.

The first aircraft, a glider as I said is a glider with a wingspan of more than a meter, in this case 1290mm.

The picture I have drawn from the HobbyKing page if you have patience is a good place to buy.

I include a photo of mine.

So far I have not caught one since even RADIO Futaba me I have the previous model, but with 4 channels to me recently.

Here a video of the first flight, I almost stamped with a friend ... :-)
