|Thread: 2.4 GHz Power-up|
I have a DX6i and the control surfaces on one model deflect when Rx is switched on and then go back to neutral, apparently the cause is that the Rx puts power to the servo's before it sends the position signal, some servo's don't move when you do this, others go to one end of their travel. Which is probably why some people see it on different channels.
|Thread: Spectrum DX6I|
Flown planes with my DX6i with 2 x AR6200's and 2x 6100's to limit of visibility with no apparent problems and I have Tx set to EU lower power mode.
In my EDF's and Twin Jet the RX (6100's) have been between the battery and ESC or between ESC and motor, reading a recent letter in RCME this shouldn't be ideal but no problems experienced.
Even had Tx battery alarm go off and when I landed Tx battery was down to 3.7v but again no control issues.

Easy Star from Multiplex also comes recommended by other teaching themselves to fly, comes in kit, Ready for radio and ready to fly.
Note no connection with the above shop, they just came up in google.
|Thread: I keep crashing|
Not sure what ESC you've got but if it's not the switched type it might be overloaded on 4 servo's but in which case it would be getting hot.
Have you checked the obvious causes, i.e. linkages being too flexible allowing control surface to be blown back or even servo's not being powerful enough.
I have 6 servo's on a larger electric but it has a 5A SBEC built in and so far no problems, and two of the servo's are on some fairly large flaps.
Try holding the control surfaces and see if the servo can move them when you try to restrain them a bit.
|Thread: How much power for EDF?|
|You can always throttle back if you have too much power, but not the other way round.|
|Thread: Mode 2 tranny and ar 500 rx help|
From what I've read about the AR500 it has a built in Y lead so the the aileron servos are just driven from the one Tx channel. You would have to plug the servo's into separate channels and then use the free mixers to do what you want, but I'm not sure how easy that would be to set up. Even on mode 2 flapperon/spoilers will only work if you have a 6 channel Rx.
Mode 4 eh, the only Tx manufacturer that caters for that that I'm aware of is Multiplex, the Cockpit Sx comes with modes 1 thru 8 as standard, but only on 35 mhz you'll have to wait for the 2.4 version I'm afraid. But setting up spoilerons etc is very easy even in mode 4.

Timer on Tx is set at 11 mins and uses about 80% of the battery.
|Thread: Any reason why I shouldn't|
With the Y lead both motors will run down at the same time, if you put separate batteries on each motor then if one battery is less charged than the other then one motor will develop less power at the end of the flight.
But if your Lipo's are the same brand, have the same number of flights and you don't fly until the LVC activates then having separate batteries and motors would seem fairly logical and cuts out the extra joints.
|Thread: New DX7 SE|
|Maybe the new Tx won't buddy with an older one due to the faster frame rate, so they decided to leave the function off.|
|Thread: So many TXers|
|If you are looking for a 35mhz set, you could look at the JR and MPX synthised sets, you wouldn't even need to change the Tx crystal. Just about all programmable sets have both fixed wing and heli programming, but some have more advanced features than others.|
|Before the DSM vs FAAST arguements start, they both seem good systems, I have a Spektrum DX6i and there is a Futaba 6 EXA and FF7 2.4 used regularly at our club and so far no problems. So I'd say go with the one you like best.|
|Thread: Fleet radio gear|
I have a set of instructions somewhere for the XP/FM set, but as you are using it for a surface vehicle I assume its a 40 mhz set not the 35 mhz set, I know fleet used to sell quite a few 40 mhz sets for boats and also to robot builders. I'm not sure if these also had some different features, I can't see how coupled aileron and rudder would work on a boat.
Having said that the fleet systems are very simple, all the reversing, throw adjust and mixers are done by mini switches and adjustable pots inside the rear case and they were all clearly identified on the XP/FM sets.
The only thing to watch if you have got a fleet Rx is that the servo pin allocations are different as has been stated above.

|Do a search on cadmium poisoning and you'll see several articles come up on workers in battery factories being poisoned.|
|Thread: New charger|
The Ultramat 16 is only 50w off the mains (80w off a separate battery). You could charge a 6s at 2A off a 50w charger.
I bought my 12v power supply from Maplins and run several chargers from it.
I have one of the Turnigy chargers and its pretty good, for the money it's outstanding.
|Thread: DX6i Binding|
John rebind the Tx to the Rx and it will then remember the low throttle setting, That's the only failsafe on the DX6i, throttle to low setting all other channels stay at last good position. But if you change the low throttle position then you have to rebind for the Rx to "save" this setting.
Just one last thing to check is that you do have the throttle and collective in the correct Rx sockets, wouldn't do to go to max negative pitch and leave the motor running at last setting in case of a failsafe event.
|Thread: ASP FS91AR|
|My ASP 91 FS does 9,200 rpm on a 14 x 6 on 10% nitro. I had some problems with mine cutting out initially and it does seem sensitive to the fuel used, but in the last 3 models it's been very good.|
|Thread: Low voltage protection|
I think it depends on the plane with my E-Flite Beaver most of the flight is at half throttle or so, I only use about 3/4 for take off, so you don't see the high load on the Lipo's.
What i do is measure the full throttle amps, set the timer to give about 90% of the mah out of the battery at this setting and then adjust the timer after a few flights and I've measured how many mah have gone back in to give me an idea of the actual mah used per min.
I started with the timer set at 6 mins on my Beaver and its now set at 11 mins and uses about 80% of the mah available. Whereas my Fantom started at 6 mins and has stopped there
|Thread: DX6i Binding|
|John it's maybe that your ESC needs calibrating, try switching it on with the Tx at full throttle and then come to idle so it learns the throttle throw. Make sure heli is restrained or blades are left off for this.|
