futaba 9c upgade to specktrem vs FASST

[midnightdreamersr]

i have been flying a futaba 9c for about 7yrs now and fly all my giant scale and warbirds with it. i love this radio and want to keep it although i would like to upgrade it to 2.4 so i limit my chances of getting shot down over someone turning on a radio. i have never had a "hit" flying 72mhz but better safe then sorry. i have called both futaba and specktrem, they both have an upgrade for the older 9c. i have a friend that but a futaba 2.4 fasst oh his 40% bird with a power box and almost lost the plane due to the reciever becoming debound from the tranmitter. after his lengthy call to futaba in his words they said that they were having a few cases of this happining and should take out the powerbox and that should solve the problem. not liking the answer he went back to 72mhz. i called specktrem and they hands down told me there would never be a problem with that set up if i put there udgrade in my transmitter. so not wanting to beleive what a manufacture told me i thought i would put it up and see what real people were or are doing and what they are running in there planes and see if anyone else was having the same problems. thanks for the help

They both work.

IMO the reciever selection from Spectrum right now makes them a compelling choice. Anything from foamies to 9 channel (though you could only use 8 with the 9c)

What I like about Futaba and the Fasst system is that there arent 10 different receivers and a six channel receiver will work in any size plane ( unless of course you need more channels ).
I am not sure as to why the Powerbox would make any difference as far as the link becoming "Unbound".....

I dont want to sound pesamystic here but how did the radio become unbound and how did he *nearly* loose it.

If it lost the GUID as was the case with the early 6 and 7 channel units it still flew perfectly until you found someone else with a Zero GUID. Then you had problems of course.

But loose the bind and nearly loose the plane sounds a little hard to fathom.

Dont worry, I beleive you and am not calling you out but more on what really happened would be great.

I have a Futaba 9 also. I'm going to use the Spektrum conversion because it looks alot better with the 9C. The FAAST conversion has the antenna on the back of it... The Spektrum has an adapter to plug the 2.4 antenna right on to the orignal antenna hole. Plus, Spektrum has that new powerbox system coming out, and you can get those extra antenna things they have... I'm no wiz about 2.4.

he nearly lost the plane because it was on the ground when it went to full power and he had no control of the plane. he tried to kill the motor with his ignition kill and nothing happened. luckly for him there were a couple guys at the field that came to his rescue and shut the switch off and killed the motor. they looked it over and nothing worked. that was after 6 flights on the plane.

Holy snappin agitators mate.

That would scare the hell and everything else out of you. So he had six flights that day on it or was it the first flight for the day. I figure it takes some serious gremlins for the bind to disappear as it would be stored in some sort of non volotile memory.

Keep us posted on what the response is please and what they say happened to cause this.

I suppose if the Rx quit totally for some reason that would be one scenario.

[BR289]

Yes, I too am very interested in the findings....

kiwi,

he had flow it 3 times that same day before that happened. and from what i understand he told me after a lengthy phone call to futaba, they told him that it was a problem with is power box and that the fasst recievers werent designed to go through it. take it out and it would work fine. he basically told them to stick it and went back to his previous working 72mhz system, now all is well. at least with the plane

thats why i wont to know if any other pilots have had this problem running a fasst system or a smartfly power expander or if he just had bad luck. im not willing to put this in my new plane just to have it fly off or crash do to a problem like this.

Just a point here about Failsafe -
I've got a 9c thats been converted to 2.4 at the Factory
I'm led to beleive the Factory Setting is for Throttle to go to Idle at Failsafe Condition.. However I had reversed the Throttle Servo direction.. yep you guess it - Full throttle when no TX!
Luckily Heard about it happening and reset Failsafe before next flight
Phew!
