Spektrum AR7000 Beware!

[drkilljoy]

I saw there is a technical service bulletin on Horizon Hobby for the AR7100 regarding antenna detaching on the receiver board. This could be similar i suppose.

My AR7000 is already with HH for repairs. i experienced glitching in the air but was able to land safely with the glitching going on. In my case the LED on the receiver was flickering randomly. This was on an electric model with no vibrations going into the airframe. Lets see what HH says.

I think it's time to inspect my antennas.

Thanks drkilljoy I found the same article last night right on spektrum's website and they posted it after I got my receiver. http://www.spektrumrc.com/Articles/A...ArticleID=1811

That is for the 7100, and 7100R, not 7000...

Well none the less my antennas haven't been falling out on anything but the 7000 series receivers, lol I don't know who was on the assembly line for mine but they obviously wanted to screw me over! For anyone who doesn't really know what the smart fly does the bus load on a AR7000 isn't enough to get the max voltage to your servos heres a video I'm running 5 7955 and one 925mg for the throttle this video is from TBM and I think the AR9000 might have a high enough bus load of like 75amps or something which should be enough but I think the the 7000 is only 35amps I could be totally wrong but this is what I've heard.

if your really worried about power issues. this is your best option.
i talked to a tech at horizon a few weeks ago and they said a ar7000 can handle all 8711's. it has a 50amp buss.

If theres no way to add foam below the receiver and mount it to the Smartfly Expander, thats not a Spektrum receiver fault. I have a AR7000 myself, and have had 0 issues, with plenty of flights on it. I don't use any type of power expander or anything. Waste of weight and money to me. But thats just my .02 Seth

You use 1/2" foam on receivers for your electric planes too?

My 48" Extreme Flight Extra 300 EXP is the largest airplane I will not use foam on my receivers. It still has the soft velcro stuff on it. ANY electric/glow/gas airplane larger than that, I mount with 1/2" foam.

Exactly. If you're concerned about power issues, why not get a receiver like the one in the link above? Then theres no need for anything extra besides the receiver itself.

1. The voltages still aren't regulated plus I use fromeco 2600 lipo's 2 for the rx
2. The receivers voltage isn't separate where with smart flys its only 5.0v and the servos are 6.0v
3. Channel matching the smart fly requires less y harness and other ****
4. Its cheaper to get a smart fly than to get this receiver, because they aren't grossly expensive for what your getting.
5. I live in Canada and that unit right there would cost me $300 plus I would still need regs and a ignition kill
6. For $232 Canadian I can get a smart fly system sport plus which gives me regulators, and opti kill basically everything from #1-3
If your not running lipos they have the same thing without the regulators but its only $200 Canadian which I don't know how much would be In American.

Hopefully this clears a bit up about why smart fly is cheaper and better IMO than what you have suggested.

[jamesrxx951]

that unit is only rated for up to a 85cc bird.so if you are flying just that sized airplane you do not need no fancy power systems or anything like that. i flew my 50cc yak with no issues with my ar7000 reciever. i since up graded my radio to a 9303 and decided to get the 921 reciever. still no issues. a plane that size will not require anything like that. just get some good regs or switch over to a123's even more simple. that reciever will last you for any plane you want it in. you want 30% it will do it you want a 43% no problem. i have seen people fly with no issues a 35%er with a ar7000. all that bling is just added weight, possible failure points, and just not needed. and you mentioned that the reciever voltage is only 5v with the smart fly im pretty sure jr has a internal reg if it is needed inside. i just bought mine at chief aircraft for $189 american. not sure what the exchange rate is. a friend of mine that is very well sponsored and known and im sure just about everyone knows him flys 40%ers just lipo's,reg,reciever,to servo's.

Why do you need seperate receiver voltage? I believe Spektrum receivers can handle 9.6V. No idea what this is needed for.

Ok, so you can use it to match servos...just like a matchbox or y-harness...y-harness is much less weight.

Okay, so the Smart Fly is cheaper than the 922, but if I'm not mistaken, you gotta buy a receiver on top of it!

You can always go for the AR9100, $20 less than the 922 (US Dollars). Thats just over $300 Canadian, for the receiver/regulators/y-harness's AND a 9 channel receiver.

Just over $300 for your Smart-Fly set up (only with a 7 channel receiver).

Exactly.

I fly all my 40% and 35% stuff without any power expander stuff. No issues. Why? Its not needed. Power expander is just 1 more possible failure point.

I use A123s, so I'm even lighter! Battery -> Receiver -> Servos. KISS! (Keep It Simple Stupid Method). Much less to go wrong in my setup.

Just the way I roll.....or fly. But thats me. Do what you want to do.

i've seen you freestyle seth and im pretty sure your pulling alot of amps through your reciever.

[JoeAirPort]

Same here, I don't like all that extra crap. It's just money, weight, and worse, more failure points.
