Spektrum AR7000 Beware!

[leepord geko]

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.

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.

[3DHobbyShop]

That was the one thing I didn't like about that power expander (everything else IMO is perfect on the SmartFly) is that if you mounted everything as directed, it shook the crap out of our Rx. I tried some different thick foams to mount (because obviously it looks very cool to have your Rx mounted in the center of your expander, right?)...but now that the AR9100 exists, problem solved. No more regs. No more buying switches. Done. Love it.

And its all 8711s

It pulls plenty, and believe me, if I were to have an issue, I would have had it by now!

Alright I'm going to rename this thread on how to over hammer your 50cc with redundancy and still wreck your receiver

[Ballistic1]

looks like someone tried to fix the antenna lead . The circuit board uses
surface mount technology which are assembled by machines which make consistant solder connections
all done at the same time in a special oven called a reflow oven

just my opinion

What you say is certainly true for most of the components but I suspect the actual antenna leads
are hand soldered after the rest of the main board is assembled..

Well I replaced it with the ar9000 and so far its holding up personally I just think it was a bad receiver and you get some of those, I don't think vibration was the problem because the smart fly board should have failed then as well, and your plane doesn't vibrate all that much in the air to begin with.
