Just ordered JR's 9303 2.4 GHz

[niccolo98]

Hey Guys,
it finally happend to me. I took the leap from 72 mhz(my old 9303) to 2.4!! I will use 2 9 channel DSM recievers in my Dalton Aviation 35% Extra 260. I will let everyone know how it went for me, but I am expecting good results, (hence the me putting it in a 6000$ plane)!! Any tips on setting it up would be greatly appreciated.
Best regards,
nick

Would you mind telling us how you are wiring it?, Side side or intermixed?

How are you powering it?

Are you planning on 4 receiver setup for each 9000?

My opinion: If you want dual receivers use the following:

2 9000's
1 36 inch remote receiver, and one 24 inch remote for each receiver.
1 datalogger for each receiver.
A123 batt systems, doesn't really matter how big, you could run 2 4600 packs with twin wires off each.
Intellect 1400 battery ignition or A123
PLace one receiver midway back on each side of the fuse in the tail
place the other remote closer to the top in side the canopy 90 degrees to the other

Elevate the receiver away from things in the middle of the plane. Or place the main receivers high in the canopy area and the remote low. either way.

once you get er all working.....go out and do a range check at 150 feet instead of 100. If everything works,.....have a couple of guys rotate the plane around like its flying, looping..rolling...etc.....be careful here it is a dalton $$$$.

THen set the radio down where you are, and walk over and check the data loggers.

When you fly the maiden, do it again. You should have no drops/losses and few fades. If one receiver has many more than the other, adjust placement until you are satisfied. I would say less than 20 fades for this test.

Key to this? longer antenna leads and optimum receiver placement and for sure one up in the canopy area, and one near the tail where it is in a very clean environment.

You should be able to look at the plane and NEVER see an angle where all three antenna packages are blocked.

If you take the time, you increase your odds of success dramatically.

I know of several who have flown twin receivers with no problems on 2.4

I have not really thought about the layout yet. For Batteries, I wil be using a duralite power box 40/16 an 2 2900mah duralite batteries.

I don't know of any of the guys on Team JR or others who work at Horizon -using two rx for the 2.4
additional satellite rx antenna ,yes but the so called redundancy and some of the God awful mish mash of electronic gimmickry I see stuffed into models -simply baffles me .
Having flown 42% stuff -I found that
A one properly setup rx and
B a simple good set of batteries - is all that is needed.
the wiring for big stuf is a real question tho - I see none of the Super Duper thingys as really offering a fix
the real problem?
The friggen connectors .
For way less than the price of the extra electronics - a set of well fitted Dean 3 pin connectors, throughout, servos n all would be a better fix - in my opinion. For the present - I simply splice (Y)in additional stock connectors giving two plugs for each critical wire path.
looks shi--y but works well.
The involved setups I sometimes see appear to be MORE fail prone -as opposed to being safer
Worse yet -some of these ringy dingy things are IMPOSSIBLE to trouble shoot.
Try as you might - ya can't beat a good simple setup
The advent of computers and jillions of plug n play devices -has created an atmosphere in which it is easy to believe just adding bits n piecs fixes the problem.

[niccolo98]

Yes, I completly agree with you. I think simple is better too. It is just i spent alot of money on this plane, and if i crash it do to me being an idiot, id feel better than if i lose control to me being a bigger idiot and not setting it up safe enough. I will try it with 2 and with 1 reciever. I like simple, but i like safe more.

too bad you cant use those for the rx connections--I like them a lot

[GooseF22]

Ive never used dual receivers. the only use I could see is if you cut the plane in half and wanted to simplify installation. seems to me, someone around there did that once?

I have done it twice now on 2.4 and helped on one other, that way you can power a 35% easily with 2 DX7s, who care what team JR does they dont pay what we do.
Using 2 cuts down on the need for Power boxes, matchboxes etc,simplifies wiring, put one on each side of the plane and if you use the 9000 for $25 or so you can get a satellite and put it up forward so the motor will never block the signal, D Snyder at Horizon suggests one at 45o
Youre talking about $99 to $169 extra and each sides power use is about what a 50cc uses, about 300-600ma per flight it would seem

[sweetpea]

Contact Jeff Szueber......he is running 2rx's with one satelillte per RX (instead of 2).

And he is Team JR/Spektrum

[mmcconville]

I recommend using one AR9000 with 2 satellites and 2 batteries (I use 2x 4500 Lipos) into the rx on a 35% and 40% model. I have never used a power box and have never felt the need for one. I agree with Dick H, simplicity is usually best.
If I felt 2 x rx were better, I would certailly use that set-up, but i dont.

man this is way too much work. i think ill stay with 72 mhz

[Panzlflyer]

How do you jam all those servos into 9 slots? Without using matchboxes?
2 power(at least) 2 elevator, 4 ailerons, 1 throttle, 1 choke and 2 rudder
Curious not sarcastic.
