Yeah the limitations appear to be the trim functioning on both ailerons.

Maybe the easiest route to go is using matchboxes in the wings. Not maybe, it would be easier to use matchboxes for the wings.

This wasn't a problem for the 12x but that's not much help for a guy with a 9303.

So as you read through this you will see lots of thoughts.

I have a 10x and here are my thoughts with the 9303.

First your Ailerons:

- you can use the radio to run all servos without matchboxes or eq's (if you only run 9 total servos). or you can put the rudder on a matchbox and aileron servos on the radio
-you can use a jr matchbox or SF EQ.....you can do this 1 of 2 ways. You can put all 4 one box but then you cannot do differential which is why most folks use 1 per side of the plane.
-You are using HItecs, so you could use the programmer also and that will help

*my thoughts on setup....in this case that you only have 9 channels and will most likely be running 2 rudder servos, 4 aileron servos and 2 elevator servos (total) and 1 throttle. If you do the matchbox route I would prefer the SF EQ's and in this case I would just get the SF EQ6 with the Optic Kill built in. Best bang for you bucks. This is what I run in my planes.

Batteries:

Yes to everything above. You can run any of the batteries you want, depending on what your servo can handle

-A123's you must watch mah you use. Typically 3-5 flights and you recharge. You cannot test the voltage though like you may be familiar with to determine failure. They hold voltage until they die suddenly.

-Lipos...these are fine but voltage is typically higher so if your WARRANTY doesn't say it can handle HV, don't run them. If HITEC is saying you can, get it writing first! Also don't charge these batts in the plane. Too many fires associated with LIPOs to risk that.

-LION...Nothing wrong with these but you will typically need a regulator. You can voltage test them. Overall though they are not for HV servos (which is not what you stated you have)

*My choice is still LIONs. Easy to charge, last a few years, don't typically blow up and I can check them. Everyone has their preference though, find your own! Here is another reason I like the EQ6, it comes with an adjustable regulator.


Now for battery manufacturers-----There are not many bad ones out there anymore. Stay with some name brands and you will be fine. I have used TBM, Fromeco, TEnergy, Zippy and I'm now making my own packs.

Doing some research on this myself so I have to ask why Ions are not for HV servos. Honest question, I've not heard this.


Also 100% agree with everything you said here, but I would still Sh!$can the old 9303 and upgrade the radio. Power safe RX and pick your servos. No match boxes and all that junk.

personally, I think if you are running HV servos you need voltages that remain constant throughout. LIONS voltage drops off significant as you drain the battery. This is if you want realize the advantage for HV every flight for the entire duration

Personal preference of course. I don't see the need to get rid of a decent radio though. I still use my 10x and it forces me to use matchboxes....but the radio is solid and easy to use.

Don't lipos...have similar discharge to lions? Can you really feel the difference between 8.4 volts and 7.4 volts?

I see where sweetpea is coming from. Fromeco recommends charging ions when they load test at 7.0 with a 1 amp load. Flying really hard is way more than 1amp so I can definitely see them feeling somewhat different from fresh to charge time.

Makes sense to me.

I wish I flew well enough to tell the difference. :-)

You and me both Phil.

PHuck and Neal maybe, most of us though wouldn't know unless we were told. But if it makes you feel better it will make you fly better

Certainly not me....and I remember a post a while back that kyle Dahl couldn't either.

I know when I used to race RC cars I couldn't tell a difference in low IR packs. After a couple years of racing/practice though I could tell a fresh pack vs an old pack in both steering and throttle.

I could see that relating to control of the surfaces in an airplane, though I have yet to feel that. I would imagine in the smaller size planes its more clear than in something like a 40% where the surfaces are larger and slower.

Probably why heli guys can feel the speed differences in servos so much.

Makes sense...

Ok so here is the deal. The plane only has one servo in each wing. I bought the airplane from Tom, the owner of Wild hare. He sold me one of his personal planes but he only had it iset up with one servo on each wing. I believe they are 7955's. So life is good there. Now, if I am planning on doing 3D, should I put the extra two servos in the wing?

Don't bother, just fly it. Unless you get blowback leave it be

That simplifies everything. All you need is the AR9110, an IBEC and 2 batteries of your choice. Simple, reliable setup

Our work here is done.
