A while ago I purchased a hell cat and finally found some servos to start the assembly. Unfortuneatly I'm lost on the first step, it shows how to install the right aileron (therefore the left) but how do I hook up the other aileron connector to the reciever. I can attach pics of in structions if neccesary.

Thanks, Dave Trimmer

get a "Y" connector and plug it into the receiver and one into each servo

Or, if you have a computer radio, plug BOTH ailerons into the reciever (CH 1 & 6) and enjoy advanced features such as flaperons, ect!

Is the Hellcat your first plane?

I have a trainer and when I was on vacation I found it at a garage sale, and took it to a flying field one guy started it and gave me a lesson when we finished that flight another guy showed me the hell cat and it was still in the packedge and he was trying to sell it. I told him that I lived in Canada and shipping might be a problem. The guy that gave me a lesson on the trainer let me fly his hell cat (He bought the same model from the same guy). He and everyone else at the field thought that I was the best newbie that they have ever seen. So that was it I bought the hell cat. I only paid $130 for a $300 plane. And no I'm not going to use it as my trainer (that would be stupid).

I'm a control freak. I do what Mike described, channel 1&6, can control them independently (trim, subtrim, EPA's, differential, etc)

or you can keep it simple and use a "Y" harness.

Channels 1 & 6 may not be the same on every manufacturer's radio. The channels may be marked "Aileron" and "Flaps". So you plug one servo into aileron and one into flaps. Your radios manual will explain this.

Channel 1 and 6 may not be the same on all radios, AND he may not have a computer radio capable of that type of mixing. It sounds like he's thinking about the Hellcat for his second plane, so let's keep it simple. KISS!

Connect the aileron servos to the RX with a "Y" harness. The serovs, arms, and linkage should be mirror images of each other. That is, the servo arms should both be to the outside or to the inside. Not on the same side of the servos, but opposite. This will give the opposite aileron movement you need.

hwo makes this hell cat man? Is it a fully scale wing? I saw one the other day that had a wing with an airfoil about like my fourstars. It was scale looking, but taking to the guy it handles nothing like a scale bird. Its got the taper, but is a nice semi symetrical airfoil.

I looked at this like it was not my job to decide how Dave should set-up his ailerons. This is a decision only he should (or will) make. The two ways to go about it have been alluded to here and the directive to use his radio's owner's manual should help him make the correct decision.

I say if he has a computer radio, i would recommend setting it up on dual channels. For the simple reason of redundancy.

I had a servo die (on the ground, not in the air thankfully) and it was on a y-cable..i think it was either shorting out, or causing some mean interference, cause both servos would not move (took me forever to figure out what was wrong...thought it was the rx cause i didnt figure on 2 servos dying at once)

When i disconnected the bad one, the other worked fine...and none of the other servos were getting a problem from it.

SO now i always use duals...not that it will happen again, servo failure seems to be rare, and my case seems to have been even more rare...but why risk it if you already have the radio for it?

I would go ahead and setup your flapperons too. Dont use them now, just set them up while you have all your tools out and are already checking throws anyways

You would be amazed what flaperons do on some planes, on my nexstar (even with the tiny ailrerons) it seems to being the landing speed down to about 10ish mph...where its normally around 15 or a little more...its crazy how slow i can land it now

If the airplane uses barn door ailerons I would strongly recommend not using the flapperon option! Deployed flapperons with barn door ailerons sets-up wash-in in the wing's configuration which is a very bad condition and will lead to tip stalls! Since flaps are used at the time of landing approachs, this configuaration is very likely to cause a low altitude-slow speed snap roll into the ground!

Hey, Thanks for all the advice and I think I will use the y harness, The air plane is sold at giantscaleplanes.com (lucky is the nose art). As for the shorting I will use the Short proof plug technique from the Dec /05 Issue of model air plane news under tips and tricks. I have another question though, the rudder doesn't have slots or hinges so would these be them


Thanks again, Dave Trimmer

lets hope not those don't look right you might want to use HD hinge points or see if you have a CA hinge sheet it usually is about 9" long and 2" wide. you have to cut your hinges out of it usually about 3/4X 1" then check for hinge slots through the covering your inst. book should detail this if not check the web site there alot of threads on RCU about hinging surfaces

What you are holding is large diameter heat shrink tubing. I don't know what they plan on you using that on. Perhaps building up pushrod ends.

Is this the plane?

Yes thats the plane, It for some reason doesn't come with hinges and there is only one slot in the rudder, Is this right? also how tight do the linkeges have to be because the linkeges keep sliding.

Thanks, Dave Trimmer

Rudder doesn't sound right. Wonder what the assy manual says. Can you contact manufacturer/distributor or rep?

What linkages and where? What kind of slippage.

Any chance of a close-up photo of rudder and linkages.

If they sent CA hinges, they may look like a strip of stiff cloth that you are meant to cut to size.

At the point where the linkage is slipping does the connector look anything like these?

Yes those look similar, The link from the servo to the aileron slides in and out as the servo moves, the aileron itself with the horn is fine, and there were no hinges in the pack and only one slot for a hinge (see pic below). Unfortunatly the instruction are horrible. I will also try to find out if I can call someone.

Naggingly, Dave Trimmer

I'm thinking you mean these are on the aileron servo output arms. Sometimes the screws bind a little on a burr. Remove servo arm and wire from fitting. Then see if you can run the screw in until the head seats on the fitting or bottoms out in hole. If not, fix threads or replace fitting. If fitting screw can be tightened down fully but still slips on the wire you could file down the top of the fitting slightly to allow more engagement or replace. The wire may just be too small for this fitting also.

One hinge is not going to be enough.
