Newbie Aileron Setup Question

[mdg76]

Hi Y'all

I'm wondering if I can call on your collective experience with adding ailerons to the Super Cub. I've put a lot of thought and done much research on what I'm planning on doing and I'm hoping that you folks can tell me if I'm on the right track or not... So here goes..........

I'm starting with a stock (except the landing gear), red (NiMh powered) Hobbyzone Super Cub

I'm going to cut 12" by 1.75" ailerons starting just inboard of the curve of the wing tip. This should give me over 4" of space left for when I install single servo flaps.

My plan is to model my hinges after those on my Parkzone P-47, using hinge tape. My first question is do I have to do anything to the foam surface to prep it for the tape and do I have to put anything over the tape to make sure that it stays attached? I also have some small Du-Bro nylon hinges that I was thinking of putting under the hinge tape. Is this needed? What would you recommend for control horns and where on the aileron should they be mounted?

As for servos, I'm going back and forth between two servos from Hobbyking.com

or

If you could give me some advice, that would be great. Whichever I pick, that's what I'm going to use for all the control surfaces.


I'm going to use an OrangeRx Spektrum DSM2 reciever

I'm planning on keeping the stock brushed 480 motor and using a 20 amp brushed (Lipo compatible) speed control

Will a 20 amp ESC be enough or should I go with 30 amp?


And finally to power the setup I'm going to use a 1300mah 11.1v 3s Lipo

I've has good luck so far with Hobbyking's Lipos.

So any help you could give me would be greatly appreciated. Thanks in advance!

1) servos: Hextronic 9g - same as I've used for nearly a year now - Cheap and powerful!
2) Orange RX - Use one as well - No loss of signal and very good for the price!
3) ESC - Totally fine, but use a 30 amp, and get a seperate 5a Ubec - if you have 4 servos or more, you need it...honest!
4) get the 2200mah, and open the battery box using the methods in the tips'n'tricks section. Make sure you get the 20-30 C lipos, as they give a little more 'oomph!'
5) If you are going to stick with brushed, buy another motor now. Mine burned out in 6 months of hard, fast flying. It cost less than $10 to replace, so, get a spare while you can!.
Good luck!

Ok.. I'm a bit confused. Doesn't the ESC have a BEC built in? And if it does, why do I need a separate UBEC? And if I do put one in, where do I put it in the power setup?

Yes, the ESC does have a seperate Ubec built in, but it's only a 1 amp! As for why...I was using a towerpro 30 amp ESC with a 3 amp Ubec, used 4 servos and throttle in flight, and lost control ( details on this site). On investigation, the loss of control was due to the servos and throttle needing 4+ amps, causing a temporary 'shut down' ( Brown out) of the reciever. So I now only fly with a seperate Ubec, which, in the event of a motor shut down, will still provide power to the servos.
The Ubec plugs into your ESC, and is a clever piece of kit. In the event of low voltage, it will save your plane. Think of it as insurance, no-one wants it, but you really do need it, 'just in case'. Hope this answers your question.

PS: Please...in your profile, put where you are from, as you could have a member in your area! Upstate NY means little. do you mean jersey? NY is a big state!

Please forgive my ignorance. I've never put a power system together from scratch before. I'm looking at a UBEC. I see a JR type plug on one end and two bare leads on the other. So I assume that the JR plug will go into the throttle socket in the receiver, but where do I hook up the bare wires? The ESC looks like it has two wires for the battery lead, two wires to solder onto the motor and 3 wires which I'm guessing go to a male JR type connector to plug into the throttle socket in the receiver. AHHHHHRRGH!!!! I'm confused! Please help an ignorant Yankee!!
