Advice needed on motor/ ESC combo

[900dukess]

Hi all, I know this question gets asked all the time but I am helping my neighbour upgrade his SC
He will be using a dx6i, I am after advice on which turnigy brushless motor to get. I have a parkzone 480 but was looking for something with similar power, but less power than a 35-36. Also what Esc and prop set up would help. Looking at getting everything from hobbyking. Also what servo can u guys recommend, thanks in advance. Oh yer he is also looking at using his existing 1300 mah zippy batteries 20c/25c I think, so keep this in mind regarding prop size, like to get 10 min flight time

Here is my setup all from HeadsupRc.com

It rocks! fast and fun!
A good set-up for the HZ Super Cub is:

450 Sport (includes 4mm prop adapter)
32A Power Up ESC (I used a spare E-flite 30A I had)
GWS 1060 prop
(2) TP SG90 Servo (typical 9g micro servo)
Supercub motor mount they sell
I use 3S lipos from 1550-2200mah 20-25C

Shipping is wicked cheap as well from headsuprc. I think like 2.00 and I had everything in a couple of days.

Then I sold all my stock electronics for 60.00, so I pretty much broke even.

Here is my actual cost break down

450 Sport (includes 4mm prop adapter) = 20.00
32A Power Up ESC (I used a spare E-flite 30A I had) = 22.00
GWS 1060 prop = 3.25 for (2) (already had, that is the prop I used on stock cub with lipo's)
(2) TP SG90 Servo (typical 9g micro servo) = 4.00 apiece
Supercub motor mount they sell = 20.00
Total = $73.25 + 2.00 shipping
Had everything within 5 days
I did have to buy a Rx, Ar600 = 50.00

I use 3S lipos from 1550-2200mah 20-25C (Already had)
I already had a DX7
Then I sold all my stock electronics for 60.00 so it worked out well for me.

So if you have a radio already and batteries you can do it for not much cost at all. (turn around and sell your stock electronics, and that will help)
plane is much faster, and funner to fly, handles much better as well with better servos. All around much more enjoyable to me.

Hey Gaga (sorry couldn't resist),

Are you running this setup with 4 servos (ailerons) or stock (rudder/elevator)?

I am asking because I am looking at this setup for my cub and wondered about the draw of the motor and 4 servos on a 32A ESC?

Thanks,
Rod

Hey guys, if you are looking for some fantastic information on ESC,prop, amp draw and so on, then go to HURC's web site. You cant beat it. Jeff has compiled so much data on different combinations and he tells you straight out what props,esc's,motors and with what kind of battery he did the test with. It's all pretty simple. Just pick a motor and click on it. On the motor page he gives you all the different props,the amperage draw for each prop & the thrust. He also has pages of information that is very easy to understand. I know, i must sound like a salesman but the truth is I order a hell of a lot of stuff from Hobby King. Thats where I get all my Lipos!! But when it comes down to the end price you pay for a 35-30 or 35-36, or just about any brushless motor, its only 2 or 3 dollars more at HURC and sometimes its actually cheaper. I'll pay a couple of bucks extra for the service that they give and also getting everything you order in 3 to 5 days!!!!
900, a great starting point would be to know the exact weight of your cub. You can get a cheap digital hand held scale for about $10 bucks on ebay. After you know the weight then go to HURC's site and pick a motor/esc,prop combo thats gonna give you the performance you want. If your cub weighs 28 oz's and you want unlimited vertical then its obvious you need a motor and prop combo that will give you a bunch more than 28oz's. I recomend having the ability to test(weigh,measure thrust,wattmeter) and know for sure what your system is doing. Take a look at this:

www.headsuprc.com/servlet/the-1427/3530-dsh-11-Outrunner-Brushless-Electric/Detail

Say you were to put this motor in a cub. Run it with a GWS 9050 prop you would get 36oz's of thrust and pull only 18 amps.
Run it with a GWS 9075 prop you get less thrust (32oz's) and run the risk of burning up your motor because your pulling the max rated amps(25) for that motor. IMHO this is information that is critical and not so difficult to figure out yourself. Jeff recommends a 32amp or a 40 amp ESC. A 32 amp ESC is just borderline ok. Why? Some of us like Flydiver, myself and others have had some in depth talks about this subject so if you want to really understand it then go back and read our old posts. But the short explanation is you only want to use 80% of whatever the label says!!! So that 32amp ESC should be able to saftley run at 26.6amps. As you see your real close to the max of a 35-30 motor depending on how you prop it. A 40Amp ESC would be my personal choice because it gives you a lot of headroom if you decide to upgrade to a larger motor later.

This is all a lot of info but the point I'm trying to make is IMHO its much better to know why your choosing a setup and once youve got it installed, know how to test it to make sure its doing what you expect it to.

Thanks fly,

I am fairly new to these things and have been trolling the boards and reading up on info.

You are one of many who recommend HURC's stuff--I will definitely give them a shot.

My local LHS was friendly and helpful, but missed a few key points when I was talking about upgrading my cub. For instance, that I have the lp, which is FM and will require a new esc and will require 2 more servos in addition to the two they sold me for the ailerons due to the 5 wire vs. 3 wire. Again something I figured our from reading all of good info here.

Thanks again.
