Good Combo for E-Open B
Buy this $35 motor. The one on top the 36-50-1500 http://www3.towerhobbies.com/cgi-bin/wt ... LXLWZ5&P=7
this $35 ESC http://www.bphobbies.com/view.asp?id=A0 ... d=B1818513
and two of these $55 batteries or any good 2200mah 5s batteries and run them in parallel

And make sure that your airframe doesn`t weigh more than about 30oz without these items.

One detail is that I add a second set of input leads to the ESC. One set goes to each battery. This has worked well for me this year.
It`s a simple clean way to run the batteries in parallel. It also reduces the amount of amps going through the bullet connectors. If you run a "y" cord, the plug leading to the ESC will be dealing with about 50a. This way each side just carries 25a.
Here`s the whole layout.

I use clear tape for test flights. I use two layers of strapping tape for contest heats.
I like to have half as many batteries as heats that will be flown in a day. 3 sets for 6 heats ect.
I stay with a plane unless it gets damaged or isn`t flying well just like I would with IC power.
I switch batteries between heats and charge out of the plane.
It takes about 45min to recharge a battery after a heat. So if the contest is going to be run at a very fast pace, it might take an extra set. Usually a lunch break is enough to get everything topped off.
You do need enough charging ability to charge two sets of batteries at one time.

Another question, I have dealt with Tower Hobbies in the past and it was OK, I have purchased from BP too with no issues.
Have you or anyone else done business with United Hobbies? They appear to be an overseas company, so I am concerned with legitamate dealings and shipping costs. Mostly, have you had good service from them?
I have Dymond Model Sport hobby shop down town, and the actual owner runs the place. They are big into electrics, and very helpful, so I might try to find comparable equipment in their store.
I am on 6 days, 12.5 hours per day thru Jan. 5th or so. I won't be doing any building until after the new year most likely. Dymond is closed on Sundays as the owner goes out and flies with everyone.
I am cool with the online purchases, just curious about United Hobby.
If they are cool, I may just buy online and get it delivered..

I`ve had 14 orders from them with no issues. Some of their batteries in early 2007 had problems, but they seem to have corrected the problems. Shipping adds about 10% to the costs, but isn`t much more that we pay in sales tax when buying locally. Delivery takes about a week as long as the items are shown as in stock.
