Brushless Twin setup
Hi all - have had a lot of fun flying electric models having spent years with the petrol stuff. My question is does anyone have a diagram or explanation on how to connect two motors on a twin with regard to the engines, ESC, receiver etc?
It is simple enough with a single engine (fly an Extra300 atm) but am new to it all with much else.
Any help greatly appreciated - thanks guys and blue skies! -Mark.

G-Day
i am prety sure you need 2 esc's i have herd of people using one esc on 2 motors but god knows how
you might be able to use a Y lead to conect the 2 escs up to the RX.it would be best to use some good lipos as well.
good luck with that mate
happy flying

I used a Y Harness to connect the esc's to the receiver on my E Flight P-38. Then ran both esc's power wires to one deans connector to the battery .Pretty straight foward and it works. Mike

Hey I do helicopters too. I've been flying fixed wings forever got the helicopter bug about a year ago. Its all good. I just started playing with electric planes since I have amassed a number of Lipos. Best of both worlds. Mike

RE: Brushless Twin setup
I currently have two twins. A GWS P-38 and a Hobico TwinStar.
In the P-38 the Castle Creations (CC) Thunderbird 18 Amp ESC's connect to a "Y" and plug into channel 3. These ESC's are good to parallel the BEC's, some others are not. The ESC's are in the nacelles and connect to a hand made 14 AWG "Y" to a 3S1P 2100 (6 min) or 3200 (11 min) LiPo.
The TwinStar is similar, CC HV45's are in the nacelles with the 4120 motors. A 12 AWG "Y" connects the ESC's the the 6S2P 4200mAh Lipo in the center of the plane. I use an LM2576-5.0 as a BEC, goto DigiKey.com for a datasheet.
I both the props counter rotate to make turning right and trimming easier.
It is important to test any new setup. I strap the plane down, run the motor(s) at 1/2 to 3/4 power while moving all the controls for 3 to 5 minutes. As I do this I keep checking the watts and amps, the temperature of the motors, ESC's, batteries and other parts. If everything is working correctly, no part should get hot. Anytime an ESC gets more than the slightest bit warm something is wrong, wrong timing, bad connection, motor and ESC don't like each other...
