Default Please help a beginner

Please help a beginner

Greetings

I am new to the flying field and want to prove a flying concept, which needs at least two identical motors. I have two identical edf brushless motots, one brushless esc without BEC, Tx/Rx and a lipo battery. As a beginner, I have already learnt how to set up one motor and run it at the full speed. Please see the picture. What I need to know from experts is that what is a best choice to set up my both identical edf motors to run at full speed at the same speed.

My transmitter is mode 2 by default. When I connect esc to channel 3, the control on the upper left corner of the transmitter becomes a throttle. But when I try channel 1 or 2 or 4 the motor goes to full speed after I put the transmitter on and doesn’t respond to any controls. It stops only after I put the transmitter off. When I try channel 5 and 6 the motor goes qiet and doesn’t respond to any controls. As a beginner, I was thinking I would get two throttles on the same transmitter to run both motors but now I found out it is not possible.

Any advice from experts about how to set up two identical motors will be appreciated a lot.

Regards

Hi And Welcome to Wattflyers,

1. First things first Always turn on the transmitter First then hook up the lipo to the power system, motor, esc, receiver servos, Always disconnect the power system before turning off the Transmitter, The transmitter is the first to go on, and the last to be turned off, ALWAYS.
2. use a UBEC if your ESC does not have a BEC or if it does, Remove the red wire from the plug that plugs into the Receiver on all ESC or they will fight each other and burn up when using a UBEC.
3. use 2 ESC for your EDFs, hook the esc receiver plug into a y connector so both esc are being controller by the transmitter and receiver.
4. reset your ESC throttle end points.
5. just use one Lipo to power both esc, make sure its 25% bigger in amp rating than whats needed for 2 edf , use a wattmeter, its a Must have to protect your investment, use a ESC thats 20 to 25% bigger than what the EDF motor needs, it will stay cooler and last longer, Hope that helps, Chellie

Many thanks dear CHELLIE.

Now I know everything I need and ready to order the rest of the components to test my flying concept.

You are a lady and a tutor.

Many thanks again

As Chellie says two brushless motors need two ESCs. Both ESCs can be connected to the same channel on the receiver using a Y-lead.

It's not clear what you're using to power your receiver. If the ESCs do not have a BEC then you need a separate battery or UBEC.

Dear Steve,

At the moment I am using a separate power supply for the receiver. But when I go for the full assembley of my concept, I am going to use UBEC. It is a lot lighter.

Many thnks.

Kind regards

Chellie gives the best advice here. Always ! But I have the same question as asked by Angler and Bronco? If you're new to RC, what are you doing with twin edf's ? Sounds like a handful for a beginner IMO.

Good Luck !

Default Regarding my new flying concept

Greetings.

Thanks for those asked about my new flying concept.

I am an inventor, well that is what I call myself, and I am trying to reinvent the wheel. I am trying to build a prototype of a version of my patent-pending 'wingless flying car.'

Very very interesting Concept i Like it, Reminds me a little of the gravity plane that uses Helium and gravity for propulsion.

It is always helpful for all participants in the forums to state their location, at least the country in which they reside as that can determine how an answer is made. Different countries have different rules and regulations and these forums cover citizens of all countries who wish to participate in them.

Dear Lady CHELLIE,

This gravity plane is a sci fi fiction. It supposed to leave the ground on floating principle like baloons filled with lighter than air gases like helium. Later when reaches maximum hights acts like perpetual machines. It is not practical and it doesn't work.

Kind Regards
