Title: Problem with UBEC
Post by: SKY KALAI on May 16, 2020, 04:52:12 PM

Hi Guy's...
As I said in previous video,I just want to make UBEC for my Plane. I know It's not a BEC, it just Voltage Regulator. I tried it, but I have a small problem in it. That is when I connected a Capacitor ( 47 micro Farad ) in Transistor (LM7805) , the voltage out is 10v ( input voltage is 12v{3S} ). Only Transistor is connected with Battery, it gives 5.1-5.2v. So my questions below,
Q1. Does capacitor increase the voltage?
Q2. Does it perfect for Receiver?
Q3. Does it cause any problem?
Q4. What if i connect a 2 Transistor in parallel?.( I think the voltage is same, amps is Increase.. any other Else)
here the pic I made it.

Please tell me about your Suggestions :hatsoff: :hatsoff: :hatsoff: :hatsoff:

i would suggest two things
1) get brand new ESC preferably Emax or hobbywing skywalker esc ! that will solve all your problems
2) just make one post and update over there rather than having multiple post for the same issue!
