Is it necessary to use a BEC,for rc planes?can anyone suggest
BEC-Battery Eliminator Circuit
It is used to step down a high volatge(eg.3s,4s..etc.) to a low operating voltage (4.8v to 6.0V).
If it is a electric plane and the ESC has inbuilt BEC then not necessary for a separate BEC unless the servos draw more current.
If it is a glow plane with a high voltage LiPo or NiMh (6V & above) then BEC is required to power the Rx and servos.
If you are Not using a bec then you can power up the receiver through a receiver battery pack...
Most esc comes with built in Bec
Receiver packs are mostly used in the case of Nitro/glow engined planes, or for bigger models as santhosh said..
:)
Does the ESC available from rc bazaar have inbuilt BEC?
See the specs There will be clearly written that it has a bec or not... :thumbsup: :thumbsup:
Generally Electronic Speed Controllers used for BL motors, comes with BEC.
currently only 50A and 80A ESCs are available at RCBazaar.
