Amp draw from Futaba
Going to have 3 S3004, 4 S3010, and one Hitec retract servo along with a gear sequencer. I want to get a BEC to use with my 3300mah 3S Lipo to run it and the gas ignition, so I need to know what kind of amp draw I can expect off this radio setup. It is going into a warbird, so no fancy stunts, other than high speed passes.

You should be able to get around ten flights with that setup. This depends on the size of the air plane though.

I dont have a BEC yet. I need to get an idea what the amp draw could be so I can order the correct one. Locally I can pick up a 3 AMP bec, but I dont think that will be enough.

I considered a LiFe pack for this, but would still need a 4 cell pack for the ignition. Since I have 4 3300mah 25C 3S packs for my EP planes, I could always use one for this plane too. I have 3 Gen Ace packs and an Eflite pack with a lower C rating. I was thinking of using that one since I rarely use it.
So, will the 10Amp be sufficient? The draw on the Ignition is under 600 Ma at full throttle.

Well, after reading up on the DLE20 ignition, I discovered it works best @ 4.8v, so foregoing the BEC, going to get two separate packs instead, a 4.8v and LiFe for the RX. Probably a 1000mah 4 cell and 1800 mah for the RX, or whatever I find close to those ratings.
I doubt there is a Bec with dual output voltage that would be worth getting for this, just to keep from buying the packs, probably will be less expensive with just the packs.

There are also those BECs designed to plug into the receiver and provide power to the gas ignition from the receiver batteries. I think Troy Built sells them and I have only seen favorable comments on them. I am considering this for my current warbird build and using LiFe batteries for the receiver.

Hi Ed,
That's called an IBEC, it also provides an opto coupled ignition kill function and the new version of the Wike IBEC from Troy Built Models has an adjustable output for the ignition[8D]

RE: Amp draw from Futaba
Picked up a pair of packs, 4 cell 2000 mah nimh and 1800 mah 5 Cell nimh, This should be a good start for now, can always add a bec and life later, but for now I can get the radio working and balance out the plane.
