The 2.4ghz full range style Rx's today will handle 20amp surge, IBEC's dont see anything near this current, but one must take care to bridge the IBEC for correct ignition input voltage

I am running an ibex on a 40% Aeroworks Freestyle 260 , DLE 60 twin and 2 NiMH 2700 mili amps( No BS) Batts.
The batts are tethered together via a batt share system , for both redundancy and assistance in sustaining voltage/ current in peak demand periods. The combined Batt system ( with IBEC) gives an increase in total battery capacity as well.

The IBEC is connected into the Rx via the gear port and can be ditched on and off from the Tx.

The is the sixth or seventh plane I have used an Tech Aero Ibec and NEVER had any kind of problem.

I do start checking remaining battery capacity after the 6th flight of the day , as a precaution.

Considering replacing the batts with A123's again from NoBS , but have not decided yet.

Other then the servos I have this exact same setup on my 35% yak. 12 channel JR powersafe powered with 2 Life batts (2100 mah) powering the whole system. the Tech Aero IBEC plugs directly into an unused channel on the RX . As far as pulling too much current please note that the Powersafe Rx's are rated at 35 amps continuous and 50 amps surge so don't worry about that. Just make sure you have enough capacity in your main packs. With 2 2100 Mah packs I get about 45 minutes to an hour total flight time before consuming a little over half the capacity. You will love the simplicity of the TA IBEC. I have them on all my planes

edit: oops got your post confused with another and thought you were asking about powersafe RX

Thanks for the info, but I think you mean its a 30%. I don't think a 60cc would get off the ground on a 40%?

Read on another forum that the 6014 is rated for 8A continuous / 10A peak. I think I am already pushing this with just the servos and worry the ibec will be too much.

Anybody have any actual amp draw numbers from an ignition? This one is a DA85.

FYI for anybody going down the same path as me....DA said thier single cylinder ignition only draws about 0.5A at WOT. I think I will be fine.

There was nothing to worry about in the first place -

Stay off RCG.

.

You aren't pushing that receiver. You aren't even making that bus trace warm. It'll handle more like 20 amps continuous and 40 burst. 8 amps continuous? A 14 channel receiver? Come on! If Bax or somebody at Futaba publishes that data then I might believe it. Even mine is a guess, but a lot better guess than 8 amps continuous on a 14 ch receiver. If the servo connectors are rated at 3 amps continuous and you have say, 15 ports on the receiver, that's 45 amps right there.

You are correct. Thank you.

It is an AW 60 cc Freestyle Extra 260.

Can anyone post how does varying the input voltage to the IBEC effect the operation of the engine or it's performance?
There is a thought that it has no effect and will merely draw more current.

Anybody have any insight here?

Less voltage equals more amps for the same spark. More voltage equals less amps for the same spark. So, if you lower the voltage on the ibec your ignition will pull more amps (draw more current) than if you use the higher voltage setting.

I beg to differ. Higher voltage means more power dissipated, which means the IBEC and ignition will run hotter. Remember Ohm's Law - voltage is directly proportional to current. So as voltage increases, so does current. Therefore increasing the voltage will have no effect on the ignition other than making it run hotter. You will not get a significantly hotter spark.

I suppose it is different for other ignitions but the DA 35 manual states the higher the voltage the lower the current draw. This ignition has a constant power converter to charge a high voltage capacitor.

Haven't read up on the rcexl ignitions even though I have a few of them on other engines.
