Title: Li Po Battery for an Oriental Arf
Post by: petermick on April 25, 2014, 09:58:33 AM

I am near the completion of my first electric powered plane.  The plane is a Brodak Oriental Arf.  It's finished weight hopefully will be no more than 45 oz. It will be powered by an E-Flight 15 using a Castle Lite 50 ESC and a Hubin FM 9 Timer.  I want to use a 2400 to 2700 4S 30C battery.  When I look at the List Your Setup string I can't find any consensus as to what brand of battery to use.  I am looking for recommendations.

Thanks

I've had good luck with GenAce batteries from Hobby Partz. You can get a couple for what a top of the line battery will cost.

Others will have their opinions.  😂

I have a couple of the Zippy compacts similar to the link Crist just posted, and they seem pretty good so far.  :)

I think the "consensus" is that most anything will do.  Having said that, the absolute top flyers prefer one or two of the absolute top brands (Thunderpower?  I dunno -- I fly 'lectric RC, but slime CL).

I'm thinking that the Hyperion batteries represent a good quality mid-priced LiPo.
Less money than a Thunder Power, but more than the HK batteries. Very likely better QC and return policies as well.

I'll probably get one each of a few brands and see if I can tell the difference for my first go around in ECL, which will also be with an Oriental. ;)

Chris

I have two Hyperion 4S 2500's coming, and already have two of the 4S Thunder Power Pro lite 2700's here....

My question is-

On ARF's like the Oriental, how many people have notched out the wing leading edge and cut a hole in the former ahead of the wing in the fuse, in an effort to get the CG right without tail weight added?
I suppose it may come down to the motor used, and how heavy it is?

I also suppose that I can mock up the assembly and see where the CG ends up before I bust out my trusty Dremel Rotory Tool.

Should I be concerned about weakening the wing by cutting the LE on this ARF?

Thanks for any advice, especially that of personal experience.

Regards,
Chris Behm

I have that same system on a 576 sq in plane and I use hyperion 4s 2500 mah and get flights of 5:45 min. with an 11-6.
