I'm working on an electric ARF and was planning on using a Hacker B50-13S +6.7:1 and a ThunderPower 4S4P. I also have an UltraStick that I was thinking about converting to electric. I did a weight check and the UltraStick with the Hacker would come out to 5lbs 11oz.

I ran across the AXI 2820/10 and got to thinking. It would only need a 3S3P so the difference in price would be over two hundred and the difference in weight would be close to 15.2oz.

But how would it fly?

Does anyone have any experience with the AXI 2820/10 on a 5+lb plane? What battery and prop did you use? Can you compare it against a Hacker B50-13S +6.7:1 with a 4S4P?

Thanks for your insights.

i have a AXI 2820/10 on a magic. AUW is 4.75 lb. Its ok but vertical is limited and no hovering. I dont have anyexperience with hacker, by the way i use HECELLs which weigh 12 oz and its a 10 cell.
just my $.02

I looked up the HECELL's. They are 1100mAH and only cost $33.99. Nice.

What prop do you use?

What kind of flight time do you get?

How did it balance? Any added weight?

The 3S3P I was referring to is 6000mAh, weighs 12.2oz, and costs $200. I realize that the flight time would be significantly longer, but I'm not sure one should fly more that 8-10 minutes at a time anyway (to avoid overheating). The HECELL's sound like a good (and economical) alternative. I can see how you could easily have two HECELL packs and change/charge while the motor was cooling (and have money left over for the next project).

The Magic is a great plane and looks to be a good choice for an electric conversion.

Thanks for the info. That's helpful information.

i used like a 12x4, 6 minute full throttle flying time. I had to stick the motor way out there to avoid adding any weight.
I changed motors now, i have a jeti-phasor with a gear box, 15x8, 9 minutes full throttle and performance is about the same. Im planning to put the AXI in a Super miss and that should be plenty of power.

Hacker is very expensive but i think you should try an AXI 4120/18. it costs $40 more than a 2820/10 but has 511 watts with 16 cells. It even pulls less amps than the 2820/10. I saw a guy put this in a Model Tech P-51 Mustang and lemme tell u, it was great, and it was in 25 mph winds. But of course, its all up to u.
Good Luck!!

Good luck, really!

Sorry to say, there is no comparison between hacker B50 / Axi2820/10, they are just another day stories[:-]
