Default TREX 700E powered by Hacker A50-14L & 10S 5800mah?

Hello everyone, really tempted to convert a trex 700 to electric and power it with my existing Hacker A50-14L and unused 10s (2 x 5S) 5800mah blue Turnigy packs, would really help making it affordable, could this combination work as a (first) power system?
Would it be sufficient for graceful intermediate 3D flying?
Could I then move to 12S with the same motor?
Apologies for all the questions

Thanks ever so much everyone, hope to be joining you in the trex 700 forum(s) soon

Where did all my replies go?

Was just wondering if this motor could be used with the 10s 5800mah packs and kontronic 55A 10S Jazz for a super low headspeed 700 (~1000rpm-1200rpm) now I have the 700N for 3D? Would be fun to fly around scale and smooth before getting a scorpion motor and 12S next spring

I think it would take more skill to 3D with such a low headspeed, be more of a challenge, looks like fun

Would the setup work? (even if you wouldn't enjoy flying it)


Thanks


Edit: Did you watch all the way through? Starts off boring but gets good after 1:40

That's a 540KV motor right? If so you should be able to use it. It would be a down on power compared to a Scorpion or Kontronik but it should work fine. I believe you could run that motor on 10S or 12S depending upon the pinion and head speed you want to read. I just put a Kontronik Pyro 700-45 in my 700 E conversion so I have a Scorpion 4035 560 laying around if you don't want to buy a new one let me know. It would provide quite a bit more power (4200w vs 3000w) but the hacker should work OK if you don't need a ton of power. Maybe someone here has actual experience with this motor in a 700?

i'm currently considering that Hacker motor to convert a gasser. I am mainly concerned with duration and also a lower than typical headspeed. ....720mm at 1650RPM or 800mm at 1450RPM.

Very nice flying! I like the more scale rotor speed and the blade sound at that RPM is great.
