Aeolus E50SV electric motor KV rating

[AllanHat]

I've the E50SV that uses the seperate main and tail drive gears, not the revised version available in new releases. I'm wanting to purchase a Scorpion motor for it to replace the no-name motor that came with the heli.

The dealer I bought the heli from cant confirm the electric motor KV rating, can anyone advise what KV motor I need to purchase please for a 12S setup?

Also, anyone who has fitted a Scorpion to their Aeolus 50 I would be very interested to hear their thoughts, thanks.

Hello Allan,

A buddy and I have each an Aeolus E50 cf-version (gf -version has a tail-belt).

Our setup is a little bit different:

- buddy runs: Scorpion HK4035-530 (530 kV) with YGE 120 HV esc

- my setup: Scorion HK4025-550 (550 kV) with CC Ice HV2 80A

We both converted the basic cf-kit with the stock fbl-head and weboth run 2x Turnigy 6s Nano-tech 3300mAh LiPos as a 12s package. He's on the 30C version and I'm running the higher C-rate version available. Can't comment on this yet, as there's a lack of on-hand experience to make some judgement.We both run separate BEC's for our Rx, I think he uses a Yeti-BEC (?) and myself using a Turnigy 8/15A UBEC (very reliable for little money).

Pinion is the stock one, just ordered the same teeth pinion with the corresponding motor shaft size - as far as I remember this was the 6mm ID-pinion instead of 5mm for my motor ? Scorpion still sells some 600' class engines with ID 5mm !

My buddies E50 and his combo flies really nice - low noise level and E50 seems to have lots of power ..

Best Regards,
Oliver

P.S: I hope the CC Ice HV2 80A holds w/o vaporizing, anyway, if in doubt, you can't go wrong with the YGE 100 or 120 HV w/o ruining your bank account ..

Thanks Oliver, 4035 530kv it shall be then. I'll provide an update once I've installed and given it a run. I'll be using a Kontronik 120HV with a 12S setup which is what the heli uses now with the no name donk.

UPDATE..

Just picked up a HKIII 4035 530kv, for about US 180 brand new... I will post an update once i have installed it and taken the big ol' brid for a run.


Thanks Allan
