Excuse me for posting in an old discussion thread, however, MotionRC has announced a new 70mm EDF Jet known as the VULCAN

https://www.motionrc.com/products/fr...GTeOEai.LUYCSB

Seems they are using the identical power system from back 2017.

Does anyone see this power system as a good quality? I am thinking about this model but, not sure if this model's EDF power system is any good with 4S.

Here's the MotionRC web site showing the EDF 70mm 4S power system:

It’s not that efficient, and it’s not horrible either.
The WeMo Evo fan is much better. See here:

IMHO, I don’t see how a 4S 4000 in that airplane would give good performance, but that’s just me.

I believe there is a typo, should be 2850kv instead of 2550kv, for this Freewing 4s fan: https://www.rc-castle.com/index.php?...roduct_id=9149

I agree it is not that efficient as I tested it on 70mm F-117 and Mig-15, on larger high C 4s battery it might do okay, making the Vulcan flyable but nothing exciting. 70mm EDF on 6s 3000-4000mah is the way as long as wingloading is not an issue.

For the 6s 3000-4000 lipo there are quite a few options from CNHL, RCBatteries, and Hobbyking

This is the same motor and fan they use the FW Rebel V2, right? It does okay in that plane... I'd want 6S, but it someone wants a slower flying, less powerful, somewhat lighter, Vulcan, it'd fly it.

Guys,

Thank you ALL for your replies! I have ordered the Freewing 4S EDF Power System as I will be placing some super light batteries 4S, 3800mAH in my Habu-2. This power system will be much better than what it has now, the weak E-Flite 5-Balde.

I am not a proficient EDF Jet flyer but, yes!

I got this E-Flite HABU-2 in pristine condition with a Castle Creations 100-AMP ESC.

4-Cells, 4,000mAH, 45C and no gusto.

I can't wait to receive my MotionRC order!
