Volantex .... was originally the old LANYU label ... 

9x5 prop for 3D on a model 1100gr ?? 

Just for interest - the Hummer which has similar motor but lighter - for 3D work is at least a 10" prop ... best on a 11x5.5E.

I am not surprised that Hover is not so easy - 9x5 prop is not going to be holding her up well. 3D being mostly post stall stuff needs thrust and IMHO 9x5 just will not give enough.

On the point of CoG ... even Wargo does not recc'd pushing CoG back for 3D .. its all down to prop thrust and control surface size / movement ..

Good point.. the plane is VERY efficient with the stock prop.. It tends to fly "forever" on a 1800mah 3S.. 
So yes.. I think the setup can take a bigger prop which will at the very least make Controlling the hover easier.. I now have use large strokes with the throttle to control it.. 

Ohw well.. with the stock prop it is a easy going beginner / trainer.. 
allso: the stock prop isn't really a 3D prop.. you might have noticed 😋

Contrary to some - I hate Slow Fly props and cannot understand why someone wanting a crisp throttle response ever uses them When I've tried recc'd SF - everytime I punch out from a trick - you hear that prop WOMP WOMP as it flexes and tries to bite. 

My preferred 3D props are the 'bone' props from Hobby King ... usually title APC Style or Aerostar. Strong, light, no flex and boy do they bite when you hit that throttle.

you Need to try some recent multirotor propellors eventhough most of the development there is in 5" ones.. 
multirotor hover or fly not-all-that-fast like 3D planes do.. 
The biggest engineered prop like that I see is a Gemfan Flash 7x4.2 regretably.. no use for This airplane.. 

Before those came along I used Master Airscrews most times..

I do fly Multi-Rotors including DJI .... used to do Reviews for a few brands ... 

The best props for 3D are of course stiff Carbon Fibre or wood ..... but an excellent compromise are the GFN props - Glass Filled Nylon - which today are usually termed Composite or Resin Prop's. Master Airscrew ... APC .... Aerostar Bone .... and most brands of E prop are GFN. Not of course Slow Fly - which are a poor cousin.

On that Saber ... I would be inclined to throw a 10x6 or 11x5 on it ... see what happens.

I've got a couple of 12x6's 😃  hmm.. don't worry.. I'll go easy on it.. just to see how much better the control is..
I'll probably end up with a lot of torque roll 😃

12x6 is a bit OTT I think .... I have used 12x6 on similar setup - but yes - you have to watch torque roll. Once flying though its not so bad. Its if you hand launch or drag of ground too quick.

The 11x5.5 is THE prop in my view.

My Hummers and EPP MXS both use these and it performs very nicely ... about 60% throttle ... basically I can feel her pulling out of hand and I know she's not going to fall... but not ballistic throttle !!

Just put the data into a flight calculator and the 9x5 prop only just hits 1:1 Power to Weight .... no wonder it is hard to hover.

10x5 gives about 1.2 : 1 .... still will be a handful to hover.... but usable.

11x5.5 gives 1.4 : 1 ..... now we are in the realms of hovering ! But amp draw is of course higher ... 

I use 30 and 40A ESC's on similar setup ... the 30A of course is working quite hard...

😃  yeah.. some experimenting with props is in my planning 🙂  

30 / 40A .. yes.. for planes in this size I generally swap out the stock ESC with a HobbyWing 40A.. Eventhough i haven't really had problems with the Volantex ones.. 
I just know the HobbyWing's will work.. that does make flying more comfortable

Volantex is the old Lanyu and the ESC's I saw were re-branded Mystery's or similar make. I never had any trouble with them. But they were what I class as minimum amp rating for the job.

I have to say I like the look of the model ... in fact I've been scrolling through Banggood pages a lot recently. They seem to be competing with Hobby King ... which IMHO has taken a dive for the worse recently.

No idea what is going on at Hobby King - but their line-up now is disappointing to say the least. A lot of the old fav's have gone. Victim most likely of their policy of picking up 'end of line' products for so much.
