Sharon 4200 motor & prop suggestions

Hi,
Could someone drop some motor names and prop sizes for the Sharon 4.2m electric

I like Hacker & Neu

I've seen MVVS motor 690 but its 700w max may not be sufficient

Sport flying no comps but I do like having enough juice

Have used both a 1506 6.7:1 & 1509 6.7:1 with aero cam folder 17x10 to 18x10.CC85 & cc125 with 4cell 3300mah 65C TP pack. ~800 to over 1800 watts. Uses ~ 250-400mah per climb as shown in pic.
Attached a few pics of ~1100-1300 watts on the 1506 6.7:1 17x10 cam folder showing climb rate and current draw on 4 cell pack. It goes vertical, but not super fast.
Your going to like the Sharon.

EDIT
Correction prop is 18x10.

Hi Kilwein,

Thanks for the info very handy

I read your Sharon build thread looks like fun all the way

Which 1506 Neu model did you use with the 17x10 prop ?

Here is some E-calc data for the Neu 1509/1.5D/6.7 with a RFM 16X10 prop. Using the older CC Phoenix 125 ESC.
This is the setup I fly with my Nan Alex XXL on 3S. I also ran the numbers for a 17X10 prop on 4S, but haven't tried this yet .

Sharon Motor

Hello Firehorse,

I have this glider on the top of my wish-list, will get it as soon as the finance allow...

Please let me share a little bit of my experience, successes and frustrations.

An underpowered glider is something really bad and dangerous, specially with a big glider like a Sharon.

I use to own a Big Ceres, little smaller but havier, I salvaged it's power system for my future Sharon, future

First thing is, Don't waste your MONEY $$$$ with something that will not bring you joy.

Second: what you expect from your E-Sharon?

Will you be happy just putting it up in the air? If so you'll spec a small sized motor like the Neu1506 mentioned and 17x10... ( very underpowered to my taste)

Do you want it a little bit hot, I mean a medium size motor like a Neu1509 and a RFM 17x13? (properly powered )

Or you want it a big hotliner? Then a big Neu 1512 RFM 20x13 is the way to go.

Maybe a rocketishh with Neu 1515 and RFM 18x19?

Please let me know what you want and how far you pocket will let you go...

André

This is the setup I fly with my Nan Alex XXL on 3S. I also ran the numbers for a 17X10 prop on 4S, but haven't tried this yet .
Both setups are really good for the Alex XXL, they fit very well the size and weight of this plane.

For a good setup you always have to consider the overall mass (inertia) and a appropriate pich for your prop.

Of course the high pich should give you high top speed but in a heavy model the peop will stall too long, nice sound but waste of watts, so a moderate pich like x13 to x15 is good here.

I'd love to check the room for bateries the E-Alex XXL offer, the conversion of an Glider to electric is not an option, except for a very light weight setup.
Could you please advise the maximum size of batteries it fit?

TKS!

André

I dont care about the cost

I am going to go with Kilweins setup to see if I like it

crazy power is fun but I really don't exactly need it

but then again I could be wrong

I cant tell how well it will climb unless I'm seeing it

I'll fly the 1506 1.5y but what is 1000w surge time, 20sec, 1min ?

Anyways, Kilwein says vertical, so I would prob be happy with a 45-60 degree climb with good speed and what, 50-80km/h ?

I do care that the Sharon has the legs to get up there and with minimal fussing around on the throttle, just punch and go

Plus on a windy day that the Sharon apparently likes, there would need to be enough juice to go upwind

The last thing I want is the Sharon struggling for height

Let me see if I can get a video this weekend of it on a vertical so you can see it.
I do like insane power also. Have one glider that does 5700ft/minute straight vertical.

Well,

5700ft/min isn't crazy, it starts getting crazy at 9000ft/min , little over 100mph but it's for another forum.

Anyways I really like your Alex XXL setup, That's the perfect sized glider, easy to transport and a big load of fun.

That gives a new meaning to Tim Taylor's MORE POWER!!
The only way I get the Sharon to 100+mph is in a dive and she howls.

I have a correction to the prop size, it is a 18x10 not 17x10.

Here is a link to old video.

OK,

So cost is not limiting, I just wann say that the Neu1506 is really small for that plane, all motors have a limited run time, time they build up heat and loose efficiency, then you need a loooong rest time before you run it again.
The big problem running a small motor in a big plane is it's always lazy and slow, then you keep pushing the motor and the result is a dead motor, frying either the magnets or the wiring.
Other thing is if you have a small motor in the nose, plus ESC and Batts and you still have to add lead, I hate carrying lead, what a waste!
When you have the correct size motor then you can have the right thrust, enough pich speed and long enough motor run time per battery pack.

I like my warmliners at 1000w/kg, close to 400w/lb , not lazy, not too fast also not too expensive, but watts don't tell all the story, specialy when talking about outrunners...

This website is very interesting, http://www.reisenauer.de , this guy sells some of the most interesting motor setups off the competition scenario.

Here you can check a true bench test with motor/batt/prop, you can figure out what might work for you, no guessing.

I have this PeggyPepper (Skorpion) http://www.reisenauer.de/artikeldetails.php5?aid=1623 in my Pike Perfect, it's pretty good but not perfect, I still need 60g on the nose and a heavy 3000mAh 3s Batt to balance, flying weight is 2400g, ordered this other http://www.reisenauer.de/artikeldetails.php5?aid=1594 , 30g heavier, needs a bigger ESC (a PHX125 is 30g more) , same batt, same prop (18x10 Graupner) will provide twice the thrust --- 3s - 11V - 18x10 G.M32, 7273 rpm, 107 Amp. 1187 Watt, Schub 7004g, Pitch. 111 km/h, Eta 78,7% - 15 Sek. ---
The nice thing is this is a Helicopter motor and is designed for "abuse".

For your application I would suggest this motor http://www.reisenauer.de/artikeldetails.php5?aid=1729 , it's a perfect match .
it's very recommended for planes on the 4-5m range and big props like RF 20x13 or 23x12 , I'm 100% positive.

Check it, it really worth a try!

Nice!

Do you have this video in POV version?

This link the guy uses a Neu-1509 4slipo and 15x10 prop, Still underpowered for my taste.

Dude,

The surge is just a few seconds like 8 to 10...

You say "punch and go" so it's more likely you need a Neu1512 or 1515 1Y, a good 6s, PHX 200 ESC and a 20x13. You also can go to a HV setup which I like more...

thanks,

I will try and measure the battery compartment, right now I fly it with a TP-3700-3S-45C LiPo
