Weight of normal shocky WITHOUT electronics?

[f3martin]

Hi Guys

Good ol flying giants to the rescue AGAIN!

I need to know how much a standard, 80cm shocky would weigh without motor, ESC, lipos and servos..

I have a couple of shockys but without worrying about weight (MG servos, big motor and big batteries)

But I have seen the new Donuts Models Nexus, looks real nice, and want to kit it out right, but the motor in mind is max 200g for 3d, (4.3g servos, 8g rx.) So I have a weight of 95.2g minus plane, prop and glue, sooo, hope its good news!

Thanks guys

Mine normally came out around 2.3 oz stock. With mods, I could get them to around 1.8 oz easy, and maybe 1.5 oz.

Yeah, I get 90 to 110 grams in a 36~38" (90~98cm span) shocky, all made of 3mm Depron. It really depends on the quality of the Depron you use and the gluing method.

I believe that if you use good quality and light Depron (how it normally is, except for some cheaper varieties available down here that aren't) you should be able get a 80cm span one weighing in at 80 grams or less without much effort.

My 80cm span Loco Competition come out under 60g usually glued with foam safe CA, this with original Depron. rtf weight is 120-130g for the "heavy" versions and around 105g for the light ones.
Some fanatics in Germany glue their shockys with Uhu Por foam contact cement, they say this saves maybe one or two grams... dunno.. not worth the trouble IMHO

Once you learn how to use UHU Por it is fantastic. I buy a big tube of it regularly. I use it to hold down foam on gassers for regualtors, receivers, tank, it is great stuff.

The trick is using it is to use it as contact cement , and prefit all parts.

I have never weighed an Ikarus Shockie naked. But I will, I hope the neighbors can't see in the windows......

What do you think of this motor setup....http://www.dualsky.com/main.asp?mainset=31

Just under an ounce total...esc, motor,prop saver....I got the 2S setup 300mah and 450 mah .

True indeed. That is exaclty the problem, beeing a contact cement it becomes difficult to exaclty align things sometimes...

Hi Guys
Thanks for the ideas
Boshhoss hit on the motor I had in mind! the Dualsky 70W brushless with incorporated ESC and prop saver for 26g, but it claims it has a max 3d weight of 200g. Does anyone know this motor, any comments? I would probably be using 3S, has anyone tried it on 3S? ( max 200g is on 2S)
The model in mind, is the new Donuts Models Nexus, I saw it, I wanted it! Does anyone know it? any good?
I figured 4.3g servos on each aileron (.7kg torque)
And 6g servos on elevator and rudder (1.3kg torque)
Hitec 8.6g 5ch rx

And the lipos I have are 450 and 600mAh 3S, and one 350mAh 2S

I am the first one to admit I dont know what im doing with electric flight, so any comments from people who do are greatly apreceated.

Many thanks
Martin

I have not got mine together yet, be sure to choose the right motor for the cell count you want to use.

I went with the 27t motor for 2s operation, to save a little battery weight. 200g is just under 8oz...no problem getting a shocky to that.

Mark Grohe of 2DogRC talked with me at length about the motors. 300mah 2s with a black GWS 7x3.8 prop makes a 6ozer ballistic on the 27t. on the 33t 450 3s or 600 3s , same prop ...is the setup.

I wish I had gotten a few more. I am surely going to tear one up at the dome.. Airplane-Animal Dome. Fly NOTHING you love, only expendable airframes. LOL.

I am going to throw one on a beat up/heavy shockie just to try it out. ....I will post later.

Hi Bosshoss

Thanks for the great info, just one small querie, you say "on the 33t 450 3s or 600 3s , same prop ...is the setup" could you please clarify the "...is the setup"

As I will be using 3S, I guess I need the 33t, which, with being less Kv means is the 3d version?

Thanks for all the help

hello everyone,
f3martin, there is no need to fly a 3s setup on the nexus!it's too heavy for it!
I think it would be better to fly a 2s setup since it would be great if it weights under 140g(maximum weight according to Donuts)
One of my friend flys a Manta (equivalent to the nexus, 135g ready to fly) with a 11g flyware motor and the power is enough for 3d in 2s.
The clue for a better flight is to save weight, not to add extra weight, especially with these birds.
Hope it will help you,

Hi Tetre73
I have received the nexus, and it looks great, the carbon struts for the wing dont leave the wing as rigid as i thought they would, but apart from that all looks good.
26g Dualsky Motor + ESC, max 200g
4.3g 0.7kg servos
8.6g hitec rx
Lipos, what I got! I have a 2s, I will try with all setups, if there is a real difference I will get a couple more.
tetre, I am used to flying a 350g Ikarus Yak, weight doesnt worry me too much, however I a, trying to get the nexus a bit closer the mark.
I thing the fingers make the plane, not the weight, the weight just helps..

I am hoping to get the nexus under 160g AUW, if the bits ever arrive!!!

Thanks
