Weight

[woodscra]

What is the weight of your 516 RTF without battery?
Please share if any additional items are added like a non-ESC BEC, RX batt, batt backup.

Anyone have the weight for a "stock" config with MKS servos, rail blades, HW 120A ESC, aluminum boom?

Thanks.

Here you go,

516 with alloy boom  2234g
516 with cf boom 2188g
(includes battery tray & strap 36g)

Xnova 4020-1350
HW 120 V4 platinum
MKS 9767 cyclics

No extras.

I knew all this would come in handy some day.

Great, thanks!  With AUW 2860g, what head speed?  Does it begin to feel heavy or what weight do you think that would be?  Questioning my batt choices and whether to add an RX batt.

I have headspeeds 2400, 2500, 2600 using a 17T pinion. That keeps it in the 84-90% range on the esc.

I fly big air and lazy 3D mostly 2400, some 2500, rarely 2600.
How it feels is subjective, depends on flying style etc.  But I've never sensed heaviness or sluggishness at 2400 and it gets more responsive as headspeed goes up. Have also used gensace 5000 65c packs which bring flying weight to 2934g and the heli felt much the same as with a 4400 pack.

Mine is 2950g all up and doesn't feel heavy at ~2350rpm.

I think the extra weight is coming from heat shrink on the servo wires and a battery spacer I made. Batteries are a little wide and rubbed the slider guides so I lowered them on the tray a tad. GensAce 5000 45C. I used fiberboard and servo tape and am a bit surprised it's that much more heavy than others. Especially considering I have the CF boom and CF canopy BUT no performance issues so I'm good.

Really no difference in weight with the carbon canopies. I thought there would be as well but nope :-)

Cheers

Thanks Alan,
that takes care of buying a cf canopy.
My factory canopy is 90g with grommets fitted

I'm showing 98g stock and 86g on the CanoMod.

Edit: When I think about it, I'm questioning the accuracy of this scale. My fiancé loves generic stuff from amazon, haha! I'll have to pick up my own and reweigh everything.

Your scale is close enough. We are talking a few grams. Not ounces :-)
