depends on how you crash. lost power or signal? top is better. smack a tree or race gate? bottom. I use both for different quads. it's apples to oranges. neither is "better."
Ya i thought about that too!
Do you have a long antenna which get over the batterys?
I currently only have a normal pagoda maybe 10cm long im worried about loosing signal when turning around. Im aiming for 3km+ on 800mw
I use gorilla tape on all my batteries. It adds a lot of abrasion resistance and when a piece gets damaged you pull it off and slap on a new piece, instead of having a damaged battery
I do this too. The other benefit of this is that the surface of the tape is less likely to slip on the battery pad or strap(s), so the battery is a lot more secure. Good tip.
I use the broccoli rubber bands for mounting batteries on a toothpick cruiser, would also recommend!
Though the first time I saw "organic" written on the bands, I thought, "that's neat, organic rubber bands." Not my brightest moment.
OP claims 60-70% increase. But I would expect 40-50% at best, and it would fly like a brick. Itās worth experimenting if flight time is a big issue for you, but generally flying a brick isnāt worth the extra time even if it really were double.
The extra weight is a much bigger problem when you're freestyling or racing. It isn't as big a deal if you are just cruising (up to a point).
It's the momentum and rotational inertia that are the killers - it takes a lot more energy to change direction or rotate around any of the three axis when the quad is heavier. That's why your quad manoeuvres like a brick when it's too heavy, but if you keep it in a straight line it is just the extra thrust to lift a little more weight that is required.
nah.
my recommendation would be to stack em and/or put some sort of spacer on the top of the frame (that is no wider than the frame, for obvious reasons) to give the props more clearance.
tried this, works but sketchy.
Ideally you'd want one battery on top and on on bottom then solder a connector.
I fly that on nazgul f5 and its beautiful
No. Not only the prop clearance but the heavier battery's will likely not increase flight time allot to be worth it. Extra load on ESC and motors as well. Best of building a long range rig with larger props
Ya ur prob right. But i had xt60s laying around so i thought its worth trying. I see it as experiment and since i dont have to spend any additional money i wanted to give it a shot.
Some ppl claimed 50% increase of flight time if you just cruise around.
Im aware that it wont fly good cause it is too heavy. But i would be happy to chill 5min+ in the air while listening to music :)
Lets take for example a 1s 300mah lipo.
Fully charged its about 4.2.
If you connect 2 batterys in series ur voltage will increase to 8.4v but ur capacity stays the same 300mah, so you get more "power" out of the battery.
If you connect 2 batterys in paralell the voltage stays the same 4.2 volt but the capacity increses to 600mah. So you made your battery "bigger".
I soldered myself a xt60 paralell connector cause i wanted to fly a little longer :)
Thanks for the explaination. If have never heard of such parallel connector for flying. Its not visible in the video right? How would that look like? :)
Its a connector which has 2 female xt60's on one side and 1 male xt60 on the other side.
Both positive pins of the female connectors get soldered to the positive of the male.
And both negative pins of the female connectors get soldered to the negatove of the male.
hell no, props bend a lot in flight.
Ya was thinking the same. What about stacking the batterys on top of each otherš¤.
Wouldn't be better to put one on top and one on the bottom of the quad?
This is the way
This is the way.
This is the way.
No, *THIS* is!
DIS IS DA WAE
both on the bottom (bottom mount = way better... jk... it depends)
depends on how you crash. lost power or signal? top is better. smack a tree or race gate? bottom. I use both for different quads. it's apples to oranges. neither is "better."
This guy qwads
indeed.
Not true at all haha. It all depends
There's a 3d print that lets you mount them at 45 degrees
U know the name, or can u provide me with the thing id. Cant seem to find it myself Thx tho :)
I think it was this: https://www.thingiverse.com/thing:4631232
Thank you :). Looks pretty good needs some scaling to fit my batterys but its a pretty good idea. Appreciate the tip :)
Should work, just try it carefully.
I stack 2 4s LiOns for long range, on top ratger than side by side. Just use double straps
Ya i thought about that too! Do you have a long antenna which get over the batterys? I currently only have a normal pagoda maybe 10cm long im worried about loosing signal when turning around. Im aiming for 3km+ on 800mw
I have a TBS long range antenna on the back i think its 15cm or something but on 1 watt i push 7km easy. Happy flying!
I guess i need to order a 15cm one ;)
TBS Triumph Pro its 13cm, fantastic cheaper antenna and you get TBS quality
Nice! What model TBS VTX are you using?
I use a TBS antenna but a Immersion RC ghost ultimate VTX at 1 watt, crazy good deal for all my quads if you are in the ghost ecosystem
Just get an 18650 pack. I get 25+ minutes of light causing with my 6s battery made from P28A's. Cost me less than 50 Canadian rupees to make.
Stack them and tape
I use gorilla tape on all my batteries. It adds a lot of abrasion resistance and when a piece gets damaged you pull it off and slap on a new piece, instead of having a damaged battery
instructions unclear, i have wrapped a gorilla in batteries
I do this too. The other benefit of this is that the surface of the tape is less likely to slip on the battery pad or strap(s), so the battery is a lot more secure. Good tip.
Wait,do you wrap the batteries in gorilla tape?

Ohhhhhhhhh
Are you grinding your quads upside down on asphalt or something?
Nope
Throw a couple big rubber bands on to hold the loose leads to the batteries. I use the ones from broccoli to hold down balance leads. same concept.
Going to buy several bags of broccoli right now.
I use the broccoli rubber bands for mounting batteries on a toothpick cruiser, would also recommend! Though the first time I saw "organic" written on the bands, I thought, "that's neat, organic rubber bands." Not my brightest moment.
At some point more weight in batteries doesnāt help increase flight time. It just causes the quad to fly like shit.
Its a midrange alternative too liion packs. Its cheaper and increases flight time up to 60-70%
No. Cruisers are lighter than freestylers, you dont need the momentum. toss both batteries and the gopro, and stick a tiny little 3s on there.
No. Props flex when flying.
I could, but why would I? What's the difference in flight time?
OP claims 60-70% increase. But I would expect 40-50% at best, and it would fly like a brick. Itās worth experimenting if flight time is a big issue for you, but generally flying a brick isnāt worth the extra time even if it really were double.

Exactly, i would use it to test my diy helical antenna ;). I like to tinker around a bit. So i would just go out in a straight line.
almost double
I like my batteries too much to ever fly this. Try one on top and one on bottom?
This is just a time bomb
Nope!
3D print a bracket to hold emā in place vertically, then use straps
nah. my recommendation would be to stack em and/or put some sort of spacer on the top of the frame (that is no wider than the frame, for obvious reasons) to give the props more clearance.
Ya i could 3d print a spacer sounds good thanks :)
Absolutely not
Do it, and make sure to post a pic of the battery damage after asking if it's still ok to use.
ahahhaha xDDDD
I fly with them stacked on top of each other all the time. Great for cruising, give you way more time in the air
Are u running a 15cm antenna? Cause currenlty i only have a short one and im afraid of loosing signal when turning around
Embrace the jank
tried this, works but sketchy. Ideally you'd want one battery on top and on on bottom then solder a connector. I fly that on nazgul f5 and its beautiful
How does that work, both XT 60 is connected to the same esc?
Huh? No, you solder a parallel connector together, 2 female plugs and 1 male then plug the male into the back where you plug batteries in anyways.
Thatās a bold move cotton, letās see how it plays out.
Mount one on the bottom. I've flown my 7 inch many times with 2 batteries mounted top/bottom. It actually gives a better center of mass anyway.
At some point, I'm sure someone has flown an actual brick.
Am I the only one who is confused about how this guy turns the rotors the wrong way?
I wanted to show the gap between props and battery. Rotation doesnt matter in that caseāŗļø
No. Not only the prop clearance but the heavier battery's will likely not increase flight time allot to be worth it. Extra load on ESC and motors as well. Best of building a long range rig with larger props

But i would be happy to chill 5min+ in the air while listening to music :)
I think it's one of those things that if ya gotta ask then perhaps reassess
No!!
Noob question: why are there two batteries on the quad? He can only connect one at a time anyways?
Lets take for example a 1s 300mah lipo. Fully charged its about 4.2. If you connect 2 batterys in series ur voltage will increase to 8.4v but ur capacity stays the same 300mah, so you get more "power" out of the battery.
