TBS Discovery Pro

[jfro]

I was building a proto for a way to add coax arms to f450/550 plates but never made it come to fruition. now that kloner has the ultimate product for this i can say that one of the best configurations can now be made super cheap. You buy f550 plates and get 3 of Kloners arm sets, you now have a Y6. You could go X8 or XY8 as well. Both configs will enable you to avoid ever seeing the legs, arms or props in the FOV and have some redundancy. the Y6 also does extremely well in wind. Kloner, i think you're gonna be a millionaire off these things.

I assume one would need the 550 plates for a y6. Wonder what the weight limits would be on the DJI plates. Don't think they were designed for heavy lifting or high AMPs.

 

[kloner]

It'll build out to an 800 and lift a 3 axis nex with authority and power to spare. none of that 2814 stuff, big motors.... The only real limit is amps and the power distro, 6s would help keep that down..... after that, i'd get a real airframe

that's a 3520-400, bolts straight up on down to 2212

Looks very very good. So is the height for the legs enough if I have a 6S pack outside so it doesn`t hit the ground when I land.
Have you tried these packs or do they fit?

I was thinking going one inside for "short" time flights. And two packs in paralell for longer flight, one inside and one outside of the frame?

 

[kloner]

that battery is the one i use.....

no we don't, but the kits also come with just clamps without legs so you could use something like the dji 450-550 skid set and the arms still look like they were made to do that. I just land on the battery

 

[DucktileMedia]

Would my leg extensions work on your part?

 

[kloner]

never thought of that, they should, theres alot more plastic to bolt them to than a stock arm

"Also plastic don't dissipate heat from the motor." Perhaps theoretically true but this is not an issue with any heli I've ever had. Both your products look great. I'd say Kloner's got the advantage in that you can not only adjust the length but you can make your quad a coax and run your wires inside the tube to keep things tidy. Plus, when you crash a heli with plastic clamps and carbon booms, the booms generally break and the clamps will allow some sort of energy dissipation as to not transfer all the load into the frame of the heli. Aluminum arms would no doubt be a complete loss on a crash.

You don't think that heat dissipation is important until you do a little experiment on how much does cooling the motor only 10 degrees will improve your flight time( we do real engineering in the design of our products https://www.youtube.com/watch?v=tK6b6ON-hQ8). I agree that both products are good. It will just depend on what the user will want at the end but I bet the aluminum arms are lighter. I don't think that the plastic clamps or carbon booms will dissipate any energy in crash, if they do they are not stiff enough to get a good benefit out of it and if that is a concern, you should just stay with the stock plastic arms. I have crash a few times and I have not break yet the plates of my tbs disco.

Your arms are nice, I'm not trying to say anything bad about them I just dont think a motor should be that warm in the first place. Of course aluminum will dissipate heat but with all the airflow and low operating temps that should never be an issue to begin with. Maybe pushing things on a 3s system would get a little warm but....

I have seen enough carbon arms/clamps give enough in a minor crash to enable the pilot to rebuild the arm with no further damage to the main heli components. You cant honestly tell me if you crash an aluminum arm that you would be able to accurately bend the arm back in shape??

for you guys not following the tbs threads the gimbal mod levers are out. if you don't like the head banging (random gimbal movement) try one of these on for size.

Yeah, a y6 is a really nice configuration.

have you ever contributed anything useful to this board other than the other pink meat? It's really getting annoying

I have mine all upgraded, getting very nice results.

 

[CaptainJustice]

You can use up to 13in props. The arms only weight 67 grams and no major assembly is required. Also plastic don't dissipate heat from the motor.

Is that on the stock arms or the extended arms?

 

[jfro]

Kloner.

I'm sorry I'm too lazy to go back and read everything, but what is the weight w/ say arms to get you to 650mm motor to motor with your mounts both for the MR body and quad mounts for motors?

I don't remember, but are they 25mm?

What's current status on price and availability.

Thanks.....

 

[Maymidroix]

Extended arms.

 

[jfro]

Went and re-read.. 16mm. Haven't seen or heard anything on availability. Guessing we will hear soon.....

 

[kloner]

sorry i missed your reply jfro, these are 16mm carbon fiber, really nice material, big enough to fit 14" props and 3520 6s motors, trim down to fit your need. there super light, looks like 72 grams in parts per arm

they are in our hands and were working to get them to Patrick asap

looks nice.

I'm going to use avroto 3515's.
Are 14" props max for your arms or max for 16mm cf tubes?
I am guessing that hanging a gimbal off the front with prop wash hitting part of the camera or gimbal is probably not going to work? Because of this I am wondering if I need to extend arms out a little more....
Cam & gimbal is 2.2 lbs...

 

[kloner]

no, you won't need to extend it out any more. your looking at using 13" prop with a 2700-5000 mah, 14" with 10 amp hours slung. these things are crazy stable, like a mini skyjib looking thing

if you haven't bought the motors, get u5, there the new 3515 400kv motor, direct bolt cf props, nice....

 

[jfro]

Yes, progressing very well. Have some tuning to do with the new GotheliRC VX5 gimbal. Total weight excuding battery and fpv equipment is 1900 grams.

Kloner:

I haven't decided on a discovery frame or not yet. I'm testing with a f450 body with heavier arms now at 550mm. I'm looking at mounting the same gimbal that Boltzman has on his discovery. I'll be running a little heavier camera then the nex5, either the gh2 or Black Magic Pocket Cam. Gimbal & BMPC with light lens is probably 2.2lbs the way Boltzman has it mounted. I'm just concerned about the prop wash hitting the bigger camera/gimbal. I always mounted directly under bottom plate, never up front. Brushless gimbals are hard enough to setup in clean air. Will know soon enough.

With this setup, I'm testing on a 550mm standard quad with 14" props on my Avroto's 3515 (borrowed 4 from my x8) for testing. Avroto's are basically same as u5 and have the same prop mounting. I'm getting great flight times with 6s , 8000 mHa battery with the go pro and expect low to mid teens with the 2.2 lb gimbal/cam setup..

I'm also going to test on a 660 mm quad frame with 21.5mm arms (different frame which adds 1 lb) and 15" and 16" props.

I'm almost convinced to buy 4 more low KV motors, but it's cold and snowing here, so have time for some more testing before committing. I'm currently using a Naza v2, but just got a Pixhawk.

If it's half way decent, this will probably go on my hopped up quad in the future and won't really need the Discovery frame. With your 1" clearance, the Pixhawk might fit between the plates. It is 5/8" tall, but wires come out top and sides, so there may be some access issues.

I'm wondering if I could flip your mounts 180 degrees. I'm assuming you have the 4 mounting holes on top and two on the bottom. I wonder what would happen if I put (on custom plates) and had the 4 holes on bottom and 2 on top. This would allow easier access to the Pixhawk if I needed to remove the top plate to get to it.....

Just thinking out loud.

Are 14" props the maximum for a u5 on 16mm arms or can you use a longer 16mm cf tube and go with 15 or 16" props. Probably in the AUW 3-3.5kg range. I think on my f450 setup @550mm and bmpc, I'm at 2850g with large 6s battery...


Any chance AMP might be taking orders and shipping this week?
