5'' Freestyle

[blissful walrus]

My first build...

Frame Geprc Mark 5 DC
Motor XING2 2207 1855KV
ESC/FC SpeedyBee F7V3 50A Stack
DJI O3
Geprc GPS M10
Props Gemfan Hurrikan 51477 5.1X4.77X3

What do you think

would you change something ?

[hardy kiln]

where did you put the leds?

[topaz lark]

I wouldn't use a speedybee stack (they crappy), nor would I use a deadcat frame

[blissful walrus]

i am still working on the led setup

[blissful walrus]

i use the deadcat because i like to have a gopro ontop

[topaz lark]

squished X is a thing, the gopro isn't going to see the props with squished X, even on trueX with a bit of uptilt

[blissful walrus]

but I never heard that the Speedybee stack is so crappy... which one would you use

[topaz lark]

depends on the budget

[blissful walrus]

high

[topaz lark]

hobbywing xrotor 30x30

[blissful walrus]

what do you think about GEPRC TAKER F722 BLS 65A V2 STACK

okay maybe a bit high amps

[topaz lark]

the xrotor is 65A too

and the xrotor is better

but just fly the speedybee one until it goes kaboom, then get a better esc/fc

[blissful walrus]

i think the Speedybee will handle the XING 2 2207 1855KV really well

[topaz lark]

the esc and fc doesn't matter for how well a quad will fly, only for how long

[blissful walrus]

i know, but considering the kaboom

[cloud sail]

your stack is most likely fine, the speedybee f405v3 was the really bad one

[limber oriole]

I actually have f405v3 and have 0 problems. also my friend has one, 0 problems.

I have similar build, only with Volador II VD5 instead of Mark5 frame. It's heavy, but it flies nice, as I don't use GoPro

[topaz lark]

"I never had issues with my unit"≠"best thing in the world, it's indestructible no one ever had issues with it it's awesome and everyone should buy it"

[limber oriole]

Ok, if the budget is unlimited, then that's a valid point. But hobbywing xrotor 30x30 stack is 120€ and f405v3 is 70€...

[topaz lark]

That doesn't mean it's good, and there are plenty of much better options than the v3 stacks that are cheaper than the xrotor stack, I only mentioned it because he said he had a high budget, but diatone and skystar have a lot of stacks cheaper than the xrotor, and much better than the v3

[limber oriole]

I was not aware there are a lot of failure reports on v3. If so, then me and my friends might be lucky with ours. But I haven't really heard anything about v3 failing a lot.

[topaz lark]

The f405 v3, besides being made with shitty quality components, has an actual wiring flaw where if you use the osd and blackbox at the same time the fc craps itself
It's a really stupid design and it's in general just bad, especially when you can get something that's much better from 30$ more with skystar and diatone (granted they also do some 70$ stacks, that I would also use over the v3, if budget is really tight)

[limber oriole]

I know about the osd-blackbox issues, it's stupid mistake on their part, but I don't really care as they do not affect me. If I needed blackbox, there is v4 that has that fixed. And crappy components are crappy only if they fail a lot, and I have no information proving me they do. I'm not saying it's perfect and I'm in love with it or something. I'm just saying that it's cheap and it works well for me and for most people, as far as I know.

[topaz lark]

Yeah but you can get much better for not much more, so there is no reason why you would get a speedybee stack, and there are quite a few people that end up with blown up escs, the USB falling off or the fc just dying, not all of them will die in 2 weeks, but that doesn't mean anyone should buy them

[limber oriole]

you can get much better for not much more

If the stack fulfills all my needs, "better" does not exist, so any extra money money spent is wasted.

there are quite a few people that end up with blown up escs, the USB falling off or the fc just dying

See, this is the info that I am now aware of. If this happens a lot, then the components might be "crappy" and I am just lucky.
But you must take into account the volume this stack is sold in. If there are 20 failure reports on a stack that sells in 10 000s, that's better than 5 failure reports on stack that sells in 1000s.

[topaz lark]

But it's not 20 failure reports on a stack that sells 10,000 tho, I don't have an exact number, but it's fairly frequent and not that many people buy the v3 anymore,
And even if your stack currently suits your needs, spending a bit more will just mean it will stay alive for longer, it doesn't necessarily mean it will be able to do more

[limber oriole]

I hope mine stays alive for a long time then, so I can say I saved some money... 🙂
