Solved Need help with custom "power pack" I made

So instead of buying a power pack, I checked the internet for similar parts, and it seemed to work. Would anyone tell if if these would actually work together? They would be going in a Mighty Mini. Very new to the whole DIY stuff so I have no idea if these work. I tried to mimic Power Pack F here.

Motor + 30 AMP ESC (1800 XT60) - https://www.ebay.com/itm/A2208-1100...p2349624.m46890.l49286&mkrid=711-127632-2357-

9g Servos - https://www.ebay.com/itm/10pc-9G-SG...2349624.m46890.l49286&mkrid=711-127632-2357-0

6x3 CCW Propellers - https://www.ebay.com/itm/321818341502?hash=item4aedde307e:g:PFAAAOSwHnFVuCmM

850mAh 14.8v Battery w/XT60 Plug - https://www.amazon.com/dp/B07DNS12LM/?tag=lstir-20

2 Servo Extensions - https://store.flitetest.com/20cm-servo-extension/

Linkage Stoppers - https://store.flitetest.com/linkage-stoppers-6-pack/

XT60 Y - Lead (Not sure if it's the same as a Y - Lead) - https://store.flitetest.com/xt60-power-y-harness/

Any help with this would be appreciated

the xt60 y lead would be used on twin or something of that sort if you wanted to use one battery
you would also need a a servo y lead like this if your flying something with ailerons (if you have a 6ch reciver you can plug the other servo into channel 5 or smth I just use a y harness) other than that you should be good

As @Ligbaer beat me in saying, the Y-lead is not the same as a Y-harness. Yours is for batteries, while the one you need should be for servos.
I would reconsider the motor and battery. 4s (4 cells) is a little overkill for a mighty mini.

Here is the process to see if things are compatible.

Start with the motor, you need to find out how many amps it is rated for. Then select a prop that will not exceed the amp rating at the voltage you intend to use. Check the specs on the website.

Next, select an ESC with a higher amp rating than the motor will draw. Give yourself some over head, a minimum of 3-5 amps, as the ESC will also be supplying power to the servos & Rx.

Finally, select a battery that can supply enough amps to power your setup. The amps a battery can supply is calculated, mah/1000 x C.
Example: a 1350mah 30C battery can supply 40.5 amps (1350/1000 x 30 = 40.5)

All of the amp ratings are do not exceed numbers. If you exceed any of the amp draws, the weakest link will give out first. The battery needs to be within the voltage limits of the motor & ESC's voltage rating.

The last thing to think about is, will all of the connectors fit. If you can solder, it's a simple process to change a connector. If you can't solder, it's a big problem.

Some of this doesn't really work together and you would need to reconsider some of your part selection. The motor and ESC is only rated for 2-3s, so using a 4s battery won't work. You should go down to a 3s or a 2s. Also, the servo choice is a bit big. While 9 grams will work, 5 grams will work much better in most of the FT minis and will work better in general for a smaller plane. Also on the topic of size, an XT-60 is pretty big for a mini. While the XT-60 should be fine, an XT-30 would work better in terms of getting it to actually fit in the plane. Also once you choose a smaller battery you may find many 3s 850s with XT-30s and not XT-60s (though I think RcBattery.com sells 3s 850s with XT-60 plugs).

If you are new to the hobby then my recommendation would be to just get an F pack. In your other thread you mentioned how it was out of stock at the moment, but waiting a bit for it to be back in stock would definitely be worth it as you are guaranteed to get a set of great quality parts that will work together with any FT plane (and many community designs as well). In addition, getting the F pack would allow you to learn more about planes and electronics so that soon you will be able to compile your own set of electronics and be more confident while doing so (you wouldn't need to ask for help in ensuring compatibility since you will already have the knowledge to check it for yourself).

the motor is too high of kV get 2450kv or 2200kv that's what I use for my mighty minis same company and get 3s battery and a servo y harness the harness you got is for adding 2 batteries mah

While you could go with a lower kv and it would work fine, the 2600kv isn't really too high. It's just a couple hundred higher than a normal F pack and since the motor is bigger anyways it might even have a little boost in power.

I use a 2450 that's more than enough on 3 cell

Yes, like I said, it will work. It might also be more than enough. None of that makes a 2600kv "too high". If there is no weight penalty but more power then why wouldn't you want it. When I first entered the hobby I had to pick between a 2s and a 3s, and a wise guy told me something along the lines of this: "take the 3s, if you don't need the power, then don't use it. If you need the power, then you'll be happy you didn't pick the 2s."

After looking through the thread, I'm probably going to just buy the pack. Someone posted one in stock and I'm about to buy it. Thanks for the help.
