I hate to say this Derek but I think those motors on 5x3 props running 3s are a bit under propped.
However the learning curve of an FPV mini may have you go through them reasonably quickly.
6" props or at least 5.45 May be more suited.
On 4s that thing will be a rocket ship. :)

Maybe the 5x3s are not such a bad idea. :)

Thanks for that, Stambo! I just checked the reviews on Hobby King and someone mentioned that 6" props won't fit my Dart 250. I've seen arm extensions for mini quads that will allow the motor to be moved out a bit more to allow for 6" props. Looks like I might have to order a set of these extensions.

Another update....I just got an email from multirotorsuperstore.com saying that my order has been shipped. So...from them, my Acro Naze 32 and props have been shipped. Awesome!!!

Oh my gosh, I'm getting so excited! As posted earlier...I ordered 4 motors and 4 esc's from www.buddyrc.com and about an hour later, I got an email from them saying that my package has been shipped. Fantastic!!! I ordered an Acro Naze 32 and 32 props (orange and green, CW and CCW) from www.multirotorsuperstore.com and a few hours later, I get an email from them saying that my package has been shipped. Once again....Fantastic!!! The "Happy Dance" is happening, for sure, lol

We'll just have to wait and see what all parts show up first, lol. I'm very excited about it all. All I need for my mini quad (I think) is a bit of wire, FPV gear, and a Spektrum rx.

After ordering my parts on Thursday, I was browsing around and found a Spektrum AR6210 with satellite rx for sale for a reasonable price. Once again, I clicked the "Pay Now" button, lol. So, that should be here soon.

I just checked my mailbox. No bills, but there was some "junk mail"......and two white boxes. OOOOOOO, I know what those are!!! The 4 motors and 4 esc's that I ordered, two days ago, from www.buddyrc.com are here. As well as the Acro Naze 32 (with right angle pins) and props that I ordered, two days ago, from www.multirotorsuperstore.com are here. Very very cool!

Now....I just need to find a realistic reason to NOT go to work tonight, lmao.

My Spektrum rx just showed up for my quad. Very cool! My camera has been marked as "shipped". Very cool!

Now, i'm just waiting on my vtx, vrx, and antennas. I may have to hunt down some LEDs, but I should have everything really soon and then I'll start the actual build and electronics installation.

OK, NOW I'M SUPER EXCITED!!!!

I just got an email from GetFPV.com. My Immersion 5.8ghz 600mw vtx, Immersion 5.8ghz 32 channel rx, and Blue Beam Ultra antennas have been shipped. Whoo hoo!!!

I got an email from StoneBlueAirlines, earlier today, saying that my 600tvl mini cam has been shipped. Whoo hoo!!!

My Spektrum rx showed up this morning. I have my motors, esc's, props, and mini quad here already. I think that's about everything except the two Mobius cams that I ordered and I want to add some LED's. Oh...and a buzzer of some kind.

It's all coming together!!!

Yeah make sure you put a buzzer on it Derek.
You can lose one of these a couple of meters away in long grass.

This got me thinking again. I have the 2100kv motors and 5x3 GemFam props. Stambo says that the quad may be under-propped on 3S. Stambo is much more experienced than me so I surely have no reason to doubt him. My motors are rated for 3S and 4S. The ESC's are, too. I already have several 3S 1300 35C batteries, so there's no reason not to run this quad on 3S...especially during testing and beginning flights. I'd like to run it on 4S, too, but that will be once I've gotten accustomed to it..

So....on 3S, would it be ok to run 5x4, 5x4.5, or 5x5 props? Without arm extensions, my Dart 250 will NOT allow 6" props. No chance at all.

What do you guys think???

Probably be ok on the 5x4.5s.
I would get a selection of each and try it, they are cheap enough.
Check the motor and ESC temps after a few short flights and decide what you will run it on.
Just remember that gains may be different depending on what props you are using.

I run my 3s 2400kv motors with 5x4 so the 5x5 might even be an option.
Don't be too worried Derek, it will fly on the 5x3 but I am thinking with a bit more pitch the motors don't have to rev quite so hard and you will have a bit more punch.

Thanks for that, Stambo! It sounds like I need to go click on that "Pay Now" button again and order a variety of props :lol:

What kinds of temperatures should I expect to see? Or better yet, what kinds of motor temperatures are "too much"?

I just ordered another pair of 3S 1550mah 30C batteries, LED's, and a hat.

Unfortunately, I'll have to order a variety of props from a different company.

I've looked at:
multirotorsuperstore.com
hobbyking.com
getfpv.com
readymaderc.com

All of the above either don't carry anything but 5x3 props or they are out of stock. I need a few other suggestions for places to look for 5x4 and 5x5 props (CW and CCW). Any thoughts?

Readymade RC have lots, check the link below, they have 5x4 and 5x4.5 bullnose.
You want Direct Drive HQ Prop - Glass Fiber, not the carbon composite ones as they are too brittle.
I use the 5x4 from there.

Ok....just an update....my ImmersionRC 5.8ghz system showed up today from www.getfpv.com and my FPV camera showed up today from www.stoneblueairlines.com. Very very cool! The only things left to come are a bunch of 5x4 and 5x5 props from www.readymaderc.com and some LED's and batteries from www.buddyrc.com. I'm going to head to the hobby shop in a few minutes to get some screws that will mount the motors to the quad and I'm gonna see about getting some parts installed tonight and this weekend. Very Very COOL!!!

Naturally, here comes a question...we've discussed parts for "this" and parts for "that"....what about transmitter setup? Where do I begin with that? If I remember right, my DX8 will be setup with a Plane profile. Easy enough. Is there much else that I need to setup in the tx?
