180 or 250 for first drone build?

Hi all,

Planning out my first drone build. Have never flown a quad but have flown some micro collective pitch helis and have Phoenix simulator. I also just bought a CX10 micro quad to fly around the house. 

I was wondering if you guys thought it would be better to build a 180 class quad first or just go with a 250. I figure the 180 would be a bit cheaper, lighter, and more durable. But, the 250 would allow me more flexibility with upgrading and might be a more cost effective choice in the long run. I'm hopefully going to start doing fpv but to start was just going to build the quad without the fpv gear. 

Thanks for your input!

Hmm. I'm in the same

Hmm. I'm in the same situation. The 250, like you said, offers more space for whatever you want to add later. And if you want to use a larger prop size, you might not have enough clearance on the 180. There might be a more limited selection of parts available too. I see the 180 as somethimg that you get when you know exactly which parts you're going to add, and intend to build the sportiest drone you can. Others might have a different opinion though!

Battery life is also

Battery life is also something to think about - it's already pretty short with a 250 frame. The types of batteries you can fit on it get you maybe around 6 minutes of aggressive flying. It's going to be even less with what you can fit on a 180 size....but if you want all out speed and handling, the trade-off might be worth it.

Getting into FPV Racing

Have you ever flown before? If not I'd get something cheap like the Nano QX to learn the basics (THROTTLE CONTROL). It has the best flight controller for a cheap copter and is resilient to crashes. Building/buying a new copter is an expensive way to learn.

180 vs 250? I'd agree with blackstar that the 250 gives you more flexibility and is a great form factor for outdoor and indoor racing

Regarding battery, the standard 1300mah batteries on a ~250 will last 5 min if you are flying mellow and 2-3 minutes if you are racing/acro, C Rating should be at a minimum 35C but should be higher. 1800mah battery if you want to carry a gopro.

Learn about treating your LiPos properly so they last and dont become fire hazards (charging/discharging best practices)

Do you know how to solder, know the basics of electricity and can fiddle with code? You should if you wanna build one...

Have you chosen a radio yet? Few different options Taranis is high end but expensive, Turnigy 9xr is great and cheap... both have modules to use different frequencies

vTX? Choose 200mw or less, especially if you want to race indoors. Our racing league uses 25mw.

The zmr250 v2 from fpvmodel.com is a super resilient copter. I had a Vortex which was great for learning and outdoor flying but have just moved to the zmr250 and modded the arms to make it a 230 frame.

NeverHoverFPVRacing - great

NeverHoverFPVRacing - great writeup. There's certainly a lot to consider before jumping in. Ditto on the Nano QX as a good next step. In fact, there's also an FPV Nano QX bundled with FatShark Teleporter V4 goggles - http://gizmodo.com/review-i-had-an-out-of-body-experience-because-of-thi...

It's great for experiencing FPV around the home, and not having to think about where you can do your FPV'ing outside safely. Of course, if you do go ahead with the build, and are looking for a place to do it in the Greater Vancouver area, NeverHoverFPVRacing organizes regular racing events at (correct me if I'm wrong) Burnaby 8 rinks.

Thanks for all the tips! In

Thanks for all the tips! In answer to some of the questions:

-No I have never flown a quad before. Like I mentioned in my post my RC experience is micro collective pitch helis. I will also be getting a CX10 in the mail pretty soon. 
-I have a Spektrum DX8 transmitter which came with a free receiver. Would this be a fine radio to use?
-I have a little bit of experience soldering and coding. Part of the reason I wanted to build a quad in the first place was to learn more about both

FPV Racing

Yessir. We have a race scheduled for March 27th. Will be posted some info about it this weekend.

The spektrum is not a bad radio by any means. Several of the traditional brands such as Spektrum, Futaba and FrSky/Taranis have their propretiary protocols over the 2.4GHz spectrum which mean you were fairly stuck with the one brand but I believe the Spektrums use DSMX/2 which means you can use any DSMX/2 compatible receivers such as OrangeRx or LemonRX which make cheaper and smaller DSMX compatible RX. I'd figure out if your TX does DSMX or DSM2 and if your current RX is too big for your frame you can get cheap DSMX Rx from Hobby King for 10-20$.

I went with the Turnigy 9X as it had the JR module allowing me to put in different modules so I can run 2.4 GHz and 433 MHz. I use an OrangRX DSMX setup with my ZMR250 right now and havent had any issues with ~1000ft range.

preczion, we have a new

preczion, we have a new partner who manufactures custom and off-the-shelf airframes locally. They'll be joining the site soon, and starting up a new forum here. If you're not in a rush to get your frame, you might like what they have to offer. We'll be making announcements once they're up and running.

+1 for Turnigy 9X - it's

+1 for Turnigy 9X - it's probably the best 9 channel bang for the buck Tx you can get. I've been strongly considering that for myself.  Features are similar to others that are priced way higher. The Spektrum should be fine as well. If it were me, I'd probably stick with whatever I've got already and get the Turnigy later if I were doing more builds.
