V tails are pretty slick, Ive seen some that are really fast in forward flight.

I thought about building one kinda like this:

Ok, that's really damn cool. Does the non-inverted V-Tail work with just standard X-Quad configurations on most flight controllers?

I think I'm done trying to build tricopters. I built a 180g mini tri last night (based on this thread) with a KK2.0 so the wifey has something to fly with me, and the bastard is super unstable. I can pick up one more motor and one more ESC and turn it into a micro V-Tail and win. Maybe. I'm getting tired of buying servos regardless.

On board video, following my neighbors miata. It looks like I'm really close to stuff but a lot of that is the super wide angle of the gopro.



also, I was drinkin a little and managed to hit myself in the head with the prop a few minutes after this. Got two strikes, didn't hurt too bad, but man it bled, lol. Going to probably build some blue foam prop guards and use some balsa or something to make them a bit more rigid.

also, I'm not the best pilot... and I'm still intimidated by the thing so, don't expect to be too impressed by the video, lol.

Haha! Awesome

Yeah, be careful with the flying lawnmower. I got bit pretty hard by a FT Flyer not long ago. I lost control of it in the wind and had to bat it out of the sky before it hit my now wife in the back of the head. I still have prop scars on the inside of my arm.

Funny thought: because I know the pitch of the prop, I could probably measure the distance between the scars and get a reasonable estimate of airspeed when it chopped up my arm.

Just ordered another motor, and esc to do a vtail.

I will be doing something similar to David's with the vtail bat-bone, but with his frame rather than the bat-bone. Pics to follow soon.

And just for the hell of it.

From what iv'e been reading, the KK2.0 is the easiest to do a v-tail since the motor layout is already in the firmware.

As of 6+ months ago, kk2.0 was the only one. Others might have it also now, but since I have a kk2.0, I stopped reading.

I have the Flitetest rotor-bones motor mounts/landing gear now. They are all great, but the tricopter tail assembly is a little weak, and i'm tired of rebuilding it.

The delrin they make it out of is foolish. It's simply not a stong polymer. I don't know why they wouldn't use the G10 that they make the center structural plates out of.

Oh crap, I thought it was the same G10 as David's Tri center frame. Well, looks like I'm back to making stuff out of 3mm hobby plywood again.

Yellow: I'm very interested in however you mount the 2 rear arms, please take good pics so I can duplicate. I'll probably disassemble my trashed quad and see if I can build a V. I may need a motor though, I still haven't evaluated after the last wreck.

Rotorbones motor mount itself is made from 2.5mm G10, but the landing gear portion of it is delrin.
I did break the 2.5mm G10 once, but it was from a crash that I would have expected more damage.

The David Windestal body is made from 1.5mm G10

Looks like the MultiWii and the KK2.0 will do V-Tail, and also the "swept back/inverted" V as well, but there are a grip of stuff that needs to be edited.

If anyone here is on the fence about the products from Flitetest, go for it. They are all well made, and there customer service is second to none.

I placed an order a week ago for some replacement parts. (before I decided to go vtail). My order was wrong, so I emailed them. 30min later, I got an email back saying he was going to have the parts in the mail the next day. I told him I was going a different direction, and needed more parts anyways. He made the order right, didn't charge me for the extra parts I wanted, and had them in the mail first class the next day.

Figured Id share that with y'all.

I've been wanting to get some of their planks... but at the end of the day I don't have room to really fly one... So I keep ordering crap for the tricopter. Just ordered a set of fatshark dominators and other FPV crap and more batteries and another charger.... Damn if this stuff isn't nearly as expensive as cars, lol. Its just addicting since theirs so much decent cheap stuff out there. Minim OSD for $20? why not tack that on to the order too, $7 landing gear? ok. lol.

Yeah and **** adds up quick! I have a feeling that if my Reverant-Squirt showed up I'd probably get back to work on the car, but I'm stuck waiting for an ECU.

I've been trying desperately not to buy FPV stuff, we'll see how long that lasts. I may actually get around to rebuilding my quad soon.

On a related note:

I have 4x SunnySky X2212-9 KV1400 II Brushless Motor I bought from BuddyRC last month. I now realize this is way too many KVs for what I'm doing. These are new in the box, never installed or even powered up. I unpackaged one to check fitment but thats it. These are the newer SunnySky X series Version II motors with the 3.17mm shafts.



Each one includes the accessory pack and the prop mount, though I would recommend replacing the regular nut with a nylock. They do NOT have the goofy long shafts sticking out the bottom.

Manufacturer has specs here: X2212-Zhongshan RC SunnySky Model Co., Ltd

I sent several emails and left phone messages for the guys at BuddyRC regarding exchange/RMA, but I've got no responses. I doubt I'll get an RMA at this point so if any of you are interested, I'll sell them for like $65+ $5.80 Small USPS Flatrate. I was going to post these up on RCGroups, but I figured I'd rather deal with you guys (believe it or not.)

These are damn good motors, they just aren't right for what I'm looking to do right now.

I can't find any details on them? 3 cell? You have resistance and no-load current data?

Yeah, I know. The manufacturer hasn't updated the specs for the Version II motors yet, but they have to be pretty damn close to the Version I motors:

X2212 KV1400 no load current:10V-0.9A weight:56g Diameter:27.5mm Length:30mm Shaft Diameter:3mm



I can confirm the external dimensions

I know the guys running the 980kv version and pushing 4S with no problems, even though the manufacturer only lists 2S-3S data. I've seen data for other X and A series 2212 size SS motors that says 160-200W, but again, manufacturer data is sparse.

Im thinking of upgrading from my DT700, but 1400kv is pretty high.
