Day 2 with the Morphite. PIDs are getting closer.

Each DYS 1806/2300 motor ($14) produces about 480g of thrust with the HQ 445 Bullnose props. Motors come down slightly above room temp.

Very fun quad and tough as nails. Working on dialing the PIDs in.

2206/2000KV motors + Nanotech 2250/130C

Vtx: IRC 2.4 700mw

Nearly 11 minutes putt-putting around. Ignore the first 1:30 minutes of flying. . . my Gyro was off. I recalibrate @ 1:30.

Anyone who's interested in the penetration of 2.4, watch the whole thing. I fly well below my LOS and to the extreme part of the field.

I am impressed. I only just moved over from 1.3. I'm totally sold on 2.4. . . for the antenna size alone but the reception was really good. There were also a couple guys flying rigs on 2.4 during this sortie and I didn't have any issues on video.

It was snowy in the corner of the field but I could still make out what was what enough to still fly safely.

I think the unofficial time was 10:40.

Of course I always get out to fly with only 30 min to spare. Really liking this quad.

It was fun until I lost my video signal, thanks to a loose SMA connector. Landed safely.

Shot this right before a failsafe crash this weekend. I'm all over the place but it was sure fun. Needs a little tuning, you can see some bumps on the WOT punch outs.

I used a some aluminum from an old motorcycle license plate holder. It's basically a square. Cut it with aircraft sheers, then file the sharp edges down with a mill file.

I used the bottom plate as a drill template. Mark the first hole with a punch, then drill it and attach it to the plate with a screw and bolt. Then line it up with the bottom plate and use the plate as a drill guide and drill out the second hole. This way the plate will line up perfectly.

Choose your color, wire them up and go. I'm using a 12V out from my step-down. They're super bright on 4S when coming right off the LiPo. They're rated for only 12V, so not sure how long they'd last on 14.8s. They're cheap enough to experiment with. Connect everything up with some JST plugs. I get these from getfpv, readymade or wherever(10 pairs to a bag). Very handy.

Hope this helps any other fellow racers!

Rushing to get a flight in as the sun was setting and the temp was dropping!

This little Diatone has been to Thunderdome and back many times. Moving her guts over to an RD230.

DYS 1806/2300KV (tough as hell motors, runs even on 4S)
Hobbywing 10A unflashed ESC(Simon who?)
RMRC 200mW 1.3Ghz vTX (great for prox bashing)
PCB 1.3 Antenna. Not the greatest vTX antenna but it's takes a beating and is out of the way. Great antenna if you want to not care about crashing.

Building a spec racer for my local group here in Raleigh.

To be allowed to race, the quad must run no more than 3S, spinning 5" props.

Hoping to get the maiden in this evening.
RD230 FPV Maiden* (1 min 37 sec)

Here's the evolution of this frame. I've upgraded to a dirty/clean version, flying only 4S with HQ545. It's a screamer. It's nearly as fast as a lot of 300mm 645 rigs, and a lot more maneuverable in close prox stuff.

Out of the way.

Using a Kristapps switcher plugged into one of the 3 remaining channels on my IRC 4Ch Lite.

I've used this camera on my QX9 before . Works great when it's overcast but direct sunlight destroys the image(no IR filter).

1. Remove the Pivot Foot Knob, replace with M5X~10mm bolt+2-3 washers+M5 prop spinner or nut(local hardware store)
2. Cut Center Point from Pivot Foot
3. Reattach Center Point with M5x~10mm bolt (from step 1)

As a circle cutter, this device is not so great. As a prop cutter, it works very well.

Losen the M5 bolt and more your prop to nearly any length you desire. The rail is ruled and actually nearly accurate. However, I've scribed lines and dyed with india ink to label the various prop lengths for my rigs.

I'll add some pics of mine soon. Away from shop atm.

PIDs were a little tight and was getting some oscillations. I'd tested this setup a few days ealier (WOT punchouts only) and didn't see any but I'm guessing the TPA was doing it's job to hide them.

Love this location. This is only half the property. The 'back nine' has more undulation, berms and quite a few trees interspersed with plenty of area to move around. Only a stones throw from NCSU. Heaven.

Punchout test with HQ645. Did a 4S test as well (1300mAh) but it was a very saggy LiPo and the output was actually less than the Lumenier 3S used in the below video.

Rough dimensions of the quad are 11" long, 2.25" wide, symmetrical square, 300mm diagonal M2M.

More to come. . .

It works but the plates need to be scaled down some. She was a rascal in the air, so I just kept the flying to circles.

You can tell I'm not really on the throttle at all and she's really moving along at a fast clip.

Overall, impressed with the speed of these motors. Running ancient HK F30A SK ESCs. The FW is from Dec, whatever version that was. No issues with synching at all.

I'll update the blog once I figure out the sweet spot on scaling the QX9 plans. This will be a nice cheap, smallish, fast rig once it's complete. I'm guessing the size needs to come down around 10-15%.

**EDIT: did some tweeking on the geometry this evening, swung the rear booms fwd a few degrees, this gets close to perfectly square symmetry. Will test again tomorrow.

**EDIT II: ok, that did it. Handles a lot better, acro is good, hovers nicely. . . only issue now is the weight. I could make some hardware changes and get the weight to 978g(2200mAh 4S) and 1059g(3300mAh 4S) but I might consider moving to 2213/2000KV motors instead.

ADS400, QAV400 or QX9 sitting in the corner, unloved? Ditch the long booms and cut some 1/2" square Alum ~5" replacements. Mount 2208/2000KV + HQ645 props, standard 1/2" standoffs and you've got a super inexpensive rocket. I'll be posting some proving ground video soon.

In the meantime, here are a few WOT punchouts from earlier. This was LOS and it turned into a spec so fast that I lost my nerve but you get the idea. No oscillations, no jello, only speed. I should add, this Naze was currently tuned for 2216/1200KV + HQ950 (clipped to 8"). It will tighten up a lot with custom PIDs.

Standard QX9 plates using 1/2" 6061T6 square Alum tubing booms cut for 6" props.

More to come on this. Hope to get her out in the open to see what she can do later today.

The quad can be easily weight optimized more than it is right now to get the AUW in the 875g-950g range. Smaller ESCs for one, shorter GoPro platform, Vee Antenna, lighter flight cam, CF booms.

G10 Plates: $20

Started with HQ530 props, then moved to GF530. Wow, HUGE difference. . . tons more grunt with the GemFans.

My favorite prop is the HQ540, but I've only got a set or two left and I'm hoarding those right now. The 540 performance is nearly as good as a standard sized acro quad on 845 props + 1100KV motors. Great prop.
