Armattan Tadpole - HD Edition

Holy cow, another Armattan Tadpole? Really?? Yes, well, guilty as charged, what can I say? Everyone should make them, they're great.

Anyhow, I have been delighted by the Tadpole I very recently built (yeesh, this hobby and bank accounts...), but I have been constantly disappointed that such a fun little machine is relegated to goggle DVR for post hoc video. And that's no fun on the big screen TV, right kids?

So I wondered if it would be possible to squeeze on-board HD recording into a Tadpole, and after doing a bit of digging, realised that the fancy new Whoop boards that are showing up could be just the thing; Armattan make a Whoop board adapter plate for the Tadpole, so they obviously want you to engage in this sort of mad science. I ordered a new frame, a passel of parts and when they arrived, did a certain amount of Tetris-ing.

As such, it is with considerable pleasure that I present, fresh from it's maiden flight in the park this very evening, the Armattan Tadpole HD; 78g of 2.5" Acro flying fun, recording all those daring, but smallish-scale, aerial japes in silky 1080p@60fps. I thank you!

This is the maiden flight, well, 3rd pack, and it looks like this build is going to be just fine. In truth, I didn't really expect it to work very well, that I would have to build shims to raise the plate heights to get things to fit, but in the end, it all squeezed in. It is a bit messy, but it works. The hardware is supposedly 3S-4S capable, I'm running 3S here and it lacks a bit of punch, the ground does arrive somewhat faster than anticipated. Not terrible, but a bit alarming at first. So maybe I need to invest in 4S packs...?

But even still, out of the gate this is flying well. It's running stock 4.1.1, with a few tweaks for smaller frames, and seems to be behaving itself. It's quick, stable, agile, not quite as snappy as I would like, but I am getting 3 minutes from a 350mAh pack with those bigger motors, despite the extra weight.

Plus it's still teeny, tiny but is recording HD video like a grown up quad. I'm actually pretty chuffed with this one.

Nice detail work,. I Guess I will be de soldering my motors now thanks to you and adding shrink over the wires about the arms. Seriously nice deail work.
I always shrink my receiver and VTX as well like you did. A little scared of AIO boards though. but very nice job sir.

Thank you so much! I like to try to keep builds tidy, not that it's always possible. But it is worth the effort.

And yes, with 4S and 65mm bi-blades this is a really great machine. It's flying like a much larger rig, and of course that AIO is recording 1080p, so you really are getting a lot of machine in a very small package. And so far the AIO is holding up its end of the bargain just fine; both flight and video are all perfectly acceptable!

Quite impressive. How much does it weigh? Before trying 4S batteries I'd try a higher pitched prop though, like the Emax Avan Rush?

Thank you. It weighs 83g, which is a bit chunky for such a small machine, but given what it does, I'm ok with that. In the end, I did both. I put on Gemfan 2540 triblades, which were good but ate my battery, and so then put a 450mAh 4S battery on top (which looks a bit comically large in truth).

And it's a fine combo. 3-4m of solid acro flying, faster and with more snap, and the extra weight is actually a plus; it makes the handling feel a bit more like a full-sized quad, definitely easier to loose altitude. I am seeing more shake at high throttle, so some tuning is needed, but otherwise, I am pleased with where this now is.

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
