EDIT: GEPRC have renamed the original Phantom as the SMART25 to align with their other "SMART" lines of quads.

I've been meaning to build a micro/toothpick type quad for a while but seeing as I haven't even been able to get my arse into gear and finish the outstanding repairs on my Trashcan, or actually finish building the Acrobrat that I bought all the parts for almost 9 months ago, I decided to just buy an already built BNF micro quad in the Banggood 13th anniversary sale.

Off the back of AndyRC's trusted review, the GEPRC Phantom is the one I decided to pull the trigger on over all of the others (HERE). I got the one with the XM+ receiver included so I can just bind it and go without to much messing around (although I'll first need to flash EU-LBT firmware to it so it matched my X9D+). It's not the fastest of the toothpick style quads but I like the fact that it uses a 16x16 stack instead of an AIO whoop style FC, and I like that it uses a proper carbon fibre centre body construction. It sort of reminds me of a baby version of my Martian II Smile

The one thing I will be changing almost immediately tnough is the Caddx EOS2 camera though because it's quite a poor camera with it's over-saturation of the red spectrum, so I've pushed the boat out and also ordered a RunCam Racer Nano for it. I'm probably also going to stick on an omni-directional VTX antenna for better range.

I love flying my 5" but I'm really looking forward to trying out these toothpick style quads. If I'm lucky I may even get to fly it in the park that I used to fly my 5" at before I got ousted as a nuisance and noise polluter. I guess we shall see.

I know that Oscar has done a review on the Phantom (HERE), but below is AndyRC's glowing review for anyone interested. I'll let you know what I think of it once I've had a chance to fly it. It should be with me in a couple of weeks.

The GEPRC Phantom is supplied from the factory with Betaflight 3.5.7 installed. Below is a CLI "diff" of the original untouched GEPRC Phantom configuration as it was supplied with from the factory...

I'm really interested in hearing what you think about this once you get some packs in on it. I haven't flown in a while and have been spending some time on the Sims to get my flying chops back up to snuff.

A slower toothpick in an open space is probably the way for me to go for a bit........ Big Grin

Oscar · 14-Sep-2019, 09:29 PM

Honestly i'd choose the Sailfly over this one for value and top speed Smile

Rugaru · 14-Sep-2019, 09:49 PM

I've been eyeballing the HM Larva X.

Have either of you had a chance to fly it?

SnowLeopardFPV

HappyModel are still using the Crazybee F4 AIO boards in their models which is a bad move IMO and I've already experienced the voltage regulator failure they are susceptible to with my Trashcan. I think they may have partly resolved the issue with the release of the V3 boards but the Sailfly-X still seems to come with the V2.x board for whatever reason. Albert Kim also complained that the Sailfly has durability issues with both the frame and the motors which are apparently a common failure point. I guess it depends how you fly it and where. So I decided to steer clear of the Sailfly for all of the aforementioned reasons. I don't really care for raw top speed as long as the speed is reasonable, and the 16x16 stacks seem to be a lot more reliable than the whoop style AIO boards.

The Larva-X also uses a Crazybee FC, although it is one of the V3 boards.

Oscar · 14-Sep-2019, 11:36 PM

Maybe i am lucky getting the Sailfly late, and the capacitor fix is working well (or they did some change to the FC who knows), it's been very reliable for me over 50-60 flights and a few others i know.

Geprc phantom is the way to go.

SnowLeopardFPV

Well it took a while to arrive but my GEPRC Phantom finally got delivered yesterday. Before I take it on a maiden, I need to flash the XM+ receiver with EU-LBT RSSI firmware and I also need to fit a buzzer, because if I don't then it will be just my luck that I end up losing it in some undergrowth on it's first outing. It did come with ESC buzzers enabled but those are pretty useless in my experience so it will be getting a proper buzzer. I did think about putting a Crossfire Nano receiver in it but I think I'll just stick with the XM+ for now and see how it goes.

Interestingly it has Betaflight 3.5.7 loaded onto it, so I guess they were may have been able to better tune that version on such a tiny quad than Betaflight 4.x.

Even from pictures and videos online, you don't realise how tiny these toothpicks are until you actually hold one in your hand.

And a size comparison with my 5" Martian II. The Phantom almost looks like a baby Martian Big Grin

ph2t · 05-Oct-2019, 04:45 AM

Great to see you have now got a toothpick style quad now snow. I have found the sheer accessibility to fly with a toothpick - easy on the ears, public and dogs - gave me more time to practice than having the 5 inch tear up the skies and can be heard miles away.

Early BF 4.x versions are horrible for this class of quad, you really need to turn down the PIDs by at least 30% of their stock values before you can even think about flying it. The power to weight in this class is very high and BF 4.x (early BF4 at the very least) just created pocket rockets that would take off to the moon when armed. I use 3.5.7 on all my small class quads and out of the box on stock PIDS they are way more stable. Things may of changed with the latest version of BF 4.1.

It pays to check out the GitHub docs on BF4.x if you're going to flash it with that. Although I'm pretty sure you already know this. Big Grin

I have found that turning up the beacon and motor sounds values in BLHELI_S configurator makes for some loud, chirpy motors, this helps when space is at a premium and one doesn't have a buzzer installed.

cheers,
ph2t.

Yes, I'm going to try and take this little thing back to the park that I and my 5" got kicked from and see if any dog walkers start trying to kick up a fuss about it. While I love the "baby Alien" style of the frame, the downside is that it does have some angular edges so it doesn't look quite as soft and harmless as some of the other toothpicks with their flexible TPU canopies. I'll guess I'll find out what reception it gets if the weather ever stops being so miserable.

The Phantom was released after Betaflight 4.x was officially released so there must be a reason that GEPRC didn't opt to use Betaflight 4.x for it. It's probably as you said, that BF 3.5.7 is just kinder for these small class quads. I never really dabbled in the tuning aspects of Betaflight and have been spoiled in that on my 5", the stock out-of-the-box tuning just seems to work fine for my mediocre piloting skills so I've never needed to mess around with any PID settings. I'm therefore just going to leave the Phantom on Betaflight 3.5.7 and hope that the factory tuning that GEPRC already did will work fine without me needing to change anything. If I was to move to BF 4.x then I would most likely have to start trying to change all the PIDs which I don't really want to get into unless I have to. I guess I'll just have to try and try and get over my OCD that this quad isn't on the latest greatest version of Betaflight Big Grin

I have the real estate in this frame to fit a buzzer which is one of the advantages of this style of frame so I'm happy to sacrifice a few extra grams of weight for the sake of a proper buzzer that you can hear a mile off.

SnowLeopardFPV · 05-Oct-2019, 05:24 PM

A FullSpeed Lucky Box Buzzer is now all fitted to my Phantom and is working a treat. I could have probably just used a regular buzzer, but this is the smallest self-powered buzzer on the market and only weighs in at just over 2 grams so I decided that small weight gain was acceptable. It fits perfectly between the camera and the stack, stuck down with double sided sticky foam tape and then strapped down securely with two cable ties. In this location there is even easy access to get to the button on it with your finger. It's a 90dB buzzer so way louder than the beeping ESCs. Now I will feel safe actually flying this tiny thing out some distance from me knowing that I'll have a much better chance of finding it if it comes down Big Grin

The 16x16 stack is very nice and looks really well engineered with header pins running through the stack to connect each individual board together, so no hard soldered wires or wiring harnesses to contend with. And if anything breaks I can just replace the one affected board rather than the whole lot, so I'm glad they used a proper stack in this instead of one of those AIO boards.

[Image: CrrDAsA.jpg]

While I had the lid off I also flashed the XM+ with EU-LBT firmware which also broadcasts RSSI on channel 16. I was hoping to be able to do that with it still wired in by just attaching test clips to the exposed wires where they are soldered to the FC but unfortunately that turned out to be a fail because the 5V power from the Taranis fired up the 5V circuit on the FC resulting in a failed flash because the FC would have been trying to communicate with the XM+ over the white SBUS wire at the same time as the Taranis trying to flash data to it. So I had to temporarily desolder the red wire going from the XM+ to the FC. Then the firmware flashed successfully. A bit of a PITA but the XM+ hasn't had a new ACCST firmware update since 2017 so I don't think there are going to be any more updates to be applied any time soon (or ever).

Now all bound to my transmitter and appears to be working just fine from a control and auxiliary channel point of view. I've not been able to check the RSSI yet but hopefully it's all working. I guess I'll find out soon enough.

Your photos look like a product catalogue Smile

The stack is an awesome piece of kit and responsible for most of the $ figure the bnf attracts. I’m using it in my inv8r build and have found the shear lack of soldering required quite refreshing.

My only concern in the uf.l antenna connector. I’ve put s small glob of hot glue over mine and a small amount of the surrounding pcb just to keep it secure a bit more.

Happy flying mate!

SnowLeopardFPV · 07-Oct-2019, 12:51 AM

Some more catalogue pictures below Big Grin

The Foxeer Lollipop VTX antenna arrived so it is now fitted in place of the original dipole for a better video signal. Spare props also arrived so I they have now added some colour and a bit of a personal touch Smile

I also replaced the crappy nylon straps it came supplied with for some proper rubber coated straps.

The FullSpeed Buzzer, Foxeer Lolipop, and Straps added an extra 7 grams in weight on top of the factory build.

I'm also getting a nice clean picture through the goggles on the bench. Because the Caddx Turbo EOS2 cameras can be a bit hit and miss for picture quality, I actually bought a RunCam Racer Nano to replace the stock EOS2 camera with, but the picture I'm seeing though the goggles looks pretty good so I think I'll stick with the EOS2 camera for now and see how it performs out in the field. It it's acceptable then I'll just keep the RunCam Racer Nano for a different build.

I wanted to do a maiden flight this weekend but it was raining on Saturday and today was just way too windy. I know my 5" would have been able to handle the wind but I'm unsure about this little thing, so I need to take it out on a calm day first to get used to its capabilities. Hopefully the weather will be a bit kinder next weekend Smile

New Lollipop VTX antenna, coloured props, and straps fitted...

[Image: hwTQZUr.jpg]

And with a Tattu 75C 450mAh 2S LiPo attached...

[Image: 52UAPpg.jpg]

Weight without a LiPo attached is 66 grams (0.15 lbs), and AUW with LiPo attached is 95 grams (0.21 lbs). It's not particularly light by toothpick standards but I think (hope) it will still handle OK.

Yeah, I wasn't sure about using tri-blade props so I just stuck with the bi-blades for now. The ESCs are rated at 12A continuous current, so I'll see what sort of current they draw at thrust and then make a decision whether or not to risk sticking on some tri-blades Smile

I'm itching to get this thing in the air Big Grin
