Awesome flying, Keith! Thanks for the update! 😃
It's great to see you back!
Stay safe there with your family! 🖖😊
Good to see you back it would be nice to have a fan on a switch until after the transition the vtx was getting hot
Yeah with the full nose that I have on here right now it tends to heat up while waiting for the GPS, then hovering after takeoff. It cools right down with some forward airspeed though. It just needs some airflow while stationary. A small fan would certainly help.
Excellent. Thank you.
Thanks for watching!
Looks. Good. Hopefully, i get mine soon. I've been trying to work out air shipping with haohan. By sea takes way too long. From what i can see its probably missing faltering in the pids.
Using the tilt for yaw control, eliminates the yaw instability inherent with the regular tri-copter layout, and also means it will yaw at the same rate to either direction, rather then the slower yaw when turning against two props, and faster yaw turning against one prop.
Does it park the rear prop inline with the body, or with the wings? I imagine the latter would cause more drag.
Nice video Keith! I'm jealous of your better weather, I need to try and get some more flights done with mine but it's been too stormy.
I'm really quite enjoying it though, in VTOL format it answers the main drawbacks of the standard version.
You have to admit though, your low ceiling and the mist was prettier to look at than boring empty fields... lol I'm looking forward to seeing what we can get out of these with more tuning, and you're right, it addresses everything I didn't like about the standard fixed wing variant.
Great vid. I have a T1 Ranger vTol, and I have found that Amp draw in transition and at landing is huge and flight times low for the type. Just saying in case anyones considering a vTol, these are the tradeoffs so I have found. It stopped me using Li Ion batts as they struggled with the draw.
In terms of amp draw, would you say it's comparable to a multirotor, or is it worse? I've got no experience with VTOL planes, but lots with quadcopters.
Edit: I saw in the video. That thing is terribly hungry! Even my big quad doesn't suck power like that, and it's not light in the slightest. On 6S, it's like 10-15 amps to hover, and 20-25 to cruise. All I can figure is that the small props have a rough time.
I came to the conclusion that a 7" quad setup for efficiency would be better if you need vTol and are not going to travel more than 8km away.
For the FireFly VTOL, if it is operated using multicopter mode only for takeoff and landing, and fixed-wing mode for cruising, with our official full-pole 2P battery, the actual tested endurance can reach 80 minutes, which is far beyond what a typical multicopter can achieve.
Nice video, the Firefly and the vtol still have the same big problem with a crosswind or head on with a gimbal in it. The surface area on the sides is huge and the nose cone works like a scoop and slows it down as you would know but apart from that it flys well. It’s a shame they didn’t send you a full version seeing the kit is not going to be available.
Another great video..
Wow.
Great video! Looks very stable! Where did you get that Ardupilot sticker? Looks great!
Thanks! A guy in one of the AP groups was making them and selling them on Etsy. They're still listed here www.etsy.com/listing/1672927182/
The standard tune seems to wrk - not perfect, but it works
Yep, it works well enough now, but I know it can be closer to perfect with a bit more tuning. lol
What vtx and osd mix are you using?
The VTX/camera is the "Walksnail Avatar HD Nano Kit V3" (caddxfpv.com/products/walksnail-avatar-hd-nano-kit-v3??aff=59) and the font is "Clash" from Sneaky FPV. sites.google.com/view/sneaky-fpv/home
@bonafidepirate thx
if the motors stopped in hover condition, would the aircraft glide?
Assuming you start with enough altitude to build airspeed it will stabilize and start flying.
Does anyone know what happened to Haohan and their Firefly rep. Eddie? They appear to have gone Missing In Action since December and still have many outstanding paid orders still pending to be filled. The lights seem to have gone out and nobody is answering the phone or emails. Smells bad.
I just saw Haohan replied to a similar message on Facebook, so I thought it would be worth relaying here:
...During the Chinese New Year, everyone takes a week off before the holiday to return home; otherwise, it's almost impossible to get train tickets. Regarding the package to the USA, since we set its value at 560 HKD, it can only be shipped via sea freight to keep the shipping costs manageable, and we need to send it in batches. I'm really sorry for not being able to reply to your Facebook messages promptly while I was back home. Please rest assured that we are absolutely trustworthy. Before our holiday, we managed to send out goods to countries like Singapore and other farther destinations! Currently, communicating via email is the most convenient way for me while I'm back home. Crunkle informed me about these issues, and I sincerely apologize for any inconvenience caused. We plan to ship your order during the first week of February when we return to work. If you could patiently wait until then, I would greatly appreciate it. Sorry again for all the trouble！
@@bonafidepirate Thank you. I have since heard from Eddie although I can't say his response was very comforting. Anyways, Excellent video! I loved the OSD Font, layout and graphics. It appears you may have used the SNEAKY_FPV OSD Tool. I'm just becoming familiar with it after recently watching a Painless360 video. I assume that was an antenna tracker by the shed on the tracker. I'd like to find out more about it. I do have a question about your RSSI. Given an indication of 100 is the best and 0 means you are off in the land of Oz, at what point is your threshold to proceed no further and turn around? I enjoy your videos and appreciate the due diligence you do for the hobby.
Great videos thank you! But IMHO it’s butt ugly
