My first quad/build! Targeting a digital toothpick size and flight style with Quad 66's touring 122 frame. This may have been bold for a first FPV experience, but I have yet to break in and tune this quad, so we will see...
Notes:
- Motors are the 5500kv 1303.5
- Props do need hardware (not shown in cover image) since they are 1.5mm shaft motors
- About 73g without battery and 104g with 550mah 2s batteries
- The through holes on the frame under the motors are slightly small so be careful when sourcing motors as large e-clips on the bottom will be an issue.

Where can I see a video of the assembly and flight of this model?
I'm interested in copying this build but I'm concerned that its a unibody. I feel like I would prefer if it had detachable arms in case I crash badly and break one. Do you have any thoughts on this? I'm a novice and I've never built a quad before but I have the Whoop Lite and Nano 90 so this seems like the perfect build to copy. I just dont know about a unibody frame....
Toothpicks are surprisingly resilient since their weight is pretty low. I would say that this one is still not really heavy enough to cause too much damage unless you are flying it full throttle into concrete. However I have been flying very conservatively since this is my first build, and haven't really crashed into anything like that yet.
I do have a word of warning about the frame: make sure to tighten and fasten the screws that hold the canopy to the x frame. This is going to sound obvious, but I zip tied my vtx antenna to the canopy and snapped the canopy on without tightening the screws. In a crash, the canopy detached and ripped the UFL off of the vtx pcb.
Very nice build. I have one similar in two inch. I was wondering, I thought of building a 3 inch version like yours but using the fullsize Avatar pro-vtx and micro avatar cam. From your flight perfomance, do you think your build could support that? Also have you tried 1202.5s? That might help with your amp issues although mounting holes might be smaller.
That might be on the heavier side for this build, and might max out the FC stack height on the touring frame, but it could be possible. If you are going to try it, I might aim for a 3s just for a more enjoyable flight time.
As for the 1202.5 motors, I am not opposed to trying them out, but that will probably come after a board change. I have been having issues with the Darwin board losing TX and Gyro after very minor crashes.
Are you getting any of the canopy in view with that camera? Also, how is the clearance between the camera and the stack? I'm wondering if the canopy works for walksnail or if I need to do a dedicated one for walksnail?
I am getting a little of the canopy in view at 16:9 and uncropped 4:3. At 4:3 Full there is no canopy in frame.
As for clearance, I have about 1 mm to 1.5mm between the camera cable and the top edge of the VTX when fully assembled which seems reasonable to me. If I were using a walksnail camera with a rear housing, this clearance might be an issue. I have uploaded an image to the build that shows the side view of the clearance as best as I could.
Also note, the VTX is mounted really high above the AIO due to the annoying orientation of the usb port. I am sure stack height varies based on how integrated your flight controller is, but just a consideration.
Awesome build!
I'm building my own any day now
Its 3D printed and included in the build links above.
I thought it was cool looking and it works well, but does require some additional tiny mounting hardware to fasten to the walksnail 1s lite camera. The M2 frame mounting hardware may also strip the holes in the print at some point, so you might want to print a few of them.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
