Armattan Gecko DJI Ultralight 4 inch - Caddx Polar - New 3mm Frame - 6s Madness
By DronerFPV on Aug 08, 2021
DronerFPV designed with Armattan Productions to replace the existing Armattan Gecko 4 inch main plate with a ultralight weight frame and LiPo plate to feel more like a toothpick or 5-inch freestyle frame with more agility, zippiness and flight time.
The lighter weight 3mm frame allows you to mount the lighter weight 1.5mm shaft motors like 1505, 1606, 1805, or 2004 motors coupled with a longer LiPo plate makes it perfect for carrying a lightweigth HD camera, like the Insta360 GO, Insta360 GO2, BetaFPV SMO4K, GEPRC GoPro 8 or Naked GoPro to capture your freestyle footage in HD.

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..

Looks like it handles freaking awesome.. I have been thinking about building a 4 inch 6s rig. I actually am building a 2fiddy 4 inch right now, and debating what motors I want to use. How do you feel those 1700kv 2004's were?? Did it struggle pulling out of dives at all? I have some Tmotor 2004 3000kv (1.5mm T mount) and Xnova 1804 2400kv (they are regular 5mm shaft) I have a 2fiddy 5" on NBD flow 2004 1750kv, and they're perfect on a 5" prop on 6s. Really curious how those were on a 4" prop. Amazing flying spot too.. super jealous lol..
I like the BetaFPV 2004's but one problem is that they seem to rub the frame on the bottom of the motor. The clip is bigger then most other motors and needs an 8mm diameter. You can see in my design, I had to 3D print some spacers. I just ordered some Tmotor 2004 1700kv and 3000kv which seem to not have the same problem. I would try the Tmotor first, since you have some. Let me know how your build goes, would be interested to hear about it!
And the spot is awesome! thanks!
Ah man, I get that problem every now and then, and have a pretty quick fix. I just take either a wood working countersink bit (that drills a V shape into a drilled hole.) or a carbide burr in the shape of a cone or rounded, and just countersink the hole on the motor side of the arm. It usually doesn't take very much, just to get clearance for a C clip or a screw head. Or a small round file works in a pinch. I'm sure you already thought of it, but in case you didn't, it works great! And I will let you know how it goes. I think I'm going to go with the Tmotor 2004-3000kv, and motor limit it down to take 6s. One thing I love is the 4" platform. I love light 5" too, but the 4" have less float and more throw IMO, because of the high power punch combined with less active braking on the smaller prop. Ooh I gotta get back into my build! I'll try and get some DVR from a local golf course too lol. Thank you for the reply!!
Thanks for the advice! Will try it out and look foward to seeing some DVR of your build!
