Introducing the Armattan Tadpole DJI 3 inch Main and LiPo Plate conversion kit. Featuring a 3mm main plate designed for a 20x20 flight controller with 12mm motor mount pattern for 4s-6s 1505, 1606 and 1808 motors (crazy fast and agile).

This is HUGE! You can now mount the Caddx Polar and use BetaFPV 1505 motors with 12mm motor mount pattern on the Tadpole

DronerFPV designed with Armattan Productions to replace the existing Armattan Tadpole 3 inch 2mm 16x16 FC main plate and feel more like a 5-inch freestyle frame with more agility, zippiness and flight time. The LIPO plate sits taller with the use of 2-20mm standoffs on the back to allow for the addition of the Caddx Vista or Caddx Polar with plenty of room and is also longer to hold 650mAh batteries. You can also add 1.5mm standoffs in front to increase the height with the existing camera bracket or even use the new Tadpole HD camera bracket.

The added stability with the 3mm frame, 1505, 1606 to 1808 motors and larger 4s-6s 650mAh battery size make it perfect for carrying the extra weight of a Naked GoPro, SMO4K or Insta360 GO2 or GO to capture your freestyle footage in HD, coupled with recording with DJI Goggles.

very nice, can you guide me to make one like this ?

DronerFPV   Aug 26, 2021 

Happy to help if I can. What type of questions do you have to start? Also, I need to get these 3D prints on thingiverse, which would be helpful I'm sure!

beautiful build!
what the weight of the frame including the convertion kit? what is the overall weight?

DronerFPV   Aug 26, 2021 

I'll have to start including a pic of the the frame and build on a scale showing weight. I'll try to go back and do this as time permits and start with this one. Thanks for asking!

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..
