i have no idea on my next frame. i only can tell you, that i have the listed parts and that i want to use existing lipo batteries.
i'm not going to joyn any race, just freestyle only. i prefer a top-mounted battery mini/micro quad.

please keep in mind, that i only have this 16x16 stack (ESC bottom/FC on top) so no 20x20 frames.
maybe, someone knows other/better props for the t-motor mt1306 with it's M4 shaft!? so i'm free to go 2,5" or 4" !?

please leave any suggestions, and please remember that i only can order from:

  • ebay
  • amazon
  • banggood
  • gearbest
  • aliexpress
  • or any german or at least european distributor.

after some struggling with the first flight stack and all the motors lying around, i've bought another flight stack (20x20) and now everything works fine.

hope my iRC ghost kit will arrive soon, so this build will be my first long range one.

update I: i was on of the first who pre-ordered the ghost kit and still don't have it.

update II: new motors coming in, they're from geprc (gr1204 5000kV). than there will be another prop set from gemfan, the windancer 3028-3 yellow.

update III: new props, the emax avan mini 3024 and the new LiPos from GNB (3s 520 mAh HV) are tested in this video below.

update III: the caddx ant is now replaced by the caddx tarsier 4k, for which this frame was initially created around. so the weight is increased by about 18.1g, which you can feel instantly. we will see, how it has impact on flight times.

You may have a rather light power setup for it, but the 3inch micro reverb ( is rather appealing. I am planning a build for it at the moment. . .

This frame has mounting holes for 20x20 stacks, but I need 16x16

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..
