Lightweight 4" 1407 3600KV.
Maiden flight 7/1/17. Flies beautifully! Plenty of low end power. Not enough room in my yard to let it rip. Motors were hot, but changing motor timing from medium to medium high seems to have fixed that. Was able to turn d_lowpass_type to PT1 without getting them hot again.
Overall impression: Totally stoked!
Build note: I had to add plastic nuts on top of the blue aluminum spacers to give enough room to fit the X6B receiver. This made less room at the top of the stack. I couldn't use padded double stick tape to hold the VTX to the top plate, but thin target brand double stick tape and a zip tie seem to be working well enough.
7/22/17 Got KingKong 4045 biblades, retiring DAL J4045 triblades. Motors come down much cooler. Had to reduce D gains right off the bat. All thanks to @bahb on that tip!

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..

On my Featherlight 4, I get away with DAL T4044, DAL TJ4045, and even HQ V1S 4x4.3x3 on BH 3600kV and RG 3200kV motors no problem, with no heat issues, with filtering off and stock BLHeli settings. It's odd to hear you're having heat issues, I wonder if the RG 3600kV are more prone to it than the BH...
In any case, 1407 4" is tons of fun, enjoy it!
