Lightning RKH-66 2S
By TheLeprechaunPirate on Jan 06, 2018
This is my 2nd Rakon Heli Brushless tiny whoop build; but sporting 12000kv for some 2s power! The build wasn’t too tricky but soldering small is definitely a feat on its own. This version also sports a functional OSD.
Both my whoops fly amazingly well, and with the added power of 2s for Lightning; I get better outdoor performance.
In the future, I will be replacing the canopy.

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..

Looking good! Did you drill out those TBS x TW props? The packaging says there's a 1mm hub version but haven't seen on the market yet. I've built a whole bunch with that same frame and 0703/05 from different manufacturers and sadly, not too happy. Very inefficient. Good thing is that the smaller motors are coming that are testing well with 31mm props. Can't wait! Brushless Whoops are going to take off in 18 IMO.
Thanks! I did drill out the holes with a hand drill I bought from amazon, using around a .95mm drill bit. So far with all the props I have drilled into, I have never messed one up. But yes, I agree with the 0703/05 lineups... but I am managing almost 3 minutes on my 1s whoop with 450mah batteries, and a little over 2 minutes with a pair of 260mah on this guy... I can’t wait to try the 0603 or a new generation of these super tiny brushless motors.
I have a couple of hand drills in my cart and can't decide hahaha, can you please link the one you use? Also, do you drill all the way thru or do you stop at some point and, do you go straight to a .9 sized bit or start small and gradually work up? I'm probably over thinking this hahahaha.
Yea, tore both apart for the FC's before the 450 1S GNB's hit the market so never got to try, I really dislike the battery brackets on the RKH frame. I found some guy getting 5 minute flights with 0603/31mm props with the GNH, can't wait!
Thank you for the response!

I bought this one. I can’t remember if it comes with the right drill bit but it 95% sure it’s there. You don’t have to do any crazy steps, just center it onto the hole and drill it through. I just eyeballed all my drilling and never had an issue. I’m sure you have enough tiny whoop props to test them with!
Awesome! That was one found and saved in my cart for later. Looks like I'll be going with the same. Since it's a hand drill, does it spin when you put downward pressure? Thank you!
It spins when you turn it, it’s manual operated :)
Awesome, thank you Sir!
