been doing a lot more racing and have had my 4s packs all start to fall over.. so i bit the bullet and built a proper 6s low kv version of my raptor racing rig to replace the 2600kv version i killed racing a few weeks ago..
while my 2150kv 6s version is a blast to fly its way to fast for my level of racing hence this guy
i actually have a pretty major update coming to the airframe in the way of an alloy mid plate but i got an interesting message from my machinist today.. he's keen to cut the new mid plate out of magnesium which is 33% lighter than alloy and just as strong.. i don't think amy ones produced a racing frame using magnesium yet so it will be interesting.. will build 2 identical birds to test the mag alloy vs the carbon mid plate.. should be interesting as I'm not sure what the resonance properties are like

How do you like those Gemfans? I just bought some to give them a try.

i really like them. they are not fast at all but they are really smooth and have great response and control.. perect for racing when your a bit slow like me ;D

Awesome! I heard they can explode during flight. Ever had that happen?

looking good, that build looks nice. About to put together my 20x20 with the AIkon ak32pin and the talon f7. Let me know how that magnesium plate holds up. Also how much does the frame weigh?

the Skonk   Dec 13, 2018 

with the pod and all hardware 65g. the magnesium mid plate will be 2.5g lgihter than the alloy verion so about the same as carbon. i'tll have no pressnuts and 10mm bolts not 12mm bolts so i expcet it to be around 5g lighter over all

Nice every gram counts these days.

totaly.. i just got a couple of packs in... she flys really nice.. these motors are very smooth

Personally I would worry about magnesium, on the off chance you start a lipo fire (rare these days) and you catch the magnesium on fire, you will not be able to put it out. Safety first!

the actual iignition point is very high.. and the battery has arms and a carbon battery plate between it and the mid plate.. i really doubt you could get it going to be honest

You've probably heard the term "Cinewhoop". Traditionally it's a 3" ducted quad capable of carrying a GoPro Hero7 Black at a low 10 degree angle. More recently the term "Cine" has been applied to a number of RTF quads ranging from 85mm to 3". They all focus on their HD capability, but none compare to the stabilization of Hypersmooth (only available on the Hero7 Black). This is what really offers that..

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
