I only recently learned of this frame. It looks like an EXACT clone of the ImpulseRC Apex 5 frame at ~1/3 of the cost. While I know that most people don't condone clone frames where it is taking money away from the original manufacturer, it's interesting to see the statement from Unmanned Tech as to why they are selling this clone frame. Unmanned Tech is probably the biggest FPV vendor in the UK and I can't help feeling that ImpulseRC have maybe somewhat shot themselves in the foot.

Unmanned Tech Wrote:Wait, is this an ImpulseRC Apex clone?

The short answer is basically yes. One day ImpulseRC stopped letting us order their products to us with little to no communication as to why. We tried to get more info, and then they stopped replying to us. So, due to demand, we’re almost forced into selling clone/”alternative” ImpulseRC frames. We have strong suspicions that for some reason, IRC have a deal with another UK dealer to cut us off as they don’t like that we sell frames below their price.In the future, we plan to release a blog post explaining this in more detail with some proof of our claims. In the mean time, you can satiate your coffin-frame thirst with these high quality alternatives!

If you want us to stock genuine ImpulseRC stuff, please ask them to get in touch with us and we will happily stop selling clone parts to replace with original impulseRC stuff.

I used to assume that had some kind of exclusivity clause with quadcopters.co.uk, but you can get ImpulseRC parts from Drone Is Life and HobbyRC, so who knows? They've had that notice on there since the Alien days, IIRC.
