Hobbyking recently released the new Quanum Elite VTX. We looked into the features and spec of this video transmitter, and discussed what the pros and cons are.

Features and Specification
The VTX comes in a nice cardboard box, with a manual, whip antenna and a silicon signal/power cable. There are 25mW, 200mW and 600mW versions you can choose from (indicated on the manual as well).
The VTX comes in a silver aluminium case, and two tabs of mounting holes. There arevertical and horizontal antenna connector configurations for different mounting requirement. (I imagine the 90 degree version would be good for FPV planes)
Note that the location of the tabs on the two different version are slightly different.
They all have SMA antenna connectors.
They take 7V to 20V input power (2S, 3S, 4S), and outputs 5V so you can use it to power your FPV camera if needed.
Another good feature is the support of Race band, which is 37MHz apart from the next channel, all 8 sub-channels in Race Band have little interference with each other, this is great for FPV racing.
The metal case not only protects your VTX from fatal crashes, it also acts as a shielding blocking unwanted frequency noise. Heating has always been a problem to some VTX, and the aluminium case is a giant heatsink that helps lowering the temperature.
Frequency bands and channels can be changed by pressing a single button. You can see what channel and band you are on from the LED lights (blue is band, red is channel).
The aluminium case is heavy. The weight of the VTX is about 13.5g, and the case alone is 6.7g nearly half of the weight of the VTX.
It has mounting holes can be used to secure your VTX, but it might also cause mounting troubles in some cases.
It’s interesting to know that this VTX looks largely similar to the RMRC Cricket VTX, and the FX X50 from Banggood.
Here is the manual for future reference.
I have four of these now, one was ran over by a car the other shorted out (my fault). Ive found that interference can be caused by mechanical vibration. So I opened the case and put a piece of sponge either side of the vtx. Problem solved.
Any idea what type of plug that is. I’ve always liked to have a few extras on hand, just in case.
