I've found A small picture of the xenon kit, and it looks like it uses an AE style front end, and not the front end I showed before.
So I guess you're right about that it's A homemade front end, based on the ideas of the CEFX and Corally.
The wishbones aren't made out of T-bars, because they're too wide for it, though it looks like it's made out of the same material.
It's very difficult to find spare parts for the Hara kit, some even buy more kits just for the spares, so finding hop-ups will be even harder to find.
I don't know what the use of that second cap (first is just on the esc) is.
It looks like it's hanging on the reciever, maybe it's something different than A cap?
