Hornet front arm upgrade....I.D.

[pengoo]

Seen a few hornets now with upgrades etc ...I wanted to build one off with nice upgrades ...I purchased the aluminium front arms and center fitting .but find it rubs on each other unless I file it down ..So now found 2 models built over in Japan ..with a arm I don't know what it's off ...(hot shot ) I was thinking but wanted to ask you guys ..I have also seen grasshopper 2 arms in place .but these square arms look so much better...
