Hirobo Lepton and Trex 500 tail boom diameter

[HeliVador]

I am wanting to use the Microheli aluminum Horizontal fin holder listed for the Trex 500 on my Lepton, but I'm not sure if the OD of the two tail tubes are the same. Could someone answer this for me. Also I am replacing the Aluminum Boom braces with CF braces for more support. Has anyone else done this?


Thanks,
Brian

The outer diameter of the Trex 500 boom is bigger than the Leptons.

OD is 1mm bigger on the T500 compared with the lepton tail pipe
