General XLPower 550/Nimbus?

[D.O.G.]

I have the XLPower 550 and I notice that the XLPower 550 Nimbus has a 650 stretch kit. I wasn't able to find the diameter of the tail boom but I was wondering if I can use that Nimbus 650 stretch kit on my plain XLPower 550?

Yeah, I did some searching and doesn't work, but I thank you for your help.
