I can usually build a Lt-40 kit in a weekend then another one to cover it... my daughters Lt-40 was built in a weekend flown the following weekend with a TT-46, then last fall I pulled the TT out and converted it to electric.
I haven't built an LT-40 but have an LT-25 and like you found the build to be very quick.
However, out of respect for the OP, he asked about an arf.
