Always check over used purchases with the utmost scrutiny. I bought a Sig Kavalier almost flyable for $24 once. There was a lot of things wrong with it as I found out as I installed my gear. Most notably was the rodent nest a few inches away from the tail in the fuselage
. Said rodents breakfast was the balsa pushrods and they were down to almost nothing. Glad I didn't fly it without checking the old pushrods, or it would have been a goner!
