ratshooter, I understand, my H-9 Cub sat in the box under the bench for 2 yrs gaining seniority (collecting parts and accessories) while other projects were completed. We have had some nice weather here in west Georgia (we are about to go back to rain for a few days) so I got to fly some yesterday and today. Today was my recently completed Saito powered H-9 Cub's turn to spread it wings. Sweet flyer! Your OS 70 four stroke power will be "just right" when you get to it. Good buy on the $75 Aerosport too! Sunshine and tailwinds to ya.
