I guess a simple "thank you" is all it takes, even I had thought that because this hobby can get pricey, the person/driver may appreciate something "extra" for his nice gesture. I have an O.S. 40 engine without a plane, misc equipment including an Airtronics radio. I have some tools here in Edmonton & some equipment at my sister's place in Calgary Ab. I lived in Calgary for a long time & when I got involved in r/c my hobby shop suggested the Sig LT-40 trainer. I skipped this step & went straight to helis. I wasn't a very good pilot. My parents moved from an acreage into the city, so I lost my "flying" spot. I'd like to get into model railroading as I can do that year round, yet with r/c aircraft is a seasonal thing in between time on a flight sim. I'm a guy without a car though & club airfields aren't next door like a Starbucks. I'll probably have to chose one hobby or the other but not both. The hobby shops here sell Great Planes aircraft.
Thanks
