I'm building a 7 in a ridiculously small space in my garden in London, UK. I'll be final assembling the aircraft at a pal's hangar and airfield about 100 miles away so need to get as much completed at home as possible. I remember seeing a dummy plastic Lycoming advertised but can't now find it. Being able to fit the cowling and all firewall forward gear using a light plastic dummy engine might be a real help. Anyone seen it? Also, if anyone has built an RV in a small garden shed, have they any construction tips to offer. Daft question, but you never know. Thanks in anticipation.
