Why do you want one of these horrid things John? Set up correctly, they start ok, my 13 yr old, many years ago, was hand starting his, if it’s a big radial cowl, or a skinny undercarriage, much prefer a Tony Clarke booster,
Thanks for your response. Recently bought a 1/4 scale Spitfire which has one fitted and liked it. I’ve since bought a Hornet with 2x62 Zenoahs and wanted to do the same!
