LOWE STC vs the 'Other Ones'
Usually when someone sees a Lowe Conversion, the first words out of their mouth are, 'It's so Cute', then they say, 'Oh, a Texas Taildragger!'. If they say that, they don't know what they are talking about. This is NOT a TEXAS TAILDRAGGER! Nor is it the Bush Tailwheel Conversion. Both of those are taildragger conversions, but they both use the original Cessna 150 gear and just move it forward. Then they install a tailwheel spring on the underside of the tailcone. The result is a prop that has about 7" more ground clearance and a tail that sits a little lower. The Texas Taildragger and Bush Conversions can be used on all Cessna 150s and 152s.
The Lowe Conversion uses Cessna 120/140 or 140A gear and bulkeads AND the Cessna 120/140/140A tailwheel bracket and can only be used on the 1959 - 1963 150s. Since the 140A fuselage is essentially the same as the early 150 fuselage, it is an easy fit.
The 'Other Conversions' use the existing main gear, so you don't have the expense of finding another set of gear, whereas the Lowe Conversion uses all 140 parts, but they are readily available.
