Thanks, John. It was a lot of 'work', every free moment over about 5 weeks, but I loved every one or those moments. It's not work at all, I get obsessed. When you do start yours do a lot of test fitting of the fuselage halves. I found that the bulkheads fore and aft of the cockpit are just too big and need to be filed down massively. You can just leave out the radio compartment bulkhead. Similarly, the crankcase tube that the cylinder and push rod rings slide onto is simply too large and that also has to be filed way down. Many other parts require sometimes radical "customization" to go together properly. Never blithely put glue on a piece and assume it's going to fit - as with a Tamiya kit, for example. Even the clear wingtip running light covers are bizarrely way off. I'm wondering if maybe that's why this otherwise fantastic kit (sooo much work obviously went into producing it) is no longer sold? Oh, and install the tail wheel when putting the fuselage halves together early on, don't wait until the end as suggested as an option in the directions, there's a lot of carving and modifying needed to get the strut to fit right in there that need to be done while there is still access to the tail wheel bulkhead. These things are the "despite its challenges" part of the topic title.
