No taildragger experience here, so I guess that reduces the likelihood of a purchase significantly. I have been looking at a Lanier Stinger 40 ARF:
http://www2.towerhobbies.com/cgi-bin...?&I=LXSVE5&P=7 and using that for my .40 LA engine. There isn't much available for a friction bearing .40 sized engine, unfortunately, and I have two of them. So far, I see no parts availability or PDF manual for the Stinger. The model is so new that it's not even listed in RCUniverse. I'm hoping that will be fixed soon.
Regarding the Tango: I would still like to hear more from MMcConville about the possibility of transitioning to a fully symmetrical taildragger eventually, and which approach would be best.
