I have the Brillelli 26SSR, it will hover my 11.5 lb yak with marginal pull-out. I am running an APC 17X8 turning 9200 rpm. It will easily yank your 140 pattern plane around, especially if you are only flying IMAC style maneuvers.
Scott is a great person to deal with. If you go that route I would call him before you order to get an estimate on how long it will take to ship, he gets a little backed up from time to time.
