Blueyonder... I have about 1.5 gallon through my Tiger 3 now and have to say it flys exactly like the Carl Goldberg Tiger I built from a kit. The only bad thing I can say about the Phoenix version is that the firewall is quite soft and you need to add a layer or harder wood or fiberglass it first. My engine mount kept embedding into the wood they used so the screws were always loose. Also... The landing gear has to be bend back about 30 degrees just like the Goldberg Tiger if you fly with the CG at 38 % like I do. (That CG really helps slow approach speeds and it allows good snap rolls too!)
It is definitely worth getting and a lot of fun to fly. Fire away with any questions and I will be happy to give my an answer.
