Projet f4 retractable landing gear tires

[lvjet]

Does anyone know where to get replacment tires for the retractable landing gear for the nitroplanes f4? Im talking about the actual foam tires. Not the aluminum rims. On my first attempt to take off the tires turned inward on me and It wouldnt take off because of the low air speed. When I taxied back the tires were shredded. Buy the way, they say what a nice landing gear this is in the articles of nitroplanes, its not! the machining on this landing gear sucks! The tapped holes are all almost stripped right out of the box. $139.00 for crap. The Projet f4 E is also garbage. It looks nice but being a rc pilot for 25 years I can tell you buy experience, This is not a plane you want to invest in. Look at all the videos on U Tube and you will see not 1 good landing. All are disasterous crashes. Do not buy.
