nova prices are a bit higher than other brands..........

altough I don't see engines reaching the market and being recalled........
I don't see an engine version which is fast but at the 2nd fuel tank you can crack the crankshaft in two pieces.........
I don't see an engine being released on a website and taking 6 months to appear on the hobbyshop shelves.......
I don't see any Novarossi conrod being upgraded due to many problems......I also don't see any NO-nova based conrods lasting up to 10 hours of hard racing........

so IMO if you buy some brands you must be lucky to get no problems.......if you don't want to count on your luck than stick with nova.......
