If OS charged a more reasonable price, the. They would be a more viable option. IMHO, Nova makes a nice engine and they provide a substantial value for your money considering they're cheaper than the SH/LRP variants and are better made. I haven't had any problems with any of my SH variant engines in nearly 20 years, nor have I had any problems with my Traxxas engines... That's not to say there's been some lemons though! They have all tuned great and run great. However after running a Picco P3 over he last couple weeks, I'll never a buy another SH engine as long as Novas are that much cheaper. This Picco is a BEAST and makes HEAPS more power than my SH .28P6. There is no comparison - The Italians know how to make a fine engine.
