Guys,
More info.
Currently, AMA 424 and RCPRO Club 40 Silver use the EVO .46nx. Silver also uses .40s, mostly TT. RCPRO Club 40 Gold uses .46s. Those classes are currently flown at the Nats.
Last summer, Silver was .40s only, mostly TT. After the winners were are determined in each class, we ran an extra heat with the top two in Gold and Silver. It was Silver, Silver, Gold and Gold.
You all may want to get together.
