Hello Peter,

sorry for the late reply, but the message you sent me was well hidden

I'm afraid I know nothing about Sirio .21 but what I hear from others. the 2013, which is banned in Europe due to noise, is the best.

I guess the best alternative would be, as always, the NR 2015.

thanks Stefan, i meant to send pm but for some reason it went to profile page which most people don't visit to often, i will be running master class at winternats, yeah finally got old!! my girls are now 21 and 18 just traded all my rc stuff for an arsenial of guns lol! hope to see you again some day take care Peter
