hi folks,i myself purchased a phoenix model tucano.this is the first time i have researched results from fellow aviators using the web , i have to say i have never seen so many different results with so many deifferent 2 and 4 stroke setups.I chose this model due to its apparent performance,ie to become a replacement for my aging 40 size stick.if i have read thru correctly it seems to me that the magnum 52 2 stroke should give adequate performance.if anyone has tried this set up pls let me know how it came out and how badly the cowling will have to be mauled to make it fit.many thanks in advance. joe
