I am also building an aquastar and am a beginner r/c flyer. I already have my engine pylon built can I shim the front engin mount screws to give some upthrust? I was also wondering about going to a t tail for more elevator authority? I did see one person that did that but seems like lots of others have been able to row with the stock conversion. I am going to run the .061 wasp, anyone ever run one of these? It recommends no synthetic on break in but I havent had good luck finding any without synthetic. I did add the chines as ACER did on this sight. Any other recommedations would be helpful thanks!! Happy flying. Clint
