Hey Hammer ! My little Sonic is a great flyer. I have a GMS .25 with a 9x6 prop in mine and it has plenty of ZIP ! I had a GMS.32 standing by just in case, but found it not necessary. I had to add a little weight to the nose to bring the GG in line but that was all.
It's a well built ARF and goes together fast. And good looking too ! Well worth the money !!
