RE: CMP 160 sized Texan
Hi Brad,
If my memory is right the YS is a higher performance 4 stroke thats made by O.S.
It might be slightly on the marginal side. You will probably have to forget about the retracts and go for the fixed wire LG from the kit.
You would need to keep it light but I'm afraid you will need to add some additional weight to balance it. Which will probably be heavy in the end anyway. It would be a good flyer with a 180 4S.
Good Luck, Doug
