Sig 4*40 ARF and OS FS-52 Surpass Ringed--------------------Good combo or should I use 46AX. Have the 2-stroke but have to purchase the 4-stroke. Which would be the best?

I know I will get good advise here.

Thanks in advance

The 46 probably will be stronger. If you want to use a four stroke try a OS 70 surpass or a Saito 82.

I really like the 46 engine, I personally love mine because of it's power.

Get a Saito 4 stroke on it...you will love how nice they run and sound. Good Luck Capt,n
