I just want to know if there is aftermarket velocity stack's available for OS Surpass Engines. I know you can get them on Saito's. Anyone made one? I have seen a photo of one on a OS AX 46 here on RCU.

Yes, the new series of OS four strokes have velocity stacks and they fit the old engines

Thanks, seems if Tower does not sell them seperately

Here you are.

Thanks Greg, Velocity Stack - Air Funnel (Potato-Potaaato)

Here is one I made for my .52 from the stem on a Hobbico SuperStarter.

Hobbsy, what do you use to make it "stick" to the carb
