I'm finishing up a 1/3.65 SM Hawk, & would like to know if I order a 310n pipe, then decide to go with a K260 instead, could I still use my 310N pipe?
Thanks, Jay

I dont see why you can't, may have a little thrust loss but I doubt you would notice.

You will get a fairly large static thrust loss as the gasses slow filling the big pipe. Do you know the dia difference?

You will have a thrust loss but the 310 was too much power for the plane anyway, so you will be good. Enjoy!!!

I remember someone posted a Jet Cat pipe chart and the 220n to 300n was the same inlet and tube sizes... I don't think there is any differences.



Found it.. here you go

I am sure every manufacture will have different recommendation depend on there exhaust cone sizes. But the Jetcat chart is a good starting point

Thanks guys, IDK the diameters, but I currently have the smaller pipe, & would like to go ahead & order the bigger one, but may get the 260 instead of 310 if it's ready by the time I'm 100% ready

I had a pipe made for a 310 but it was not out yet so used a k210 with no issues or noticeable loss of thrust. I see no problem with it.

Thanks gunradd. On that note, I'm pretty sure that I'll just place my order. Maybe I'll try one of the new US pipe maker's pipes (I think they're made by Joey Tamez).

Just talked to Joey yesterday. He is making me a pipe for an F84 I'm building. Quick service and great looking pipes.
