Picco 67-80 engine OPS 5780 Open nitro pipe @ 11 3/8 - 11 1/4 60 Nitro. VAC 91 Engine? I prefer the MAC13cc open nitro pipe & the RS101 I prefer the MAc 15cc open nitro pipe. Picco 45? MAC`s 7.5 pipe or CMDI Parobolic pipe. Nova Rossi .21? MAC 3280 3 1/2 plug to band. B)

Remember if you run in hot weather or High Corrected air you will need to add length or volume of pipe..... Very different than the days you ran & the air quality is good to excellent.

Here is some info on tuned pipes, if anyone is interested.

John, I think Joe may have answered your question. "Remember if you run in hot weather or High Corrected air you will need to add length or volume of pipe..... Very different than the days you ran & the air quality is good to excellent."

Here is some more info., if you need it.

 

[Joe Warren]

Pipe designs,& length are the single one thing that can get a boat to perform excellent. After you have found you pipe of choice, You can began to pitch the prop for max speed.There is no single book on all of the variables of R/C boat tuning. it is Boat set up (mfger), Spec Pipe 9Boat mfger), Spec prop for the engine & a lot of pond time........

 

[Al Hobbs]

I agree Joe. Depending on your boat and set up a pipe that works well for other people might not work well for you.

The answer is time at the pond.

Yes Rick on the cut down header pipe but I didnt try the other pipe with the longer pipe because I I barrowed it that one day and it took a week to get the new one from Stu and when it ran the same I didnt think to try the other pipe to see if it worked. Charles
