Hi guys,

I have a Saito 1.80 engine mounted on my Dynaflite Super Decathlon and i need help for this issues :

1.- The stock muffler its too short and leave my plane with a huge mess (the engine its mounted on its side). I bought from horizon hobby a flexible muffler (Saito brand) but the measures wasnt right ... i NEED some alternative muffler, tuned pipe, flexible muffler or wathever to extend the muffler and not take hours of cleaning up my plane after a day of flying. Im from southamerica so i need some item i can buy online.

2.- Im having problems with fuel feeding to the engine, i played with the tank position and it got better but not "too good" so im looking for a onboard pump i can use to feed the engine with good amount of fuel. Some people recommends oscilating pumps, but i dont know them and i dont know where to buy one ... any suggestion to this problem ?.

thanks

Pat

1) Try Slimline side mounted Pitts muffler. My 150 also leaves an oily mess, but most of the mess comes from the crankcase breather and not the muffler.

This is the correct Saito extension

The one with a muffler pressure tap is

The VP20 pump bolts to the back plate bolts on the back of the engine.

The fuel pressure is adjustable by turning the blue nut.

Enjoy,

Thanks guys but ... there isnt some onboard pump that NOT REQUIRES to drill the engine crank ?.

thanks,

Pat

I tried one of their flex mufflers and it broke apart after three minutes of engine run on the ground

Mhhh wow ... now im preocupied.

Another alternative its a Slimline Pitts Muffler, US$ 99 but im not sure if it will enough for messy oil throwing long from the fuse ...

The Perry VP 20 requires no drilling. It's a bolt-on design.

Enjoy,

Jim

You will have to live with the messy oil unless you fly a gas engine or YS four stroke. Having oil on the plane is as natural as a dog barking. It doesn't take much to clean it up.

Richard, i know but when the stock muffler its too short that almost dont protude outside the cowl, its a problem dont you think ?

I would try the Slimline Pitts muffler. The two muffler pipes are pretty long.
