TWIN NITRO RIGGERS ARE BACK!!!

[Piston1]

I pulled Andy`s full 67mm 1667 6.7 easily & have had 1667 6.9`s on the boat too. Dont under prop or the prop speed will be too much on the new P/L .014 on 60% Nitro & 20 percent oil...... The 14% oil is BS on the Big engines it will Kill the piston...... the ones that are running 14% are buying pistons too.....

Joe, who runs 14% oil in big engines?

I do, and had no problems what so ever. Done it for years.

depending on the quality of the oil.

I make my own fuel

Heres My Roadrunner Twin Nitro Rigger :lol:

 

[Tom Foley]

Julian , looks awesome ! I see the 80's have the "good " method of attachment for the carbs ! Here are a few photos of the new 91 install in the Twin formerly known as Don's LOL . You can see why I wanted to convert the carbs to rotary action so I could keep the clean Throttle linkage setup that Don did when he built this boat . I am ready to run now ..going to fuel her up shortly .

 

[Bill Gibson]

Don's handy work is truly off the charts OUTSTANDING!

 

[JeremyEdge]

Heres My Roadrunner Twin Nitro Rigger :lol:

Sweet.

 

[julianconde]

Yes Tom that exactly the carbs I have on mine but for 80 size but I will be using the bellcrank setup that came with the boat and the ball linkage setup on the carbs pretty much the same. The twin will be finished by friday and breaking it in this weekend. I'll be alone because James is going to Hagerstown and I'm staying back lol.

here an update on my Twin mitro rigger thanks for the pics now i know where to put the mixture valves james and i was thinking very hard on that one.. everything is installed we are now going over and make sure everything is perfect. Engines,Headers,Pipes,tanks,servos,switch (2 of them),props,shafts.. last thing is set the carbs,mixture valves,strut bushings and put the rudder bracket and rudder and its ready for the water..

Tom i need a pick from the hardware in the back I have issues. the rudder it had before was modified and i have the new one and the rudder bracket wont clear the rear right tail sponson :huh: so thats the only piece of the puzzle james and i have to figure outn and its ready for the water..
