Hi Roger

Nice boat and great place to play.My only suggestion would be change the prop nut for a smaller one as yours looks bigger than the prop hub so can cause some drag to your performance.

Hi Gill, thks , im waiting for a new flex chaft more longer to use a bullet termination nut, also im going test a rotary Novarossi carb, i think this older ST G20 carb dont have enough flow.

Valeu.

Roger, you are running pretty good, you might look at shortening that pipe length, looks pretty long. do you guy's use any nitro in your fuel?

 

[George Taylor]

Roger, email Glenn Quarles with [email protected] and he can help with the correct pipe length, agree with Rick, it looks way too long.

 

[RogerPro]

Hi fellows, thks, i apreciate very well your openion, the pipe is a MAC1120 from Macs with 11"lenght and im using Tornado Hely fuel with 30 per cent nitro, you sugest to cut the input of pipe or just tune the silicone join?

Regards

 

[David Murany]

60% nitro with 8" pipe length and you will here that motor sing.

 

[Rick Sowell]

cut the front of the pipe and measure the 8 inches from the glow plug around the header to the weld, or center of the fat part of the pipe. start there and let it rip.

 

[anthony_marquart]

also, this may sound crazy to you... but cut that cooling head to 3 maybe 4 fins. .21 motors need to run hot. you are cooling too much with that cooling head fully exposed to the wind and water. it is designed to be used under a car cowl, that is why so many fins. If you can get it.. run 60% nitro..

 

[George Taylor]

agree with Rick on the pipe, Glenn will tell you 3 1/2 inches from glow plug to the peak/fat part of the pipe, I'm running the same pipe on a 21 keep. Measure from the glow plug to fat part of pipe. I'll have to measure mine the way Rick indicated to see if it is the same.

too much cooling + too much pipe+ low nitro= no speed

If you can get 60% fuel you need to use boat fuel as there is more oil in it, car and heli fuel dose not have enough. Looks to be running pretty good so far!
