Speedmaster 20 mono, good day testing

[P THOMAS]

Went out testing today, 75 degees in Illinois in Nov.

Ran the Speedmaster 20 mono. had some good runs and speeds. This is the US1 B mono that Bob M. wanted to buy for $50.

Looks good Phil. Sounds like its 2 staging on the pipe.

Well now that you have that out of your system, it's time to stop playing

With boats and start building some boats.

Great run, Phil. We have had great testing weather in MN also. Only the second time in 20 yrs running r/c boats, that we have had a November like this. Richard D

Is that what is sound like to you too? Really picked up more speed when it did. Cooper pipe set at 7 1/4 but still mills slow great too.

58.6 mph is srtollin' for an X437! Got the RPM going on baby! Will you take $75 for that boat? LOL

Bob has first dibs on it, if I sell. Do need a new rod for it though, email me if you have parts.

 

[Ian Inverarity]

Very nice, sounded like good revs! B)

Phil, you need to sell me some of them vitamins you give that motor.

Sounds really sweet.

Excellent! I believe that was a 3 stage run. You do not hear that very often. I'll bet if you felt the carb, it would have ice on it.

Hi Phill

ZOOM ZOOM offer still stands

Phil,

Nice runs back to back.

Aprox. 35,136 RPM that is rollin for a MAC-21.

Not many other motors can do that.

Mark,

Is that based on measurement from the sound? If so, how did you account for the doppler effect of the boat heading directly towards the mic?

Cheers, Ian.

Thanks, but setting a timed record with backup runs is harder than just zooming around on the radar.

Yes, I bought that motor from someone, it had some mod work done, and the piston fit is real good too.

You figured that rpm from the prop and speed reading ?

 

[cooperpipes]

Hey Phil

Great run looks like that pipe and motor are working real good together

Phil;

Give Stu Barr a call.

order a rod for a Valvola.

Phil and Ian,

That is correct.

Simple math with the speed and pitch of the propeller.
