Julian,

How long are those pipes?

I have some better ones for you to try.

You may want to get some front sponsons on that girl

before you get her wet. :eek: Sounds good in the back yard.

Thanks For Sharing,

Mark Sholund

That's Walt Radzinski's old twin 21, glad to see someone's gonna play with it. I like how after both motors were running you extended the transmitter antenna, some old habits die hard. A twin is still a twin even when it's a pair of 21's. B)
 
Julian,

I need the center of the engine to the start of the pipe

measurement please?

Thanks,

Mark Sholund
 
Julian, its great to see you are still playing toy boats. Sounds good on the stand. Good luck with the twin, once you get on the water. Richard D

i will post some videos soon.

im currently doing alittle things to this Twin and test it out and see how it goes it will be a fun but time consuming. 21 motors are a bit more of a challenge but i think i have the tuning on my Mac motors on point. will be testing some pipes and several other things and we will see what happens..

Tom,

I doubt very much if you will be able to catch it.

It should be really STOUT once we get the right set up

on it in Huntsville, AL. :D

Have Fun Testing, We Will,

Tom,

Maybe I will come down and be his pitman so he can learn to

get on the clock for the start.

I guess you can always break out the Cordless Sawzall. :eek:

Have A Great Weekend,
