Throttle travel on Accucraft Ida (or Ruby)?

[John A. McNeil]

Hi all,

I am new to the list. By way of introduction, I have an Accucraft Ida 
which I have fired twice. The 1st time it ran great, but fell off the 
kid's LGB track going too fast around a curve (no damage). I just added 
RC so I can run it on the San Diego Garden Railway Society's track at 
the Walter Anderson nursery. I have also built a Hartford Products 4 
wheel flatcar and a derrick car. I have a caboose with really cool 
Carter Bros. swing motion trucks under construction. You can see 
pictures here: http://www.xardas.com/

Now to the question: The 2nd run of Ida was with RC. With the throttle 
open just a tiny bit, the only way to control the speed was with the 
Johnson bar. Is this normal? What is the total throttle travel I should 
set up (measured as degrees or distance moved by the end of the arm 
would be fine)?

Thanks,

John
