Re: THE Fisher-Price Motor Spec Sheet

Thx alot dr. joe but i must say after our meeting today i am even more mind bottled. Every body keeps saying "the F-P is the strongest motor in the kit. I know im not the best in the world at math but a some people have checked my math and its correct i got the following


F-P has 5.364 FT LBS @ 126 RPM

The Van Door has 22.1 FT LBS @ 75 RPM

The Denso has 6.78 FT LBS @ 92 RPM

The Jideco has 6.144 FT LBS @ 85 RPM

Please would some body check this information to make sure it is correct because if it isnt i dont want others to use it (me) and i would like to know what mistakes i made in calculating these numbers

Also if these number are correct although at diffrent RMP's isnt the Van Door stronger than the F-P .... thats what makes me think i have made a error.

Also ive read that the van door is not good for arms and needs to be operated at high rpms .... well lets say we needed 90 ft lbs and gave the van door hmmm 5 to 1 ratio would the rpm of the van door drop to about 15 ..... if so is that safe for the van door because i know theres some sort of fan inside
