Title: Yatsenko Bellcrank Width
Post by: frank williams on July 03, 2019, 09:12:00 AM

What is the size (width) of the typical Yatsenko bellcrank?  Some of the drawings on their site show 90 mm.  Somehow that seems small for the few that I have seen in person.  Isn't there a trend in the European models to have larger than 4 inch bellcranks?

Hi Frank

I have a couple of ships here  with  4.5 inch bellcranks, they seem to work very well, and  not positive but I seem to remember the  Yat  bellcrank at just under  4 inches

Thanks Randy, Lauri
I have some old rat racers with 1.5 in bellcranks #^
I found and measured the Max Bee plans and it shows a 100 mm crank. (3.94")
The Nemesis kit from Brazil has a 125mm crank. (4.92")
So, Sharks 110 mm (4.33")
Interesting
Thanks
