Picco 1/2a
« on: July 01, 2011, 06:52:03 PM »
Just wondering if anyone that is using a Picco 1/2a engine is having broken crankshaft problems , some sites have this problem and saying that the crank opening was square cut , and a radius with a grinder would fix the problem?  http://www.rcuniverse.com/forum/m_8380332/mpage_10/key_/tm.htm

mine broke at 32,000 the shaft was relieved in the area where the problem was thought to be, it still broke in that area.
I believe it is breaking due to using a high rpm starter. I had no problems till I got a new starter?
