a few pointers.....

first off ,definiteley a very stupid thing to do..........

a minor detail...
this heli looks like a raptor 60 to me (not 50), this one had the tt-70 pro pre-installed (won't fit the 50). also the frame on the 50 is made of plastic.


30:1 gas/oil ratio without a needle bearing on the crankshaft/conrod is a bit too less i think.

without the bearing i think the same oil content as glow fuel should be used. that is around 18% oil.

it sounds like a tad too rich on the lower rpms. maybe a walbro carb would do the trick.
