Hello everyone,

Yesterday I have received my new motor; this is the Webra 160 Aero XP.
Now I have reed the instruction book and was wondering if anyone is using the following methode:

The instruction book tells you that if you use a higher % than 15% nitro you should use a
SHIM WASHER approx 0.2mm, this is to reduce the motor compression. (So the instruction book said)

Any thought about this??
How should I do this??( method )
And where could I get this??


I thinking of using the Morgan's 30%Helli fuel for better lubrication.



Thanks in advance for the info,(suggestion)

Danny
