Ok I dont live in W.A. but... You can go to alot of websites.
I ordered my crap from
www.toyeast.com Theres also
www.bitchar-gmotors.com www.sigmaautomotive.com and also
www.towerhobbies.com I think toyeast is really reasonable but if you want a 3.8 buy it from
www.tinyrc.com or bit char-g motors they both have 3.8's. Sigma auto only has selection but really expensive.
