just an idea for u on engines i know u said that u want to run a 2 stroke becasue of money issues but if its not to expensive for u hobbyking.com out of china has asp 4 strokers for great prices in case u werent aware asp and magnum are the same motors they go by magnum in the usa and canada. i just ordered and recieved my asp 120 4 stroke a couple days ago and the thing runs great. i did a lot of reading on them in these forums here and had a lot of people saying good things about them as well as some saying not so good things. ordering things out of china can be a bit of a gamble since u dont really have much of a warranty but for that price i couldnt afford not to buy one and im glad i did. all my other motors have been o.s and super tigers, but if i can keep getting lucky with these magnums then i think all my next motors will be them. they also have a 91 4 stroke for 129 bucks and a 61 for 99.99. just something u might want to consider. the web address is www.hobbyking.com oh and if u sign up an account with them u get better pricing on items!..anyway my .02 cents
