I'm the new owner of Mac Attack and I paid my 25.00 dollars through paypal but cant seem to figure out how to get logged on, anyhow mac attack allowed me to use his logon. On my maiden voyage, I switched props from A2 to A4's and after the first good run at speed I noticed a funny steering issue, I throttled her back and tried again, all rpm no power, trimmed the outdrive up, missing front prop, so I need a set of A4's or a front for spare, Mike informed not good to mix match props, so I have a good back for sale I guess. Help Erik(still the proud new owner of 26' blackman)
