Hey , you have just helped me change my mind !! I have been thinking of running two nitro engines in my newest donzi build . I thought it would be a little bit messy and what not . I have been looking for some trannys and electra start system , but unable to find it . I will probably stick with my astro flight 40 motors . I have run these and 25 before . The 40's really push the donzi good . Well electic set up is easy to use and trouble free !! Nitro does sound/look good in the 65 donzi Though !!! Here's a couple pics of one completed in my pond running with two astro flight 25's !
