Kind of depends on your skill level and how much time and money you have.It is certainly more satisfying to start from bare bones and do it all yourself , that way you know without a doubt how your boat is made,and can control the quality and hardware pieces better.Most of the outer hardware is going to be usable on a conversion like this,mounting the motor esc and relocating the reciever and housing to mount batteries is really up to your own imagination and skills,and what type of e-system you will use.You can buy these kits now that have all the hard work done for you,and you just choose the e-system that best suits your needs,but remember the old addage...speed costs money..how fast do you want to go? I bought a toysport jolly cat a while back that had all the hardware installed and I just added my own e-system to it,...pretty easy..only set me back about 1200.00. I doubt I could have done a better job at building that boat myself .Very high quality work.
