    48" Dumas pt 109

    I have a older built 48" Dumas pt 109 I'm looking to repower. I only deal with nitro airplanes and have no idea about electric motors. I'd .like to keep the three prop setup. What I'm looking for are recommendations for motor, esc, batteries, cooling of motors etc. Thanks in advance. Jerry

    Airzona,

    Depends mostly on how much money you want to spend. Check out these sites as they may give you some ideas. http://www.mackproductsrc.com and www.offshoreelectrics.com. Brushless motors are the best if you want speed but are more expensive then brushed motors, though they are getting cheaper. Especially on E-Bay. I have older AstroFlight brushed motors in my PT and Donzi. The Donzi is very fast with .25 size AstroFlight motors. They are not easy to find anymore though. I also have Aquacraft motors in 2 scale deep vee's and they are very good motors. I have my PT set up with 3 shafts but only the 2 outboard shafts have motors, the middle one free wheels. I haven't run it yet but if the middle prop gives too much drag I will just remove prop when I run it.

    Hope this helps,

    Keith
