First step is to install the Brodak electric conversion kit. It seems that E-conversion instructions, at best, are only a guide. I found a picture on Stunt Hanger of Brodak's E-conversion. This got me headed in the right direction. I then used the full size Brodak plans to locate the motor. From the plans I was able to get the motor thrust line in the same place as the wet engine. I also was able to get the spinner back plate in the right location. Per the Brodak instructions You build in the motor to the point it takes surgery to remove it. This didn't make any sense to me. The chance of getting crud in the motor during finishing is enough to make it a bad deal. The other problem is battling the the weight of the motor during the rest of the build. I made the noise ring removable by mounting it with 3 wood screws. Hard wood inserts imbedded in the balsa wood secure the wood screws. It will be impossible to use the fiber glass cowling that came in the kit. I will carve a wood block to colse in the bottom of the motor. It will have an air scoop to force cooling air over the ESC.
