Flanker, Abosultely no problems using the full bypass. It is the only way I would consider. The bypass makes for a very clean, professional installation and certainly helps protect all internal airframe components. There's lots of room in the Sabre fuse as the enclosed photo shows. I would however, strongly recommend using the on board starter motor. I did find it difficult to postion the starter wand that comes with the kit into and out of the bypass. For an outside the airframe installation the starter wand works fine. The starter motor simply bolts onto the front case with three small bolts. I put a Tamiya connection on my and use a six cell pack connected to a momentary on-off button in a small ground support box (Radio Shack). Simply plug in, push the motor starter button and the process begins.
