I bought this model when I had my model shop back in 2005, that makes it six years old. It has had several engines in it, most recently an ASP 91FS. Over the last six years, we, the Frontier and me, have introduced many new R/C pilots to the sport of R/C flying. I decided that she needed to have an inspection and be checked out for fuel damage and many, many hard landings and a couple of very athletic cartwheels. For such a big model, 82″ span, she is not very heavy, 7lbs flying weight. It occurred to me that, given the price of 10% nitro fuel, it may be feasible to electrify the old girl. Originally designed for a .46 two stroke, the choice of brushless motors is extraordinary. I am new to electric power so I did my research and arrived at the following set-up. From Giant Cod (where else) a E-Power BL 4030 385kv outrunner, a Hobbywing Pentium 80amp Opto ESC and two Gens Ace 3300mah 25c 5s Lipo Batterys.
Anyway, glow engine & tank removed, I cut a hatch in the nose to insert the battery and constructed a cradle to support it. Giant Cod posted the motor mount quickly and although I had to modify the mount ( the shaft collar on the motor required a 16mm hole), the motor fitted well. I will strap the ESC to the mount so it will be in a nice cooling draft and the fuel tank hole should let enough airflow past the battery to help cool that off. Although, it will mostly be doing circuits and figure eights on the buddy box.
Below is the link to Steve Webb if you want a Frontier Senior. They are a very good aircraft to learn on, and if you fit a .91 FS it will aerobat with the best of them.
