Question
CG mig 27 drone convertion to edf
Came across a Carl Goldberg models Mig 27 target drone, let me say this it is one big foam plane. The Ws is 66" and the fuse is 77" all foam. I have seen a build blog/log of one of these planes and I must say it was cool, and it had a Wow factor just sitting still. I have seen a few electric puller set-up's and mostly glow, I must say the afore mentioned build was EDF. So I plane to follow in his foot steps so to speak and possibly make my mark also when it come to this plane. The job seems straight forward but I want to include ducting for smoother airflow and maybe some extra speed to boot!!
So my question to any and all builders especially edf guy's where can I find some ducting? I checked EJF but seems they are out of business, but they did have some useful info about ducting. My plan includes a 127mm fan unit, a bearing system for a fully flying elevator, and retracts. Also some carbon reinforcements along the fuse, wing tube spars. Some ply wood formers to stiffen and strengthen inside of the fuse and to hold down the ducting. This will also allow me to run push rods back to the tail section and some servo leads for the rudder and ailerons. As you can see I have been mapping things out. Power system is next I need at least 14-18 lb of thrust and that might be pushing it, I plan on keeping this build as light as possible so I can get as much speed as I can after all it is a jet!! I saw and here a lot of builders/flyers of these planes are using 61-91 glow and 60-90 electric, and the ducted fan conversion used a scorpion motor and 12s to achieve the needed power to get his 13lb. mig of the ground. Other than a BVM viofan set-up's which are top of the line and big money to boot. I plan on going with HK 127mm unit and find a motor to get my 15lb of thrust?? Hopefully I can achieve that goal also. As you can see my timing couldn't be better as the weather is changing here in the northeast and the days are getting shorter. so I plan on starting in October and finishing up around April. With this time table I can find what I need without rushing. Also may need some advice on the flying tail section, this would be my first, and my first EDF build and looks are important to me when it comes to building or converting!!! Please leave any info on ducting, power systems, tail sections even landing gear. This plane has room for days!! Thanks will post some pics soon. |
