Check out Tam jets plug and play DS-94 `120mm schubeler fan.
I have two of them and they are a work of art. Tams A-4 is 16 pounds setup for EDF. It's a turbine plane converted too edf.
It sounds unreal.. very much like a turbine and does about 150 mph on 12s set...
I have one in the shop to build after my cermark F-16 which is also a turbine plane.
RC groups has alot of EDF info.. The hard part of your conversion is ducting..
the intake ducting on a EDF is very important.. you can use a cheater ring on the fan
but it won't have the top speed like a full duct plane... I'm new too large EDF's but I'm learning fast
let me know what I can do to help... good luck..
