Cougar, just waiting to test EDF

The EDF arrived DAMN FAST TOO! less than 3 days. :O I got the Cougar all assembled and wings glued on. Landing gear in & servos mounted. Only a few things left to do.

The EDF is very nice, Personally I took the heat sink off and applied some very good thermal paste to help keep the motor cool, i know it will be messy if i have to take it off, but that’s minor.

EDF motor,




Here is a picture of the jet on it’s top. All the tape pieces are reminders of what left to do and holding the bottom pieces on so I can drill and mark the screw holes.

EDF mach up !


After putting the EDF in I noticed that the battery i have will not keep the front nose wheel on the ground, so I cut a piece of wood to make a longer battery tray, so i can move the battery properly to get correct cg. I won’t be gluing the wood in, because I still may need to do maintenance on the front wheel.


Cougar Wing Assembly

Well did the method using 2 sided tape between servo & plate and epoxy, as suggested from professional and more experienced builders..

This just took me 2 hours for ONE WING!! LOL SHIT! no kidding this thing calls for 10+ hours for a full build..

Working on the Cougar,

well, after calling and talking to Hobby King, they said the servos I bought will be just fine. As long as i’m not trying to fall from the sky under full power and do a full pull up to get out of it then i’m fine 🙂 SO I started off with testing each servo, binding my radio to my R7 receiver, and making a plate for the receiver to sit on & mounted a servo for the front steering wheel.

Servo’s I ordered, and going to use,

Turnigy MG90S Metal Gear Servo 1.8kg / 13.4g / 0.10sec

This morning I was board, so I taped the wing and put the landing gear on ( dry fit )

radio mounting plate, ( need to epoxy it in. )

with receiver,

receiver bound & testing servos.

Did some research, and…

Starting on the win & servo block gluing. Just wondering before I make the step, should u use wood glue or epoxy ? ( manual says epoxy ) but thought I would ask if there are other suggestions. I will also use wood clamps to hold in place too while it cure’s.
