RE: Bob Cat Copy Falcon 120 Jet

I used Robart Large Hinge points on the elevator, ailerons and rudders and regular ones on the flaps because they are thinner.

RE: Bob Cat Copy Falcon 120 Jet

Hello,

I just leave them be. When the gear retracts the cables get slack but its not enough for it to get caught on anything. I drilled up at an angle right through the wood formers/gear...

RE: Bob Cat Copy Falcon 120 Jet

Thanks for the tips Tim, I will certainly keep that in mind if any issues arise.

What I had thought about was that if it leaked I could always order "Square section" O-rings from McMaster Carr. ...

RE: Bob Cat Copy Falcon 120 Jet

Eagle,

I made these like the original BVM brakes where the O-ring seals against the sides of the groove and expands out, nothing fancy. The inside surface of the groove was very precisely...

RE: Bob Cat Copy Falcon 120 Jet

I'm definitely interested...even though I have been working on my own, god knows if they will last more than a flight or two.

Let us know price please.

RE: Bob Cat Copy Falcon 120 Jet

Just a quick update of my build. I'd day my struts are 90-95% done with the exception of the main strut upper mount area (overall length) which I will determine when I start installing the gear.

RE: Bob Cat Copy Falcon 120 Jet

Here are two pics of the main struts once the spring was installed on each one. They feel really sturdy. Now I need to define the overall length and shorten them to my needs. Then machine the tops...

RE: Bob Cat Copy Falcon 120 Jet

Hello!

Quick update on the struts. The front one is pretty much finished and works great and the rear ones are about 70% there.

As discussed earlier, these will fit the stock wheel wells...

RE: Bob Cat Copy Falcon 120 Jet

Actually its a bit of both. I designed them and chose a spring so that when the gear is down and the airplane is on the ground they will be compressed (not all the way of course) making them shorter...

RE: Bob Cat Copy Falcon 120 Jet

Quick Update!

I reinforced the booms with a combination of gorilla glue, Medium CA and epoxy depending on the area. I went in from every opening I could get to, I think they will hold fine. I...

Here are some pics of the strut progress. The Fork was cut on a Wire EDM machine and that is how I was able to cut that shape. The leg was CNC milled and it is a clamp design instead of with...

RE: Bob Cat Copy Falcon 120 Jet

Yes I agree 100%, I have an FOD screen for it, I was just laying the turbine on there for pictures...The FOD screen will probably require that I grind some fuselage around that area but shouldn't be...

RE: Bob Cat Copy Falcon 120 Jet

Of course, lacking glue everywhere but I feel comfortable that I can get it up reliably with...

Thanks for the reply, exactly what I was looking for.
