Not a wonderful result, the Falcon 120 is a big, draggy aircraft & it had to fly at high throttle
settings to make headway & was a...

Prop availability is wider than you think, direction can be reversed remember. ;)

Any three blade prop is on the shopping list, just remember to put the 'curvy side' to the front!

RE: Bob Cat Copy Falcon 120 Jet

I recently had my first in-flight servo failure on a medium size electric.

One aileron servo went to about 1/2 travel & stayed there solid whenever power was on, power off & you could move the...

RE: Bob Cat Copy Falcon 120 Jet

If you keep the booms & tailplane/elevator together (On the Tornado they recommend glueing it all together)
as one piece it will mean just two plugs versus one if you put another reciever in the...

RE: Bob Cat Copy Falcon 120 Jet

Like this one made from 4 pieces of aluminium angle?

It's fitted to a smaller Bobcat 50 with a Wren 44. - John.

Yep, that's the Kavan electric brake. I have one fitted to my jet. They are still available from Bruce Tharpe, I bought the Reaction 54 wheel & brake package for my scratch built jet.

Thanks Woketman, it was fun to do in a different colour scheme.

This take off pic is probably a bit clearer. - John.

I had to repair my smaller Bobcat which involved recovering the wings & filling in the holes in the tailplane.

Hi Tim, can you post a link to the vid of your Falcon.  Also, do you have details of the LED so I can chase some up down here? - thanks, John.

RE: Bob Cat Copy Falcon 120 Jet

I went to Wang & I remember just one Bobcat 120 crashing, a red & white one (custom painted) with a great finish.

The word was one flap retracted during landing & he was not high enough to take...

RE: Bob Cat Copy Falcon 120 Jet

Thanks for that resjets, I have fiddled with similar ideas myself. Have you considered some of the whitworth screws (1/8?)

The threads are coarser which will speed the operation up a bit & may...

That's cute. Did you use a servo slower or modify the gear train somehow? - John.

RE: Bob Cat Copy Falcon 120 Jet

Yes, you do have to bend the legs back, but only if you make a complete c__k-up of the landings which would at least bend a strut. Normally I check them after a flight anyway, 99% of the time they...

With all this cutting, filing, fiddling has anyone considered just simple wire legs with a coil in the top like has been used for 50 years?

After all, these are supposed to be cheap, simple, fly...

RE: Bob Cat Copy Falcon 120 Jet

No, but tried an airbrake on the bottom of the smaller Bobcat 50 (no flaps).

Makes the speed on approach much easier to control, introduces a small amount of pitch up.
Full deflection is...

Hi Tim, sorry no video. Here's a couple of pics. Keep in mind this is the smaller Bobcat with a Wren 44. This has no flaps, hence the airbrake. The airbrake works well, you can approach a little...
