Also did 1 servo on my stab.
Did not like the 2 servo steering for the stab.

Update.......do not get the Robart L/R trailing link strut mains for this plane. They will not fit.

I installed the nose gear on Friday night. I used the fork trailing link Robart gear here. It took a tiny bit of mods to make it fit (mostly filing and sanding). The hardest part is that the Airpower retract is not quite 7/16 so I had to file it to make the Robart Strut fit. The trailing linke will stick out of the fuse though. I had installed a nice nose gear door that opened and closed with the gear. Then I realized after the fact......dummythe gear has to rotate for steering-so I had to take the door off and I'm rethinking how I can attach it.


For the wings......the trailing link gear have such an angle to them that it puts the wheel just inside the flap. Unless you want to move the entire gear mounts to a new place (too much modding for the price of this jet). I'll be ordering the standard L/R Robart struts here shortly.

had the same problem so i made my own trailing links up which work great heres the pic`s

Wow!!!

I want a set like that. How do I get you to make me a set???

Mav
WRONG PART OF THE WORLD BUT I CAN POST SOME DRAWINGS SO YOU COULD GET SOME MADE WILL THAT HELP ???????????????

I use AT mainlegs see page 18. Bought from Motors and Rotors, but had to cut them down to fit. They have been brilliant. I am up to 76 landings now (I think), nad most of them on these gears. look on youtube to see them in action, under my user name, tim777jet.

Starting to put some fuel delivery components into the fuselage today, just ahead of the tank. UAT, pump, solenoids, filters, on/off valve, Festos. Ain't no way that I can reach them wing hold down screws anymore. []

Now I see why most of you guys leave your wings on permanently. []

New2jets, your homemade oleo's look great! Any chance of posting details on how you made them and the materials that you used? In my earlier post I said that I was not happy with my existing setup and will in fact use 3/16 wire struts until suitable trailing link stuts can be fitted. Here's a couple of low res pics taken off video of first flight.

The wing hold screws are put in through the bottom of the fuse.... Through the square opening.

I'd really like to see yer put those two front screws in place using that bottom hatch, and the tank in place.

I can. My tank sits RIGHT up against the main alum Spar. Although I switched mine out for a Carbon one. Noahb's fuel tanks sits RIGHT up against the main spar also.

It's a bit tight in there but not really much of a problem. Instead of the supplied bolts I bought some at Home Depot that look like a wing nut welded to the end of a screw. That makes it easier to tighten them by hand. I had to also replace the blind nuts in the wings with matching English ones for it to work.

Yesterday I made the maiden flight on my Falcon. All was great, but I could not use the retracts, due to a servo failure . I flight it with my new TM8 2.4 module. It seems to work perfect.

Some picks

I'm new to this forum.
Is there any info on a propeller version of this plane?
Would like to try it with a Saito 180, then maybe later with a turbine.
Advise.
Thanks,
Steve

Yes , it`s the blue sky,
I think the visibility of this plane in a cloudly day, must not be very good.

Hi. Just got a Falcon 120. I will be using a 14# thrust turbine for power and I have a few questions.
#1. Are the hinges that come with it OK? If not, what is recommended.
#2. I have seen mention of the Spring Air 700 retracts as a good choice. Are thay a drop in or do I need to modify the wing to install?
#3. It seems that removing formers in the rear part of the fuse. is common to make room for fuel tank. Are these formers complety removed?

Hi Ray, welcome aboard,

1 - I used some robart hinges and some pin hinges, dont use the mylar plastic hinges supplied.

2 - undercarriage, dont know this type, others can help I have used the Graupner units really really cheap, i think they were great, lasted for quite some time, and ok if model is kept light and fly off tarmac, I upgraded to the Euro kit plastic units as i fly off grass. Eurokits are about 1.5 mm too wide to fit in wing and nose rails so either need to file the side of the plastic retract unit down or take a bit off the hardwood rails. They are cheap and cheerfull but work well another and withstand a bad landing.

3 - Didnt remove any of my frames, i used a dremel and sanding drum to remove small amounts to allow tank to fit, use a Persil wahing liquid bottle fits well and is a good material, doesnt crack in winter and cap has lots of threads. It is stumpier than a coke bottle, so helps to keep the fuel closer to the CG.

Cheers Tim

I have just finished reading Dick Pettit's review of the Falcon 120 in R/C Report. In it I see that he uses two big flat washers under the screws that fasten the horizontal stab between the two verticals. That's the single screw on the vertical stab straight above the rudder servo. You can clearly see them in use in the color Pics on pages 64 & 65, and also on the cover shot. They look kinda dorky, but are probably very functional, even though I don't see them used this way in either the instructions, or picture in this thread.

How many of you have taken to using them this way, or think that it's a good idea ?

Hi I used turn up washers with counter bores in them to take the screw head and chamferd them off and painted white , i think this is very important that you use these other wise the screws will pull throught the wood .

They will drop in, at least mine did. Nose steering is something you will have to work out. Bob
