Digital,

I looked a the servo option but the engineering was more that I wanted to try at the time. So far my SM cylinder is working ok.

Copy that.. Thanks for the info...

I am using 2 air cilinders in each door.. now is perfect.. order the other cilinders from skymaster

Digital Pilot

One at the back im assuming?

heraldoboldrin

both in the back.. my front cilinder broke...
i put them together side by side... and did that in the rear door also..

all door stay closed with P300

Good to know.. Thanks

hello there, anyone knows the total fuel capacity of the 3 tanks combined? thanks

thank you Gary for the info, much appreciated.

Hey Guys,

Anyone have problems with nose gear not retracting fully? Mine retracts 95% but just doesn't have the mechanical power to pull that last bit up into the fuse. I'm running two jet tronic valves in parallel for the mains and nose gear. Mains work perfect.

Im thinking of running a seperate high flow valve for the nose but not sure if that will help. I'm running up to 110 psi and the nose still won't go up fully. Here's a video if it turns out.

Thanks
Levi

So far mine has been working. Have you flown yours yet Levi? How did your CG come out with fuel and smoke tanks full?

Hey Gary,

Have not flown yet mate. Next weekend hopefully. I'm about to weigh her and check CG in the next few days so I'll let you know.
Glad your nose gear works. I've not heard of anyone else with problems. Mine just gets real tight during that last 5% of retraction when the gear twists into the fuse. I've loosened off some bolts but will try a few more and see if that frees her up.

I could run a seperate high flow valve for the nose gear but as the plane is complete that's a big task to pull things out to access the air lines.

Any tips Anton or Likai?

Cheers
Levi

I had planed on using the electronic valves as well, however I was worried about the PSI restrictions of the valves. Jertoncis are about 140 max and the Xicoy is 100 max. Both great for mid size gearl. I've decided on the UP3 mechanical valve by Ultra Precision. Its capable of 200 PSI. I will upgrade to larger tanks to support the pressure. Will work the gear and doors just fine i think....

I'm running the xicoy valves no problem. One on the doors and another on the gear with separate x large air tanks for volume. I have the up3 in another jet but found it bleeds lots of air during the internal sequenceing

Digital Pilot

What pressure are you using on the valves?

bri6672

My Feedback: (6)

About 110 I have been using xicoy's for several years and have always run them at about that psi no problem.

Digital Pilot

Ok.. During my research, The factory said not to go past 100PSI max or the valve could possibly fail. This is why i was looking at other options. Maybe one valve for nose and 2 for mains or just 1 and 1?

Levi Wags

Thanks for the info Brian. Digital I'm starting to think pressure is not the problem with my set up. The centre yoak or junction where the leg pivots to twist seems tight. I had my gear sprayed at the factory so maybe some paint got in there and is binding it up.

Paint could very well be the problem. My gear had paint all over it and some in the wrong places. Hope you can sort it all out ok. I'm using Jetronic valves and 95-100 psi with no issues so far. I do have two largest size bottles on the gear and door system.

how much weight has your F16 dry (full ordinance or not)? do you have smoke?

heraldo

lovemykoko

heraldo, can you please post pictures of your 2 cylinders setup in the nose gear, my main doors close and stay closed with no issues, it's the nose gear door that opens during flight. thanks

heraldoboldrin

i put 2 cilinders in the back of the main door.. with that setup is perfect. My friend install just 1 cilinder in the back.. and keep the regular cilinder in the front.. also fix the problem.

Heraldo, mine is heavy, 62 lbs clean, air trap full, tanks empty. I have a smoke system. I have to fly it under the AMA LTMA1 waiver here in the U.S.
