After sitting on a shelf for 2 years, my 1/6 scale JL F-16 was finally flown for the first time. This one is definitely a KEEPER.[8D]

Congrats David... I'm glad that all went well and that you're happy with your bird. I am trying to learn patience from you. Yours sat on the shelf for so long,,, and unfortunately, mine is still sitting in the box :-(

Good luck and I hope you now get to burn a tonne o' kero.

The F-16 is really a sweet flying plane that handles extremely well and presents quite nicely in flight. Got my second flight in today with a shorter take off than yesterday. Everything was going well until the engine flamed out as I was setting up for a landing. If only I had been able to stretch the guide 75', would have avoided tall grass and weeds. No big deal, a little glass cloth to the nose and a new nose gear, and its back to the air. I must admit, this is one of the best flying jets I've had in a long time.[8D]

David/Michael;

Need your help! I want to maiden mine but still feel unsure about the throws and CG, don't want to start a take off roll just to find it won't rotate before the end of the runway(700 ft), would like to use flaps to help, I was not able to move the main gear up too much (only 1/4") because mine is an early version, haven't modified anything on the nose gear, I want to avoid the jumping into the air. Power is from a Jet Central Rhino.

Please HELP!!!!

I used the same setup posted by Goose F22 in "POST #187" 10/25/09. The only deviation from his setup is the CG I used was set at 198mm, and I didn't use flap. I was planning to try flaps on the third flight today, unfortunately flameout sent me home early with some repair work to complete. My first flight and second flight were both done with max throws (60mm) on the elevator and 25mm on the aileron with 30% expo on all control surfaces. This work for me. The take off roll for the first flight was approx. 550' and when full elevator was applied, it rolled another 50' before leaping from the ground and going vertical. Since I had expected this to happen, it was no surprise. The plane required just a few clicks of down elevator to trim it to straight and level flight.

To help stiffen the nose gear, I removed the nose gear inner strut and placed a half inch piece of 1/4" dowel at the end of the spring. Doing this raised the nose on my 16 approximately 1/4". Doesn't sound like much, but the plane rotated in under 400' today.

I really wanted to see if flaps would have made any difference on rotation, but I thought it would be best to see how the plane would respond to flaps while it had plenty of altitude before using flaps at take off. Maybe once the plane is repaired, I'll get to try again. [8D] You will love how this plane flies.

By the way, I used a Rhino LPSS for power. 700' of runway should be no problem for you. The runway I flew from was 800'. I was actually trying to get comfortable with my plane inorder to fly it from the local field which is only 400'. I feel confident that after a few more successful flight from the 800' runway, the local 400' runway will be no problem. Good luck on your maiden flight.

1/4 inch is fine. set your cg at 200 mm with the nose a slight heavy. With throws on ail, use about 1'' of travel up and down from the outside of the ail. on elevator i will have to measure at a different time.

i use no flaps, however Malcolm uses flaps. I find it wonderful without. i also have an additional 12oz fuel tank in the center belly in front of the former near the landing gear. in that space under the ducting. on a p200 i get 7:30 flight with a bit less than a 3rd of a tank remaining in each of my sattles and my uat and header tank full on landing.

After repairing nose damage, installing a new nose gear and larger diameter fuel tubing, and applying colors for old eyes, my JL F-16 is ready to return to the air.

David:

Looks good! should be easier to see now, I have the same concern as mine is the gray camo, could you answer a question for me? is your fuselage the 2 piece version or the 3 piece version? (two piece is main fuse/intake part 1+ nose section part 2, 3 piece is main fuse part 1+lower intake part 2+ nose section part 3)

David Jackson

My Feedback: (15)

My plane was one of the earlier versions, two piece fuse. I really didn't like the original gray-camo color of my plane and had actually wanted to repaint it and some later time. Unfortunately, my second flight forced me to paint the plane earlier than planned. Looking forward to getting more stick time with the 16 real soon.[8D]

David:

Thanks for your answer, mine is an early version as well, I have been trying to get a hold of someone with an early version!!!, so you say 60mm elevator, 25 mm ailerons, 30% expo and 198 mm CG right?? Lte me know, I'm anxious to maiden mine!!!

BTW did you have issues with the main landing gear fittng corretly into their wells? The early version fuse has scale gear doors that are smaller than those on the current versions, so it's a tight fit for the gear for the early ones, your gear coming up OK on retraction?

Thanks!

Ruiz,

The numbers you posted are the ones I used for cg and throws for the control surfaces. It seemed to work fine for me. However after rereading this thread, I may move the cg back to 200mm as was mentioned by Malcolm and another owner of this plane.

No issues with the main gear fitting into the fuse. Just one thing to keep in mind, if you didn't do any mods to landing gear to raise the nose a bit, expect it to leap off the ground. Once you get it in the air, it will handle quite nicely and you will definitely enjoy the way the plane flies and also lands. Good luck on your maiden flight!! [8D]

Is the C.G any different on the new version of this Model? Not sure which one Malcom has.

Ruizmilton

My Feedback: (29)

Should not be CG difference differences seem to be limited to larger main gear doors and 3 piece fuse vs 2 piece early version (less expensive to ship), Malcom had a late version, you can tell by the front turbine rail former being straight on the bottom, the early one is curved, seems the late one is straight because of the larger gear doors for clearance, also allows a main gear mounting position higher on the former to help produce positive wing incidence

Jeremy_D

Ok good to know. Thanks

Jeremy:

Sorry I did not finish my argument, David is flying at 198mm, Malcolm used CG's between 190 and 195mm, that's why I believe there should not be a CG difference since both David and Malcolm describe very similar in-flight handling...

Here are some photos of my ACE In the hole F-16. It flies really nice with a Rhino with stock pipe. I have air brakes, operational canopy on mine. will add an afterburner light system later.

Guys , since these last posts earlier in the year and after experimenting and some advice from a full size F16 pilot, I have been flying with the CG moved back to 225 mm and everything is fine , it rotates quicker and flys slower at HAOA and responds to the flair much better with flaps on 40 degrees , seems faster in the roll and altogether a handling improvement so feel secure.... I have one friend who went to 230mm and found the plane OK but ultra responsive and came back to 225MM.. so feel free try it you will be ok...MK

Malcolm,

Thanks for the updated information on the F-16 cg. I did move my cg to 225mm in September, but a few minor issues with brakes, other projects, and the recent cold weather have prevented me from getting the plane back in the air.

hey mr kay what happened to the information from u about the JL crew stating they test flew one of these with the cg moved back to 240 ect but they recomend 230 mm i beleive u mentioned if ud like i can post the original back n september i beleive n i now ur posted the cg at 195 lol so whats up with that?

imperio

My Feedback: (5)

ok my bad for some reason i got the wrong idea sorry bout that lol ive got mine right arount 225-230mm n if the ship is to responsive uve got too much control throw n need to reduce ur end point, personally i like the ultra responsiveness n so ive got alot of elevator throw n fly tailevators n flaperons together n ya have to slave the aileron n elevator servos together for that cause the ******* radio trys to prevent this kind of mixing lol n fyi cheapo foamies make for really good test dummy craft when trying different control configurations n r a worth while investment compared to finding the hard way a control config doesnt work together n a turbine model costing $10,000 ect, ive learned alot from this kinda expermentation plus ya get n more flying/practice ect, mine balances by picking the jet up by the former just over the turbine that bolts togethe with the uat tank full a bit nose down but balances basically perfect uat tank empty[8D] hey what kinda flight times r u getting anyone with the stock tanks n 1 uat tank?
