You want an F-16 made in the US? Call Lockheed Martin, soon to open in Greenville, SC, but Im afraid not even that one is 100% US made, more like 50%.
BTW, I have many reservations on buying FEJ, just curious what in their website draw your attention?

Hi guys. Regarding the shortfall in the main/centre fuel tank size, although Carlos at CM jets has done a terrific job increasing capacity and makes really excellent tanks, a friend and I decided to utilise more of the space available over the air intake pipe.
We moulded up a fibreglass tank that fits all of the space and doesn't protrude into the engine bay. Volume of the new tank is 1.8 litres, whereas the original centre tank is 0.8 litres. The only issue is that the two lower lobes hang down either side of the inlet pipe, making it difficult to organise clunk pickups. Of several options available to cope with this, I chose to divide the tank into two with a vertical divider and not have any clunk at all. The tanks so formed, are short but high and with the outlets at the lower rear corners, they would only suck air when nearly empty and on a downline. I have the standard saddle tanks feeding the new dual centre tanks, then forward to the Intairco UAT.
The only drawback so far is that filling nearly all the space over the air inlet makes it difficult to feed all the fuel lines and servo leads forward to the nose section. However, some careful enlarging of the existing bulkhead cutouts has made room. Ground testing shows that this setup seems to feed fuel without problem, but the maiden will be the final proof.

The photos show the wooden plug trial fitted into position.

Good job good idea but not a good design. not to throw rocks but by having bottom pick ups and no clunk system, aerobatic maneuvers are out of the question except for loops. little by little the UAT would be filled with air .even if you put a pick up line on each side the air would be the first to exit the tank as it's the path of least resistance also the tank being so far forward could lead to a very nose heavy airplane on take off and with a flame out things could be ugly. other than that something i agree,needs to be done about increasing the fuel capacity just my two cents. i hope it works out as i have one waiting to be built

Every F-16 made here in good ole Greenville SC will come complete with a plate of pulled pork BBQ, mac and cheese and a glass of sweet tea. For our special friends we may even include a shot or two of peach moonshine.

Hello.
Nothing new here?
How is the G2 version versus the older version.
Is it easier, landing gear is better?

Can anyone tell me what weight is the dry G2 version (without fuel)?
I'm waiting for answers.
Thank you,
Dan.

This jet seems to be an anomaly. I gave up and bought a foamy turbine F-16( apples and oranges, I know). There just never seemed to be any consensus on this jet as to it's quality or reliability.

You ever coming back to KY jets?

Hi.
I have ordered this F16 these days, probably I will get it in May.

A friend in Germany has already received it and says it has a weight of 9.5 Kg with servo and M 100XBL turbine but without batteries.

It seems a very good weight for this size.

Hi Dieselman 1220,
My 1:6.75 F-16 project is on hold for the moment. I've been having issues with the pneumatic gear, where I was trying to sequence the main gear locks so they didn't stop the gear from retracting when it all fired together, but that became a plumbing & sequencing nightmare. Flying without some sort of main gear lock wasn't an option for me. The mains will fold under any load, if the pressure gets a bit low or is lost altogether.
My next approach was to try to electrify the whole thing, but the nose door rams are too small and the space is too tight to get even a micro servo or actuator in there! I have fitted Firgelli (now Actuonix) L-16R linear actuators to the mains. The 150mm stroke and 150:1 gearing fits with very few mods. I used a Lado RS666 Short version actuator on the nose gear, but it didn't fit so well. I do have it working, but I'm not happy with the result and wouldn't trust it in the air at this stage.
A good, but expensive alternative would be the fit an Electron nose gear. The small one is probab;y the only one that would fit, but it may be a bit light for the job. Nevertheless, I have found that Electron retracts are beautifully made, reliable and very strong.

Pity really, about the gear. Like all of Anton's designs, it's a very well made aircraft and appears to fly really well.

Back to the Meister Zero for now.

An easy solution here is to cut the tank in two and have a clunk on each side. Problem solved. Always use monster mega tank fittings from which ever manufacture you like most, JMP, BVM, etc....

Hi Ravill and good thoughts.
Certainly that is a solution, but I considered the shape of the resultant two tanks ( short-front to rear, but deep-top to bottom) and found that the clunks would have a few problems getting to the extremes of each tank.
However, now that I'm fooling around with the landing gear, I will probably do as you suggest and fit the two clunks. It doesn't change te plumbing very much. The main thing is that I've gained and extra liter of fuel! I also fitted a 350ml internal taxi tank, which I've found will just give a start, hatch on and taxi to the takeoff point. As it's the first tank to drain, there's no weight or balance penalty.
I've just got to be careful of the C of G with the extra fuel in the mains.
I've fitted a JM 200 XBL to it, which is a huge over-kill powerwise, but as the engine is slightly smaller and lighter than the popular Kingtech K-140, I've just dialled back the top end RPM slightly as advised by Gaspar to a saner power level.
Thanks for the thoughts.

If it was me, I'd limit the thrust output with my thumb, its WAY more fun! LOL!

Have fun man!
