rene is right, tomahawk list it as 2.8 liters All I know is that with a P-80se, I get 8 minute flights with plenty of reserve probably could do 10 minutes depending upon throttle management

I have a question on the thrust tube installation. Obviously you use the two tabs to connect it by the turbine, but where it exits the aft end of the fuse, do you just let it float or friction fit out the tail? I wasn't sure if only using the two tabs was enough to hold in place.

Mine was a tight fit going through the rear of the Jet had to sand the hole a bit, protrudes thru the rear of the Jet around an inch. Don't worry about heat it stays nice and cool

Thanks Rick... it's definitely a nice double walled thrust tube, and I wanted the ability to remove if necessary. Nice to know the heat isn't going to be a factor. I'll do the same and sand enough for a tight flt.

Well, I finally got the Futura sitting on its gear for the first time tonight. moving along a little slow. All control surfaces installed and setup as well. got the tanks installed with a simple light weight design. Also shaping a cardboard template for the equipment deck. I ended up using the BVM canopy hooks. also used grey foam board for cockpit base. Just got word my K-120 is finally on the way from Taiwan. Thought I just share some of the progress

I was curious on how people attached the tail cone. I wanted to use some 3/8" (9.5mm) button head canopy screws, but they're too long and would go through the exterior wall of the thrust tube. seems like only around 1/8" before hitting that outer wall. very tight space, or does it matter to screw into the outer wall of the thrust tube?? Rob

No, doesn't matter. You may drill holes of exterior wall a bit greater(or make it oval) and the outer wall is drilled to hold the screw. The points of the screw entering the tube may be cut later on.

With the holiday I had a lot of extra time to work on the Futura and was able to finish it.. Did the first start with the K-120G mounted in the air frame yesterday and final weight and balance check... Now if only the snow will clear off the runway!

Rick, I really appreciate your help. I read your build on RCCanada and got some additional tips. I'm new to jets and just trying to take it all in.

how did you guys secure the rudder hinge pin? I really dont want to bend the top and tape it to the top of the stab. I'm in the home stretch on mine and haven't figured out how I want to secure the rudder pin.

Hi BoomerSooner.. Good question. Mine seems to fit tight enough to leave as is. I'm really new to the Futura and haven't even maiden-ed it yet. so I'll let the experts chime in... but if it's fairly tight, I don't see an issue, just something to check. Is yours really loose?

Nope not too loose but just feel better about securing it. I worked it out today. Took a set screw and put the hinge pin into the Allen hole in the set screw then soldered them together. Then I took a Dremel thin cut off wheel and ground a slot in the head of the set screw to be able to use a small flat head on it. Opened up the hole in the top of the stab a bit and screwed it in. Good to go now. Hopefully have mine finished up in a couple days. Just need to finish up the equipment tray

Hello to all Futura 1.9 owners!

I have a tricky question - can you please measure the width of the fuse in the widest point (intakes), the reason for asking is - I'm trying to figure out if the plane will fit my car's roofrack so I can have a bigger jet inside and smaller one in the rack. I know that UltraFlash for example fits with no issues (tried to put my friend's UF there - no problems), but Futura seems much wider and thus I doubt that the rack will actually close.

It's about 14.5" at the base of the fuse at the intakes.

Just about to start building one of these, just deciding on a turbine, either a 100xbl or kingtech 120g2, I have used jetsmunt a few times and like there engines but I am tempted by the 120, any one using either of these ?

Hi, I used a Jet Central Cheetah 160 in mine. I sold my first one and then my wife bought me a new one. The Black, White and Green one.
