North American F-86 Sabre (Tomahawk)

Today I started with the build of my dream jet :) It is a Tomahawk F-86 kit.

I think this will be the color scheme:

I picked up a kit yesterday, barely fits in the car

Looks like a nice size :)

Lots of parts......

I started with mounting the rudder. Fits nicely only the gap in the top is a bit to big, i will fix that later.

Next step will be mounting the parts to the elevator.

Gefeliciteerd met jouw nieuwe aanwinst, het is ook een van mijn favoriete jets! ;)
 
I started with the horizontal stabilizer. The 3 parts are connected through gfk strips through the edge of the parts. A little difficult to get the glue through the holes and not have it run everywhere.... a good mix of microbaloons and silica powder did the trick. In the area's of the hole / strips the parts are very tough now. I also glued the scale joints and painted them.

I got the flaps and aileron mounted in 1 wing. The flap fits great to the top but has a bit of a gap at the bottom. I choose to align in the top because it looks better. The aileron fits almost perfect and the throws are just enough. I only have to clear the bottom a bit more to get the last 3mm.

Nice Project!!!

Nice Project!!!

Hi

The F-86 from Tomahawk is very nice, the horizon jet Team flew with up to 5 planes. It is very spectacular.
On YouTube are a few of Videos from These f-86 in the Skyblazers Scheme. Nice Project👍🏻👍🏻👍🏻👍🏻

Best Regards and happy Building Time

Slowly the build is speeding up :)

The wings fit great together, flaps and ailerons are fitted, gear is installed. Throws are exactly what is needed also. Gear is a bit to much outwards but it will just fit in the fuselage.

To get the right holes in the wings i created a simple tool. Maybe the hard way (3d printer) but it works great.

The fuselage parts are joined and fit quite good. 4 bolts secure the 2 parts together and 8 metal pins make for a good alignment.

I started with the placement of the motor mount because it is also the mount to join the fuselage and wing. The tank fits nicely in front of the motor. I need some more space then my shed to fit everything to gather.....

The motor mounts are glued in place. They add a lot of strength to the fuselage. I will add some reinforcements where the wings mount.

The mounts for the pipe are ready. This way the screws are more accessible what is better for transport. The mounts are not glued yet because the final engine alignment will be done later.

The wing plugs are glued also..... but how do you make sure they stay in the correct position when drying? Like this:

Mounts for the pipe

Mounts for the pipe

Hi
Beware to have the perfekt distance between the pipe and the turbine. Very critical with evojet. On the picture the distance seems too small. Ask the producer if you are not shure

I always use 2.5cm and that is exact this (i thought evojet said 2.5cm in the manual also). This has always provided good cooling and thrust. You measure this between the exit of the nozzle and the start of the real pipe, not the cone.

Very nice building report!

Keep up the good work :)

Thanks Felix :)

It has stood on it's own legs :) Even the living room is a bit small..... Sadly the wings do not fit nicely on the fuselage.... i will fix that later i hope.

The exhaust pipe has been aligned and the mounts are glued.

The tank has been build and the mounts are glued.

The elevator control is also ready.

as Mr. Höchsmann told me under 4 eyes the "S" on the bridge must in direction to the servo. This is a secret information and is not part of the building instruction.

What instructions? I only have a CD with photo's......

But i looked at the bridge and it looks identical up and down? The only reason for a specific position can be the direction from which the bearings are pressed in. I have added washers to prevent the bridge to fall off if a bearing fails. If there is another reason then please tell me :)

that´s the building instructions :cool:

i think this is the reason ...

First time on the field and it fits nicely in the car. During the build-up i discovered a flaw in the construction and will fix that later. It took a lot of weight to keep the nose wheel on the ground so i will be putting everything as far forward as possible. The good news is i can use a larger hopper than i hoped and normal LiPo batteries. It needs at least 2.5kg in the tip of the nose so keeping the weight down in the front build is not that important anymore.
 
Did you have a "normal" version of this F86? My last one needs no lead in the Nose to reach the correct CG...

This one was a "special" as far as i know. It should be a bit lighter overall and no work was done at all (no wood glued in the fuselage ect). It is a rough version straight out of the molds.

I don't know if lead is needed since most of the work in the rear is done (engine, pipe, elevator servo's and linkage is ready, only need to add the rudder servo and linkage, and the light) and the nose is still pretty empty. I will need to put in the nose:
- Intake tube
- Nose mount magnets
- Batteries
- Landing lights and mechanisme
- Hopper tank
- Ecu / pump ect
- Gear door and mechanics
- Tank connectors, switches, display ect
- Cockpit
- Air system

So i think those 2.5kg should be in all that somehow :) Other work like slats and main gear doors, wing servo's / linkage is closer to the CG and will have not much influence. Maybe a bit hopefull but with another 4kg is might be ready. It is now under 16kg i think (will measure accurately in a few weeks). I also noticed the tank looks a bit small compared to the manual so i assume this is the smaller 3.6L version (have to test) which is 3kg of fuel only. There should be enough margin to get it under 25kg with drop tanks and everything including a special effect :)
