Now take 4 bolts for mounting the engine and use security rings under the bolts !
Take the spinner backplate and the little insert ring from Tru Turn.
But first mount the enclosed 0,6mm thin plywood ring to put between the fuselage and spinnerbackplate.
Mount the spinner backplate and use the ring and nut.

look

Now tape the spinner backplate and the 0,6mm thin plywood spacer tight to the fuselage with tape:

look

Now it is important to set the engine straight at 90 degrees in the fuselage !! Keep it secure in that place and apply some ZAP green drops on the firewall sides where it touches the fuselage. Be carefull and do not use to much ZAP green.
Let the ZAP dry and do not use accelerator because you will get a mark on the fuselage because the glue shrimps and pull the fuselage at that part inside. (Ignoring builders can use a filler for reparing the damage but before using a filler sand the fuse with 150 gritt.)
When the ZAP is dry use UHU plus on the back of the firewall and put away the fuselage let it stand straight up with the nose down and secure the fuse with tape to your working bench, do not use the dinner table because it has to dry 24 hours !!.[>:]
A day later take the fuselage and remove the engine and glue the front of the firewall with UHU plus.
Again let it dry for 24 hours with the nose up and secure the fuse with masking tape.
When dry apply some epoxy on the firewall ( on both sides but not in one day) to protect it against fuel.

Now I have to do the job again because I have used the fuselage out off the old mold. Tomorrow I will use the new fuselage.
First I will wax the mold and PVA for making a new fuselage for Robert.

look

All clear, any questions ??

look

Nickos, its time to make a few holes in the sky !!

Look,

You make a mistake, not for robert but for Nick !!!
SeeYa speedflying the day after tomorrow! HIHAAAAAAAAAAAAAAA
Later

See pictures:

I have noticed that it is better to mount the Sullivan cable in the firewall before glueing the firewall. Later it is difficult to get the cable in the small hole or drill the whole a little bigger. I have made a new template and made a new cut out in the fuse for the engine.
I have cleaned the fuse on the inside with water to remove all dust. So tomorrow I can glue the firewall.
Sorry Nick no kit first is Robert. The mold has been waxed an one layer of PVA. So a new fuse can be made.

Look,

You are going at a pace that shames most of us completely. If this is slow, fast must really be something to watch! Take care of yourself first, no model is worth wrecking your body for. If people complain about that, then you really don't want them as customers and I would hope they find a different hobby so they don't bother the rest of us with their attitude. After all, we are only talking about toy airplanes here.

Mark, thank you.
Look.

Now I am mounting the firewall in the newest fuselage. All fits well so I can start glueing the plywood to the fuse.

Has anybody experience with an upside down engine that you need rudder ?
I prefer to build a model without rudder. If necessary I will build a working rudder.
Please advise.

I prefer a rudder on all of my racing aircraft.

Absolutely essential on the QM40 aircraft. Without it the plane will simply make a hard left when released for launch. Same goes for the Q-500 aircraft.. that v-tail mixing helps a ton.

The take-off torque demands right rudder if one plans for the aircraft to travel in a straight line as the plane climbs out and gathers speed.

look

OK, then I will make a rudder.
I do not want troubles with the first flight.
Thank you.
So that will be the next job after glueing the firewall.

Look,

Back in post #54 the second picture shows some type of hobby plane. Can you tell me who it is made by, or where someone could find such a nice little tool.
I have seen one before, and if it is the same, it uses disposable razor blades.

Thank you

Julian

I have one very similar to Look's, you should be able to find at every self respecting hobbie shop.
It's a very common tool for our hobbie, and like you said it uses disposable razor blades.

Cheers,

Not trying to hijack this thread, but the one Look has is different. His accomidates 3 positions for the razor blade.
Remklep, I have the one you posted a picture of.

look

My razorblade tool is from David. Is has no razorblade but thicker steel and very sharp. This tool works very nice

look

At the moment I am not complete satisfied with the firewall. In sharp corners of the fuse I always use cotton to avoid airbubbles.
I will give the firewall at the bottemcorners a bigger radius. So in 5 minutes I will start changing the CAD drawings and cnc cut the new firewall. That is better for a good fitting.

look

You only can buy the David tool in a good toolshop or try Google first.
Succes !! When I ship your kit, I can buy one for you and the new tool can be in the box.

look

I have made a new template for cutting out the engine. I have uses now the newest fuselage. When glueing in the firewall taker your time because it is an important and secure job. If you have to leave within a few time do it another time. First after the engine is complete lined out and you have used the spinner template between the fuse and the spinner and the spinner backplate is secure taped to the fuse. Put some drops of ZAP green in the fuse on the firewall outside. Turn the fuse in your hands and look on the outside how the ZAP green devides on the firewall and the fuse. Let it dry for an hour and mix the UHU plus 24 hours GLUE.
Take a stick and put some glue on the firewall and fuse, take the fuse in your hands and let the glue turn around on the whole firewall borders ( I do not know the right name). Protect the engine with some paper and tissue. Turn around the fuse several times,
the best is till the glue get gelated. Take a look several times for an hour ore more and put the fuse on a block of wood. Again take a look several times. Normally I place the fuse upside down but this firewall is open and the glue can run in your engine. See the last picture for the best position. Do not use too much glue but glue it well.

look

The next job is making a new fuse tomorrow and when ready I will cut of the tail (rudder) for making a rudder with hinges.
First I will draw the rudder for making a cut at the right place.

look

The UHU plus sticks on everything and pulls 600 pounds (300 Kilo).

Rudeboy

If you bake it in an oven at 180°.

Hardened at room temp it only holds about 150 kg/cm².

look

I think it is enough. [>:]
