Hi
I’ve been informed that the "twin turbine in the tail" version F18 was no more produced by Skymaster.
Do you know why ?

Very strange because this was writen in an email of John from Skymaster on 24th october :

"Anton strongly suggests to order twin version in the middle.It is much safter than engine at tail.We now stop to make kit with engine at tail. "

However, it’s a good news as my next F18 will be (if possible) with turbine in the tail.
I already lost my plane due to a supposed engine fire which burnt elev servos.

Yes, it was. I had just repainted the fins and improved its weathering.
I was in love with that plane.

Hello Arnaud, I am sincerely sorry for your F18, but as I understand that you intend to buy a new one, I guess you were very happy with it. I would like to ask just a few questions:
1) is it true that the oléos of the main landing gear are fully compressed when the plane is on the ground and if yes is it a problem ?
2) What would or will you change during the building for the next one?
3) Do you think a single turbine version would be Ok ?
Many thanks and best regards.Etienne.

Hi Etienne,
No problem with oleos. It taxis like a Rolls Royce.
You can pressurize the oleos as you wish. At 12bars, the gear is fully extended, even at MTOW.
You can chose the attitude of the plane on ground with the air pressure.
For the next one, I will move the position of the turbines fully aft to be sure not to damage the plane in case of an engine fire or hot start.
Aside this, I was quite happy with the initial choices for my first build.
Single version would be OK for sure. But you loose the redundancy and the sonority of the twin engine version and need a bifurcated pipe.

Anyone care to share some pictures of how they did the flap and aileron rods? Thanks

Arnaud I’m very sorry to hear that mate. Make sure you order soon, Skymaster have long delays. I ordered mine over 7 months ago and still no sign of it being finished. And I’m not getting a full paint job either

Any idea what caused the fire? Pipe collapse?

Arnaud what turbines were you running? Did they have auto restart?

Hi
Auto restart is no help in case of engine fire.
And don’t know exactly what happened.
Jeti telemetry confirmed engine trouble just before the fire.

I’ve seen a few jets lost because the auto restart function has started the fire. For example fuel leak leading to flame out, then the auto re start kicks in and lights it up. With a twin you wouldn’t hear this happening as the other engine is still running.
Anyway Arnaud I’m sorry again for your loss mate. I’m sure you’ll bounce back.

Cheers
Levi

That said I saw Barry’s F18 have a flameout and auto restart saved it... also saw Franco have a flameout and after coming back around it was restarted and he continued to fly and land safely. It can go both ways.

Yes Gunradd I’m sure it works both ways mate. I’ve only heard of losses with auto restart though. When a turbine stops it’s usually for good reason. I thought you lost that cool looking Hornet of yours due to adverse yaw caused by RPM interference between the turbines? Did one turbine end up flaming out?

Well your right restart would not have helped me probably. I did loose it with the RPM interference. The one engine flamed out but the ECU thought it was still running due to it picking up the RPM signal from the other engine. After my maiden I had a flameout and was able to land it. I could not figure out why the ECU showed user off instead of flameout.... User off means I commanded it to shut down. Engines are hooked together with a Y so both engines are getting the same command. Finally figured out that the left engine would read the right engines RPM. The ECU would reduce pump PW because the RPM was 2 times higher then it should be. It would reduce fuel flow down to the point it would flameout yet the ECU still thinks its running due to the RPM being where it should be. Still even with all that if the engine alignment would have been correct I would have been able to save it. From what I hear they are still shipping them with the mounts at different angles so the engines need to be shimmed to get the correct angles. Mine and 2 others I have seen had the angles different between the left and right engines. Skymaster should really build that part in a jig with the correct angles because of the way these engines are installed and that fact they are so far from the CG it has a huge effect if the angles are not correct. Its a shame its a great looking aircraft but they don't seem to live long. For what ever reason the C model seems to die faster then the EF models.

Thanks for sharing your experience Gunrad. No doubt you’ve saved many of us having the same issue.

cheers mate

I received my F18 just before Christmas and I’m happy to report that Skymaster have listened to everyone and fixed the issues with this jet. I got Skymaster to install all servos due to the difficulty people were having with the flaps especially. I was hesitant to do this as it’s a big deal but they have done a great job. Flaps are smooth as silk and go all the way down, so are the elevators and rudders. I have to do the ailerons myself as the Futaba 177 servos I supplied wont fit in the ailerons. I will replace the little gold clevis’s as I don’t like the fact that all the load is on that little pin. I also had Skymaster apply a base coat Grey to the model. That way they do all the sanding, filling and prep. I have the paint, decals, masks and clear coat ready to apply myself I haven’t started work on it yet so something may pop up but at this point I could not be happier with this model. Thanks John and Anton.

Mid-mounted or Rear-mounted engine setup?
Been watching this F18 for a while and been waiting to order one but not until they get the manufacturing problems figured out.
Could you post a few photos of the interior construction?

This guy added thrust vectoring on his. Awesome flight.

Thanks, Tom

Tom then you will never own one, they will never fix their issues and history has shown that. I will post some pictures of the interior once I start building again.
