Since the other thread went way off course, I'm starting a new thread. Please no comments about AMA, or waivers, or how advanced, or certification... they can be addressed at the when they are needed.

My F-18 Twin:

Diamond Back Scheme
Factory Installed Light Kit including scale lights on the aileron covers
Standard version with Manual canopy (not air operated)

http://www.youtube.com/watch?v=sHyuI...ature=youtu.be

Servos:
4 x HS-7950 Servos used on flaps & rudders (Speed set to 36 to match the HS-7980)
4 x HS-7980 Servos on Elevators and Ailerons.
1 x 7955 for Nose Steering (may change this to a Hs-7950 depending on the performance)

Hitec servos are great and include a blue aluminum arm that can be used on everything except may the flaps, for that you may need a 1" SWB arm. the HS-7980 is a hauss of a servo making 611 torque, this will be needed as the latest generation of the F-18 only uses 1 servo/elevator and 1 servo/aileron.

Servo hardware:
50 Ft spool of twisted wire form Servocity for making custom extensions: http://www.servocity.com/html/servo_wire__bulk_.html

2 1/6 scale pilots I got fro ebay, total cost was $115.00 shipped, they are pretty good and have a lot of accessories.

Engines:
Dual Kintech 170G turbines, to be run on Diesel from day 1 with Kingtech Turbine oil, combined output of 74lbs of thrust (37lbs each)

Retracts, possible Hydraulic conversion for BOTH the retracts and the rams:

If not than $750 down and locked conversion, people that have this jet seem to raise concern over the stock air retracts so this is something that would need to be addressed.

Disco,
Great info on the components selected to finish your F/A-18 Horner twin.
Keep us posted as to the progress of this jet.

I haven't decided on the power controller, I'm leaning towards the Powerbox Cockpit SRS: http://www.powerbox-systems.com/e/po...-srs/start.php
and 2x Futaba Sbus Servos: http://www3.towerhobbies.com/cgi-bin...?&I=LXBPKP&P=3

Guidance will be provided with a futaba 18mz.

My jet arrived, but there were some damages, not major but it will be 1-2 weeks before they are fixed, until then the build will be on hold.

Issues:

1, No Horns included with the hit or on the flaps, so Installing servos is on hold.
2, Flaps didn't have the cut-out or the horn, FEJ is supposed to be sending these
3, Missing light controller, was in the video, but not included.
4, Paint on the covers doesn't really match the plane

Pros:
Light kit install overall was pretty nice and only $295.00
Weathering on the plane was provided at no charge.

More pics, note: the air brake was supposed to be installed, but broke off during transit, so I'm wondering how strong the glue is on the rest of the plane.

In case people are wondering of the cost mine was right at about 6.2k without the ordinance kit but with 2 wing tip missiles.

That sucks about your shipping damage, hope james at fej takes care of that, I could not get any help on some issue with mine.

I really like the CAT, I have one as well. Really concise and will be a good match for a twin setup.

DiscoWings

My Feedback: (76)

yeah kingtech has a some new airtraps coming out for just $40.00 I think they are made form air power but they are the flexible kind. People have said the soft tanks don't do well on high power turbines. I have about 4 of these, you can't service them but they should last for years and years.

If you using futaba and 6014 receiver.  I use the orbits from sin city jets instead of the powerbox.   It works great and cost only $100.

I've never had a problem with UATs, but I'm using CATs in 3 planes (2 twins)... I like that they can be mounted horizontally and are completely enclosed.

This is going to be nice. thanks for posting your supply info!

currently repairing the fuse cracks using stuff from a body shop to fiberglass the inside, Fly Eagle Jet sent over the matching paints with the thinner so hopefully by the end of the week I"ll have it finished.
I'm really considering doing this hydrolic conversion it seems cheap and straight forward and should add some more power to the retracts.

Dont waste time using the paint the hardener will drys up fast

I got a question fro X3dflyer:

Ok my reasoning for this is, I don't see my self deploying flaps at high speeds, I just need a servo without enough power to keep them in place the 7950 puts out at least the same amount as 8711 so I should be good in that regard, these servos I will only slow down for my own taste not really needed.

For the Rudder, I went with the 7950 because they are 2 servos 1 for each rudder and I don't think you need that much, you could possibly go with 2x 7980s on the rudder also, I might do this too... But even the original F-18 which was much heavier only had a provision for 1 servo/rudder and it flew fine I don't think the F-18 does knife Edge all that well so I don't see my self using rudder on anything else but landings and may be on slow turns. I will probably program the 7950s to match the speed of the 7980s just keep the surfaces moving the same speed, I'm sure this doens't really make any difference and is just something I want to do for the sake of doing it.

The elevators and ailerons are the surfaces that need the most power hence the 7980's for them 611 should be enough.

Will counter balance the elevators when I get home, I got a bag of Steel power from the classifieds, I'll mix this up in a paste with some 30 min epoxy and inject it into the tip of the elevators, should only need about 5 oz / elevator to counter balance.

DiscoWings

My Feedback: (76)

So today I counter balanced the elevators, I have talked with Rex and he said to definatley do this. Although his method is different than mine both achieve the same result.
I got some STEEL Power off the rcu classifieds and used it as my weights.

Here is what I did:

Step 1: drill out a 5/16th hole in the stabs.

Step 2: Pour some of the steel power into a mixing cup, I used 50% steel power and 50% epoxy. It took 2.5 cups full of this mixture to balance each of my stabs. I used 15 min epoxy for this and also used some denature alcohol to thin the mixture.

Step 3: Pour the mixture into hole with the stab pointing down, leave the stab and let it dry.

Step 4: After 15 mins hold and test the stab in your hand to see if it is relatively balanced, it doesn't have to be perfect just close enough.

Step 5: Once its balanced its now time to fill up that hole you made

Step 6: I used BVM milled fiber and 15 min epoxy to make a very thick filler, it was about 2/3 bvm milled fiber 1/3 epoxy. This makes a great filler and is easy to sand.

Step 7: Fill in your hole and let it dry

Step 8: Sand the whole thing smooth and use some of the paint that came with your kit to cover the hole.

Step 9: balanced stabs! Servos should not have to work as hard keep the plane level.[8D]

Great job! Just make sure you have a little bit of "weight load" towards the front or back so the servo won't "jitter" to find center. This happens when the Stab is close to or on true balance.

Rex

DiscoWings

My Feedback: (76)

Yes the stabs are every so slightly nose down (up elevator) so the servos should be happy.

dubd

Nice job. The next step is for the factory to do this before future customers receive their plane.

DiscoWings

My Feedback: (76)

Yeah I'm not happy with the factory, still haven't gotten my HORNS for the flaps I wanted to start on the wings but can't until they send me the horns for the flaps...

rbxbear44

My Feedback: (86)

If you are doing the external Pushrod and Control Horn setup, I have a bunch of CF Horns I can send to you today. If internal, I do not have those. Let me know...send me your address via email.
