Here's one thing, the parts bag for the wing has six sections of brass tube in it. No mention of it in the manual. I'm telling myself it's to be cut to the appropriate length and make sleeves over the slat and flap pushrods between the clevises, but with no mention and no pictures showing that, just want to be sure.
I also need the addendum addressing the early kits with the flap control horn recessed too far. Emailed CARF early last week but haven't heard back just yet.

Hey George,
Jump on Facebook and check out Intaircos page. Peter Agnew has a build log on his SU with VT. I think he opened the petals on the tail cone to fit nozzles inside cone.
Pete has done a sensational job customising the plane and is manufacturing a lot of special parts for it.
Well worth a look.
cheers

Does anyone recall if the speed board mount brackets and hardware were included with their kit? I don't see them in the one I've got - not a probably to make something, just curious why that would have been omitted given the quality of the kit contents.
I'm waiting for updated gear parts as the kit I'm building has the defective pivot block which causes the axle hub to hit the fuselage skin on retraction/rotation. But the gear leg also contacts the fuselage side with gear down as well, though the new pivot block may correct this spacing too so I'll wait and see.
In the meantime I need to sort out brakes. The gear kit was ordered without the standard DuBro light wheels, and instead there are some mega-heavy solid rubber w/aluminum hubs wheels included. I want to ditch those and go with the light DuBros, as Andreas says they hold up great even after 100+ flights. Plus with the printed hub covers, the look will be just fine. But I'm not sure if the brakes I have are correct and/or compatible with those wheels. Is the rubber brake drum literally just pressing against the plastic hub of the DuBro wheels? Anyone got good detailed pictures of their gear setups?

I dont think they will ever get it right..just care only that gear is locked and in correct angles when is down.
Cut axle hub if interferes when its up ...
...regarding the Dubro tires..if one will brake away you might risk crashing.I end up making my own

I did read about your gear troubles, but looking at your pictures that is most definitely not the same gear that I have with this kit. Could be both sets were built by Matrix, but the bracket is not at all the same, nor are the linkages. Also the air cylinders in your gear, and the gear shown on Matrix's website are behind the gear - in my set for the CARF SU-27 the cylinders are forward of the rotation point, and underneath (well, technically above) the gear leg when retracted.

I did not use these Dubro wheel or these really terrible brakes. I think they are a rip off. Besides how on earth you let a jet roll at high speed on a runway with plastic wheel rims? Jet wheels should have ball bearing equipped rims.
I made a set from Behotec with Behotec brakes since the mains axle is 6mm and used the Intairco nose wheels since the nose axles are imperial and not metric.

I am going to install the Dubro wheels. Yes it feels wrong, but I'm going to take Andreas' word for it.

I think the wheels I have in a box must be Behotecs having looked at them online, but my goodness are they heavy! Have you flown yours yet and any trouble with the gear retracting? All that weight moving against the airflow including a 90 degree rotation has got to be a lot for the air cylinders to handle.

those will be good too I think if they are not to heavy and thinner than dubros 5,5 you'll have enough room to fit when retracted, I think the guys from Intairco are building one with 5' Robart's...

Hey Mike, PITA.....the trouble is getting the residual air out of the lines near the cylinders. No matter how hard you try there will always be a little air in the cylinders that comes out with repeated cycling and in long runs it will just snorkel up and down the lines from the cylinders. I will install a T fitting nearby to bleed off that air but the whole process is very messy. Air all the way unless you absolutely have to go oil IMO.

Guys who are flying this model already, do you have your service items (switches, air fill, fuel fill, fuel shutoff valves) all accessible through the nosecone or do you raise the canopy and remove parts of the cockpit between flights? With no hatches around center ship, been trying to figure out how to lay those items out without creating unnecessarily long runs for everything but there may not be any way to avoid it. As of now I'm looking at having probably 12 or more feet of fuel line per turbine when you consider going from fill port in the nose to UAT near nose gear, then back up front to a shut off valve in the nose before going back to the pump and then turbines.
I have not yet started on the cockpit - once assembled can it be easily removed to access fuel shutoff valves and such if I were to install them around the nose gear mount instead of at the nose cone?

I have the fuel shut off valves and fuel line under the speed brake unfortunatelly I don't have pictures of that at the moment, switches pwr box screen and air lines in the nose, the cabin is not easy to open all the time, unless you make some modification.. I have a 1/6 pilot made fromm Taylored Pilots
