Test runs complete, just a few more details to add like anti glare black on the nose as I think this looked great on Steve's Airworld Cougar, then some alterations to the drop tanks and its all done. We've lost the use of this site for flying but thanks to Steve Johnson for arranging a couple of hours of ground tests. Its nice to photograph these jets on tarmac they look a bit odd sat on a field of grass. Its also a good idea to ground test a model where you cant fly it as it takes away any temptation to rush through the ground stuff.

Hi Craig, thanks...
I first applied a dark paint wash to the airframe rubbed it back to leave the detail. I then applied some subtle airbrush weathering layering the colours to create a little depth. Ive recently been on an airbrush course which was useful for me to improve and gain some understanding as I was self taught up until now. I'd reached that point of not being able to improve without professional tuition. I've also been on a composites course as I've got some cool mods planned for my new A4
Cheers, Alex

The pilot in his new home along with a few fibre optic lights in the instrument panel. The cockpit is a major hassle to remove so hopefully it will only need to be taken out once a year for maintaining the ancillaries installed below it.

Hi Bruno
Sure I'll take a few pics for you... but in the mean time I basically cut 4 oval shaped holes in the nose, tack glued the guns which are made out of plastic tube then hysoled the whole lot in.

Hi Alex,
Are you planning to do a build thread on your new A4 in particular the "cool mods" learned on your composite course
Will be starting the build of my new A4 shortly so most interested in your ideas....not planning a removeable nose like the Cougar's are you? be great access on the A4.
Cheers
Rene

Nice Cougar Bruno.
Hi Mike, you can find all my videos on my youtube channel here: http://www.youtube.com/user/TLJC1
Hi Rene, That thought did cross my mind but I'm going to focus heavily on weight reduction on my next A4 so splitting the nose will most likely add weight. There will be no speed brakes, the 180 will be replaced by the latest generation 140 from Jets Munt which is light, powerful and very frugal. The main Mod will be slats, these will be moulded from prepreg carbon and cured in an autoclave while all the formers will be carbon along with the leading edge under the slats, I'll be using prepreg carbon which will allow me to make extremely strong and light components.
Cheers, Alex

I thought I'd mention this photo as a few people have mentioned the model looked a bit skewed and it does... I didn't notice myself until I posted the photos which is another good reason to do these builds online and on my Facebook page: https://www.facebook.com/TheLittleJetCompany?ref=hl
The left tire was flat and the right oleo a little stiff which doesn't help but I thought I'd look at it again. The nose cone doesn't locate to center so I'll take a bit off the slots and it should cure it coupled with the other bits. Thanks to everyone who pointed it out and if you do see something that looks a bit odd please post it as I wont be offended.

Mechanical UP valves really good and very reliable.

Theres a few little jobs left to do but its mainly finished.

You can see the UAT when you take the nose off as I always like to check for air after each flight. I had to change the nose gear rams to UP rams as the two from Skymaster leaked. They are the best rams you can buy in my opinion.

Hi Alex,
Nice fit out. Did you use acrylics or oil based paints for your wash?
Another question....I am not familiar with the functioning of the UP gear and door sequencer. How do you achieve the required delay in timing....does it just rely on the tuning of the needle valves in the valve block?
Thanks in advance.
Craig.

Hi Craig
Yes, I use any water based paint I can get my hands on, I just thin it to give the desired prominence of the final wash. Then highlight areas with the airbrush.
Yes you just adjust the needles on the valve to change the timing the second valve is needed to keep the nose gear doors open instead of closing like the main gear doors.

Thanks Anton.
The install has now been finished with JR DMSS X-Bus running though v02.2 Royal SRS software. I'm just waiting on another JR 731BX receiver that I'll position in the fuselage and she's ready to go with the JR XG14.
Thanks to Dave W at Motors and Rotors who helped me with the DMSS stuff.

Hi Guys
Can anyone help...
The instructions say set the CG 245mm from the leading edge, what point did you guys measure it from? The wing panel leading edge, the intake root or the end of the intake? Theres a good 60mm difference so I want to make sure I set the CG in the correct location.
