Got a delivery from Dreamworks today, so I got to do some more work on the xXx. Focused on landing gear today since I got a set of Pro-Link main struts, Intairco main wheel hubs and brakes as a part of this order, that meant I had some work to do getting the struts modified a bit to fit into the wing. Not too involved, but I had to cut off 15mm of the struts to get them short enough, before cutting I had to chuck them up in the lathe to extend the 1/2" dia. further down the leg, see pic for details. After that was done it was a simple job of cutting it and installing it all in the plane. Fit is pretty good, next up now is getting the gear doors hinged and installed, then it's more waiting for parts, namely getting the Lado door actuators to finish up the gear install. I also got the last missing pice for the nose gear, a steering arm so I also got that done.

Nice work on the gear Arngier ! Good to have some trailing angle in the mains for those hard landings Have you done any fitting of your Fan tail tube ? It's looking like the horizontal stab tube may be in the way if fan tube is sized to match exit opening ? Not an expert on E-flux calculations and have always just sized my exit to match fuse. I want maximum flux on this baby though. Any recommendations ?

tube

Hello Paul,
The tail fin mount is not in the way of the tube.
I have installed a dual wall turbine tube and it sits perfectly.

Paul,

exit diameter on the fuselage is much too large, even for my 5" Ramtec fan. The exit dia. is 105mm, and I will go for 95mm with this fan, well a bit less as it needs to fit inside a 95mm ID burner ring.

Finished up the main gear doors, and ailerons on one wing last night. Will post pictures later. One thing to note: Offset hinges will NOT work. Onlt piano style will work.

Yup, i have also come to that conclusion on the main geardoors, I wish JTM had put the hingeline a bit further out from the wingroot so using offset hinges would not be such a problem.

Got my Lado E-Doors today and have just got the nose geardoor actuator installed, I made up a pair of brackets from 3mm plywood which has been glued with Hysol. Also spent some time tinkering with the programming card, and once I got the hang of setting them up it was a breeze. My plan is to have the inner main doors close again after the gear is out and setting this up was pretty easy. No need for a sequencer, once they have been programmed they plug straight into the Rx.

Arngeir - Thanks for the tip on the fan exit tube diameter and the main door hinge . A burner ring with some vent holes would be good for airflow around the tube as well. I'm still planning on mounting my ESC top side of fan adapter - any more thoughts on cooling vents ?

Nice action on your nose gear - thanks for breaking the dead spell on this string. I'll probably have some updated pics for you guys Monday. I've done enough cutting on the fuse etc. to find that the paint adhesion is much improved on this jet over past JTM's I've worked on - no longer an issue. I've also mounted my tail servo's and it looks like the design intent is to mount the servo's to the fuse and put clearance holes in the stabs - which is what I did and it works great. Quick too - no mounting blocks to glue in etc.

Cliff,
That looks good with a turbine, for reference my Stumax 110 xXx weighs in at 17 pounds with batteries, right in the middle of your loaded vs. landing weights, couldn't ask for better. I'm still resisting the urge to put my Wren 100 in my xXx but then I fly her and the power of the Stumax keeps me convinced electric ain't so bad, just lacks the smell of power.
