They want to go out to play. Maybe tomorrow. Daddy needed a nap...

Nacelles added to Rolling Gear
I described earlier how I went about on a whim adding rolling tripod landing gear to my HK500, which I posted here. I noted I was working on nacelles to put over the head of the gear using wheel pants from my Eflite PulseXT 25e.
I finshed them, though one needs another coat of paint. I installed the starboard nacelle and am posting some pics because, honestly, it looks frickin' awesome!
The money shot! Sweet with both nacelles on. I test spun her with the blades slightly off kilter so there would be a start up wobble and she bounced on her struts a bit but was stable. Started her with the blades aligned, sweet balance. This was with 2x 3S 3000 mAh up front.
Will work on getting some video!

Tripod Heli Rolling Landing Gear Project
I have always liked the look of trainling link landing gear, and I have wanted to put a set on a heli since I first started modleing. A few months ago I found these trialing link landing gear at Hobby King, at a pretty hard to believe price.
I had asked on Helifreak if anyone had any ideas on how to put these on a 500 class heli, in this case my HK500, but no one had any ideas. I have been thinking about it for a long time, but the other night came up with this idea.
I used the nylon strut from a normal 500 Class heli and cut a slit in the bottom of the strut.
I opened this and pushed the landing gear through it.
Here you can see the way I fit the gear strut onto the nylon landing gear.
I used wire ties to secure the aluminum strut to the nylon strut.
You can see a touch of CA to further secure the gear.
I built a wood cross bar to secure the nylon landing gear strut to. I bolted the nylon part to the wood, and used servo screws to attach the wood to the heli frame.
I tossed on a couple of wire ties to push some of the landing torque to the frame
rather than just the landing gear screws. (Yes, I see the exposed connectors... will be taping them).
I built a wood brace to put some of the rear gear ooad onto the
frame since the gear itself is attached to the reciever tray.
Side view. I changed the screw that the gear is mounted to, to a longer
one to allow a larger spacer, extending the length a bit.
Here's a view of the change with a larger white spacer.
I mounted the rear gear just aft of the servo tray screws to put the loan
on the pivot rather than on the end, decreasing the torque on the tray.
The heli's weight sets the gear a bit on the springs, giving it a nice bounce and recoil. I think the tripod's footprint is a bit small, and I may need to move the rear gear further back. If I do I will need to develop a base a bit stronger than the nylon receiver tray.
I have a set of wheel pants from an Eflite Pulse XT 25e I am playing with to make nacelles for the gear tops. Could be pretty sweet!
Addendum: Added nacelles. Check out the pics here! I went back and moved the nylon strut in front of the wood block, effectively moving the wheelbase another cm forward and long. Not sure it matts, but it makes me feel better. I just couldn't shake the feeling the wheelbase was too short, almost cartoonish. Looks much better. I had to trim the ends of the spar.

I hate it when this happens...
Flying my Phoenix sim when I heard a "tink"... and the right gimbal lost its detente. I took the cover off to find to see if the gimbal lever thingy pin had fallen out, and it had. In fact, I couldn't find it. As I was putting the cover back on the other gimbal "tink"ed and went askew. Crap, both sides. Last time this happened I sent it to Spektrum and they fixed it, but this time its a few years old. They will likely still fix it, and maybe for free, but just as likely they might charge me this time.
Cross eyed gimbals...
Nav Lights on a my EXI 450
Bored last night, dragged out the damaged Tiny Bright Lights nave set I once had on a Walkera CB 180D. The red strobe wire was damaged a ways back, so its missing. These are among the brighest lights out there, but the company doesn't seem to be around anymore. Heard the guy got sick... Shame, they were affordable, tiny and bright, even if the wires were fragile. Decided to solder a Spektrum plug on them and plug them into the battery spot on the receiver.
The green does seem brighter than the red.
Port
Starboard, caught the white stroe on above the horizontal stab.
Two white lights, one under the carrige, the other on top of the Tarot FBL.
Rear view catches the two white lights. Purists recognize yes, you can see the port and starboard lights from behind. Maybe someday I'll care.
Crappy video, but you get the point. Made in iMovie which I hate...
