That's what I call any foam airplane these days. Beer cooler with a motor! I'm sure the SH will hold one of those Fosters Mini Kegs!

Here's another video from the SH. Today I was testing out the new 5.8ghz TX I picked up about the same time the SH showed up. After adding the TX to the SH I ended up scooting my battery back about a 1/4". I could probably stand to take it back some more. At this rate the battery is moving pretty close to the CG of the SH.

Skyhunter 3 views... (0 min 58 sec)


I have more OSD video I can post, but it's pretty dull..

Is you CG at 95mm? where the servo wires lay in the wing?

It's about a finger tip away from that line. I'll probably move it back to that point the next go around. Usually I feel for that spot then move forward off the ledge.

lol.
The question was not a joke. I'm just wondering if there's any point in painting/covering these black EPO planes. Temperatures here average 30C in summer. I know ESC and bec will be burried under the foam so they ll be insulated, but what about the gps? Also woried that the plane itself might become more flexible.

I wasn't joking either. Temperature in the place where SH is designed and produced (and test-flown) in summer is often well over 30, plus 90+% humidity. Temperature in the place where I live is generally over 30 May-October, last summer was quite some hell with 35+ for a few weeks in a row, 90ish humidity. Pilots sweat, planes fly. Haven't heard of any crash due to overheating.

Glad to know. Painting black foam would be time consuming

Two things.
1. You've got a ghosting artifact. If using Sony Vegas, right click on all clips, and select
Switches - Disable Resample. Otherwise make sure project and render
frame rate, matches source clip frame rate exactly.
2. The view is shaky as though there's constant vibration, but I don't see the usual
jello artifact. Rendering glitch?

For whatever it's worth, CG at 93-95mm doesn't feel "on the edge" to me at all.
I am a bit puzzled as to why you're having to move your battery back so far to get there.
Mine is still a good distance forward of the CG and I've got flight camera + pan&tilt
and gopro on pan, all ahead of the CG, and my tail group is further forward than yours.
You carrying some other brick in the nose?

Good to know on the Vegas stuff since I just switched over to it. By what I ment with 'on the edge' is on the edge where the servo wire cut is at. I'm on the edge of cutout. Should have been more specific and just measured it. The brick I'm carring is the cased GoPro. Having a 6oz brick vs a 3oz camera in the front doesn't help. All in good fun!

If you want more time to align, use the stock contact adhesive.
This fuse locks together really well (lots of little alignment tabs and dimples), so
I didn't have any issues getting it aligned in time with thick CA. The kicker is applied to
one side and left to evap for a few minutes, then thick CA on the other side, and
press together.

What glue are you guys using to join the wood motor mount to the fuselage? thx

How well does it transport? I have a twin boom (not removable) and it gets cumbersome.

Here is how I transport it.
The holder turns into a stand when I flip it over

It works great. I use the same Velcro strap for storage over the nose and also when I have it on the stand for assembly and preflight testing. Stand/holder is only 19" tall and it protects the plane. Especially the tail section.

Great holder Mark. Can you give us specs on it so we could build one?
