Hi
I have my -10 project on a dolly and am planning to get it up on its wheels in the next couple of weeks.
I have the tail cone (but not the feathers) attached and am wondering how tippy it will be if there is no engine attached.
Any comments? If I need to add ballast to the nose till I get an engine, is there any preferred way to do this?
Cheers
Les

It’s not tippy side to side at all. You need to prop the tail up until you get the engine on. You would need several hundred pounds on the nose to hold the tail up in a stable way. I would just put a stand on the tail like in he attached picture.

Hey Les,
I needed to maneuver the plane w/out wings or tail feathers in and out of
the shop during painting and w/out the engine. So I lashed two 5 gal. jugs
of water onto the engine mount to counter the tail. It was just enough so
that I could push down on the tail to raise the front wheel ... easily
steered it from the tail. Used a small prop under the tail tie down so
that I could temporarily install the vert and rudder to tape off stripes
matching the fuse.
Later, - Lew

Guys
Thanks for the info. I'll likely install bump bar in tail but use the water in pail trick as well.
Cheers

Well, if it isn't one thing it's another. Last week my Garmin 496 GPS died,
this week it's my HID landing lights. So I'm going to replace them with
LEDs. Vans sells a Sunspot LED wing tip kit for the RV10/14 kits. From the
picture I can't tell if they are a exact replacement for the original RV-10
wing tip landing light or not. Vans picture doesn't show the position lights
that the original installation has in the wing tip. Maybe there is a better
LED light available. Wouldn't mind installing them inboard from the tips for
better center line coverage. I've considered an additional light under the
prop for center line coverage. Tried mounting one on the front wheel pant
but too much vibration for a filament type lamp. LED should be ok with
vibration though. Any landing light suggestions?

I can't comment on most of the things in the email, but
I can tell you that a bit over a year ago I bought a set
of HID's on ebay, brand new, and the pair of them with
ballasts was about $110. So, if you do end up wanting
to replace your HID with another HID, the cost is
probably much less than your original purchase. I think
I paid $400 each back in 2005, and now they're more like
$110/pr if you find them right.
I'm assuming your HID is mounted in a wing cutout.
You should be able to find an LED that will fit into
that spot too, but you'll spend a bunch more...but you
can get a real good light too.

Just leave the pail of water outside overnight and you will have a solid weight. ;-(-sent from the I-droid implanted in my forearm
