I'm building an Astro Hog, and noticed that it doesn't call for any
thrust angle offset, or any firewall down angle, as I have been used to
seeing in other planes that I've built. What is the reason for this? Is it
because it is considered an acrobatic plane?
Also, is the ***really necessary on an OS 70 FS? Fellow club members
have said to ***it like I do my 2-strokes...by a finger over the
muffler outlet. I'm trying to get the engine further back against the
firewall, and removing the ***allows me to do this. Any reasons why I
should not?

p.s. The Hog is a single wing, not a bipe.

Hi Lynn;
I have the Hog Bipe. My fuselage did have both lateral and vertical
offset built into the firewall mount. I would have thought that the Hog
would be the same. I would trust the kit though as a friend of mine used
the same engine as you are using and as far as I know, he built it
according to plan and it flew great with lots of power. Happy Flying!

Oh, I forgot your second question. I have three os four strokes of
various sizes and have never used the chokes. As a matter of fact, I
removed them. A tiny bit of throttle for start up does the trick.

As I remember the plans for the Astro Hog,the wing and stabilizer
are set up at a positive incidence this would give you the same
effect as putting down thrust in engine.I would put a small
amount of right thrust in engine.

I've built both. They are completely different planes. I understand the
only two things common between them are the headrest and the name.

Lynn,
I have the Same setup. The .70 is a perfect match. I don't use a ***either.
Just spin the engine over a couple of turns with the finger on the muffler.
Get it wet. Then it easily starts by hand. You're gonna like that plane...:)

Thanks,

Many Sig kits do not use angled thrust, and they seem to fly fine. > Also, is

The finger over the exhaust method will work fine.

Many thanks to all who responded. The ***is gone, the engine is
snuggling up near the firewall, I've flip-flopped the carb, then put it
back again with the throttle arm on the left (looking for the best
throttle cable arrangement), and the work progresses...thanks again.

Lynn
