I happen to have that plane. I had a TT61Pro on it until I knocked the
firewall off by hitting a brick wall(don't ask why a brick wall is next to
the runway). It did not have unlimited vert. It is a heavy pane.
There's
no way that Zenoah 20EI is going to fit, and if it did the weight would be
too much to fly! The least weight for the power is what I want. Maybe a
Webra speed 55 with a pipe? I have a Webra speed 50 that I really like.
As
a matter of fact, when I hit the wall I had attached a beer can pipe on
the
stock muffler front half. It looked cool but it was too small of volume
to
work right.(ever seen those Bud aluminum long necks?)
Just put an OS 60 or TT 61 pro and go fly.

Yes, that's right mk--you discussed the weight/power issues of the
20ei in my Ultimate thread. I'll scratch that one.

Do you think a 90ish 2-stroke that will fit a 60 mount would be
overkill, simply unnecessary, etc.?

many 90s don't weigh much more than a 60, prop clearance is an issue. I
have thought about it on mine. I was given a Magnum 90 and I'm not sure how
it runs. Anyone know if there's a 3 blade prop for a 90 size 2cyl?




The SH is a heavy plane. It is interesting to note that the sheeted
foam wing on my late Lanier Stinger 40 weighed more than the SH's
wing. Maybe the excess mass is in the the SH's blocky fuselage.
Maybe some mods....

The Stinger 40 was a dog, at least with an Enya 45. My best planes
were probably a Spickler Q-500 with an OS 46FS/Mac tuned pipe, and a
good old Goldberg Eagle II with a modest OS 40fp.

I put a Fox 74 on the Eagle II which worked very well, but required a
brick in the tail to maintain the CG. Forgive me for going on a
bit....it's all coming back to me.

Please go on, that's why we're here.

My landing gear is very firm and short.. I bet I could save a little weight
if I used some glass filled nylon landing gear and foam wheels instead of
rubber.
I also have a Stinger but 60 size, not built by me. It is very heavy.
Due to mushy ailerons(bad servo extention) and no guts I haven't flown it
yet.
