Ya Mike,
I had the same thought. I watched the airspeed build up very rapidly
and then a very rapid pull out on recovery - having aerobatic
training and owned an aerobatic airplane (Citabria), that caught my
attention.
More for grins we actually had a G-meter in our FireFly - my partner
wanted it. He paid for it, I had to squeeze it in along with large
EIS, large diameter airspeed, and altimeter and a small electric
variometer (VSI). Do you have any ideal how small the panel space is
on a FireFly. It was fun to watch the VSI on climb out and try to
get just right speed for max rate climb. It was also interesting
what G's you encountered in that airplane. It was like a little red
sports car.

Why not install a poor mans auto pilot - a light bungee cord
(1/8-3/16" dia. cloth cover elastic bungee cord) with a half hitch
looped around the stick. Position the bungee so it crosses the stick
so it holds it in it's near neutral in flight position. You can move
the loop right or left to adjust wing level - if it at a slight
diagonal you can use it to adjust slight amount of stick forward or
stick back pressure. We had one on the FireFly worked great.

Subject: | Fw: Steel Gear Legs |
Thanks again for everyones input, the legs are finished and at the
powder coating shop, here is how it went.
Bought two three foot long pieces of 5/8" hot rolled steel rod this
morning. ($1.10 per foot) Found out they did not fit in the axle tubes
so I went looking for my belt sander to reduce one end of each.
Recalled a buddy borrowed it a few months back and since he lives 20
miles away and was at work I had to make do with my disk grinder and
than cleaned the ends up by hand with a couple belts from the missing
sander. Two hours later I had what I could have done in 5 minutes with
the sander finished.
Inserted the rods so they almost touched in the center under the
fuselage, taped the rods so they would not slide in and out of the axle
tubes, had the wife hold one gearleg in to the factory line while my son
held the other. With the tail wheel blocked up about a foot I C-clamped
a flat 1/4" thick aluminum plate to each rod making sure the plate was
close to plumb. I figured as Jim H noted that the toe in and out will
very slightly as I raise and lower the tail so I figure a foot high tail
kind of split the difference. Also had the plane hanging from the
ceiling so the wheels almost touched the ground.
I'll skip all the cussing but I found you can use the original bolt
holes in the gear sockets if you drill the front sides first, than
insert a 1/4" bolt half way, next take a Sharpie and reach around behind
and mark the back side through the hole in the fuselage. Now slide the
gear leg out and center punch the Sharpie mark and drill it on the drill
press. Reinsert the leg and run the drill through it from the front to
clean it up a little. Sure would have done a lot less cussing if I had
done this on both legs instead of only the second one!
Anyway, its done and I can move on to other things that need done.
Thanks again to all for your help.
Denny, N616DR

It wasn't that bad, the airspeed never got over 70 mph and doubt it
ever got to 2 G's.
Pull out was taking my foot off the left rudder. If I had put the stick
back to neutral sooner it may not have even got to 1.5 G's

Thanks. A variation of that might just work.

For what it is worth, I found that my success in drilling that type of
holes could be improved tremendously by putting your middle finger on
the back side hole and then start drilling from the front. It is an old
Farriers trick to keep the nail line on horse shoes straight. I don't
know how it works, but it definitely does. Oh, don't forget to remove
the finger before you drill all the way though.

Hey guys,
While we are on gear legs...how far should I slide my Slingshot gear legs into
the socket? The plans don't specify a length. Any help would be appreciated. By
the way, thanks for the responses to the motor mount question I had much earlier.
Called TNK and had them a couple of days later.
