I received the "R" version plans in the mail back
in October '05. I'm glad Curtiss Pitts drew these up for Steen
Aero Lab. The few guys who have hung radial engines on the
front of their Skybolts have had to work through some technical
issues that I really didn't feel like dealing with.
Update: December 16, 2006. Just
heard in the biplane forum about updated CAD drawings for the 3-piece wing. Called Steen Aero
and spoke to David Stone and yes there are updated drawings. Explained to David that I purchased
the R plans supplement for $65.00. The new, updated supplement is 100 dollars so he said for the
difference, 35 dollars, he'd send out the updated drawings to me. Went online and ordered... got the
new updated drawings AND a 2006/2007 calander with the cut-away drawing of the 'bolt as the pictures on
it. Sweet !
Looks like I'll be attempting that 3-piece wing now. Thirty pounds heavier but much stronger.
If it weren't for Curtiss, I'd be building a conventional
Skybolt. A beautiful bird, just not the one I wanted to build.
"R" version has a totally new fuselage. Not a modified
Skybolt design. Along with the "R"adial engined
fuselage I got blueprints for the 3-piece wing. Not sure if
I want to go there with this. There are several areas on the
blueprint that need to be worked through. Decision still up
in the air on that one.
The new design was based on using the Vendenyev M14P nine-cylinder
radial engine, both the 360 and 400 horse powered units.
Some stats on the plane.
Empty weight is 1500 lbs with a gross weight of 2250 (aerobatic
weight of 2000.)
Length 19 ft
Height: 7 ft
G-load for this Gorilla +6/-4.5 (typical Pitt's G-loads)
Ultimate load is +9/-6
Upper Wing Airfoil is a NACA 63zA015 with a sweep of 6.5
Lower Wing Airfoil is a NACA 0012
Seating for two (with a nice prone position for higher g
Fuel capacity is 35 gallons with an additional 18 gallons
optional. (for those long cross-contires) :: Update:: Only a 29 gallon main tank.
It's going to be awhile before I'll load something up to
this page. I have plans on welding up the fuselage this winter/summer.
I have my tubing list already made up for what I need to order
from Dillsburg Aeroplane Works. Cheapest, and best 4130 tubing
Dillsburg Aeroplane Works

I'll let you know how it turns out.
August 4, 2007 custom made tables for a biplane fuselage...
Drove over to Gus' today. Picked up a boat-load of airplane stuff (actually a pick-up truck load.) And with that heist I received two custom made
tables for fuselage building. It's been good to Gus for four biplanes, I'm sure it'll treat me just as nice.
I'll be painting over the old drawings with white primer and starting to draw the lines for the R version of the Skybolt in a few days.
Never thought that I'd be doing this... cutting tube and welding up a fuselage. Can't wait to get started !
August 14, 2007 The word is...
Looks like I've already written down the word. Did it
on the 4th of August. Duh.... looks like I'd better get started then !
