About this Plan

Sig Skybolt - Radio control scale model of the homebuilt Steen Skybolt, for .45 - .60 power. Discontinued kit from SIG.

This good scan was posted up on the HPA site by Cavaliere. I took that scan and spent maybe 2 hours cleaning it up, removed all the background noise, removed the paper creases, also darkened the ink lines slightly for better clarity, too.

See RCGroups thread here http://www.rcgroups.com/forums/showpost.php?p=27312808&postcount=21 for more info on the old SIG kit.

Update 18/03/2016: Added extra sheet showing hand-traced parts, thanks to mjb.

Supplementary files

Sheet showing hand traced parts (tailplane outline and interplane struts).

Corrections?

Did we get something wrong with this plan? That happens sometimes. Help us make a correction

I'm not seeing the horz stab. Could a second page be missing?

Good point. Looking at the fuselage side view, the horizontal stab is shown as just constant thickness balsa sheet. I guess since this was a kit plan, maybe that part was completely prefabricated and needed no further drawings (as far as assembly instructions went). But if anyone out there does have an outline of the horiz stab, that would be great.

Hi Steve; I built the kit some years ago. Great flying airplane, but unfortunately was lost due to a radio failure, much too soon in its life! I traced the stab and interplane struts on the back of my plan 'just in case'. They are solid 1/4 inch sheet. Here are scans of them but I have not stitched them together yet. The fuselage top was a plastic moulded piece, so anyone scratchbuilding will have to create a set of formers and strip planking to match the outlines shown on the plans.

Hi Steve; Here are 2 pics of my Sig Skybolt built from the kit and finished in Monokote with the kit design layout [more pics 003, 004]. It was a great looking and flying model. Maybe I should rebuild?

Looks great! Rebuild, definitely.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
