About this Plan

Sopwith Triplane - Radio control scale model WWI Triplane fighter, for electric power using geared Speed 400 motor and 7 cells.

Quote: "Here's a 36" span (1/9th scale) park flyer drawn, built and flown in 2001 and published in FSM as a free plan in the May/June issue. It's a simple one-piece build, with only the final assembly requiring particular care to get all the incidences right. Originally it used a geared speed 400 and 7 NiCad cells but a suitable brushless and LiPoly set-up would be very easy to arrange. It flew very well indeed and looks the part with scale colours, a pilot and a machine gun. The articles are scans from the original magazine, long out of print. The plan acknowledges the inspiration of Peter Rake's Sopwith Pup (oz9660) plan from a year or so earlier - thanks Pete!"

Note: This plan is one of a series posted on RCGroups by the designer, Mike Roach (SopwithMike) himself. See I checked with Mike and asked if he was happy for us to host copies of these plans, here on Outerzone: He said: "Hi Steve, I would be very happy for any of the plans I put up on the free thread to be put on the Outerzone site. I'm a great admirer of the site, have visited it often for inspiration and it's one of the reasons I have offered my own plans free to copy. I'm hoping Steve85 will be offering short kits at some stage. If anyone has comments on any of the plans, I'd be very happy to amend drawing for future builders. All the plans are hand drawn, so there will be the odd error and ommision! Best wishes, Mike"

Note: This scan of the plan is a 200 dpi bitmap, and was quite noisy, so I spent some time cleaning it up, removed the paper fold marks. See supplement raw scan in case any crucial areas got overly cleaned.

* 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.


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.
