About this Plan

Pilot Twin Ace. Radio control sport twin. For 2x .19 - .25 engines. Wingspan 62 in, wing area 542 sq in.

Quote: "The Twin Ace is a twin engined sport model for .20 sized engines. Carefully designed twin makes excellent flying characteristics, and dynamic flight. The Twin Ace features snap lock construction for easy assembly and tricycle landing gear for good ground handling. Like all QB kit series, the balsa wood is mostly hand cut at the factory with the plywood parts being beautifully die-cut. Hardwood motor mount, steerable nose gear and heavy duty main landing gear are all included. The canopy is vacuum formed, and all necessary hardwood is included. A full size plan, radio installation instructions and an illustrated construction guide will all make this an easy model to build."

Update 03/09/2018: Added wing ribs (speculative), thanks to SteveBailey.

Quote: "I noticed a request for rib templates for the Twin Ace. I drew these up over the wing plan as carefully as I could. They should work fine but I cannot guarantee they will match the original exactly. I love Outerzone - I am here everyday."

Update 22/12/2021: Added parts tracing, thanks to Rainer.

Quote: "Hi, I traced all parts that are missing in the plan for the Pilot Twin Ace (oz4195), attached here as pdf. I'm currently building an original kit :) Kind regards,"

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Does anyone have rib templates for this model? Even a tip rib would help. Thanks.

Doh. My mistake, I upoaded the older of the 2 ribs files. Have now replaced the supplementary file with the correct revised version from SteveB (this one includes landing gear cutouts).

Thanks Steve. I'm sure they will be more than close enough.

* 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.
