About this Plan

Pacific Ace. Radio control sport model. This is a 250% enlarged version of the classic 30in span rubber model.

Quote: "It had to be large enough to see way up there when you shut down the engine and it turned into a soaring machine, but not so large that common stock could not be used in construction. Since the 30" Pacific Ace had the best detail, it was decided that R/C version would be a multiple of the 30" one. Two times would be too small and three times would be too large to fit common building stock so we split the difference and decided upon 2-1/2 times. That would make the wingspan 75", if we used a 6" center section, each outer section would be no longer than standard 36" length balsa and spruce. We normally cut our own hardwood from white pine which is easier to work and much less expensive, but if we expected someone else to build the plane, it would be to their advantage if they could use readily available materials. What about the fuselage - it is 43" long? Note, all of the fuselage forward of the TE of the wing is spruce except for a couple of cowl pieces. Aft of the wing, the fuselage is all balsa with the two longerons on the bottom of the fuselage being spliced where spruce transitions to balsa - voila, standard stock. Get yourself a bunch of 1/4" square spruce and balsa. The balsa should be medium hard as you do not have to worry about making the tail light. We had to add weight to the tail to get the plane to balance at 1/3 of the wing chord. This is an excellent beginner's airplane. It is extremely easy to fly and if you get into trouble, all you do is take your thumbs off the sticks and the plane squares itself away (more about that later). It really isn't all that difficult to build and we will give you all the help we can. If you have built a few kits such as the Eaglet or the Eagle, you are ready for this scratch-built plane."

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

The distance shown on the frontal firewall drawing, is too short the size between the bottom longeron and the next one up is 1/4 inch or 6.4mm too short. Thus the whole firewall is too short by 1/4 of an inch. Regards

Yes, I think you're right. Seems too short.

* 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.
