Profile A-26 Invader - Control line profile scale model twin.
Quote: "Are you interested in a realistic twin engine control-line plane which will require a minimum of construction time and cost and will give excellent performance? The A-26 Profile Invader may be just what you have been looking for.
I have always appreciated the clean lines of the A-26 but since I specialize in stunt flying, I didn't feel that I wanted to take the tines to build a regular scale model of the plane. The profile was the answer. Expense and construction time are kept to a minimum, and performance is better than the usual scale model due to lightness.
Two Enya .19 engines, with a top speed of 85 mph, were used in the original plane and found adequate. If weight is held to a minimum, there is no reason why this model cannot be successfully flown on two good .09's. The plane flies well on either of the two engines as can be seen in the photograph showing only the outboard engine in operation. Landings are fast, however unlike the usual scale model, the plane glides well and is completely responsive to the controls during landings. The addition of a simple throttle control unit will increase the versatility and realism of the model.
Let's begin with the wing. Both right and left wing panels are identical except for the control system parts on the inboard (left) wing: I did not weight the outboard wing tip; however, you may want to add approximately one ounce of lead to insure tight lines..."

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

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.
