FTFB F3A Pattern Aircraft

[vhandon]

I was interested in a plane capable of pattern flying but did not find any plans so I designed(copied) one.

I did not add dihedral but it might need a little. The plane is capable but a little bit of a handful. With some fine tuning and coupling programming in the right places, along with a gyro, I bet it would make a really nice and cheap pattern trainer.

Wingspan: 41"
Length: 42"
Weight w/o battery: 530g
Power Pack: C
Battery size tested: 2200mAh 3S (4S capable)

Nice work and great flying - it really flys well. And thanks for the plans! Take a look here for some other ideas.

Rapier, the latest edition to my fleet of vintage Pattern aircraft

I just finished building the Rapier. The design is by Dan Santich from 1970. My build is 70% scale of the original. Building methods are FT using Adams Readi Board. This is my largest and most ambitious build to date. Wing span is 42", length (including spinner) is 36", wing taper is 1.5/1...

Nice work, good flyer; and you're a good pilot. What is all up weight and what battery are you using? Please add some pictures of your construction process.

Weight came in at 530g without battery. I used a 2200mAh 3S battery but a 4S would be even better.

Impressed, even looks like a pattern plane of the olden days.

You might want to put some landing gear on to help with takeoffs and landings.

Suggest your explore props to fine tune the pattern plane. Look at the possible diameters and pitch. You will be pleasantly surprised when you hit it. A good brand of prop is APC's and also look into their wide blades which has excellent bite upwards as well as acting as a break on the downward movements.
