You may recognize this beauty from our most recent Let's Fly! Episode. Today we Build, Tune, and Fly the FX79.
The manual was very well done with all the specs right on the front cover.
The CG measurements were very clearly labeled which was beyond nice.
In the ARF version we built the carbon fiber spar and the servos we pre-installed.
If you do need to manually center up your servos for any reason, don't be afraid to pierce the foam to get to it. It can take it.
One really cool tip in the instructions is to add a small piece of fuel tubing (not included) to keep the clamps on the push rods from opening.
There is plenty of space in the fuselage for all your toys.
The mounting plate was also an impressive size, pre-slotted for velcro straps.
We would recommend gluing the fins on before you try to mount the wings. It makes the process a little easier.
The wings attach through the carbon fiber rods that slip inside each other. There is a small tension clap and one screw on the wooden plate which was also pre-installed.
There are several methods for mounting your FPV gear, the one above is with the plate included with the kit. The only problem was the recommended markings for the plate were pretty far back and the majority of the bottom frame will be the planes nose. We moved it forward a bit to compensate.
If you want to avoid this problem all together, you can cut out the foam and give your plane a pretty little face.
Before you glue down your battery plate, tape it down and check the CG. Depending on the weight of your battery, it might be sitting too far forward on the plate if you just glue it without balancing first. Remember, tape is easy to adjust, glue is not. Once you're satisfied, lock it down with whatever type of glue you like to use.
Josh's Recommended Dual Rates / Expo
- 100% / 30% <- Best for fast turns and maneuvers
- 70% / 30% <- Best for general flying
- 55% / 30% <- Best for slow gentle flying (be wary of wind though!)
