ARF – Almost Ready to Fly – is a worn-out acronym. Most R/C aircraft models on the market today are ARF models. When considering a model, the big and fuzzy questions are: How MUCH of an ARF are we talking about? Has it been thoroughly tested? Has it test flown? Is the hardware pack useable? Does it at all fit the model?
This is one of the major areas where Hyperion stands out in a crowd.
Each and every model undergoes the critical scrutiny of Hyperion staff on several continents. You can be assured that thorough in-flight test has been been conducted. Building methods and techniques are constantly improved and choice of materials considered always.
All Hyperion aircrafts are available with an optional brushless motor set. These sets are complete down to the last bolt and nut you will need to mount you new motor. Building time could not be shorter, as we have prepared all components to go together with ease and without any technical issues to solve. Practitally, it means that it takes under 5 minutes to install your Hyperion driveline because everything is pre-made and just fits.
Symphony or Chaos ?
When you get yourself the original Hyperion motor set, it is not just a short build time you are winning. The motor set has been carefully chosen among multiple alternatives that has been weigted up against all aspects – choice of lipo pack, flight time, speed vs. thrust considered for each model and not least; how does it all perform in real life.
Let’s Assemble a Yak55 25e Black
We will use the excellent Yak55 25e-class model for our photo-shoot. Let’s begin!
Start by installing the control horns in all surfaces. All you need to do is cut through the covering to reveal a precut slot for the included phenolic horn
With just little epoxy you can secure the horn – and best of all, the wing looks great from above!
Install and lign up the horizontal stabilizer. The covering on both stabs are removed from the factory as this process is difficult to do properly – if you use an X-Acto blade you might cut too deep and thereby damage the stabs.
IF you use CA to glue in the stabs make sure it is of the best quality. ZAP CA is among the best we have found and the joints are very strong. Alternatively, use a 30-min epoxy so you have time to work
Fixate the CA hinges. Do this in one session per hinge – it is very important that you do not fall for the temptation of first gluing them into the wing, and the surface. As the hinges are covered in a cloth that helps transport the CA into the slot it is not desireable to have this cloth filled with CA prior to it seated properly in the surface.
The undercarriage takes 2 minutes to install. As simple as it looks. It is good to install it at this point as you start installing the motor.
Prepare your motor. If it can be mounted both front- and backmounted then make sure to use the collar included in you backmount set. Purpose is to secure the bell over the shaft. This Z3019-14 motor will be backmounted so we will use the shaft collar.
Install the prop adapter.
Install the backmount – be careful not to destroy the screws.
Move on to fixate the motor against the firewall. Use smaller hand tools to gain access to the inside of the motor box.
What remains at this point is the radio installation – it is a very straight forward step and all fittings and rods are included in every set.
Have fun assembling your next Hyperion ARF!
