Tips for Success
1.
Read the instruction manual thoroughly before starting assembly.
2.
We are very pleased with the level of craftsmanship exhibited by the workers in
our factory. However, these are mass produced models. As with any ARF, take a
few minutes to go over the model and add CA to high stress areas or any joints
that appear to need more glue. Specific areas to pay attention to are servo
mounts, landing gear mounting plate, firewall to fuselage side joint, wing root rib
and motor box joints. A few minutes and a few drops of CA will help to insure
the longevity of your model.
3.
Make sure your prop and spinner are balanced! These aircraft perform as well as
they do because they are built light. Excess vibration caused by unbalanced
components can cause damage to the airframe.
4.
Buy a Watt meter! For less than the cost of a single battery pack you can
purchase one of these. This will save you a lot of time, money and frustration and
provide you with a lot of valuable information about your set up. One battery
pack saved is worth this investment!
5.
Observe the C rating of your batteries. If your battery is rated at 2100 mah and
20C continuous discharge rate then you can safely pull 42000 mah or 42 Amps
from it (2100 x 20= 42000 mah=42 Amps). Use a watt meter between your
battery and ESC to determine the number of Amps you are drawing as well as the
number of Watts you are generating. I have found it is best for battery longevity
if your maximum amp draw at wide open throttle is in between the continuous
rating and the burst rating of the battery. Prop your airplane accordingly.
6.
If you plan to run a 4S1P battery in your Yak you will need to purchase a separate
BEC. Kool Flight System’s (

) Micro-UBEC and
Dimension Engineering’s (

) Park BEC are both
excellent units for this application.
7.
We have done a lot of experimenting with various props. Using the Torque
2814T/820 on 3S we like the APC 13x6.5E and 14x7E. On 4S we like the APC
12x6E. Depending on your elevation you may or may not like these choices, but
they should be a good starting point. Remember to test each new prop with a
Watt meter attached to the system to be sure you are not overworking any of the
components.
