GLOW VERSION:
We used both the Norvel .061 BigMig R/C and AP .061 R/C engines for all of our flight-testing. These engines happily
turned 6"x2-1/2", 6"x3", 6"x4" and 7"x3" propellers. However, because the idle on the Norvel is fairly high, we found that
using props with too much pitch made landing speeds a little high. We solved this by using a Zingali (J&Z) 6 x 2-1/2
propeller. This small diameter, low-pitch propeller worked well for us at both ends of the throttle. Our little AP .061 has a
lower idle and we therefore used a 6"x3" prop.
Finally, we urge you to always balance your propellers for optimum performance and safety. Never fly a prop that is nicked
or cracked and always make sure it is securely in place to the motor.
FLYING
If you have followed the instructions in this manual, test flying your R/C Rascal should be a pleasure! Choose a calm day
with little or no wind for initial test flights. This is important in getting the model properly trimmed. We also suggest that for
the first few familiarization flights, you or a flying buddy hand-launch the model. When hand launching, the airplane should
be launched straight and level directly into the wind, with the nose aimed at a point on the ground, about 75 in front of you.
NEVER launch the model with the nose pointed up or the wings tipped to one side. The launch should be firm enough to
achieve flying speed but not overly hard. Later when you re more familiar with the airplane and how it flies, you can
perform R.O.G. (Rise Off Ground) takeoffs.
The electric version of the R/C Rascal should climb briskly at full power and you should have no problem in getting to a
comfortable trimming altitude quickly. At altitude, throttle back to about 1/2 throttle and get familiar with the model at this
cruising speed. Take care of any trim requirements that may be needed and settle back to enjoy the flight! Now is the time
to find out how the airplane reacts to control inputs. Properly set-up, with the CG in the right location, the airplane should
be very comfortable to fly at the suggested control throws. Throttle all the way back, turning off the motor and check out
the glide. It should be quite flat and fairly slow - perfect for hunting lift! While still at altitude, with the motor off, test the stall
characteristics of the airplane. Our R/C Rascals have demonstrated very straightforward, shallow stalls with almost instant
recovery.
If you built the glow engine version, with a third channel for throttle,
you ll quickly find that the little Norvel .061 makes a lot of power! We
fly our Norvel powered Rascals at about 1/3 to 1/2 throttle, saving full
throttle for climb outs and mild aerobatics. Our Norvel engines idle so
reliably that we could also go thermal hunting with complete
confidence that the engine would stay running, as long as it had fuel.
The real secret to this reliability is taking the time to bench run and
completely break-in the engine, using the right propeller and the
correct fuel. We broke our engines in using SIG 25% nitro 1/2A fuel
(SIGCF016 in quarts). After break-in we switched to SIG 15% Nitro
Airplane fuel. Both Cox and Norvel engines run great on these fuels,
giving them solid needle valve settings and, in the case of the R/C
Norvel engines, very reliable idling characteristics.
The R/C Rascal has 3¡ of built-in down thrust. During our flight testing of this design, we found that we did not need any
additional down thrust or any right thrust at all. However, different engines may make the model react differently. If, after
flying your model, you feel that you might need more or less down thrust or some right thrust, use small washers beneath
the engine bearers or behind the motor mount to make these kinds of adjustments. The R/C Rascal is capable of
performing some reasonable aerobatics. It will do surprisingly axial rudder rolls, consecutive loops, very nice stall turns,
good looking Cuban eights, etc. In addition, we found that the airplane flies quite well inverted, once you get used to the
rudder. Our R/C Rascals have always refused to spin.
Because the model has such a great glide, landings are easy. Simply fly it right down to where you want to land it, flare a
little as it nears the ground and let the airplane settle lightly into a 3-point landing - every time! We believe you ll soon be
very comfortable with the R/C Rascal and that it will quickly become one of your favorite models. We sincerely hope that
this has been a pleasurable project for you and that you will take at least a little time to share the hobby and all of its
rewards with someone special in your life. Please fly this model safely with constant regard to other fliers, spectators and
property.
Good luck and good flying!
