| Model review TopGun Super Cub Specifications Construction : Traditional balsa/ply Wingspan : 100" Length : 65.5" Target Weight 13-16 Ib Engine Fitted : Zenoah 38cc The Cub in all its forms is a modellers perennial favourite, this quarter scale Top Gun Super Cub is no exception.. |

| I love the cub as they offer a
relaxed alternative to the frantic funfly and looks like a real aeroplane.
There are ARTF models and ARTF models, The quality can vary a great deal.
Close examination of this cub showed it had originated from one of the
better manufacturers. The manufacturers have obviously taken the whole
process seriously, The quality of the parts matches the quality of the presentation, every thing fits beautifully and is up to it's intended purpose. |

| Assembly The assembly manual is first class and takes you through the process in simple stages, even a real novice could get this kit together without to much drama, Like me. The whole model is covered in worldtex, a heat shrink covering with a canvas texture which adds a scale finish to the model. The two piece wings use a substantial ali joiner, judging by the size of the joiner i would suggest that the wing struts are purely aesthetic and the model could be flown without them in place, but it wouldn't look right. The model comes with flaps already fitted so i used high torque servo's all-round except a standard servo on the throttle, I fitted a Zenoah 38cc petrol engine which is slightly over sized however i suppose i can fly on half throttle.

Gyro for fixed wing
As the the price and size of gyros are getting less people are starting to experiment.
Fitting a Gyro to the rudder on SAL HLG helps the the launch on models that have
limited yaw stability
Normally when you move the aileron stick you control the movement of the ailerons, if you fit a gyro between the RX output and the aileron, servo stick input will then control the roll rate. If a gust hits it the wings it will stay level, Knife edge will be held and torque effect cancelled
Is it cheating? old people will always complain," before the war we flew our helicopters without Gyros"
If we go the whole hog and have the model GPS controlled we would be missing the point of RC
I fitted a small gyro to my Micro Blade ailerons, it flew fine and very
smooth like a much bigger model. I found it hard to remember not to over correct
the ailerons in prop hang as the gyro was stopping the rotation, KE was very
easy and the one roll rolling circle was easier. On the down side it caused wing
flutter and added a little weight to an already over weight model. The aileron
response is relative to air speed and a feel for how it is flying is judged by
the response to small stick movements, this lost with a gyro in line.
One problem I see at the field is keeping the model straight on take off, a gyro
on the tail could would solve this.
The Gyro can be disabled by setting the gain to zero on the transmitter, the
gyro gain can be connected to gear, flaps or an auxiliary channel
