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.

Conclusion  

From the build point of view it is hard to fault this model, Everything fits as it should, the hardware is fit for it's use and instructions first class.
She is now sitting ready to go, Thanks for Steve whitehead for his advice and fitting the engine for me. If she flies half as well as she looks i won't be disappointed ...

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

Slope flying
Sunday 1st

There are still a few of us out on the slopes, the conditions on Sunday at the west slope of Selsley common were spot on. Where was everyone, at Frocester perhaps? These pictures were taken from my 12ft OD thermal soarer, it hardly notices the camera at all and is a big improvement on trying to take aerial pictures from a Mirij.

Thursday p.m. 12 mph at Selsley not smooth but some good thermals

Friday
A light breeze at Haresfield, Guy's Slipstream out performed my elderly Zagi

A strong wind at Frocester

Sunday at Frocester
another strong Breeze, Peter's Adrenaline seemed to like the conditions .
Guy's Slipstream was blown behind the slope and landed in a tree, there was also a Delta model in a tree on the front of the slope
