cloud snooper build log

Hi and welcome to my build log of Ed Konefes 1939 Cloud Snooper @ 48"
Typing is not my thing really so this will be mainly photo's. This is going to my first electric conversion vintage plane, fitted with a 2822/17 1100kv 102w motor and 1300 3s lipo.

Just a quick up date.
Did not get anything done to the model yesterday, as i spent most of the day talking plane's with fellow modeller's , and i am banned from the workshop on sat night's [wife's order's]. No chance of flying today, far to windy, so got in a few hour's on the cloud snooper today

Some great looking carpentry in that fuselage, this is going to be a nice model.

Thanks sundancer, that's quite a compliment coming from a modeler of your reputation.

Ummm. Don't think you will need too much movement on those elevators! Bring on the exponential

elevators

I think you may be right sundancer,but i always think that it is better to have a large elevator moving a little, than a small elevator moving a lot, but i may be wrong.

Yes, you are probably right about that. In any case, when converting vintage models to radio, many people fly them with the CG further forward than on the original which results in quite "heavy" elevator response.

Not directly relevant but it is interesting to remember that with free flight models we used to deal with longitudinal trim changes via packing pieces under the LE or TE of the tail plane, and even wafer thin packing could have a very dramatic effect. Yet a friend of mine built a "Bicki" vintage powered glider and wishing to preserve authentic appearance fitted an all moving tailplane which he pivotted at the leading edge, reasoning that only small movements, equivalent to the above mentioned trim packing, would be needed. To our surprise we discovered that, in order to produce any significant deviation in the flight path, relatively huge movements of the trailing edge up and down - as much 1 inch either way - were needed. This is certainly not the case with a normal AMT such as I used to use on my thermal soarers, pivotted with 20 - 25% of the area in front of the pivot point, only small angular deflections are needed for complete elevator control. I returned to an AMT set up like this on the recently completed Mamba and the pitch response is excellent. No doubt there are sound aerodynamic reasons for all of this, but as long as it works, why worry.

That really looks nice! The best I can hope for is that mine looks half that good when the time comes (and it's uncomfortably close). Anything unexpected in the process to watch out for?

Looks great and it is an unusual model. Nice to see something different. Looks like HobbyKing provided the electronics. Its hard to beat thier 10g servos at around $3.00 US. I'll be interested to see how the tissue goes over the film. I've only done it once with Jap and it came up a little blotchy but great otherwise.
Nice build, well done.
