Thread: Cardboard construction for planes
16/10/2020 09:10:42

Yes I'd agree with Peter, if your going to stray from traditional balsa for a build I would choose Correx, it has no problem in the rain and a extended life, I still have serviceable tail planes, elevons and fins on models built 15 yrs ago.

KC, you asked if it's practical? It's cheaper and it can be done, however watch out for water or should I say rain. When I was flying something else I left Hill Billy out beside the car when I got back it was a bit soggy. Mined you, after it had dried out, I checked it over for any 'warps' etc and it was OK and flew again no problem.

Thread: new to wash out
26/06/2020 23:52:32

 

Andrew C, - Brokenenglish - is correct in my book. I control the washout in my designs the way he describes.

To help with this let my show a rib set. A 'rib set' for a Avro Vulcan, the longer rib is at the root - the middle of the wing, the smaller rib is the tip.

Notice the bottom line of the rib's to the trailing edge are flat, this helps building of the wing and following on with the trim of the model in the sky over a wide range of flying speeds. The washout effect comes from the main bulk of the wing in the middle flying down it's chord line and this makes the tips show washout, the incidence of the tip chord being different to the middle root chord/s. Controlled via my curves, measurements and built flat on the board.

9 wing ribs  - 10 rib shapes seen

Below:-

The Root and Tip ribs shown with each other. The main incidence setting coming from the larger rib having the curve come up from the bottom line at the front to the leading edge, and all ribs / wing built from a flat building board.

Rib fronts showing different incidents

This method I believe makes the model have great stability and control, even left to fly 'hands free' sometimes. See the foam wing in action, using the same wing sections shown above. A nice stable wing, with the model pilot able to place the model where he wants.

Wood nose intake

In lock-down and on 80% furlough I've been categorise by ('hwmbo' ....is that how it's spelt? ....as a DIY Lifer.

After numerous jobs and various total room make-overs around the house, I've asked for day-release x 10, the reason for the request is to get my Sabre Jet finished.

Judgement has been made in my favour, so Thursday, tomorrow is the day I get back to the modelling table/ bench.

Hallelujah.

Covid 19 has a lot to answer for.

I shouldn't compliant, over the period I've have had the odd bike ride out, sometimes accompanied with - hwmbo - .

I've even wander ( on our bikes ) by the Buckminster site, however no flying. Has anybody any idea when it will be open?

As of this date considering all the conversions of the Lidl glider, this one of Stephen Jones is the most sophisticated, yet.

A successful flight.
