Nasa's Al Bowers and his work on the Prandtl

-D- Wing, Where big science and aeromodelling meet.

The D wing with proverse jaw controls on the wing tips !

Al is resurrecting Lidwig Prandtl 1920 then his 1933 paper on stuff like 'ribbon vortex', ' minimum induced drag for a given span' and ' elliptical span load'.

Also to add interest in this, did you know before the Spitfire left the drawing board R J Mitchell and the Supermarine designer Joseph Smith had a evening dinner with Prof Lidwig Prandtl at his house, what info was shared I save for any article that may be written.

I think a article on these things I've mentioned would be very interesting. For a taster watch these video's.

Morning Onetenor, the main material I may use will be a depron white foam, supported on the inside by 1.5mm ply in the fuselage and a couple of carbon rods in the wing.

Thread: Can Doo it

Can Do C of G

Hi Wayne, I believe its 50 mm / 2" in front of the LE of the main wing where it come out of the fuselage , also it needs a up reflex setting on the main wing ailerons of about 0.12" / 3mm and the front elevators need to be set at 4mm down elevator - ( which is like up trim on this model ) .

Here's a link to some features and some flying pictures.

It was featured in the magazine in December 2013.

Thread: epp eagle clone
15/11/2018 09:11:17

This one is not a clone its from DW Hobby - the mini eagle powered glider.

Keep watching the video from time 7:35 onwards because you'll see and hear wonderful set of shots and piece of music and video put together from the 'RC Model Geeks' of Hayling Island UK.

 

Very enjoyable and relaxing to watch.

Thread: Pop bottle canopies and cowls
03/11/2018 11:05:31

 

I've made a mould for a Hurricane canopy.

First I made the outside canopy box with 3mm balsa using the fuselage as reference, then filled it with plaster. Once dry I sanded it to shape, the canopy frame work is with 1.5mm ply from paper patterns layed over the mould. Can you see the adjustment I had to make on the front of the mould to improve the canopy and fit to fuselage? This was filled with plaster and sanded back. I glued a base of ply on the bottom of the mould to firm and support the mould edges.

Show us your Scale glider, - all I can do is show everyone is a video of a similar gift coming to myself prior to Christmas this year, as some would say "a early Christmas present", in fact I think a lot of subscribers and magazine purchasers will get the plan before the end of the year, that's all I'm saying.

It's a : Goppingen GOl 1/7th scale 2000mm span 38 oz AUW using HG35 / 12 wing section with no washout.

Hi Dave, Tornado cockpit mould, I've done one at 100% size - model size that is -, if you have a go there easy to make, I made it from 15mm MDF board stuck together, frame work from thick card

By chance a local school, a couple of hundred yards away from the house, has one hiding behind a shed, its full size though !!!

A brilliant conversion, well executed, by Erwin.
 
 
 
 
 

 

Some great views while Erwin is flying his Lidl glider, then to round off a great day out a walk and cycle ride back home.

In A past life working in insurance, that involved a plan that gave coverage of one off 'fete insurance' that included aerial displays if needed, I'd love the see the schedule and premium coverage it seems high at 10 pounds for a person, when it costs few pence per hour per person.

A lot of BMFA member glider flyers have Country Cover. **LINK**

I wish things could be kept simple with real cost benefits to access to land and its use.
