A rare decent day on the slope allowed for the completion of this video after many, many wet and windy months... https://youtu.be/KlAjpL-4EgY?si=rSiTrdZjlPnUU4q_

Good luck, Franz...

As featured in the current Scale Gliding column...

The weather finally relented enough to make this video of a much-modelled motorglider

Interesting stuff... Look forward to a flying report

Nice work, Bob...👍

Good job, Peter, trouble is...you now have an empty workbench!

The sleek F4 takes to the skies...

More fun with the tiddlers...

As good if not better than spoilers alone, but of course not as good as spoilers and ailerons together...

Plan coming to RCM&E soon...

As the AMT section is NACA 009, which is symmetrical, both AMT halves are identical, allowing for variations in any hand-built structure. I don't seem to have many pics of the process for the Petrel, but here's one from the 1/4 scale Rhonadler, which is identical. As you can see, once the root and tip ribs are in place, followed by the TE, you can eye up the TE to see that it is parallel, before fitting the remaining ribs off the board...

One of the most useful of tools in my bijou workshop is the long, flat sanding block. A sheet of 5 or 6mm balsa with 40 grit on one side and 80 grit on t'other. This is ideal for the task of sanding down the aileron spar on a wing and rendering it flush with the ribs. You needn't worry too much about slightly re-profiling the wing ribs: if they've been cut by hand (as mine always are) this will smooth out the inevitable slight differences...

As Engineering & I have zero in common, I outsource this job to my pal Smallpiece... He tells me he gets Silver Steel rod in the required diameter from E-bay...

In support of this month's free plan, the Minimoa in action...

A few weeks ago I found myself alone on a slope with just the little Wolf for company. (Pure laziness: the model will sit in a small car, fully rigged and ready to fly) This glider is a lively machine to operate, and I wondered at last, what it would be like in Sedate Mode. (I won't use rates, as I once lost a model rolling it with the rates out & I'm still in therapy). It turned out that those super-large ailerons were mostly the culprit, so I've included the new throws for those that like their excitement in smaller chunks. SEDATE MODE Ailerons: 25mm up, 12mm down Elevator: 20mm up, 14mm down 75% elevator comp Elevator: 20mm up, 15mm down Also, the flying surfaces were re-covered in the new HK matt clear film, with solid colour film as trim.

These are a couple of versions of the RCM&E 5th scale Petrel plan, scaled up to 1/4...

Chris Williams here...thought I might drop in a share the odd bit of scale gliding info now & again...
