For the past many years I have mainly been doing 3D helicopters, so my building experience has been buying and bolting. I have started doing some sloping and started with a Mini Mach. I also have an Ahi, but now that I have plans to go to the Sunset event I want to make sure I have something to fly (Goat Rock where I have been flying is a bit sketchy when landing). So, I just bought the Alpha 2M from Aloft. So, not being that much of a builder, and having a glider with no instructions... Read more ..read more

Hi Guys, as many of you know I have spent quite a lot of time and more moment recently trying to re-invent and improve all of my old models after the theft of the original moulds by S.F. Zhou in China. So far we have: Schwing Corsa II 108" (New moulds almost finished) Stormbird Forza 100" (Test flying very soon) Firebird 60" (Test flying very soon) Gremlin II 60" (New moulds almost finished) Apart from some great aerodynamic improvements, plus some practical assembly changes that have been...

Finally got my hands on this beauty! I thought I would do a build log in a separate thread then Doc’s since his is more focused on design aspects. I’ll be using GDW servos and Tomas Liu frames for this one. First impressions are holy cow this thing is big! Ive flown larger scale birds, but for a pure slope machine this has a serious presence. I love the somewhat scale reminiscent bulbous fuselage, plenty of room for even the largest batteries. Another nice feature is that if you wish to go... Read more ..read more

PRANDTL lift distribution as it relates to flying wings.
Aloft Forums » Gliders
by Red
3w ago
Hey All, Wayne asked for some info on the PRANDTL wings and suggested I start a new thread, so here it is. Ludwig Prandtl was a German fluid dynamicist who was the first to create a tool (equation) to predict the performance of a wing in 1919. Dubbed Lifting Line Theory, he correctly predicted down wash and wing tip vortices (he called them Vortex ribbons) among other things. Lifting Line Theory states in part that the most efficient way for a wing to produce lift is with an elliptical... Read more ..read more

Ballast tubes! How to make a fast, easy and good setup.
Aloft Forums » Gliders
by Doc James Hammond
1M ago
Hi Guys, Over the (Many) years I have seen more ways to keep ballast in ballast tubes than I can shake a stick at. Mostly they involve Nuts screws washers and bolts - and other laundry related systems. All have been ingenious - some more than others I have to say. Me? I use the good old Kelly Johnson KISS principles for most of my stuff. To whit - and Guys this is really fast and easy! First, measure the ballast tube for the slugs you want to use, in this case 8 of them... Read more ..read more
