Slope Soaring / Re: BPLR Madslide

Hi Conor

Bill got me a set of plans for the model. The wings look ok for cutting, so what size of wing do you want. I will try to get them sorted for April at BigL.

PSS / Re: MIG 29
« on: March 31, 2018, 22:04:13 PM »
Hi Guys, well this post is getting very technical, when in practice it is not!. OK let me explain, the mig29 was designed as an twin EDF model, now AUW of the EDF model was over 2.7kg, that includes two 90mm fans, two 120amp speed controllers, two b36 1800 motors, an under carriage airup/airdown, and two 5000 5cell lipo batteries, all pushed into a small foam jet. This is how the model first flew, at speed the model flew nice!! at slower speeds, ' a big brick' and yes on landing, even on a smooth runway, a pain in the ass the land!.
So i decide to convert the MiG to a PSS model. First test flight, took out all the fans units etc, so ended up with a very light foam model, which was fired off my local hill and just did not want to fly!. Lessons leaned, model has a lot of drag and the airfoil section RG14 does not create good lift at slow speeds. Next reduce drag by covering up the air intakes, also improve lift by using a glider section wing with a larger surface area. So I cut out a new set of foam wings, and yes The section I mentioned is wrong, it is a SD3012 or 3021 I need to check, glassed the wings and fuselage, and tried another flight. This time the model flew great with a good over all speed range and lands at a walking pace. The overall weight of the model is light for a PSS model I think around 1.2kg with ballast. So, I took a model which did not fly well, made a few changes to it's design and ended up with a good PSS model which flys well off the slope!

Hi Guys, I still have the dg800, I had a look at the glider and I notice that the covering on the wings would need some TLC from my last ad post, however I will supply a roll of white vinyl which I use to cover all my gliders with the model. I will bring the glider to bigL event next week ( fri/sat/sun) for anyone who is interested in a 4m glider.

Yes guys, this is the Mig 29 I flew at bigL, a few years ago. The wing that comes with the kit is an RG14, good for ducted fan use, but not for slope flying on this model. I used the SD3020 and increased the wing by' I think' 14%. I will get a set of wings cut for you Fred when I get the CNC up and running again!

Hi John

You have an example of Ray's ( rest in peace old friend)  Fouga from dragon models range designed in the late 80's. Island models have both the Fouga and MB 339A in their range of kits, and product limited number of kits every year.

A big thankyou to Ralph for a great weekend. I did get a good few flights on Sunday morning in 38km/hr wind speed of the point with the Fouga and the micro Lunak, which is now my top fun model to fly.
