RC Schemes

Few things on the go at the moment.

Have a new flat profile P38 Lightning from Wattsuprc. I'm going to strap two 1800kv ewatts motors to it with some 5.5x4.5 props. My estimate is I should have a pitch speed in the order or 110km/hr and somewhere around 800grams of thrust. Having just looked over a fair bit of the thrust/pitch speed stuff it was an opportune time for a two engine model to come along as I now understand the advantages - you can have a higher pitch speed and slightly less thrust on each motor, because you get to combine the thrust. Easy enough eh? Only thing that is a bit of a worry is how a flatout will handle the speed. I'm actually expecting it to be quite a high drag airframe based on what I know of flatouts. All the same though, if it reaches 100km/hr and embarrasses some more Strykers I'll be more than happy.

Some superskids are coming for my GWS Mini Dragonfly to replace the stock undercarriage. Most of the Mini DF is pretty well laid out but the stock landing gear is a real weak point. Speaking of the Mini DF I've decided the honey bee I was using on clearview was way too easy to fly compared to my experience with the MDF. So, I took some advice from Paul Daniels at NQRC and have been practising using the GWS Mini Dragonfly in FMS. Setup with 0.2 m/s wind and 0.2 m/s gusts it is taking a lot of concentration and work to keep her in the air - feeling much more like the real thing so I will keep at it.

I have a busted up supercub that is in need of repair. One of the flyers at Lyneham put her in, and when the pilot indicated he was going to throw out the airframe I asked if I could have it. I don't think it is that badly damaged and plan to set her up with an ewatts 1200kv motor (I know, my entire fleet seems to run on ewatts motors) with an 8x4 prop - should get about 600 grams of thrust with pitch speed around 50km/hr. Should fly well.

I've started work on the PLD Microseether. I'm taking photos along the way so I'll do a post about the whole process at the end. For the most part straight forward build although there is a little more sanding and shaping of the wing than I might care for. However, I spose that is the way it goes with solid balsa wings.

Great conditions across the weekend. Plenty of flying in with the usual suspects. Haven't been out to Lyneham recently though. The visit out there by the Environmental Protection Agency last week has many worried about the merits of flying with so many others. To be honest, was getting a bit crazy out there with respect to frequency clashes etc.
