Today my replacement plastic parts arrived … a new canopy and a new hull shield. It wasn’t too hard to pry the old shield off, and the new part is already to slap on.

Here is a quick snapshot showing the new orange color on the engine cowls, the upper side wing tips, and also notice the tail stripes have been repainted orange (originally red.) I’m just waiting on a replacement canopy which will hopefully arrive tomorrow and I should be able to completeley reassemble the model and … Read the rest... >>
This is 1230mm (48.4″) wing span flying wing. It is powered by a 64mm electric ducted fan. It is a simple build and flies great!
Here are a couple pictures before the maiden flight (temperature was about +18F, winds were calm, skies had a medium thin overcast.)
My one gripe about the Sonic 64
Of course we buy airplanes like the Sonic 64 because they are inexpensive, quick to assemble, and fast to get out to the field and up in the air. It doesn’t hurt that they look great and are a lot of fun to … Read the rest... >>
My story is that I missed one of the model aero sales by a day or two so I emailed the owner to see if I could sneak in my order late. He replied that he had a couple unpainted polaris arf’s and he’d be willing to give me a package deal on one of those. So I figured it couldn’t be that hard to paint a foam model and off I … Read the rest... >>
I really like the looks of this aircraft. It is a unique combination of design choices that I think should provide a nice balance of good flying qualities and lots of aerobatic capability.
It calls itself a trainer, but it is not a “learn to fly” trainer. Instead it positions itself as an entry level pattern ship. It is light weight which means it should maneuver effortlessly and not have bad habits. It has long lines so it should fly like it is on rails. It has thickened wing tips so it should have excellent slow speed characteristics … Read the rest... >>
Don’t look too closely, but take a few steps back and I think she looks pretty nice. I love the older style 185 tail and the tail dragger configuration. The relatively large wheels help me imaging this is a bush plane intended to get in an out of rough strips.
It is still winter here in MN and our ground is still covered in a foot of snow at least. I’m hoping the snow melts quickly so I can get out and maiden this airplane soon!
I was interested in the Aerosky Sky Trainer 185 because it looks a lot like a Cessna 185. It has the 185 tail and is setup as a taildragger. Technically the rear window is not correct for a 185, but there are a lot of things you could nitpick if you really wanted to go there. The other interesting aspect of this kit is that it includes a full set of float for water operations. I live near a little lake so I am hoping this will fly well off water on a nice calm summer evening.
This morning I whipped together a “precision aircraft balancer” (like the Great Planes “C.G. Machine”.) I built it out of $5.57 worth of PVC pipe and connectors from Fleet Farm and it probably took me an hour at the most.
Here is my concept drawing:
Here you are looking at $5.57 worth of PVC parts purchased locally. The one flaw in the original design is that no one locally sold those 3-way corner connectors. Maybe they don’t even exist? So I made an on the fly design change while I was shopping. The new design uses … Read the rest... >>
I sold my P-47 on craigslist today. I liked it, but for whatever reason, it wasn’t my favorite to fly and I’ve got my eye on something else … but I need to free up some space first … ! I really enjoy flying my PBY though … I need to set up a category and post a few pictures of that soon!… Read the rest... >>
I encountered two more issues that I needed to address:
The cheap retract servo stripped out.
The rear wing hold down threads stripped out.
I replaced the retract servo with a much higher quality hi-tech metal gear servo and spent about 10 minutes fiddling with end point adjustments and linkage lengths to try to get non-binding operation and minimize the servo buzz.
The stripped rear wing hold down threads was a bigger problem. I tried to glue a nut to the back to replace the cheap plastic threaded plate, but just made a mess of things, got glue on the … Read the rest... >>
The Hobby-Lobby “Hun Hunter” P-47 seems to have a small design flaw. Because of the size of the wheel well required for retracting the gear, there is not a lot of foam material along the leading edge of the wing in this area. At the thinest point, it’s pretty thin. The wing is subject to cracking in this area — starting at the leading edge and proceeding through the middle of the wheel well. There is a carbon spar in the wing so the wing isn’t in any danger (I don’t think) of coming off in flight, but it does … Read the rest... >>
