I built myself one of MikeysRC.com FPV V3 biplanes. I put a FlipHD on it and an iPhone 4S with an Otterbox case on it; this is a very heavy set up, in case you’re wondering. It uses a Turnigy 2830 1050kv motor with a 2200mah Turnigy lipo.
I highly recommend this plane to anyone flying FPV with a GoPro or a similar heavy camera and/or equipment on board. It took 3 sheets of Dollar Tree foam board, a wood dowel, a dozen glue sticks and some strapping tape. Flies very well and I love that the COG can be moved around easily. Check it out at MikeysRC.com
So, I’ve been MIA for a few weeks or so; since early august. I have been up to stuff and one of those stuffs is a 125% Dead-Simple wing from specs found at RCGroups. Instead of 24-inch wing-span, I built mine 30 inches wide. I put on a Blue Wonder and took to the skies.
On Saturday, September 24th, I went to Ives Estates Park with my friend, Julio and my wife and son to fly the wing. I had flown it once before and had great success but crashed it. After repairing it, it looked pretty good so I decided I could go for it again.
It flew on rails. It was as smooth and straight as it gets. We clocked it at 51 MPH on the following setup:
It rolls pretty good and you can see it can fly really slow too. After a few flights, we changed batteries and flew again.
Julio had never before flown and RC plane so I thought I’d let him fly my cheap wing since he had a ton of hours on a simulator. He did f’awesome! He even dead-sticked it! Here’s Julio’s second flight:
Overall we had a pretty awesome time. The wing is crashed again but I can fix it. I might make a new one but we’ll see how much free time I have. Look out for my next project: A way-fast jet.
Also, I’ve noticed those OrangeRX 6-channel receivers have pretty good range. I flew the wing out almost out of LOS and never glitched. Pretty sweet for a $6 receiver.
I first built a 24 inch one but I felt it was too tiny for the setup I wanted. I was right.
So that’s on a shelf until I figure out what to do with it. It’ll probably end up as the wing on another project. For now I’m trying to continue on this project:
It’s partly copied from the Phase III Squall but without the long end and it’ll have two vertical stabs. That shouldn’t be done anytime soon. I expect to finish it in 6-8 weeks or so; depends on how much time I have to work on it.
As always, follow me on Twitter (@killerwin) to keep up with my day-to-day dealings.
It’s raining non-stop in Miami so I’ve taken the opportunity to build and repair. This time I’m cutting some carbon fiber rods that will be going into a 30″ Dead Simple Wing. I use a Chicago Electric Dremel-like rotary tool with a cutting blade to snap 2 CF rods down to 18″

Spent a week doing little things here-and-there to the SC and ended up with a very different model :) I’m happy because I did a lot of stuff I had been meaning to do to it for a long time.
I only have pictures (and crappy ones!) because I lost my digital camera so I had to use my mobil phone.
The first thing I did was put flaps on. I used these hinges I had bought from HobbyKing like a year ago and didn’t know what to do with them because they sucked as “hatch hinges” like they had been advertised. I like them for flaps because I can make a single cut instead of having to bevel the edge of the flaps, thus keeping the wing totally free of indentations when the flaps are up.
That was supposed to be IT. I just wanted to add flaps to the SC. I then thought “Hmm… I should put flapperons TOO!” so I did. I removed the Y-lead and installed two 200mm lead extensions on the servos to split the aileron channel in two. Then I mixed them together with two switches. So I can lower the flaps with or without the flapperons.
I also mixed in down-elevator with the flaps and also on a switch to turn it on and off. You can see that in the two pictures above.
Now, my transforming Super Cub (hopefully) can slow down to a crawl.
But WAIT! There’s more! :D
I went up to the attic and found a few goodies in a bin! I found my old SC landing gear! I put those on, as you can see from those pics up there. I had been flying with the rear end of the floats set held on by screws!
I also found a brand new rudder in a pack that used to be a SC tail feathers kit. This rudder has a tail wheel on! AWESOME for me because I had cut off my old tail wheel when I was flying the SC with tricycle landing gear.
And something I had wanted to do for a long time: I counter-balanced the elevator and rudder, as found in many clipped wing cubs. I LOVE the look of that :)
Of course I’m using the OrangeRx 6-ch receiver and taking up every single channel and every mix on the DX6i, including the gear mix, Mix 1 and Mix 2.
Actually I didn’t use the Flaps mix for reasons only known to me. lol. I can change it later if I feel I have to ;D
Step-by-step tutorials and videos on how to do all this will be coming soon. I just have to find my camera :(
The H-29 Pushprop Jet by chara is a small park jet with a mid-mounted motor and taileron configuration. It uses only two servos and three channels. The thrust pushes directly through the tail, being slightly diverted by the elevons; giving this model superb performance similar to other, more complex, thrust-vectoring models. Last time I wrote about this plane I had flown it with a 7×5 APC prop and didn’t like the performance.
So I finally tested two other propellers with the 28-26 1360kv motor. Previously I had chosen a seven-inch propeller because I thought if I went up to the recommended eight-inch it would strike the wood dowels on the twin booms but later noticed there was plenty of clearance, so I got a GWS 8×6 and an APC 8×8 today and went out to test which would give me better performance. On the bench test, the GWS 8×6 seemed to give me much more thrust but I found out otherwise at the field.
APC propellers are built for speed. Once they reach enough RPMs, they produce efficient thrust. GWS propellers, in the other hand, are built for general-purpose and scale flight. They produce max thrust almost immediately but are slightly less efficient at higher RPMs.
Watch the video and enjoy.
Wondering how I shot the video and flew at the same time? Here’s the rig:
I built Chara’s H29 Jet last week. I wanted a fast-to-build, simple, fun jet to fly at the park. I used Elmer’s Foam Board, wood dowels, and Gorilla glue. I knew it would end up heavy, but I wanted the added weight for stability in the wind. I went with an Exceed RC Alpha 370 brushless motor, 1360 kv with a 7×5 prop.
It few well but nowhere as fast as I want. I had the rates set at 100% for high and 50% low but that was way too much. I have to try 50% high and 35% low next time. I read up on people using 8×7 props with this motor so I’ll go with one of those next flight.
A few weeks ago I started to build a full-fuse foamie from Elmers’ foam board, Gorilla Glue and Plywood. It came along nicely and was looking good. I named it the T-32 Thunder. Unfortunately, on its maiden flight I crashed it because of strong winds. I believe it needed other changes for it to fly properly, anyways.
The wing survived the crash and I might rebuild the airplane someday. I still have a lot to learn.
