March 2012 Update

Sadly, the MAYDAY blog has been very quiet lately. I’ve been flying and building but I just don’t have the time to keep updating the blog as much as I used to. I will make time soon, you can expect some videos in early April.

In the last couple of months and coming up:

  • Built a Parkzone Stryker F27C from parts with a Turnigy motor. Have to clock it but I guess about 70 MPH.
  • Fixed damaged Super Cub.
  • Started taking a lot more pictures and videos of everything (just haven’t had time to upload).
  • Planning to build a new plane or airboat from scratch.

As always, I’m available for flying around South Florida and for RC help via email or social networking. My number one goal with this site is to help RC pilots with issues I had and wished someone would help me with when I started flying three years ago.

You can email me, hit me up on Twitter @killerwin, PM me on RCGroups.com, comment to this or any blog post or hit “Call Me” down there to connect to my cellphone.

Stuff You Should Love: Prop Savers

If you’re flying like me, you’re probably replacing propellers and bending motor shafts like there’s no tomorrow. This is especially true if you’re flying from a grass field. The problem is that when your propeller hits the ground, either it takes the force of the impact or, if it’s still turning with throttle, it can bend the motor shaft.

Early on when I started flying RC I kept hearing about prop savers. I didn’t really get the benefit until I used one myself. Now I use a prop saver on every 3 or 4 mm motor shaft! I’d love to say I have no more broken props or bent shafts but all I can say is that it has drastically reduced prop fatalities and shaft replacements.

Here’s how a prop saver works

It’s a small aluminum ring that fits on the motor shaft like on Figure 1. It has two milled, threaded holes where little screws go and it comes with one or two rubber bands (you only need one).

Figure 1: Prop saver installed on a motor. Notice the rubber band holding the propeller on.

After putting the prop saver on the shaft you tighten the screws so that it doesn’t spin free from the shaft or slide off the shaft. You then put the propeller onto the front of the prop saver and attach the rubber band from one screw, around the front of the propeller and onto the other screw.

Now your prop has some room to flex back-and-forth and spin free from the motor a little. So if you hit the ground, the rubber band takes the force a little instead of passing it to the prop or shaft.

Prop shafts are cheap! You can find one at a local hobby shop for about 3 or 4 bucks but you can buy a pack of ten (3mm) online for less than three dollars! (or 4mm for less than four)

 

They come in all shapes and sizes but all do the same function: save props… and shafts.

 

Park Jet Sneak Peek

The foamie jet is coming along nicely. I’ve finished gluing the wing and fuselage. The vertical stabilizer is on and all that’s left is to cut the elevons before the electronics and parts arrive. I must say: it looks sexy! I can’t wait to see it in the air.

A bit of sad news: HobbyKing.com has announced a new “V2″ radio system to replace my radio so I think that system is canned. The receivers are out of stock and don’t seem to be coming back in. I think it’s time to invest in some kind of modular radio.

Flaperons Using T6A Radio

Recently, I was discussing the T6a radio at the Super Cub Club when the topic on flaperons came up. I decided to give it a try with my SC.

I started out with a servo on CH1 for the left aileron and a servo on CH6 for the right aileron. I programmed the first mix (MIX1) for standard ailerons as follows:

  • Mix Num: MIX 1
  • Source: CH1
  • Des: CH6
  • Up Rate: 100%
  • Down Rate: 100%
  • Switch: ON

If all you want is ailerons, this is where you can stop. Next, for flapperons, I used up the remaining mixes (MIX2 & MIX3). MIX2 for CH1 (Left Aileron) and MIX3 for CH6 (Right Aileron):

  • Mix Num: MIX 2
  • Source: VR B
  • Des: CH1
  • Up Rate: 75%
  • Down Rate: 75%
  • Switch: SW B
  • Mix Num: MIX 3
  • Source: VR B
  • Des: CH6
  • Up Rate: -75%
  • Down Rate: -75%%
  • Switch: SW B

This results in the ability to switch flaperons ON and OFF with Switch B (SW B) and adjust the angle of the flaperons by rotating Pot B (VR B).

There are many options and settings to play with here, including aileron differential; to read further, see the RCGroups.com post where I found the info I needed.

Flying over Live Oak, Florida [VIDEO]

In early September I took a trip to see my family in Northern Florida and I couldn’t waste the opportunity to fly in the countryside. I packed up the Super Cub and took her along for the ride. While up there, I had many smooth flights, including some of extended length due to a few thermals and well-placed winds. Here’s a video on-board the Cub on a very windy flight.
