Redline Sidewinder


I went out to the airport today hoping to get some flying in, but with a heavy fog settled in and not going anywhere fast, I decided to just test out a battery powered tug, the Redline Sidewinder.

I've always had a hard time pushing the airplane back into the shadeport, especially after a long tiring flight. The plane weighs nearly 3,000 lbs so even though the slope into the parking spot is only 1-2 degrees, it's quite a tough bird to push.

Add in slipping feet, no great place to push against, bad angles for applying force, and a squirrelly castering nose wheel (doesn't like to go backwards) and it's a great recipe to hurt my back.

Thankfully the Redline did a great job with the task.


It's designed to have minimal weight, yet still be strong. It is powered by a heavy duty drill that drives gears and chains to apply rolling force to the nose wheel, moving the airplane at a nice slow pace.

Hooking it up to the airplane is not much harder than hooking up the basic towbar. It's obviously much heavy that the towbar, but still a manageable weight.

Each side has a pin that is retracted while you line up the U bar to the connectors on the nose wheel. It fit snuggly without scraping anything on the plane. Once the pins are lined up you release them and they spring into the nose wheel connectors. The weight of the sidewinder, plus a touch of downforce from the operator, holds the drive wheel to the nose wheel rubber.

When moving the airplane forward I found that I had to apply a fair amount of downforce to keep the chain from lightly touching the inner edge of the nosewheel. That hits on the only thing I'd change about the sidewinder, I wish there were a guard to prevent that issue. However, it was easy to avoid any rubbing by pushing down when operating the drill.

I should rarely use the sidewinder to move the airplane forward though, as we are able to crank up in the shadeport and pull right out under engine power.

What I really need the powered tug for is pushing the airplane backwards into the shadeport. And on that task the Sidewinder worked perfectly. It even greatly reduced the squirrely-ness of the nosewheel, maybe because of the extra weight compared to the normal towbar. There was no issue with the chain hitting as the torque in that direction forces the chain away from the fairing on the nose.

I had to stoop down fairly far to operate the tug as the bar doesn't come up real high (to keep the device compact), but never once had to provide any pushing power. I just needed to steer and watch out for obstacles. It's about 100 times better than the manual method I've been using so far.

Here's a short video of me removing the sidewinder from the airplane after pushing it back. It folds up quickly into a medium sized carrying bag.

Hi Jason.. Thanks for all the cool posts and sweet app... Nice post on the Redline. Funny thing, they are my next door neighbors down here in SoCal. Fly Safe!

Jason:
Thanks for the post! I had not seen it before? Regarding your comment about having to stoop over to operate it, you can adjust the angle of the extention wherever you want by simply loosening the fixing bolt on the extension tube clamp and sliding the clamp up the tube. If you have any problems, call me. Love your Fore Flight AP..

Updating data on the Garmin Perspective system

Image
After changing from the Avidyne system to the Cirrus Perspective (G1000) system, I had to relearn an important part of owning an airplane: how to update all the data the systems use. There's even more data in the Perspective, including AOPA directory data and more charts. In this walkthrough, I make use of the Jeppesen app for Apple OS X: JDM .  It has worked well for me, though I did need to call Jeppesen when I first set this up to get my subscriptions fixed up.  They gave great customer support when I did. The process starts (optionally) by hooking up a ground power unit (GPU).  In the case of the Cirrus, you can certainly do this without it, but I tend to hook it up just to be sure.  The systems draw about 8-10amps while updating, but you won't generally have the power on for long.  One tip I've read: power up the GPU before plugging it into the plane, at least for the one I bought.  That saves the plane from seeing any power spikes that might have occurred when t

G1000 transistion training - emergencies - final flight

Image
For the final flight in my G1000 transition course we focused on failure scenarios. Not the "engine goes POOF" kind but the avionics kind. Normal situation This picture shows what the 2 Garmin screens show in a normal (non failure) situation. You can see we have 2 screens - the left PFD focusing on flight performance (airspeed, heading, attitude, altitude) and the right screen (MFD) focusing on engine data, mapping, checklists, and everything else. Failed PFD screen In this scenario the screen that is right in front of you (the PFD) has failed. This basically means the screen has gone dark. We simulate that by dimming the screen down to 0% brightness. After darkening the PFD we shot a GPS approach into Rock Hill. When this failure has occured you shift the G1000 into Reversionary mode. That means the info that is normally split across 2 screens is now merged into 1. It actually duplicates the same data on both screens, but since the PFD screen is no longer functioning

A-10C Standby Compass - Sun Shade

Image
 One of the final items to add to this instrument build (besides the text covers for the lower LEDs) was the sun shade for the AR LED box.  I made this out of thin aluminum sheets , cutting it from a template using some metal sheers .    My template was created by tracing some of the actual artwork from the DCS sim, and then scaling it to the proper size. It turned out ok, not perfect but pretty good.  Primed and painted it and then installed it using 2 of the 4 holes that were already on the LED box 3D print.  I used some heat inserts in those holes to give the screws something to bite, but the holes are really too big for my inserts so had to use some glue to help out.
