Default Aircraft tail trap

Where can I find the field device that is stuck into the ground and serves as a hold back for your aircraft at the field? Found one online but at $55 was a little steep. Also some I have seen seem to be too short for trike gear aircraft.

Not trying to be a smart allec, but I use a piece of rope and a 50ΒΆ tent stake to hold my planes. It works on everything from my 20 size planes all the way up to 46% Ultimate.

I took the neck strap from my TX that I don't use and hooked it to one of thoose dog chain spikes.

Like RCKen, I have been using a rope and a 12-in. spike (nail). Unfortunately our 50-Cent spike now costs about $1.00. Still inexpensive.

For several years now I've been using two 3/8 inch diameter aluminum rods (cut from a longer rod purchased at hardware store). One end of both rods is ground down to a "soft" point, making entry into hard ground easier.

The opposite end of both rods (the tops) are bent to 90 degree angles. These pieces are about 3" long and go over the Horizontal Stab preventing the tail from rising up and maybe going forward, plus they provide good "pull-out" handles to get them out of the ground when the day is over. I usually carry a hammer to drive them into hard ground. If the ground is soft just lean on 'em and they go right on down.

All my planes are tail draggers. The rod's heights for trikes will be longer, depending on how high the stab LE is off the ground. Measure the trike tail height at rest and cut accordingly.

These aluminum stakes are strong, durable and have held everything I've flown including 8 and 9 footers. Once your engine is running and you're ready to taxi, just grab the vertical fin, lift the tail up and over and go.

Using these rods elininates someone holding my plane's tails during start-up. Please paint them orange for visibility purposes. Don't want anyone tripping over them while you'e flying! May help you from leaving them sticking in the ground when you're loading up to head home. Good flying!

I tried one of those when a club I used to fly at forced everyone to use them. I felt it was a pain to deal with. Just hold the nose and be careful.

Ignore Tommygun - he won't be with us long!

SECURE THAT AIRPLANE BEFORE STARTING IT!!!

It is to easy for something to happen and not be able to react to it while holding a plane.
A friend inadvertently bumped his throttle and when the engine started it was at high RPM.
He had trouble holding on to the plane with one hand so he could reset the throttle.

There are many good and inexpensive devices available.
The suggestions above are good.
I saw an article in a magazine that suggested a holder used to hang up a bicycle. Nail it to the ground.
I've seen them at Lowes and they should work fine.
Others have used a bean bag full of lead shot with a rope to tie around the tail.
Tie the rope under the horiz stab and over the fuse in a bow so it comes untied with one pull.
I don't know how much they weigh, you'll have to experiment some.

I just built a couple of starting stands for our field. The plans are available here at RCU.
I don't remember where, but try a search.

Good Luck,

I have one of these from Midwest:http://www.midwestproducts.com/item_...asp?item_id=56.
I use it for my 33% airplanes, no problem. I also have a friend that builds an aluminum version that lets the vertical posts drop after you move the tail backwards away from the tail trap. Don's Hobby also sells a trap for around $100.

I drilled 3 holes in a scrap of 2x4. Put a section of dowel rod into the two outside holes with 30 minute epoxy. Put a spike through the other hole pointing the other way. Put some pipe insulation over the two dowel rod pieces.

The section of 2x4 cost nothing.
The dowel rod was 3/4" and cost a couple of dollars.
The spike was 72 cents.
The pipe insulation is 90-some cents for one LONG piece.
The epoxy I glued the spike and dowels into the 2x4 was from my airplane supplies.

The picture shows it in use this morning holding the Tiger2.
BTW, today was it's "maiden hold back". I built it last night in about 10 minutes. It cost about $4.

Here it is in use. Drive into the ground with your foot, Fold legs up, put plane in, start plane, fold legs down, taxi off.

Here is what I came up with..Just some PVC pipe and a large bolt..I put some foam pipe insulaion for the uprights..I use 2 long screwdrivers on each side of the rectangle to hold it down..Just lift up the uprights and the stab holds them up..pull the plane back about 2 feet and the uprights just fall down to the ground..

I must be a cheapskate.... I have my flying buddy hold my plane.[8D] Works for the small and the big stuff. The flying buddy is also my safety-pilot. I am his helper, of course.

Safe Flying!

Same here. I use a 50ΒΆ tent stake and 25ΒΆ worth of nylon rope. It's held back everything up to a 40% size plane.

Just drive a couple of big steel stakes used for concrete forms into the ground. Put some padding on them and stick the nose between them. But wide enough to pull the plane out without hitting the prop while its running

Same here but instead of a 50ΒΆ stake I use a $2 stake with a handle A large screwdriver that is

In 26 years of hand propping RC models (I hate using electric starters), I had never considered using any type of tail restraint (unless I was breaking in an enigne and needed to run it for a while) until a guy at the field gave me a rash of stuff for not using one. It was a bit of a PIA at first, but is not too bad and it is nice to run up the engine without getting slime on my shoes (I always used to stand in front of the horizontal stab and hold the plane with my ankles).

It isn't a rule at our field, but I do use one now. I use a huge screwdriver and some 1/4" nylon rope in a loop. I have a small loop on one end that is fastened to the shaft of the screwdriver then pushed in the ground. I then loop the rope around the tail, slipping the loop over the top over the screwdriver. Once the engine is running, I lift the loop off the driver, pull the rope from around the tail and the plane is loose. The biggest pain is remembering to take the thing home!

I don't know, I've been doing it that way for nearly 20 years, so I guess your definition of "long" is different than mine. If you are unable to hold on to a model airplane, I'd be concerned something else would get you, like a gust of wind. I guess for extended running such as for engine break in they aren't bad. I adjust the needle with the nose pointing up so it won't lean out in a climb. A tail holder will be of little use in this situation.

I find it ironic that a lot of the guys that are the most anal and nasty about "safety" stuff on the ground, are absolutely dangerous when it comes to flying these things. Almost without exception, the guys that are the nastiest and most insistant are the worst flyers. I make a beeline for the shelter when a couple of the "safety" officers fly at my club field, and it's been like that in every club I've belonged to in my 26 year R/C career. Some guys need to exercise control over others.....

I am no Don Lowe, but I usually go home with the same number of unbroken airplanes (and fingers ) that I came to the field with.

I am never to old to take good advice though, and usually use a tail restraint nowadays, especially on the 4 strokes that need a minute or 2 to warm up.

These are all tail traps which don't help when you are using an electric starter to start the engine. Would love to see some contraception to hold the plane from going back when pressure of the starter is applied on the spinner.....

[8D] Well Said !

In fact , SO well said that I gave ya your first 5 RCU good doobie poster points for putting it so simply .

And to Tommygun , Look , buddy , it ain't about who is a "He Man" and can hold them self up in a stiff breeze , NOoooo , it's about the glow fuel slimy hand that one time in a million slips/looses grip and you end up with a ball sack full of spinning prop .

Most of us He Men are more protective of that than just about any other body part I know of .

PS , both safety AND laziness got the better of me , and I bought one of the pre made units from my LHS
