 Posted: Mon Oct 01, 2012 3:57 pm Post subject: Parking brake alternative - now including towbars |
 |
|
I've been using my Bogi-Bar (04M -RV10) to do the same thing
http://bogertaviation.com/index.php?page=shop.product_details&flypage=garden_flypage.tpl&product_id=3&category_id=3&option=com_virtuemart&Itemid=23
I haven't modified it at all up to this point. With the bar collapsed, I jam it into the bottom of the pedals and the front of the bottom seat cushion. It has stayed in place so far but I'd like to add tabs to it that would fit into the rudder pedals.
What I envisioned for tabs however, would not necessary still work if I re-positioned it to the top of the brakes. So I'm wondering, 1) are you using a Bogi Bar? and if so, 2) where do the tabs go? I'm curious not because I want to actuate the brakes but because I don't think I have a clear idea of where the tabs go and how they work.
BTW, for awhile I was snaking the control stick up thru the Bogi Bar so as to get some elevator and aileron locking. It seemed to work but I never really tested it to see if it was firm enough to prevent any kink of 'flutter' that may occur in higher winds. Now I just push the stick over to one side. I'm thinking of adding a strap to hold the stick so that the elevator and ailerons are also secured. Anyone doing this? Thoughts?

There is an on-going thread about whether or not to install a parking brake. I did not, but I can offer an alternative:
I put tabs on the front of my tow bar, as suggested by others, to use it as a rudder gust lock. (tabs keep the bar from falling off the rudder pedals; handle of towbar is against the seatback; lap belt holds it down.)
All you need to do is move the towbar up so it pushes on the right seat brakes. I can do this while holding the brakes from the left seat. Yes, it does require pre-planning, so the towbar is within reach.

Yes I have the Boggert bar.
Tabs: If you visualize the bar attached to the nose wheel, the tabs are on top of the bar, protruding aft, beyond where the bar turns in toward the nose wheel. I just used some scrap aluminum and a couple of hose clamps on each side. I know some have welded them on. The tab goes over the rudder and under the brake (unless I'm using it as a parking brake, them the tabs go over the brake pedals) and keep the bar from falling down if the pedals move a little in the wind. I use the full extension against the seat back. Due to the slope of the seat back, as I pull the lap belt tight around the towbar it makes the towbar push forward, against the pedals.
I put some foam pipe insulation around the triangular opening in the towbar, just before where the handle pin is. I insert the control stick thru this opening, the foam provides some padding. Then I use the lap belt for the other front seat to pull the sticks aft, against the padding, to minimize movement in the wind.

I welded two small tabs on the tips, as described by Bob. It works fine. I move the stick to the side, jam the collapsed tow bar against the bottom cushion, and bungee the stick to the tow bar.
It's been suggested to me that I slip it over the stick and jam the extended tow bar against the back cushion. the seat belt would definitely make it more secure. The only doubt I have is the tow bar pushing the brake pedals enough to "slip through". Also, locked brakes would complicate things if the FBO needed to move your plane.

If you extend the handle and go up to the seat back you'll get a better angle on the brake pedals, making it less likely they'll slip up and over.
I only would use this long enough to get the wheels chocked. Then I'd go back to the rudder bar/gust lock, where it cannot easily slip out.

.063" X 1/2" X 3/4" steel tabs tig welded to end of bogy bar. Fits in slot under pedals. I insert collapsed tow bar in front of lower seat cushion then adjust seat forward. I tighten my seat belt around stick with an article of clothing to cushion. Nothing moves and minimal weight added.

I have a bungee to hold the stick in place:

FWIW, we're on our third Bogi-Bar in five years. They keep cracking at the flex point. To their credit, Bogert replaces it no-quesions-asked, and last time they said it had been upgraded to prevent the same cracking, but I can't see any difference. Still a great product.
