A few newbie questions

[SamB125]

I was just given a 2 meter R/E sail plane :D :D :D , the wing was sawed in half for transportation :eek: I want to be able to take the wing apart for storage and transportation It has polyhedral and some dihedral, could i just take the dihedral out so I can put in a CF rod? How does everyone here do 2 piece wings? And I have another question too, I don't really want to use a high-start because it takes a while to set up, so I was thinking about a 100 ft. tow rope that I put a loop on to put on the plane and then just run and bring up the plane then just stop running and let the plane glide off the rope, would that work? One more question, I have a couple3 cell lipos 800mah and 1300, what would I need to get so I can plug those lipos into the reciever? Thanks for all the help and sorry for so many questions :confused:

I hope you like building, simply put for a 2m model get 1/4 od brass tubing 1ft. long and some music wire that fit's inside it. Put a piece of tubing between the upper and lower inside area of the spar's, you want the o/b part of the tube to end at the inbd end of the third rib and the top of the bottom spar. The inbd. part of the tube should touch and go through the root rib as it touches under side of the upper spar. Now get a piece of 1/16th inch plywood that's overall a 1/4 inch bigger than the root rib drill a 1/4inch hole in the appropriate place and glue ti to the root rib. Now fill the cavities between the brass tubing and the spar's with thickened epoxy and your done. Phew!!!
hope that explaines it. Dave.

Do not plug the receiver directly to a 3 cell lipo!!!!! :eek: You wil fry the receiver etc... There is a solution, you will need a stand alone BEC to drop the volt down to 4.8 to 6 volts.... You can find one here

you plug th bec into your battery then plug the bec to your receiver. go fly....

Thanks for the replys, how do I keep the wing from separating in flight and do I keep the dihedral

If the wing is held to the fuse with rubber bands across the top, they will keep the wing together. Maybe a pic of this plane would help some of the design types here answer your question about the dihedral?

[scaflock]

Even thought he rubber bands are supposed to hold the wing halves together I still add a strip of electrical tape over the joint before mounting the wing to the fuselage. It's cheap insurance.

Only take out the dihedral if you never want to turn, and don't mind slamming the rudder around trying to stay upright.

For details of how wing rods work, check out the plans at:

This will probably be a little tricky. Take your time and think hard about what you're doing.

If you're going to fiddle, just get a 4 cell nicad or nimh so you don't have to get a regulator or anything. If you can solder the connector on, you can find these really cheap. 500 mah is enough. Of course you can always use a speed control that has a BEC with your lipos.

If you're launching by hand tow, you probably will not be able to fly it at the same time. However, if you have someone else pull, it might work. But it's tricky to get it steady, and it would be really easy to pull a glider apart unless it was fairly strong. THerefore it would be a good idea to use a weak link, I'm guessing maybe 10 or 15 lb test line. And you'd have to be prepared for it to break at the worst possible time.

Sam:

I doubt you can fly the thing and still pull hard enough to get any speed for a zoom climb. I'm afraid you might find that 100 feet of rope won't get you 100 feet of altitude.

I used to fly bigger sailplanes all alone, and a hi-start just wasn't that big a deal. Reel it out, pound in the nail, go get the airplane.

A hi-start has always impressed me as the simplest, easiest way to get sailplanes aloft - much cheaper than a winch, easy to set up for a specified pull tension, and all of my gliders launched hands-off (except the Hobie Hawk, may it rest in beautiful peace!). A hi-start well-matched to your glider, and you will get every inch of line on launch - vertical. Any breeze at all, and you can zoom even more.

Yours, Greg

What glidermang said and keep the dihedral. the Charles River web site is GREAT ! :D

heres some pics of it, thanks so much for all this help /Users/sambartell/Pictures/iPhoto Library/Originals/2009/Jan 24, 2009/P1040714.JPG/Users/sambartell/Pictures/iPhoto Library/Modified/2009/Jan 24, 2009/P1040716.JPG/Users/sambartell/Pictures/iPhoto Library/Originals/2009/Jan 24, 2009/P1040717.JPG
