Wing building tips, tricks, advice!

I'm board, just figured I would start a thread for the advanced wing builders to post their Tips, Tricks, and Advice on building wings along with electronic set-ups, pictures of wings, and your opinions of who has the best wings!


Here is the first question...Which is best to start flying a wing with, brushed or brushless?

I'd say brushless, because as a beginner, I know I needed that extra power that the sp 400 on 8 cells couldn't give.
And it is pretty hard to smash a motor in a standard flying wing.

I agree with Daniel G, GO BRUSHLESS.
Pictued below is my Zagi 400x 48" wing running a 150 watt Brushless Outrunner powered by a 3S 4000mah LiPoly. Zagi AUW 28 oz - goes vertical running a 9x6 APC prop.

Don't buy a zagi is a good beginning.

Don't allow the "That little bit of tape won't add much weight...." mentality to get you!

Here`s a tip from a newbe. Take your time!
My first Sickle was built in a day and flew like it.
My second Sickle took two weeks and flys like a dream.

Use a small router or a dremel tool as a router to route out the servo, rxer, battery compartments. Also with a straight edge to route spar slots.

Pot you servos with epoxy - i.e. after you cut the servo compartment, wrap your servo in a plastic baggie, spread epoxy in the servo compartment and bed your servo in the epoxy. Once it hardens, pop the servo out and your servo should pop back in with no slop. A dab of goop will hold it inplace.

On a large wing use standard size servos. They're cheaper and are stronger than the little light weight ones. They stand up to hard hits on the ground of in combat. It sucks to have to dig out a servo after a crash.

Keep you wing beds. Use them to protect your wings while not flying.

Use thinned goop on the nose and leading edge to keep the EPP together better when you crash.

Nip the excess control horn screws so they dont catch on something and break off or dont scratch you when you try catching the wing.

Bury your rods.

Once you get the thing flying, move the CG back to reduce the elevon reflex till its almost gone. Keep moving the CG back and if you have to reduce the Elevon ATV (if it gets twitchy) till you have little or no down elevator when inverted.

Make sure the elevons are even and move the same distance up, down, left and right (symmetrical).

Mount the control horns so the holes where the control rod clips to are directly over the hinge line other wise you'll build in asymmetric throws.

Dark color on the bottom, light color on top.

Dont be a wuss when you throw it for the first time (like me). Give it a good throw so it gets good flying speed.

If you've never flown the wing and arent sure, let some one with experience trim it out for you. There is no shame and you'll learn to flyit faster and better.

Make sure your channel is free before you turn on your TX. I didnt once and I shot down someone else plane. Good thing the other guy was cool about it.

Turn on you TX before your plane and turn it off after you turn on your plane. Dont want stray RF to turn you motor on.

If in doubt ask someone. It'll save you time in the long run.

Have fun.

I thin goop with xylene...available at most good hardware stores and Home Depot's around here....The stuff I use is Ace Hardware brand. I understand Toulene works as well. Do a search for "thinning goop" and you''ll find a lot of good info--like the link below. BTW, I recommend you use a respirator when thinning and working with goop. The stuff is pretty potent. Don't thin it in the kitchen... I have a slope version of the sickle and it flies rather well. I'm anxious to see how yours flies on the BM-21.

Great! I like the idea of thinned goop on the LE would make it stand up a little better! As far as my build Im in no hurry as I dont have any servos or receiver for it yet I think im going to go with HS81's and electron 6 am I right in thinking that 1750 KV is 1750 rpm per volt?
