Some time ago, I put together a 29", WildWing Boomer-Lite, using a 10g outrunner, 6.5" prop and 2 cell lipo. At about 5.4ozs, it flew well, even had enough power to fly in up to 10mph winds. I flew it a few times and then it sat on the windy days, then I robbed the 10g motor for something else.

I have been wanting to try a 1700kv, 24g outrunner on a 2 cell to see if it would still fly good slow and then have a bit more speed for windyier days.
The boom spread was 7"s for a 6.5' prop, so I used a 7x6 and trimmed it a bit.
Since it would pull about 9-10 amps, I used a Enerland(Polyquest) 800mah 20C, with a 30C burst.

It flys very well! Zips around nicely and rolls very quick. It almost slows down as much as a 31.5" wingspan, but not quite.
The 29" wingspan with 7" boom spread is about as small as you can go and still use the servo pockets. Its just another keeper for the Boomer collection! Butch

I didn't get to get out yesterday, so I waited till I could take off from my chores for a bit this afternoon.
By the time I got to go, the wind was 18mph and gusty!
So I took my trusty 3cell 24g 1300Kv outrunner WW Boomer and the latest 2cell 1700kv WW 29" Boomer out to play with the wind.
The 3cell did fine as usual, but I was courious to see how the smaller wingspan, 2 cell, 1700kv would do in the high winds.
The shorter wingspan and higher Kv motor makes it alot more snappy!
It rolls alot faster, climbs vertical nicely at 80% power, loops and turns on a dime and still slows down and floats well. I had it float right on by several times, trying to land it close to me.
Its hard to judge the speed, but its alot faster than the 24g, 2cell, 1300kv on the 31.5" Boomer. It will fly just fine at 40% power and handled the gusty wind with no problems at all. Plus it came in with the batt just barely warm! Butch

This is still my favorite open field flier - wind or no wind!

56 seconds cut from 15 minutes of fun flying.

Really enjoyed the video. That's a heck of a good flyer. Nice.

A nice video! One of these days I need to figure out how to take and load good vids.
But for now, I have a hard enough time just building a few new planes and repairing all the broken ones!! Not counting all the ideas floating around in my head. Butch

Hey Butch,

How many times do those ideas cause you to make major changes in what you're doing and take you off in different directions?

Reading this forum's various threads I find myself coming to the conclusion that:
a. The fuselage is an unnecessary appendage that adds weight and drag to another wise efficiently shaped flying machine.
b. Change is impossible to avoid. Everything evolves.
c. For me building is probably more fun than flying.

Edit: Maybe version 5 will have booms???

Steve.

Hey Steve, you might be able to get version 2 or 3 to balance by making the motor cut-out deeper and moving the motor forward. Take a look in the "flying wing" forum and you will see a lot of the wings have deeper cut-outs for this very reason. I see in version 4 you tried a prop-in-slot. I don't see any reason for you to have any problem balancing that one. Murray

Thanks Steve and Butch - I put a little inverted flight in...like right before it zooms to the ground - which is up elevator

Steve - interesting build!

Butch - I've had a lot of fun following your boomer posts.

Hey Butch, Small world. If you get over here just email me at: steve_henshall@yahoo.com. I'll email you my cell # and we can text and maybe arrange an eyeball. I'm on Pangangan Island on the beach. It's on the west side of Bohol It's about 25Km across from Argao on Cebu island. If you have a map of the Phils our town is Calape. What island is your wife from?

The wing is ready to go now. I'm nervous about the glide tests. I posted about it on the KFm Flying Wing thread.

You ever put floats on a boomer? Here's a pic of my back yard.

Noggin Cam

Nice backyard.

What I use for my noggin cam for the videos is the strap from a welding helmet like in randall1959's thread noggin cam

If you don't happen to have a welding helmet not in use, try welding helmet accessory replacement parts like Jackson helment replacement parts - about $13. Mine's from an old Harbor Freight helmet.

I used a 1.5 inch "L" bracket, bent a little over 90 degrees, bolted on to the welding helmet strap, with an 8mm EPP pad double-sided carpet-taped to the front inside to pad the bolt head. Taped the L bracket so it wouldn't swivel.

The helmet strap is very secure and when flying you don't even notice it. Start the cam, slap the noggin cam on and start flying! There's no slop in the camera mount. The noggin cam ends up on your noggin the same way every time so no problems ending up with different angles.
