Seems like you've chosen to test the BE under the worst conditions.....
here's some handy hints...
1.the CG should be at the location indicated on the plans...regardless!!!
2. the surfaces should not be warped....
3. the fuselage should be made of fairly hard balsa or if you like to crash alot ,even spruce...
4. If you're flying in a confined space...UP the size of the prop and reduce the throttle to fly slower....
5.Try to pick a nice day to fly until you get it trimmed out...
6. No nose diving into anything!!!!
Hope these help!!! It's difficult to test a new plane under adverse conditions ,and I think when you finally get things under control ,you'll like the plane............(and for all that ,looks like a quick fix on the airframe)...you have to remember ...this is a simple $2.oo airplane ...not a $60.00 P-51....if you do any bashing ,do it on this!!!!!
Granted ,the Frog is a most excellent flyer,but to compare the two is like comparing apples and oranges!!!

Since the wind and snow won't let me squeeze in a flight I keep tweaking my planes waiting for a chance to fly. I figured I'd post a picture of the finished Bullseye. If you like to build you just can't beat this. If you want to really stretch it and go all out with fancy hinges and graphics it makes a nice afternoon project.

Thinking of buiding another BE, however I'm tired of trimming motor sticks to fit the A sized motor. Do you guys use metric lumber or is everyone cutting standard lumber to fit? It would be nice to find a supply of metric lumber to fit these motors.

Another thing, after reading through this thread it seems that a bunch of different prop, battery combos were tested with this design. What is the consensus on the right prop for the job, or is the design receptive to all of them.


Lastly when flying this beast it seems that it would be beneficial if it was a tad bit nose heavy to keep the wing at a lifting angle. For a first launch should throttle be at full or half will a good shove get her of or will it fly out of your hand.

I use 5/16" x 3/16" spruce because it is almost exactly the same as 8mm x 5mm which is what is used on the GWS IPS gearboxs. Works great for me.

The spruce is a very odd size but you may be able to find it somewhere.

I use chopsticks for my DXA motor mounts, cause I didn't find any spruce at LHS and the chopsticks were free. I don't know what they are made of, but they are quite strong.

All I have to do is put some CA in between to make sure that the 2 sticks don't come apart. Then, since they are tapered I cut off about 2.5" to 3" off the front so that the tip fits the gb slot. Then cut the length needed and glue it to the fuse.

Isn't the bull'seye very similar to this:



The flying pizza box.

Ok... so mine is twin motored but it flies and it flies a little too wild too! Will hover easily and can take off vertically like a rocket (really fast!)

Only problem: Can't turn right very well. I hope to resolve this as soon as I can find a counterrotating prop (pusher prop) that's similar in weight and design to the GWS 1080.

Bull000...

The motor stick business is usually solved by planing down some thicker material to size ...I make several at a time ....
The 10x8 or 11x8 seem to be the prop of choice for the moment although I designed this to be a tame little float around donut" thingie" , things seem to have gotten out of hand ....wth FB Rich doing things reserved for much more specifically aerobatic designs....come on guys, this WAS just a $0.50 front yard toy in the beginning....PROGRESS!!!
Zeu...saw the pics on another thread , looks really cool and simple....tough to eliminate torque without CR props ...you might try putting a little right thrust in each motor....might help
Matt ... thanks for handy size ....write that one down!!!

I started a therad "Need help designing a micro Foamy UFO" and gpw stopped by and got me interested in the Bullseye. Here are some pics of what I have come up with so far. Still need to attach the tail, motor, and waiting on some more parts to get here from dubro. Cant wait to get this thing in the air.

is there a rudder in store for it....???

Looks cool and if you squint your eyes and get really far,far away ......it will look just like a normal plane ,schmaybe!!!
where is the motor going ??? I would think the CG would end UP somewhere around the Bullseye CG....good place to start ...first test glide will tell the tale!!!! Should fly really good!!!! please let us know how's it going......

Maiden flight yesterday.

Well.........not so good. Maybe it was too windy to test it.

Anyway, I've foam for a new one.....or maybe two!!

GPW: I've been thinking about the "bat" shaped Bullseye. I'll cut the foam this weekend and give it a try.

Bye,
