15 gm Lazer 200 w/Plantraco radio

Just flew my 14.8 gram Lazer 200 with Plantraco radio .Rudder,elevator and throttle.Motor is 7mm direct drive with one of Matt's props.Flys well but needs a little more dihedral.Made from a foam hand toss glider.(Tiger Co. is out of business)
Matchlessaero is correct -this aircraft is a Lazer 200

Thanks Matchlessaero - You are correct

Thanks you - I stand corrected as you are correct !!It is a 200 and the pilot is Leo Loudenalager, " Champion of Chamions" per the documents with the foam glider kit.They even tried to printed his name below the cockpit but it is not readable.
You have good eyes and knowledge!!
Thanks for the correction.

I don't know if this would work for measuring static thrust, but...

attach the plane to a scale with the prop pointing upwards and turn on the motor, then put standard weights on the scale till it reads 1 gram, subtract one gram.

Or attach the whole plane to a stick (the longer the better) and hold the stick at the other end to keep it straight but free to move up and down.
Take a piece of lead or something else heavy that weighs at least 3 times as much as the plane and alternately tape it along the stick until it's at the point that the stick stays horizontal. Do a little algebra to figure out the thrust.

I'm sure others have much better ways. I haven't tried these ways myself.

Doesn't look like a prophanger to me, but it sure does look like a nice little flyer.
Did you happen to trace the foam before assembling it? It really does look like it would fly well on ailerons and elevator.

Any chance of seeing your gear installation? It looks very clean.

I do not measure static thrust anymore. Stopped measuring static thrust several years ago as I found I usually had only 3 to 5 props that seemed to be the "looks about right to me " size. So I just check Gordon Johnson's data on small motors and bench check the current draw at 4 volts with several props and if reasonable go fly with one. Then change to different props in the field to see if I can find the best.
At this time the direct drive small props seem to be the following:
(Listed in no specific order)
1- U-80
2- GWS 2.5 X .8
3- GWS 2.5 X 1
4- AeroX blue prop (very small)
5- GWS 3 X 2
6- GWS 3 X 3
7- Several 65 mm black props - from B2 bomber and blimps

IMHO this is not to many to chose as direct drive usually seems best with props less than 3 inch dia.

You are right- It is a good flyer but not a prop hanger!!!
I did not trace the foam as I have several others I have not cut out.
Yes - think it might be better on ailerons and elevator-as the turns are somewhat flat-I hope to do that soon.
I do not have a camera that does good closeups; so will try to describe the installation.
1- motor is 7mm orange hopup from Toys-R-Us
2- prop is one of the 65 mm black "blimp" or "B2" or special "Matt" prop-all fly well
3-900 recr with battery attached are just aft of motor and against the leading edge of wing
4-Two mag Plantraco actuators under wing. Actuators first mounted on 3/32 square inch spruce stick about 3/4 ' long.Mounted at right angles to each other to provide centering.A hole and a slot were cut in the fuse with the slot just under the trailing edge of the wing.The hole was cut appox 3/4 inch ahead of the slot for the rudder actuator and the elevator actuator slipped in the slot.A very small brass screw through the fuse and into the spruce holds the actuators in place.The pushrods are .020 inch brass rod( Heavy but quick to build)Control horns are 1/32 plywood.

That is an great idea After seeing this thread I ran down stairs and
grab some depron and make an 11 inch wingspan Edge 540T. I am planning
to use for an motor is the hop-up motors that came with my ZipZap rc
car.My goal is to make an airplane this size fly 3d. This thread convinced
me to try it.

Thanks and great plane and thread


Edit: Question, is there any micro 4 channel recievers I can get out there
to use on my plane????

I getting close to the test flight I decided to go with an 3 channel.
I am going to use (ailerons, elevator, and throttle). I decided to use no
rudder. I have the motor installed and I am using 2 small actuators I found
hanging around in the basement including an reciever I found also in the
basement.I know it won't fly 3d ,but I hope it will do loops,rolls,fly inverted,
and ect....
