Information please.

Hello everyone,

I had acquired a few airframes from an estate a couple years ago and need some help in identifying a sailplane. This particular one has a wing span of 98 1/2", the cord at the root is 9", the fuselage is 49 1/2" and the horizontal stab is 32". I am attaching a few pictures to this post (hopefully this works since it is my first time uploading pictures). The wing and the stab are both held on by elastics, whether or not this was by design I have no idea.

I am also attaching a picture (trying anyway) of the radio gear that was in it at the time to hopefully help out in identifying the approximate time it may have been in service. The receiver has a frequency label of 27.045 MHz.

Thanks in advance for any help you can offer.

Greg.

P.S. I will most likely offer this up for sale but I would like to gather as much information on it as I can so that any potential buyer will know what they are getting.

Here is the Radio equipment that was in the sailplane.

I'm guessing maybe a mid seventies Airtronics model Super Questor, but the fin does not look quite right, maybe modified?

Na, on second thought, the whole tail looks wrong.
I'd guess it's a 70's airtronics though.

The servos date it to the early to mid 70's. I remember those linear drive servos and they didn't last very long. I also believe its and Airtronics glider but can't remember the name.

It does indeed have an airtronics sticker with an ellipse and an elongated arrow (more like a boomerang) inside it. I thought it must be an older model based on the electronics inside.

Thanks for the replies guys.

Does anyone know if the stab being held on with elastics is designed into the model or must it have been a modification by the builder?

I could be an Olympic 99 the predecessor to the Olympic 2. If so, it is a real floater designed for 6 volt winches or regular strength hi-starts.

The elastic wing /stab mounts were probably designed that way.
The radio is illegal for use today incidentally and not worth trying to modify if it is even possible.
Those linear travel servos solved a lot of installation problems at the time and I have often wondered why no Mfg makes one today.

Just a side note:


Kevin, I have seen a replacement top part for modern servos the turn the servo into a linear style. The part you replace is the top gear cover. You simply remove the standard one and screw on the linear one. Can't remember where I saw this but I know it exists for the modern servos we use now.
