Default Unknown Ultimate Bipe ID help needed

I acquired this plane via club auction this spring. Does anyone of you recognize the mfr of the plane? The wing span and length are both 56". It is unique in that the cowl and firewall start 4" ahead of the main LG position and the forward wing mount struts and cross brace are one piece of aluminum. The other unique part is that the main LG is composite not aluminum. I may be older as there is a tube down the fuse for a 72 mhz antenna. I am in the process of bringing it back to life but I need info on the set-up ie, CG, throws and maybe a new cowl. Pictures included.

cowl loosely fitted for reference.


My SPE 26 mounting fits perfectly


Front wing mount and diagonal brace is one piece of aluminum on each side and all are bolted into frame below

looks to me like an Airborne Models 120 Ultimate, although it may be an early version that was in kit form. not sure from the covering and the fact that it has a 72 MHz radio antenna run installed.

Close R3d ryd3r but unless the cowl on the early version was significantly different that's not it. The one you provided the link to has the cowl all the way back to the main LG mount. Also the upper wing mount structure is not the same and the upper wing attachment is different as well.

Wow, that's it!!! Now the real question is where can I find specs on the model. ie recommended throws, CG location is most important.

Did you get the information needed? I have one of these NIB and can copy the manual and send a PDF.

Advise and thanks.

Dick,
No I have not been able to get the data needed. I would love to have the whole manual in PDF but if its too big just the page(s), or just the data in a reply here with the set-up info on CG balance point (range) location and recommended throws on the control surfaces is minimum needed. Can you attach a PDF here or do you need my email address?

I will pull the manual for scanning today. I will try attaching to a new message as a "paper clip" icon shows in the reply. If that does not work due to file size will get your email.

Will get back to you.

Thanks,
