That is the issue. I bought an ultralight after seeing one picture of the engine and no pictures of the airframe. I only paid $300 so I figured, how could I go wrong. I think I got a great deal but I went to pick my purchase up and found that I couldn't tell you without more info what motor or airframe they are. The airframe has a folding wing, not like a paraglider but a wing that fold for storage and transport. The airframe has other features that were fairly distinctive such as larger bicycle type tires @ about 12" and a seat that just floats with only the front of the seat an the back top of the seat attached. The other distinctive feature is there are a ton of fine cables that run from the wing assembly and the supports for the wings that are spaced out under the fabric on the wings that creates the shape a wing needs to create lift. The final feature that convinced me that it is an Ascender is the unique panel the is attached the front of the airframe. Anyway, I have researched as much as I can with the limited info, and this is just a guess, but I believe the airframe is a Pterodactyl Ascender and if I am correct about that then I believe the engine that was used at least for a while with the airframe was a Cuyuna 340 D or the 430 D and I say that because the engine I have is a direct drive if I understand the meaning properly. I would appreciate any and all information that anyone could help me with as I am a newbe but am very interested in learning as fast as possible and so I can get into the air as safe as possible. To be honest with you I'm not sure that the set-up I have, even in new condition, would be for me as it seems very complicated to assemble a probably to fly. I would much prefer a Weedhopper, Quicksilver Mx, or even a or an Aerolite 103 but due to being disabled and having a limited income I have to work with what I can afford. Ultimately, I would like to build an Affordaplane but that is in the future. Like I said I would appreciate any and all information about my new addiction and I thank you all in advance for your input and help.
