    Around 25% Ultimate Bipe, which kit was that?

    I seem to recall there being some sort of Ultimate Bipe kit that was around 1/4 scale, maybe it was closer to 1/3, which kit was that?

    Was it this one?

    I've been thinking about getting this one for myself. I think a 46cc Poulan chainsaw engine would be perfect for this one.
    Airplanes have expiration dates. Its just not printed anywhere on them.
    Im not really an airplane pilot; but I did stay at a Holiday Inn Express last night.

    The Goldberg kit of the Ultimate works out at about 25%.

    No way is the Goldberg 25% since I don't even think the DP is 25% and its bigger, same with the Lanier. The problem I have with all 3 of those planes is there is no good powerplant for them. Any decent sized gaser is too large and would _destroy_ the cowl, and any glow is either way too big (Moki) or _way_ to expensive YS 1.40 DZ and they all suck up $15/gal glow like it was free. Turns out the plane I was thinking of is the Ohio RC 33% Ultimate, I need me one of those.

    Goldberg wing span is 54 inches. Times that by 4 and you get 18 feet.

    Full size ultimate has a wing span of 18 feet.

    Therefore Goldberg ultimate is aproximately 1/4 scale. (obviously this ignores other factors such as length, wing area etc).

    Check this link for info on full size 10-300

    (PS I didn't beleive that the goldberg kit was 1/4 scale either till I found this site when looking for info and colour schemes)

    Incidentally if you use wing span, you get the following for 1/4 scale:

    Zivko Edge: 73 inches
    Cap 232: 73 inches
    Extra 300S: 74 inches.

    I have seen wingspans for "quarter" scale planes between 68 and 78 inches.

    However, these are all within the 10% limit for IMAC, which does allow for a certain amount of leeway. Probably just a case of kit/artf manufactures rounding to a nice sounding scale.

    Well dang, I guess they are 1/4 scale, they just seem small (esp in the cowl). Turns out I was thinking of the 33% Ohio RC Ultimate. I want to be able to cram a whole gasser engine into the cowl w/only the exhaust sticking out and I think thats the only ultimate that I would be able to do so. Not that I'll be building it any time soon, still workin' on my Extra

    If you are looking, and can find one, a Great Planes Christan Eagle, you can get a 50cc in the cowl and all that is sticking out is the exhaust pipe.
