2025 Completion #3 - Curtiss XP-55 "Ascender"

Modelsvit 1/48 Curtiss XP-55 “Assender” (oops - misspelled)




Designed and built by Curtiss-Wright in St Louis (probably in the same building where I worked for MacAir). Three were built, two crashed. The remaining survived and is on display at the Kalamazoo “Air Zoo”.

The box includes a small PE fret, Masks for clear parts (inside and outside) and wheels, and decals. No aftermarket parts are available, nor are they needed.

Being a limited run kit, parts have no locating pins, and almost every prt has flash. Lots of flash – sometimes it’s hard to tell what’s flash and what’s part. Surface detail is very nice and construction is straightforward. Control surfaces (ailerons, flaps, rudders) are molded with the flying surfaces which further simplifies construction. The aft end engine cooling flaps are provided as PE. They fit, although I would rather have plastic.

The only glitch I found is that the canopy is about a millimeter narrower than the fuselage where they mate, creating a noticeable step.

Other than dry-fitting every part before committing to glue, construction was drama-free. Decals are wonderful, the carrier film disappearing nicely after application. Markings are provided for two aircraft: the second prototype (the surviving aircraft) and the third, which I modeled.

I made a mistake installing the main landing gear – they aren’t fully extended. I interpreted the instructions incorrectly.

The resemblance to Rutan’s “Varieze” is amazing: pusher prop, highly swept wings, vertical fins near the wingtips and canard control surfaces.

The XP-55 is a quite interesting airplane. Too radical for its era. Some general or politician called the airplane an ass ender when he saw it. So, Ascender it became. If I can find this kit at Modelpalooza, I’ll be bringing it home with me. A neat build for a “what-if” maybe.

How difficult was it to glue the cowl flaps? Did they bend easily to fit correctly?

Nice job! Quite a unique subject.

Very nice! I built the Collect Aire resin kit of the Ascender.

Nice work on the Ascender. Couldn’t tell about the landing gear, but since it’s a prototype, we’ll let it slide. :grinning_face_with_smiling_eyes:

Oh, look! Swept wings (before the 262).

fotofrank - the PE cowl flaps are a perfect fit. They attach to the plastic engine cooling fan, which then attaches to the fuselage aft end. I used white glue to attach the flaps after heating them over a gas stove and bending them around a 1/2" diameter PVC pipe. It was easier than I expected and the mess i made with glue can’t be seen.

As far as the “Ascender” name, Gerry Balzer credits Curtiss project engineer Bud Flesch with the name.

GAF - wing sweep is one way of providing longitudinal stability for flying wings. Even before WW 1 (yes, the first) Dunne in England built biplane flying wings using swept wings with vertical surfaces at the wingtips.

Thanks for the comments guys.

I always liked the look of the Ascender. Never built one, but maybe one day.

Hey, I used to work at MAC STL too. Also was building a Varieze, till wife realized what engines cost. Really into canards now, working on scratch Varieze 1:24 now.

Now that’s some history worth knowing!!

I built the Special Hobby (or was it the Czech Model kit?) kit of it about 10-15 years ago. Same basic format, limited run, none(if any) locator stubs, flash (but not too extensive), resin wheel, cockpit, and landing gear struts, that were soo wobbly after assembly I was afraid the slightest nudge would collapse and break them! Assembly wasn’t too bad, but it was different from a normal plastic model kit!
