The H on the crankcase indicates a Holland Wasp.

Thank you for pointing this out, I was aware that this could be a Holland Wasp but this was all I had to go on.

"The 1949 Atwood "Wasp" .049 was designed by Bill Atwood and Bob Holland. When they split up in the early '50's Bob Holland kept the Wasp name and later marketed as the Holland "Wasp." The Wasp was the first high-performance .049 engine.

The original Atwood .049 featured a heavier (stronger) crankshaft and larger porting. The tank was similar to the Wasp but picked up fuel from a hole in the left side of the tank rather than the low pickup tube as on theWasp."


I am still confused about the low pick up tube on this one! Maybe it is my interpretation!

A long time coming but I am finally sorting out the Atwoods. I originally posted the picture of what I thought was the Atwood Wasp but was quite kindly corrected.

However, I found an Atwood Wasp (I had one all the time) and here it is with the Holland Wasp. The Atwood 049s are not the easiest to identify but at least the Wasp and Wasp on it!

Ian, when you found the Wasp did it have a Dakota free flight attached to it. One of my flying friends lost one. We still chuckle about it although he still gets upset over it. We always said that we never seen a Wasp run so long on such little amount of fuel. Away it went in the great blue yonder. Ken

Afraid not! But 5,000 miles and the Gulf Stream would be a little much even for the most frugal engine!

There I was thinking the Dakota was a twin engine jobby and then I came across this.

Supposed to be for a small field and fly in tight circles! All my free flight models had a dethermaliser - never had one fly away but managed to set fire to one lighting the fuse! I've lost a glider though so I know the feeling.

Nice photos Ian.
I picked this Wasp up a few weeks ago at an r/c
flea market, for cheap. I think it might be an Atwood.

It is an Atwood Wasp. Just says Wasp 049 on both sides. That is the matching "Wasp" tank. The Holland Wasp is identical apart from the H stamped on one side.

All the other Atwood 049s have Atwood on one side but on all of mine - the top part of the A is missing.

Mark - rest assured - that is not an addiction problem. It is "a pursuit to completeness" brought about by "striving for collection completeness" Very Happy

You are very welcome! Laughing

I am an expert in diagnosing the phsycological attributes eminent in the most proficient collectors. I regard the use of the term "addiction" as an over simplification with a tendency to degrade the fine art in pursuit of a peculiarly postmodern pastime. Where collecting is simply the madness that makes humans human.

A collection is, after all, anything that merits being bought, received and brought home, doted upon, arranged, rearranged, repaired and held in personal esteem.

Engine collectors collect more than engines; they collect the knowledge (however banal or limited) that empowers them to take pleasure in those objects and to take advantage of someone else's ignorance.

Although the last remark may seem like a particularly negative expression but by collecting engines you join a group; by collecting only,say, Cox engines, you differentiate yourself within the group. In fact, something of the same dialectic occurs at the level of the object: a new object is acquired because it fits into the series but also because it doesn't replicate an existing possession.

When a particular collection is complete (if that were possible with engines) you can start another collection - compare and contrast, pass the knowledge gained, care and share!

After all, who would I be to declare anyone with a few engines an addict! Smoking

Here's a photo i did want to post, its a mint "H" Holland Wasp and according to the old collector i purchased it from, swears it's authentic.

It could very well be as the majority of 1/2a manufactures were anodizing their engines in the early fifties in an attempt to gain sales and i don't see why Holland would be any different, but I've never read or heard from anybody if this is true or not, so it could be just another "Black" Space Bug Jr.

P.S.
I took a photo of this engine years ago with my "new" digital camera and again the other night with my "phone"

Atwood definitely did it with red, green and yellow but to denote different engines. Atwoods are not the easiest to identify as they seemed to have a tendency to uses a mish mash of parts. Holland engines, I have seen no reference but who is to say what happened 60 years ago.

I think the coloured heads look superb, genuine or not! They add something to the engines.

A couple of those Atwoods look more like Shrieks than Wasps. Huh...
