La Infant.......020/.030

Not wanting to nit pick and my French also being not that good,  I believe the correct French name is l'infant..French is a tricky language with nouns having genders, and infant as such is masculin, that goes with "le" whereas "la" is used with feminin nouns.

In order to prevent succession of two vowels between two words, the French abbreviates "le infant" to "l'infant"...sorry for my bookish nonsense..

Thanks Andras. My high school French does me little good in my later years. I just typed in "Infant" and hit "translate" in the WWW.....

My all time favorite - Mireille Mathieu........"I wouldn't hurt my little boy" mid lyrics.... I still get a kick out of it. The French, so passionate.

Never mind Bob...French is my hopeless love. While I was stationed in the Middle East some 30 years ago, as a passtime I went to the Institute Francaise for some language courses and what little I learnt there still sticks..too bad I am a lazy bum and should go
back  learning Frech further  instead of pitying myself

While I have no documented testing on this particular engine, from comments on this forum it wasn't particularly powerful.

I want to run one, along with about five of my other special/odd engines that I have mentioned here.

I also want to run the scratch built profile P-38 along with the Rene inspired tether plane. But, I have let time slip into cold weather and I don't want a won't start engine fight on my hands. Heat gun not-withstanding!

My time is dominated by clearing this land and the two newly aquired lots but I squeeze in computer time and fixing old engines and building airplanes. Some times during the day my feet never hit the ground. Time fly's and we are at the doorsteps of a new year. Hard to believe.

I can't visualize you as a "Lazy Bum" Andras. But if you really want to feel bad (like me) Mireille has recorded songs in eleven languages and is fluent in five. She is still active in her 70's.

Nice collection of Infants Bob, I’d like to get mine running one of these days too…. I’ve read that they’re not very powerful as Jim mentioned…. I think some of the old building plans had them interchangeable with rubber power …However a very significant historical small glow plug engine…. One of the first in 1949….

The Infant is extremely anemic. The .035 is pretty decent as long as you don't over prop it. We have a Ryan ST freeflight plane in our club with a .035 on it. The .035 didn't want to stay running on lower nitro fuel. It liked the 35% we offered it. Very consistent back to back engine runs and easy starting

Thanks Robert, I bookmarked it. Bill Mohrbacher contributed, Bill a long time and well-respected member here. Unfortunately we lost him a while back.

It would be fun to tach the .020 Infant against the Cox Pee Wee. So many engines, so little time. I'm thinking about making another mass ebay sale of alot of my duplicates to make room for a K&B engine corner. Infants, Torpedos, Allyns, etc. etc.

The cox PeeWee.020 would outperform the Infant .020. here is a review of the engine that I found in sceptreflight.

There is a review of the Infant .035 and Infant.049 there too.

I have a few Infants but haven`t used any of them. I also have a PAL engineering Infant .020 replica that should be better as it seems to be made with better equipment.  I like the looks of them. I was able to fix one nickel plating the piston using an article I read on an engine collectors magazine. I like the looks of the little engines. When they came out AMA created the 1/2 class.

Yes-some kit instructions used to read 'Use 4 strands of 1/4" rubber or one K&B Infant'.....

Didn't see an infant review on Sceptre Flight Engine Tests, was somewhere else. It falls a wee bit short of the Pee Wee.

Pee Wee's dual intake bypasses was like a miniature Black Widow, why it outdid some earlier .049's, became the staple for Pan Am PAA payload duration contest free flights based on plans of the era and of course, early quarter-A R/C single channel flight. Ken Willard, Dick Kidd and others, their plans in various modelling mags of the time were featured.

I remember the ads in America's Hobby Center for a $40 single channel escapement transistorized super-regen radio system, add another $7 or so and with the radio get a T/F Ken Willard R/C Schoolboy with a Pee Wee engine.

Searching on the Infant, MECA has a multiple page PDF that includes ads and photos of the time about the Infant.

Seems there were designs for it, F/F and C/L back in the early 1950's.

That would be an interesting comparison of its power.
