these were the ready to fly planes during my early teens. There were the cox engines too. The flying wings were the rage back then too. It was a hassle how many large batteries we used up starting these engines and the fuel was made by wenmac or cox. We lived in the Philippines back then and all these were imported, and pricey. But we loved those years we flew these toys.
I grew up on wen-mac back in the very early 60s,late 50s.had a P-38 with twin wen-macs,u control
I wanted the p38. By the time (1970s) I could find one, it had the crappy testors engines. After the testors p63 I had couldn't get off the ground, I passed on it. Did your p38 fly?
Ive finally got around to testing my collection, ok cub and testors/macoy/wen macs have been super easy to start
Dave if you want to get needle valve straight as possible , mount a pistol drill in a vice or clamp it to a bench and place the needle valve in the chuck.
This will allow you to rotate it slowly and make small adjustments with a tube , like a spare small 4 sroke pushrod cover or brass tube.I had one of these in the 1970 s, they make a real racket , most sure to upset the neighbours
I might try that, but in reality I think I have it pretty straight now. Thank you for the tip!
I had a red '57 Chevrolet drag car powered by the Wen Mac .049- it had plastic drag slicks and spent more time trying to get traction than it actually ran, but if you ran it into something to get it stopped , it usually broke things( all plastic and flash plated chrome parts.) It was scary fast if it ever gained traction !!
I have a few of these and I just took it down as far as you did and dropped the rest of the engine in some old fuel for a good bath !
Have you ever run yours? If so, how did it run? What prop size do you use? I just put a 6x4 or 6x3 wood on this one. I just need to fabricate a wood mount for it.
David these engines were designed by atwood for A M F who made them by the thousands. MK i MKll and Mk lll.a good little .049 uses same piston and cyl. as atwood .049. got a dozen in my collection of over 800 model engines.
In 1966 and 1967, Wen-Mac produced 1/12 scale promotional scale models of the Ford Mustang GT for Ford dealers. These plastic models came with battery-powered electric motors, but they offered the option of an .049 engine to power these cars for around $5.00 extra. I'm wondering whether this (obviously a model plane engine) was the same one that powered those Mustangs?
My Uncle gave me one of the WenMac powered Mustang tether cars, for my birthday, and that version of the motor was a bit different as it had a round "throttle", that did not modulate the input gas/air, it modulated the exhaust port. This was part of the tether system and had a string connected to the car that controlled the speed. It was noisy, slow, spewed gas like an EPA Superfund site...it was extraordinary fun for me and my friends. I never had any issues running that engine in a variety of models once the Mustang met its doom in an ill conceived jump. It flew in some airplanes, but mostly cars in a straight line tether with the throttle pinned on the chassis. I likely still have it somewhere in storage. It was unique in that it had a gearing system to drive an axle, or in one case a giant slow propeller for a balsa and tissue airplane.
Yeah I did run them and they are ok not as good as a team Cox but still I good engine! Make sure the ports are not to rough ie sharp!
Wen Mac engines are very crude compared to a Cox .049. I bought a Wen Mac plane in around 1963. My Dad and I could never get it running. Found out later the fuel line was disconnected from the factory. It never ran.
Actulally, they aren't bad at all. They are another product of the design genius of the late great, Bill Atwood.
And as for the prop size I used the same as the 049 cox
Hey Dave, can you briefly describe (or point me to a video of yours ) on how to use the "LA Totally awesome cleaner" on engines ? Dilute it ? Proportion ? Time to submerse ? Any feedback woyld be appreciated. Thank you Dave.
Whatb was that cleaner you used to remove the crud? thanks, Carl
Carol - LA Totally Awesome Cleaner was used. It is available from Dollar Tree and it is a totally awesome!
I had a control line P63 from testors. This was after wen mac was sold to them. Also had a rudder only r/c plane. Both had the testors .049. No power. Very disappointing. Neither would fly.
Very low run time
Should do at least 14K on 25% with a 5X3
Run that puppy
