So to the rescue of an EZ BEE .049 r/c

Okay, so I couldn't wait to reset the engine, a little cleaning and checking.
So, the nylon plate on the fuel tank has cracks in the holes (I don't like nylon plates for this tank design), the tightening system has no stop and is often adjusted as it is disassembled. and assembles the engine, which at some point cracks the spaces for the screws. I tried with a brass antenna tube, and using an electric welder, embedding pieces in each hole, as a way of repairing the cracks, but it didn't help, it still leaks fuel, so I discarded the nylon rear plate.
Another .049 from Cox, lends him his deposit to be able to run and check the operation.
Place an AP cylinder cover with an AP glow plug that I had on hand, (I already told you that the original one from the engine was burned by an operator previously).
Then the engine starts and runs perfectly.
I decide to remove the tank and place a Surestar rear plate, with a Surestar air valve, but without the original rod, the rod in this case is a straight tube of our own manufacture, much shorter in length in aluminum alloy, it works perfect !
So I decided that the original engine of the EZ BEE model will now have a Surestar plate and air valve, which will be another engine destined for the Citabria. For the EZ BEE model airplane then, I will fit a Cox Babe Bee engine that I have in stock.

Thanks guys!...
Then I fly to the citabria post!!

After doing maintenance on the Cox PT-19 trainer https://www.coxengineforum.com/t18370-cox-pt-19-trainer ...I'm already getting my hands on the EZ-BEE....

and here I go!...













A special thanks to Roddie, about 9 years ago, he showed me how he controlled his engine and off I went!
Thanks Roddie!...you are a great person my friend!

Thanks Eric!
Let's go with the wing... I want it to be able to assemble and transport comfortably.
I make the pods out of wood with cooking thread and reinforcing cyano.
I make a solid bayonet from aluminum alloy.
A pair of 1.8 mm plywood ribs.
in progress...

Thanks Roberto!
Wing modification, now with bayonet!
Originally, this model comes from the factory to glue the semi-wings together, remaining fixed in a single piece. This modification allows the model to be transported and stored in a more convenient and safe way.

Flight!!!
Conclusion:
Certainly the design of this model is admirable. The polydihedron makes it very stable and safe, even in windy conditions. In those years, many hobbyists perhaps learned with a great model like the Cox E-Z Bee.
I cannot overlook the great quality of Cox products and for that, once again, to those people who were in charge of this COMPANY, all my admiration and respect.

Friends, first of all I share my feelings regarding what happened recently with the people in the presidential campaign. My thoughts for your people.
Eric, thank you for your comment, it is very easy and quick to assemble the sail, transporting it this way is very comfortable, everything turned out great!...Thank you friend!
Roberto, thank you very much!...you really went far...it's incredible how it climbs "without a motor"..there was wind, and the profile and polyhedron of the model did its thing...the result was surprising!!
Thank you for Argentina's triumph in football, I know there were some disorders among the people who visited the stadium, I still don't understand why sometimes people behave so badly, it's ridiculous to want to enter through the ventilation pipes of the stadium or want to enter. without having the entrance paid...well...I don't agree with that way of acting!
Roberto, Yes!!...the model flies with little radio assistance, it really flies alone!...it's great...this AM radio behaved safely at all times, there was no interference or loss of sign, everything perfect.
Making a projection to the sleeve of the main runway of the local airfield from where I am standing, we are about 500 meters away, I suppose then that only one point can be seen in the sky, without being able to see exactly the silhouette of the E-Z Bee , I estimate that it must have exceeded 400 meters in distance (0.24 miles)... I only saw an extremely small dot in the immense blue sky. ???

Eric dear friend, I understand what you are asking me, yes of course, it is a stage surpassed many years ago, this model is indicated for those who are starting out, it happens that I am experiencing something personal, there is a mental connection between my present and nostalgia, perhaps It is because my head imagines how many emotions were experienced at the moment of discovering the flight of a model airplane for the first time. At the same time, the story captures me, I am becoming partly a historian of pieces, I like to know about them, I I liked experimenting with this AM radio, and I also liked confirming the quality of COX products.
A few years ago in these parts, they did not have a good reputation, they were simply described as making you renege, that you wasted time trying to get it ready, etc., so, as I ventured into all these things, I realized that only It was about lack of knowledge on the part of the users, sometimes they did not have the appropriate fuel, sometimes the manufacturer's instructions were not respected through their operations manual, sometimes, some believe they know more than the inventor of the parts himself... .in short, there is some connection in me with these pieces and I can't explain it any other way, they simply catch me and I can't see them sometimes abandoned there, so when I can and one of these things appears, I buy it and try to buy it. restore them...bring them back to life or take them out of a dark corner to see the light again.
I don't know if I could explain it, but sometimes when I ride my bicycle through the countryside, I imagine flying one of these models in those totally natural places and it awakens a lot of inner peace and pleasure in me, a direct connection with nature itself.... .

Thank you very much friend!...this EZ-Bee is very good structurally, it only has the passage of time and therefore some of its plastics had to be glued and restored, but it remains almost original.
Yes, I saw the F1, original, it has a seat base for the engine with a great inclination to the right and downwards, it seems exaggerated, but strictly respect what is already done by the manufacturer and consider this experience to be very good , seeing the results.
It is very pleasant to fly the EZ-Bee, I think it is not only useful for learning to fly, but over time, it is a model that is useful for relaxing, enjoying a completely pleasurable, calm flight, breathing clean air and connecting. with nature, that's not an understatement!
Currently and to continue testing, I changed the original engine and installed a Bñack Widow, not because I need more power, but because its fuel tank is larger and I would like to gain more height...haha...well, it becomes interesting ...I haven't tried it yet, I'll see this weekend if the wind blows, maybe I can do something.
Thanks for joining in with your comment!

Mauricio I love the effort and this passion that you have, it's always pleasant to read and see the results at the end

Thanks for sharing your experience David!...the E-Z Bee weighs exactly 750 grams in the end, I don't know on average how much they would weigh but I estimate that those that come assembled as it comes from the factory will not weigh less than 680 grams, that is, with 2 servos , without bayonets and with the Cox Babe Bee engine, the lift achieved by this profile is excellent anyway, so I feel very comfortable with the 750 grams.
750 Gr = 26.45 Oz
680 grams = 23.98 ounces
Regarding passion, I appreciate your comment, sometimes it happens to me that I cannot see these models abandoned to their fate or that perhaps, their owner ends up throwing them in the trash because they deteriorate over time and as soon as I can I find a piece of these , I think about it and then I decide if I decide to undertake a rescue project haha...it is a nice challenge and it is very entertaining, even for many, you are out of time or outdated, which makes it even more interesting for me.. .no Everyone enjoys exactly everything that one of these pieces brings together, its history, its experience, its origin, in short...you get into the life of these things.
I think I'll now go back to my Citabria, which I put on hold between bailing out the PT-19 training U/C and the E-Z Bee .049 R/C.
