Mauricio it is well done! You have a viable component!Thumbs Up
How much does it weigh?

I just used a screened cox venturi, had to recover it back to the engine after the tests.

I wonder how much it weighs? My TeeDeeVooDoo's all up weight is 343grams and it plows the sky real fast:

343g is 12.1oz

Here is the statement Christian made about his plane:
https://www.thingiverse.com/thing:3457716

"Because of the COX engine being lighter than an electric motor with battery, the plane turned out to be slightly tail heavy.
I has do add 30g right behind the firewall. AUW is 380g now which is ok - should be no big deal for the COX Tee Dee."


Had he made effort to install the RX and battery behind the fuel tank he would have been at 350g.
I think he will most likely adjust the gear at some point, for now the test flight was great for a bit of speed
and acro. No telling what gear he used.

My Nano X with a tuned pipe is 235g / 8.3oz 3ch it takes focus in design and components to get to that weight.
My Nano IV hit 8.2oz / 139 mph without a pipe/header. I saved weight by building 8% smaller plane and used
new low weight metal gear servos.

Post  Dave P. on Mon Mar 25, 2019 3:31 pm

Correct me if I'm wrong Mauricio, but your venturi is going on the fuel tank vent, right?  I think Eric might be thinking it's going on, or as, the carb, in which case he has a point.  I would think that even if it's going directly on the engine, you could bore it out a bit to make up for the increased resistance to air flow.  

If it's going on the tank vent as a means of adding ram-air fuel pressure, I would think that it would probably be most effective at high speed when the engine is really turning and could use a little more fuel to keep it from leaning out.  I'm interested to hear how it works.

Your airplane is beautiful.  I thought it looked a lot like a Spitfire when I first saw your drawings too.  My favorite warplane.  Thanks for sharing!

Yes maiden flight Eric  RC Plane
Mauricio had seen my ram air effort on a 2014 project using a existing screened venturi from a .049 Sportsman.
It has inspired him to fabricate one for his project. I located mine to use prop blast for constancy if tweaked on
the ground the idea is the same amount of pressure in the tank will be maintained. Enough pressure is made to
have the engine singing throughout the run to the very last drop of fuel.

Dave, sorry for taking too long to respond, I appreciate your comment and help me understand Eric's message ... Thanks!
Yes you are right, it has a resemblance to the Spidfire, actually add some lines of Kim's model, the elliptical wing and look for it with old lines or vintage as Brad says ... finally it was very nice to my liking.
The decoration was thought when doing the steps.
I will be sharing the results of the venturi, so, here I will share as soon as I have news.
Thanks again for your time! Thumbs Up

Brad, considering your question about the weight of the model, here I post a picture.
The model weighs with the elements: 129 grs = 4.55034 Oz.
What do you think?

Hey Brad! I appreciate your attitude and I appreciate that you have shared it, surely there are more adept people who enjoy these very small models.
Making a Cox .010 speed is adjustable, is the real achievement for me and you have a lot to do in which I achieved it.
I was thinking about making some extra accessories of acceleration rings for .010, just for others to enjoy them, but it is clear that I need the cylinder of each one to make the correct adjustments and it is cumbersome all the process ....of sending me the cylinders. ..
Due to work, I have not been able to resume my work at PIYURIN 010, but soon I will have news.
I'm very happy with the result, I wish the flight was great! Very Happy  ... we'll see ... Huh...

P.S. I regret not having studied English, to communicate better! Rolling Eyes
