Could I have 70mm beta plan? I'll test it.I don't know yet, @Zephyr1 is testing out the design with a 70mm EDF fan, last I knew he was ready for his maiden and his radio stopped working. If you would like the Beta plans for the 70mm EDF version I can send them to you.
There are no tiled plans, but you can still tile them if you use adobe reader. You can just open up the plans in adobe reader and select print. After the print window opens up there should be a section in the middle of the window labeled "Page Sizing & Handling" right below that there should be options to choose between "Size" "Poster" "Multiple" and "Booklet" You are going to want to select the "Poster" option. Next, ensure your tile scale is set to 100%, your overlap is set at 0.005 in. and that you have the "Tile only large pages" option selected. You can also select "Cut marks" which will make tiling the plans after they printed easier, but it will increase your page count. Lastly, go down to the bottom of the print window and click print.where can I get tiled planes for the 50mm edf vertion
If i may ask, why change the wing tips, I love the tanks. I was even considering adding "Bombs" under the wing. This will help when landing. Then you not landing on the wing itself.
I like the first one.
No problem manSorry, wish I would have thought to take more.
That looks really good!!!
It's hard to test how much thrust an EDF is producing unless your flying because you need lots of air going through the intake.
I think your build is too heavy the wing loading is already a little high so I don't think it will be an enjoyable experience to fly with the extra weight.
On the bright side I know my Grunjet flew fine using a 4s EDF with a 3S battery, so it was putting out around 500g I think that plane might suit your foam a lot better...
Honestly if it were ROG (tailing off from the ground it would be OK. Most business jets have less thrust than the weight of their fuel loads (citation X+ has just under 15000 pounds of thrust with takeoff weight around 36000 lbs). But this is hand launched plane and thrust rules.Hey Grifflyer,
I am 95% finished. But now I have doubts. I got a 50mm EDF motor that the website says give 480W continuous power. It can give 800g of thrust. I tested it now in the L39 with thrust tube. I get 385W of power and when I put the L39 upside down on a scale that has been zeroed I only get 398g of trust. But I do not know if this is the correct way of testing an EDF setup. I have never had or flown an EDF Jet.
Like I said in other post, we in South Africa do not get the same foam board than the guys from Flite Test. So, you said your plane is 340g dry weight and 482g all up. Mine is 520g with servos, ESC, EDF and RX. No Battery !!
So, can you guys with the experience say if I am under powered please.
Pic's below is 95% done plane, need to neaten up where i glued the top peace and H&V
I added the flight compilation to the first post!!
Please let me what you think of it and where I can improve.
OK, all that is left is to verify motor turns the correct direction and glue on the wing.
