Help! problem with my first rc plane

[Houndpup Rc]

In the end i bought the motor you suggested me, i found a site that would have delivered it in five days. The transmitter is really intresting, I decided that I wanted to use my phone to fly the plane. I started with the integrated wifi antenna of my microcontroller but the range was not optimale. So i modified a old wifi router. Basically i drop it in the middle of the field and i get enough coverage to clear it. I tried my best to compress the size of the packet sent from the phone to the plane so latency is minimum and, given that i am sanding packet as fast as i can, i don't care about losing some of them. The comunication from the plane to the phone is a little bit slower but they are just data like battery voltage and gyro reading, i don't care, worst case scenario the attitude indicatoron my phone lag a little. In the future i will consider putting a nrf24 transmitter to use a physical joystick, i don't like much the feedback of the touchscreen

If you ever want to upgrade this transmitter work very well (It's the one I have, my brother has and @Mr Man has)
Here is one on aliexpress if you don't mind waiting a couple weeks:

Do you think is a bad idead to cut a hole in the under side of the wings, near the fuselage and cover them with paper? The wings are pretty wide there i don't think the overall rigidity would be compromised. Moreover the upper sheet of foam would still be intact. I can't think of other ways to reduce the weight. When i rebuilt it the second time I've already made evrything non structural out of paper. Or you think it's better to live with the extra weight?

hmmmm. It should be light enough as it is.....What brand of foam board are you using?

 

[Houndpup Rc]

In the end i bought the motor you suggested me

Cool! how many amp esc do you have? That motor will draw from about 30 - 45A depending on what prop you use.

Cool, I'd like to keep my DIY setup because it's really flexible, i can just code whatever function I need. Moreover I'd like to make some experiment and I really need the option to connect other sensors

 

[Riki10]

I don't know. Near my university there is this shop where we buy discounted supply. Architect students use it to build models, engineering students use it for planes or other things that needs to be light. So I'll leave it as is for now, no hole in the wings 🤣 .

 

[Riki10]

Cool! how many amp esc do you have? That motor will draw from about 30 - 45A depending on what prop you use.

Originally it was a 35 amp esc. Now it should be able to pull something more given that i had to fix it (too careless while experimentig). Guess I'll find out.

Here is the chart for that motor so you don't draw too many amps thru your esc

You are running 4S correct?

Okay just wondering....The best foam board for these planes is the adams readi board you can get at the dollar store, because it has the best weight to strength ratio.

Also it light than all foams board that I know of besides Ft's Maker Foam.

Okay yeah. Just because this one will have zero latency and you get at least 300 yards range.

Here i am, I've had a very busy week.
Unfortunatly in italy there aren't many places where you can find foamboard, I was about to abandon the project because of this... Luckly one of my friends was able to point me in the right direction and i took what they had. I didn't want to buy it online, I am sure it would have been destroyed in shipping.

I went with a 900mah battery 3s, one of my friends had a spare one from one of it's project and he lant it to me. If the plane works i will get one. I saw on the motor specs that it was intended to be used with a 3 or 4 s battery so i should be good. Moreover it should reduce the load on the esc, with my modification i fell good with drawing 40 amps, i don't want to exceed it. I will keep it monitored, I've even added a small thermal sensor on it (don't worry it's really light, my scale resolution wasn't enough to tell me it's weight).

Nice! Going are heading in the right direction now!

Hi, here is some updatese. The new motor came in yesterday. I ve tested the new electronic and is running great, the new motor is definetly faster (i might be a little scared after having lunched a prop flying in my room, anyway...). i ve also started fixing the plane, the fusealge is sturdy again and I've removed the broken wing wich as been difficultier than i've anticipated. Now i just need to replace it and than i will be ready again. Do you think there is something else i should check? I can't think of a better time to do so than now given that the plane lyes in peaces on my desk.

All wire connections, once you’ve got the wing on CG is very important.

 

[Riki10]

All wire connections, once you’ve got the wing on CG is very important.

I have the habit of reading quickly and sometimes i mess up, for a split second i tought you were suggesting putting the wings on before testing it and i was puzzled. Misreading apart, the CG will definetly be screwed, luckly i have a lot of space to move the battery inside the plane. I've read about it after my first test with the plane (I smashed the tail on the ground). The second revision had the cg on the first crease of the wing. Do you think it's okey?

 

[Mr Man]

Yeah I;d say start with the first crease.

 

[Riki10]

Yeah I;d say start with the first crease.

got it, let's put the wings back

 

[Houndpup Rc]

got it, let's put the wings back

Hope she works out for you!

 

[Houndpup Rc]

Make sure you don't have to much throws or its going to be REALLY sensitive.
