i'm thinking to extend the wings to make a delta and add some dihedral, what do you think?
You'd end up with something like a Cheap-N-Easy , which is a popular plane that flies well .

what i'm actually trying to do is just build anything that i can actually fly so i can practice takeoffs and landings, i built (well assembled) this one in the video but as you can see i hardly had it under control, maybe it was tail heavy too....

my goal is a long range fpv plane but that seems a little bit of a distance away right now

i don't want to try and fly the plane in the video again until i know what i'm doing, luckily i did not damage it beyond repair

Doing the math and using an online calc doesn't always get it right.

Long range FPV????

Best to check the laws in your country as it's very restricted 'everywhere'.

Most of what you see on the news is done with a commercial licence, lots of insurance and permission from those who control the skies.

Here you can get mailed with up to a $30,000 fine for breaking the rules.

If you want to scratch build a plane , I recommend starting with a proven model ..... rather than a self-designed model . There are several very good designs here in this forum , one is the Smart Dart XS .... here is the thread with plans :
https://www.rcgroups.com/forums/show...-Smart-Dart-XS
The Smart Dart XS is easy to make , can be scaled to any size , and is a very good model for practicing take-offs and landings . Here is a video of my 40" SD XS :



40" RC Dart (1 min 31 sec)





If you want , I'll be happy to recommend some others .

you just need permission where i am plus nobody cares if you don't do stupid stuff, are you allowed to discuss politics on here then if it's with reference to atc law etc

do you know anything about flight controllers?

If your in the US of A, the FAA cares. It's illegal to fly past your line of sight.

The reason we have so many restrictions upon our hobby is because of those who don't care.

how many deaths have been caused by drones/rc aircraft bringing down manned air traffic?

Unfortunately society tends to treat private individuals putting manned air traffic at risk in the same category as terrorism and thus needs to be heavily regulated to not only reduce the risk but also to be seen to be doing it.
The more publicity of individuals doing such activities the more pressure there is to regulate it or even ban it altogether.

so how many accidents have actually been caused?

Doesn't matter. The law is the law.

Take it up with the FAA.

I've put very basic gyros on scratch built planes a few times , and I've had two store bought planes with SAFE/AS3X . I have no experience with any advanced FC systems involving GPS etc .

For purposes of RC flying practice , a simple 3 channel plane such as the Smart Dart XS is all you need . A 3 channel plane with a high wing that has dihedral/polyhedral is inherently stable and doesn't need FC . And if you build it with low wing loading it will be slow flying . Slow flight gives you time to think , time to react , and time to correct a mistake .

Here is a video of a plane I've built with a high-wing/dihedral & very low wing loading , you can see how it would be easy for anyone to fly :




Lightweight 40" wingspan FT Old Fogey-ish (2 min 58 sec)
