Hi

I am unable to successfully complete a maiden flight for the FT Nutball that I made using coroplast. Wanted to know how many props did you guys break before your first flight?

Already broken 7-8 and counting...

We all have broke a lot of props.

First of all,use Prop-savers
secondly use APC or Electric props , rather than thin orange props.
Thirdly  Check CG. Correct cg is most important.
get in touch with some experienced flyer,you will learn much faster.
If you are starting in this hobby, better choose a pusher plane, learn on it and then you wont break much props.

If you do not find the reason for your crashes and resolve the issue you will keep crashing. Better to contact an experienced flyer around you. Where in Delhi are you ?

Kaputt-In german it means Break down!!!
Really man, okay, jokes apart. nutball is a damn good plane when made in foam, the CG shifts way back if you make in in corro. how do i know? i make it in both and had the same problem. though there might be lot of other reasons with yours, this is the first you should be looking for. please post some pics/video or atleast describe how you broke somany props, make your basic checks and let us know where you went wrong.

Sorry guys, I couldn't reply sooner as I had my exams going on.. Thanks for your quick replies..  

@manojswizera Glad to know that!
1. Will get Prop-savers
2. I am buying props from hobbyking.com. From where do you get your APC props from?
3. CG is Correct (it is about 5 inches from the front)
I am still searching for an experienced flyer. Also, I am thinking of making a multi rotor  (as it might be easy to fly and difficult to break props)


@allthatido
I am located in NSIT Dwarka Sector 3 (most of the time)/ or for the holidays at Krishna Nagar (East Delhi)

@v2 eagle
For the 19" Nutball the CG was at around 5-6" from the front of the plane.
I broke first 2 props flying in small places( first a basement parking lot second an indoor badminton court) because i saw videos of people flying a nutball easily in small places on YouTube.
Second thing I realized was I had chosen the wrong props those were 8060 props. The 6" pitch causes lot of instability. Which I initially felt and then later read
about it. (By then I had broken all of those props, around 6 of them) The 8043 I used next were much easier to control.

Another thing I learnt was I did not balance any of the props and/or use prop savers. (which should be a must for beginners) Could not place an international order just for a prop saver, so was trying my best to fly well!
And till now I have not been able to make a nice landing gear (Would be ordering that too now). So the hand launch technique also added to some unstable control for a beginner like me.

Where do you guys get your stuff from?? There are no such hobby part manufacturers in India?

Will post the pics soon..

This is not completely true and here I am speaking from experience. Props are the first part to break in a crash and prop savers are not an option if you are using multirotor specific motors that have short shafts. I have broken several props (more than 8 I think). I have had one prop break in mid air, flipping the quadcopter and breaking all the other props. It is easy to break props even if you nick an object. From my experience, multirotors are not that hard to fly. I got started in the hobby with a quadcopter and I am going for a plane now. So far, I have not had much trouble flying it though it has been grounded for a few days after I lost a prop nut. However, multirotors are much more expensive to get started in (generally speaking). Another big bonus of multirotors is that they generally need less space than planes.
