Thought it would be good to make a thread with the most common beginners mistakes when building your first helicopter , so i thought id make a thread - maybe if its got some good things to watch out for it could get stickied for all newcomers to see, so here goes.. ill start off with one, add them in if you can think of more

- Double check the way your tail cog is assembled on a raptor 30/50. Althrough it seems like the thicker ring should go inside the other cog, it is not true. To check if it is the right way around, check to see if you can move the tail shaft into and out from the tail casing. It should not have any space to move fowards and backwards, only in a rotation.

Balance everything.....main blades, tail blades & fan. And don't forget to balance the main rotor head and tail rotor head while you're at it. It will make your learning experience much easier in the long run if you just take care of this in the beginning. Think of how many posts there have been about fuel foaming, gyro's not holding, servos failing, etc and sorting out the vibes solves most of these problems. If you don't have the balancing equipment, buy it...you need it! If you can't afford it, borrow it or find someone to give you a hand! Trust me on this....Your flying experience will be much more pleasant.

Don't use threadlock on screws that go into plastic.

Here's some newby boogers. Too much locktite. Improper gear mesh. Dry one-way bearing. Overtightening servo screws. Belt twisted the wrong way.

If God had meant for man to fly, he would have given him more money

Threadlock EVERYTHING thats bolts into metal, although just use a tiny bit.

R30/50: Check, double check and triple check that your thrust bearings are the correct way round on the spindle.

There are high point and blade balancers, i use the high point for EVERYTHING, rotor head, tail rotor, fan, main gears clutch bell etc, etc. If it rotates balance it, theres nothing as good as a smooth heli, and nothing as bad as one with vibes.

Buy a pitch guage, they can be bought fairly cheaply and make setting up much easier, DO NOT trust the guage on the frames of your machine EVER!

If you are not sure ASK, do a search on here, if that doesn't turn up an answer then make a post in the relevent section giving as much detail as you can, people WILL NOT mock you for not knowing, EVERYONE started at some point with no knowledge of model helis at all! If you still can't bring yourself to make the post, PM someone, i would say 99% of members will be happy to help you

Most receiver batterys supplied with radio kits are NOT powerfull enough to power a heli.

If you can get someone experienced to help, or take the model once built back to the store where you bought it from so they can check it over for you, there is nothing more disheartening than watching your brand new heli trashed withing the first minute of starting it for the first time. If you can contact the AMA/BMFA and find your local club.

Model helis are VERY HARD to fly, however with practice and a well built model YOU will be able to do it.

Running a motor lean will kill it quickly, if it's not running properly always richen it first.

Thats it for now

Buy a sim before the heli. It's a small investment compared to the possible total destruction of your new one.

Be aware of what's around you at ALL times when flying. ESPECIALLY for the first couple of times. I don't know how many times I've heard of new B's w/out a trainer get into a situaton, panic and go full throttle! It's not pretty. That being said, DON'T PANIC! Flying heli's is alot of fun!

I know.........It has nothing to do with the building of one but I thought it might help.

Always check your onboard batteries under a load of at least 1A after each flight, this will tell you if you have enough battery power to fly again.

Secure all of your servo connections!

My first crash was due to my battery coming unplugged from my voltage regulator... scary sight since I was in a wannabe death spiral when it happened.

Remember when flying inverted that down is up and up is EXPENSIVE!
