Main blade bolts for 450 pro...pulling my hair out!!!!
Ok... My heli uses m3x16mm socket collar screws ,BUT I CAN'T FIND EM with out buying new blade grips etc.... I want to know how bad is it use standard running thread for a pilot who doesn't do 3D. If I have a high grade bolt will that work??? It seems like every kit out there, even one specifically for my heli DON'T come with collared screws. Help guys(and girls)

Trex-450 upgraded bolt part number HS1195 (M3 x 14)found here ($1.99 in stock)(or do a google search and buy from whoever you like):
http://helidirect.com/align-main-bl...rade-p-4196.hdx
Or if you want a little longer bolt (M3 x 15) that has a shoulder and includes 4 of them (I like these myself):

....and you don't want to use a full threaded bolt for blade grips regardless of the kind of flying you are going to be doing.

If there is any part on a heli that you don't want to compromise, this be one of them.

Thats what I keeps hearing, but WHY is it so hard to find them then???? Also, I see companies like helidirect selling full threads as blade grip upgrades???What gives? More resources please. Thanks

And another thing, Why do I see other types of heads with running threads on there grip screws??? Whats the problem with running threads if the blade grips are plastic??? Are the screws weaker than the plastic blade grips? What gives? Not trying to be an a$$, but I'd like some reasonable explanation to thisMy heli's a submarine hybred. (I live in Washington)

The threads weaken the strength of the bolt. The bolt needs to be shanked or "Shouldered" the length of the bushing. Over time, the threads will eat through the bushing and then the blade root can be compromised.

Your well being is what I am considering. You wanna do it, have at it. But don't point fingers when you throw a blade......450's spin very fast and the blade is a weapon when it is released. The object of this game is to reduce risk as much as possible and preserve limbs.

I am a firm believer in Darwinism, so like I said before, you wanna do it, have at it

Experience is my resource................

Jolt,

It wasn't a personal attack.I also understand running threads are weaker. I just want to know some head sets use running threads. As far as resource... I was referring to suppliers, not your experience.Hope we can still be freinds

I finally found collared screws at the hardware store, but they were like 30mm or something. I cut them down with my dremel and weighed them to make sure they were identical weights. The collars were the perfect length. So now I'm happy.
