All, I recently upgraded my blade 400 blade grips to the aluminum grips. The stock grips allowed the blades to have a certain amount of "flop" and the aluminum ones does not. As a matter of fact they are wedged in there pretty good. Is that right? Shouldn't there be a certain amount of give with the blades?

Others correct me if im wrong but the grips on any heli should not have slop or wiggle so i would say its a good thing. Unless you got wierd tail grips like i do that tighten up under load.

Tight without slop is good. I'm not sure how "wedged" in you are referring to. They shouldn't be wedged to the point where it feels like they are binding during movement. Suggest disconnecting linkage and checking their freeness of travel.

I had the same thing on my b400, just sand down the thickness at the root of the blades a little.

Yes, they are definitely not moving freely if you try to manipulate by hand. I can try sanding down as suggested. I am using the stock blades. Should I be using a different brand of blades with the aluminum grips?

shouldnt matter what blades. Lets get back to "No smooth movement". The grips should have no slop and move freely. Did you forget a washer ot something in the grips? Did you overtighten the spindle shaft screws?

To clarify, the grips themselves move freely the blades however do not move freely within the grips.

Blades shouldn't really move freely. It should be able to move, but not so lose that it moves freely.

Are the blade roots hittin anything? If not you need to tighten them just just enough so when you tilt your helicopter sideways they do not fall or move. They should not be swinging or very easy to move.

Ok, thats what i wanted to know, the guy at hobbytown told me that they should not be "too tight" and I wasn't sure how tight is too tight.

Thx

Easy test that works for me. Point the blades nose to tail. Hold heli on it's side and the blades should not fall on their own. Give it a little jerk, up/down while it's still on it slide and blade should fall a few inches. If they fall on their own or fall where they want to touch, still too loose. if they don't move or move an inch or so, too tight.

Ok so I did as you recommended chamler and the blades don't budge. Tried without any screws in to hold the blades either and they still don't budge. The aluminum grips definitely has less room than the stock ones.

K. Not sure what blades you're using but I'm assuming stock b400 blades. Ones I had, had a plastic triangle shaped spacer screwed on the end where they insert into the blade grips.

If yes, You'll need to remove those and see how they fit then (might work, might need a spacer a little smaller then the orig plastic one).

If not, try what max232 mentiond on sanding down at the root.

Any recommendations for better blades that won't break the bank? I'm still learning but blade strikes are not as frequent anymore.

If your just starting, no reason to get an expensive set of blades. The Align carbon will work just find and they've had a recent price drop. You should be able to find them on most of the vendor sites here in RR for a couple bucks more then the b400 woodies. I just looked and found B400 wood blades - about $13. Carbon Align blades $15-16

In regards to the Blade 400, my suggestion would be not to spend all your money fixing it up with aluminum parts. Especially if it is your first CP heli. Just learn your orientations, and spend the money you have on replacement parts when you crash. Dont fix it unless its broken.

Yeah, here are some pics of my modified Blade 400 with all aluminum. The aluminum is nice, but if I could do it all over again, I wouldnt have wasted the money. Would have bought better servos/gyro.

I've wasted alot of money on upgrades.
I finaly realized that if it don't fly well or last long with out the upgrades, trash it and move on to something better.

Thanks for the lessons E-lite and Align

PS im not saying the blade 400 is garbage just trying to say save your money for better stuff for after blade days are done and you learned how to fly.
