If you try it again put a tail shaft in the slide shaft while you are loosening or tightening it. That will keep it from completely crushing the wrench flat end. If the slide shaft is tight on the tail shaft after that, roll a small piece of 320 or 400 silicon carbide sand paper into a slightly tapered cylinder where the small end will just fit into the wrench flat end of the slide shaft. twist the sand paper in the bore removing a small amount of material untill you get it to slide freely again.

This is great work! I have spent my time in machine shops and appreciate what you have done here! I am running a Sonix B400 tail on my frankenhili and have 5 differant combinations of CF blades that I can run, so the question is which one of your chinese weights will work for me. And being the bargain hunter that I am is there any discount for a couple of sets. LOL. If this works I will link this into the Eflite section and post you up there as most of the guys are running aftermarket tail assemblies that I am talking to. Thanks Bro!

If the tail blade bolt is 2mm my Trex450 SEV2 weights will probably work. I will PM you the purchase info.

I will meaure it when I get home. Now that I think about it I am pretty positive it is a 2mm bolt since I just machined out my ultralight 450 size titanium skids out of china for a CX3 build that I am working on with a 2mm tap and I can see the bolts in my mind because I just pulled them out yesterday replacing the rear CF blades with another pair. The pitch was a .4 if I remember correctly.

I was wondering what the difference in required force is between the stock pro tail and one with your chinese weights added as well?

On the video there was an order of magnitude reduction in the force required to move the slider, I assume the difference is less dramatic on a tail with integrated weights?

This is a video I did on the T250 on the Weighted grips versus the stock grips with my weights. Same thing would apply to the 450

Awesome, thanks for that, a very clear demonstration that the align pro grips are not doing that much! I think i'll be investing in some of your weights, i've just shelled out on a fast but low torque tail servo for my 450...

What I have heard is that the stock tail blade grips with my original weights performed better than the new weighted grips by themselves. So as a service to my fellow HF members I designed a weight for the pro/sport tail that gives the same tuning as the original setup. If the weighted grips were so good why do they still need a chinese weight that is about 90% the weight of the original?

As for price I machine most of these on a manual machine in small batches(20-60 sets). Not a screw machine in china. Yes these could be a lot cheaper if I had 10000 run on a screw machine. But since I only sell few hundred a year that wouldnt be a great idea.
Most guys are greatfull that I bother to make them at all.

Just ordered a set for all 3 of my helis, Yesterday. Now just waiting to get them and then give them a try. I knew I had seen somewhere on a thread that someone made them. As far as the price is concerned I think they are a bargain for a quality product,Made in the good old USA. Unless you own a metal lathe and have the skill to use it, Which most people don't have either, and don't want to stick a bunch of washers and then guess if you are right or not, More then likely NOT. Then a few bucks compared to the total cost of the heli is not much. And they are highly recommended from all of my friends. Thanks for helping us out Heim Joint

Add me to the list of highly satisfied customers bro! And when I get my 600 setup I am ordering more. If I were any happier I would buy a set and tongue pierce myself! LOL

Dose this work better than the previous 450 mod that uses the steal ball links for the weights? I can see that it involves less work with your mod but are the results better or the same? If the results are better I might have to get a set for my SE V2.
