View Full Version : Lightning 4 Blade Head

I just received my 4 blade lightning head from RC-Experts so I thought I'd share my first impressions.

First off, I ordered the head ($99) and a Trex450 S Aluminum kit ($169.) the week of Christmas, they shipped the following day and it arrived today. Not bad considering there are a lot of holidays in between... it came from Hong Kong.

Now the head. First impressions... it a good quality head. Build well, although it is not CNC as stated. The parts are actually molded from CNC originals. I couldn't see a seam at first, but it is visible under the right lighting conditions. Still, as I mentioned, it's not really an issue since they are well finished (by hand?). My only concern is that I hope they used quality aluminum when pouring. However I'm not worried about the process, I used to race motorcycles in the 80's and a lot of stress bearing parts (triple clamps and head) are molded from alum using the same basic process.

Making the parts from a mold then finishing by hand is the only way they can keep the pricing down.

I did some measuring and it looks like a few things can be swamped out such as the main shaft for the titanium version by align (at a later time). The button top on the head appears to be machined as does the swash plate. Although if this project works, I may swap in an align swash plate after drilling an extra hole for the fifth ball joint.

The thing I like about this head is it's REALLY simple. As long as the grips don't break, I can probably make my own replacement parts on a lathe. Later down the road I think I'll see if Align feather shafts will fit. I didn't see any place to buy replacement parts... at $99 I can't see the point.

A word about the Trex450 S kit I bought, I got the cheapest I could find. I didn't want to gut my Trex 450se v2 for this experiment. I like alum so I didn't care that that was what I found.

BUT when I opened up the package I saw that they had swapped out the alum frame for a Silver Carbon Fiber frame... ok... it's not what I ordered. But that's ok... I'm doing a carbon fiber/ silver alum theme on this baby.

BTW... the only weakness I can see are the control rods, they are thinner than the stock align control rods and seem to be made of a weaker steel. I plan on getting some alum rod and using my lathe to made a set of rods that are more robust.

All in all, if you want to get into Multi-Blade. I think this is your best bet. At $99 you can take the money I saved and buy two more gyros.

I'll keep everyone posted on how it goes.

ddragon,

Any update on how your heli flies? I'm really interested as I was looking at the same head. My main question is how difficult is it to set up and how unstable is it? Any input would be appreciated, thanks!!

where you able to remove all of the balls on the swash plate. B/c I purchased one and in taking the balls out of the swash plate i broke the one on the right side of the swash plate so i purchased another swash plate and in trying to change the ball again i broke the same one. I am not sure weather it is me or if it a problem with that side of the swash plate.


P.S. The reason i was changing the balls i have a blade 400 and the balls are smaller
