Hi Kin,

Any news about the 810mm Huey blades?

I received a set of 360mm scale blades from Kin to test out...so here's some initial testing

The test subject is a grossly overweight 450 AH64 from Wing Wing with lots of custom mods...tipping the scales at about 4.1lb. flying weight. I previously had some standard '360mm' CF blades on the heli.

To start, these scale blades are a true 360mm hole-tip size. When you are trying for the biggest possible rotor disk, they really come though. Out of the package, the set of 5 came with weights of 41.48 41.54 41.55 41.55 and 41.57 grams. No balancing needed here .

At scale type speeds (1900 headspeed on my model), the extra weight of the blades are well in the safe range...about 75 lb of force with the scale blades vs. the 50 lb of force with my previous 29.3 gr CF blades. Considering that pod/boom helis running this size CF blade around a typical 2700 rpm have the force at over 100 lbs...should be just fine.

So I did a back to back comparison of lifting power and general forward flight using the old and new blades. One thing that immediately stood out was the very noticable increase of max pitch lift. With 13* of max pitch on my model, I noticed a very welcome pop. Before the lift was rather soft and weakish...these new blades have some good bite and made the heli rather 'peppy' whacking full collective. A very welcome effect on this flying brick.

General forward flight indoors and windless showed no wierdness, and I think the asymetrical airfoil provided for less actual pitch (my calibrated thumb felt a bit lower on the stick range, lol).

I ran my eagletree to get some amp draw readings to make sure these blades didnt start sucking down the juice like some of my 'scale blade' experiences. Let's just say these are pretty good...no difference of any significance in standard flight. On full collective they provide much more lift...with a increase of amp draw as well. One can expect that. I should note that I am running an undersized 22x15mm motor on this heli, and the motor is stalling at max pitch conditions so that is why there is such a headspeed drop in the log charts. This particular motor really sucked on a MiniProtos in pod/boom form due to the lower numerical gearing of that heli...you can imagine how well it is doing with a porky 4 bladed scaler . I do plan on getting a real 22x21 motor for it soon, and ditching the CC governor for a Vbar/Hobbywing setup in the future. Should help out in the maintaining headspeed department.

Anyway, getting back to the review...I plan on seeing how flight manners are outside in wind and will post about that when the time comes. I am also thinking I might be able to knock back the headspeed a little bit also for better efficiency as the asymetrical airfoil seems to work on these scale blades .

So far...I like 'em!

More later...in the meantime some pics and chart:

Not much wind today, but it made it outside. I gotta say, I like these blades, so I'm keeping them on the heli.

The only downside of these blades is that they renewed my interest in this heli and made me order up a new power setup I've been thinking of for a while

Well, here's some flying around with the blades...

Sideways, somehow I lost the overall view about the smartmodel blades range.
Are these still plastic or composite blades?

Thanx, Rinaldo

The 360's are plastic...but I believe that anything bigger than that is CF? Kin?

Are these the blades you tried out?
SM 4536-4 Scale rotor blades 450-480 360mm

I had bought a set from Kim last year of scale blades but they where much shorter than the add said. I tried to contact Kim and Smart Models with no reply from either.

thanks for a reply

Jim

I dont know, I think so. These blades are asymetrical, have an arrow molded on the top and are 360mm from the hole to the tip. SM in the past had some other 450 sized scale blades also, but those were shorter and I believe symetrical IIRC

Thanks for the reply.

I guess I will not order any, have one set of Scale Blades from them that are to short to work, even though they advertised them as being longer.

I just checked the website for the 650 mm blades. Is the weight a typo??

Well, I do have a .60 LongRanger with a stretched T550 inside of it. It does have 713's on it now...but scale-wise 650mm is more like the 1:1 version if you compare photos of the real thing to the model. So yes, I would be interested
