Luca,

actually nobody knows anything about the quality of the SRIMOK.
But one can suppose the quality to be the same as their tuning parts and heads. Therefore, everything should be fine.
Furthermore, the pics released show nicely and with passion styled parts and details.

MA`s new 90 seems to be designed more for pure functional reasons. Very much straight forward. Or in other words: The blinky sex appeal of each part was not taken into account that much.
A great machine anyway I guess with MA´s proofed quality. But, as you know too, with unclear release date.

Both machines are new to market. Both with the "latest and greatest factor".
Sometimes it is a good idea to wait for first issues and their solutions. I know that decision could be a difficult one for any heli junkie.

Lastly, it primarily is a matter of taste.
Then of parts availability.

Thanks. Just did a google search on it as well. It is a nice touch that Srimok 90 gets this nice touch. I thought might be nice to list them here in RR.

7075 is an aluminium alloy, with zinc as the alloying element. It is strong, with good fatigue strength and average machinability, but is not weldable and has less resistance to corrosion than many other alloys. Its relatively high cost limits its use to applications where cheaper alloys are not suitable. 7075 has a specific gravity of 2.73.

I like this "The first 7075 was developed by Japanese company Sumitomo Metal in 1936.[1] 7075 was used for the Zero fighter's air frame of the Imperial Japanese Navy in pre-war times."

7075 is widely used for construction of aircraft structures, such as wings and fuselages. [3] Its strength and light weight are also desirable in other fields. Rock climbing equipment, bicycle components, and hang gliders are commonly made from 7075 aluminium alloy. The bicycle industry is also using 7005 and 6061 aluminium alloys. Hobby grade R/C's commonly use 7075-T6 and 6061 for chassis plates. One interesting use for 7075 is in the manufacture of M16 rifles for the American military. It is also commonly used in shafts for lacrosse sticks.

Due to its strength, low density, thermal properties and its polishability 7075 is widely used in mould tool manufacture.

By the way guys, when I posted this in local forum. I got this comments below:

hmm, something about 7075 aircraft aluminium. Most of the CNC parts for Rc helicopters uses either 7075 and 6061 alu. These 2 are the preferred grades because of their strength and light weight. Another important reason is because the finishing is very good. This means that when the block metal is milled down by the CNC machine, the surface finishing and the tolerance is pretty good.

However, despite the strength, both metals will not withstand hard crashes. 7075 tends to be lighter, but softer. 6061 is heavier, but stronger. An example of 7075 is parts from http://www.microheli.com. If you read past threads from RR, microheli parts bends easily in crashes.

But anyway, do post tons of pictures when you get the heli. It is really a beauty. Unique design, super high quality (as seen from pics). Looks very good.

I would presume there are many different grades..I am quite confident that KSM uses the best if not a good grade of 7075. Anyone want to comment?

Microheli parts from 7075? No way, we were importing those, and we tested the material.
plenty of companies claim they do parts from 7075, not the case.

some facts..
1- 7075 is NOT available every where in the world, its mostly come from Europe, so if Microheli manufacturing in Vietnam, they have to import 7075 from Europe, which is NOT the case.

2- 7075 is very hard to work with,machines and tools working as tripple as hard and also normal tools will break when CNC 7075.
its much harder then 6061 which today's most helis are made from, and lower quality "manufacturers" producing alloy mix with 6061, so its not even 6061.

Kasama do respect the rules, if they claim its 7075, then they import it, and therefore the cost is relatively,

i have to admit that the kasama head on my 600 is really made of high quality metal, but i have never had a MA, so i don't know how is theyre quality and machining.

thank you

Futurac..Thanks for your clarification..!! At least it brings some justification to MicroHeli stuffs..

I am very confident that KSM is of good quality, seeing so many comments.
