The Assault 450L assembly kit follows on from the already popular range of Assault 450 helicopters. It features a range of improved and upgraded parts whilst retaining the functionalilty and quality that you have come to expect from this superb range of helicopters. Even more of those fantastic CNC machined aluminum parts with many of them anodised an eye catching green.
Some of these improved features are as follows:
• Helical pinion and main drive gear for reduced slop and wear
• Longer tail boom (385mm), this is 40mm longer than the earlier versions
• Larger main rotor diameter (will accept up to 360mm rotor blades)
• Larger tailrotor diameter (67mm tail blades)
• Re-designed and improved carbon side frames
• Tail is torque tube driven for improved tail response
• More parts are CNC machined from aluminum and less are molded nylon
• Improved rotor head and swashplate system
• Fully CNC machined tailrotor gearbox with nylon bevel gears
• CNC machined aluminum motor mount
• Quick release sliding battery tray
The list goes on and are too numerous to mention here but there is one more that is a little different, the 450L has a CNC machined tail servo mount fitted between the main frames under the tailboom. This stiffens the frame at this point and also gives a nice straight linkage to the tail. It has also been made large enough to carry the slightly larger and stronger tail servos that are on the market today.

Bought and build this Heli last week and overall a good Heli but has a few flaws.
One of its flaws is the quality of the aluminum. In my case it was in the swashplate and the anti rotation bracket.
In both cases the threads in the aluminum where completely gone after putting in the screws 2 times. In the case of the swashplate if i hadn't seen it a crash during the maiden was a sure thing.
But other than that it's a good Heli. Flying it with Rotorstar main blades and they don't disappoint me. Together with the turnigy s306g-hv servo's on swash and tail make it a well balanced setup. Only "brand" stuff I got on it are align esc ,motor and a beastX plus.
But a good Heli for a fair price only thing is getting used to the new battery tray system.Dont waste your $ on any other 450 kit. I did and just found this 450L is way way superior kit. Why? Canopy is FG. Frame is assembled and even the frame sharp edges are smooth. Shipping was 4 days and low cost. So 6s or 3s build is up to you. What a nice kit @ 1/3 the cost.Couldn't wish for better. It's fantastic value and quality.Have assembled it and have to say it is much better than older 450 PRO helis. Great improvement from GARTT production... The only "problem" that isn't realy a problem but a must do is mesh well all TT umbrella gaers with apropriate shims to make them fit well, but not too tight eather - like all gears in general... All the rest was OK, use threadloch everywhere and grease on thrust bearings main head grips and tail grips as well. Wil tell more after first few flights... ByeFinally got this bird up in the air and after building it and flying I can say the quality is great. Everything fit together nicely. I always pull all the screws out of the preassembled parts and they were mostly thread locked so I probably would have been ok not doing this. flying was perfect, I didn't have to adjust anything after the 1st flight, everything was just spot on after setup on the bench. I used the ZYX - S2 and it held solid. This is a quite a difference from the HK kits on this site as I had to buy a lot of Align parts for the tail and a new swash as its quality was quite poor (RIP).il miglior elicottero classe 450 lavorazione perfetta piccolo neo viti un po deboli e alcune con testa torxgood I like it was abit battered by the post but all parts were okI just got my package today. Took it out of the box and I can tell you right now, very high quality! It is by far, one of the best craftsmanship work I have seen on a heli. Fantastic job HK!!!!! My favorite place to order everything I need for my heli's. Do yourself a favor, get one, you will not regret it!seemingly nice product, which was quite fun to assemble. most parts were already put together, but take these apart, and check for proper lubrication and loctite.
the overall quality is ok, but there are a few bad parts:
- the ball links are finished quite poorly and look a bit soft. also the ball links on the tail control rod tend to bind.
- the main gear is made of low quality plastic, it started showing wear on the first spool (even though i checked the motor gear mesh three times)
- also, most gears look cheap, especially the umbrella gears for the TT drive
- the dfc arms tend to bind to the blade grips
- the canopy is a bit of a slapdash job, a little misshapen with painting blemishes (but nice enough for the money)
- one of the TT bearings wobbles when rotated
i suggest replacing all gears asap, and double (triple) check everyting for binding and unwanted shifting. my maiden finished with a bad crash caused by a TT umbrella gear shifting, getting chewed up, and me losing tail control totally. (2 servos broken, tail boom bent, blades broken, main shaft bent, featherin shaft bent, etc)
Just received the Assault 450L For the price this kit is amazing. Excellent QC very impressed with this kit. Front and rear tail gears mesh really well very smooth rotation no rough spots. Tail is sweet thrust bearing in tail holder. The cf frame on mine is flawless. Even the cnc parts are great very little machine marks. Head and swash plate also of good quality.Fiber glass canopy has very nice finish. I'm telling you this kit is great. The only thing that you might consider replacing would be the main gear. That is all I will replace..
