hk assault 700 unboxing
soo
i was expecting my package to come next week , but as luck would have it, i got it today ( i was mislead on tracking) so i opend my assault 700 box and inspected it, so far heres what i can see, -- the frame altho thin,, is real cf ,, -- the main gear is a bit on the iffy side,, ( i feel if you dont upgrade main gear or get or make an adjust motor mount so meshperfect, than chiping of teeth may occur ,, so this i feel critical for longest gear life,,) --canopy,, is right on par with my tsa,, and miles ahead of my blade 550\600x 's canopys. --head-- seems like a winner, very nicely done,, very soild.. --tail--- again very nice and solid feeling,, and on a side note,, SMOOTH --bearings -- all seem ok to be honest,, this was one area i was afraid id have to change out from the get go , but dont seem that way.. --battery tray--again real cf , and alum ,, seeems good --tail boom-- seems no diffrent than my blade booms,, but not as quite as beefy as my tsa --swash-- i also have the updated ver of the swash,, and i will be using it now what could be improved so far just on unboxing and molesting it? the way its boxed,,,, its kinda like an all in one shipping /product box in one , so i guess more prone to mail damage,, mine was just fine tho,, the frames could be a little thicker , but im sure it will do just fine,,, i will tear the head down in the days to come and regrease and loc tight everything, and following will be build videos ,, so far i feel this is money well spent, i really feel take the main gear aside , that this heli is quite the bang for the buck , i plan on beating the piss out of this bird stock (minus modded motor mount) and see just what it is up too , and will be videoing and posting my findings on my own personal exp.. i feel as said before . the only thing i may have to change out is the main gear, but im ok with that,, im just really intrested to see how well this bird really flys, i wanna see cost of replacement parts as they fail , than i will replace with aglin as needed, so , as of now the bird cost me the price of the kit,,,, so we are in $215 ,,, electrics and motor will not count as they have nothing to do with the assault as per build and fly grading,,,,but none the less i plan on having a hw 160amp esc , some turngy servos , and aglin motor, so as of now , this is another "380" type clone that is good,, card is subject to change ,, as we will see how this unfolds ,, but as of now , seeing it , molesting it, comparing apples to apples right next to the tsa and blades, i feel this is underated big time,, and im here to disclose the truth , weather it turns out to be a hidden gem... or a money pit better worth using for firing practice ,, together we will see,,, enjoy

Curious about your servo to swash links... I have read elsewhere that they are a bit too long. The one that I have has the same issue. It is impossible to get 0deg pitch with the servos arms at 90deg.
I have measured mine. The appear to be about 4-5mm too long (compared to Align). Otherwise, I agree with your assessment so far. Looking forward to seeing some video of you beating it!

Does it come with turnbuckles? If not these are inexpensive:

Yes it does,, . I heard some are too long and require aglin... If mine turn out to be to long ,I'll just get out the demel and take off 4 threads each end , that should work it out

-------------update----------
ok , so lastnight i had the chance to loc tight the frame and put together the battery tray, heres the outcome so far,, i managed to strip out 2 of the 4 screw heads of the swash plate retainer,,, it was tight , real tight when screwing in,, no biggie , had this happen on other kits,, i use good drivers so i dont belive it was a bad tool that caused it ,, i have 2 other screws laying around to replace them , so again , no biggie, but must be noted ,, the screws themselves seem just fine grade wise,,, both screws that stripped had weird heads to begin with (maybe bad die hit on screwhead?) , so im sure that happend to aid in the failing of the screw head,, other than that , the frame screws had loc tight already form factory on about %75 of the screws,,, the others either didnt have any loc tight on them , or the amount was too little to get that "click" when you break the loc tight seal in the threads,,,, ******************************* now on to the battery tray ,, i love this thing, great style , it just all around works,, the cf thickness is thick,, it wont wear out any time soon,, the sliding action of the tray is smooth and stirdy ************* landing gear, the landing gear seems like if i land hard , it might break,,, but the same could be said about cf gear as well.. i will not be changing this none the less , for i can land just fine ********* i also dissassembled and re assembled the tail ,, again , its smooth , sturdy , and just works,,, the metal seem just fine and up to par,, *********** i will be finishing the tail and doing the head later this week , or weekend ,, just wanted to give you guys an update

Hello dnj1985,
I´m on the same boat as you , I´ve bought an Assault 700 a few days ago and seeing your progress I think I´m a bit ahead of you I just wanted to share some of my findings with you and hope you could verify if you had the same issues as me, so here it goes: First the swashplate, mine came almost OK... one of the holes for the swash to servo ball link was badly machined so only a few threads where good and for this a new swash is on its way. Second the gears, all of them look well made, but the material used is too soft and the tt is very dificult to insert in the front and back umbrella gears, they also seem to be a little wobbly, and because of that a whole set of align black gears are also on its way (but that´s like the rule for clone helicopters anyway ) Third the screws for the frame, too soft, just tightening them made the heads fall off , also a set of screws are coming Don´t get me wrong I love this kit, the battery tray, all the aluminum parts, the head, the frames, tail case everything else are very well made and is a perfect fit for the Align Speed Fuselage but is not a beginner kit you´ll need some experience in building kits to spot the faulty parts, which with this kit are few and simple to fix Anyhow i´ll keep an eye to this thread for more updates from you, cheers!!! |

my swash is perfect.. sorry you got a faulty one,,
as for the tt gears , i must disagree .. they are fine imo,, the main gear is the worrie spot for me (seems to hard ,, easy to crack) , but none the less , im gonna use it for the sake of this thread,, the owb is another thing ive heard was an issue , but again , for the sake of this thread and only replacing after part fails,,,(btw trex had same issue ,,kde stepped in and saved day) now on to the screws,, again i must disagree , yea sure i rounded two screw heads , but like i said , from the start they looked , oblong , , 2 out of what 45 some screws? , ill take that for a $200 price tag,, but snapping the heads off as you say you are doing , well im sorry my friend , but stop using an impact gun on your helis i had no problems as far as the grade of the screws ,,, just said head stamp not deep enough in 2 screws.. im intrested to see and compare our findings, do you have any pics? maybe you can show us what you ment by your tt gears?

btw , what umbrella gears did you have to assemble?
i thought all came preinstalled? because im sure if you pressed out the gears, you didnt have the proper tool , and now the bearings will go soon and will stripp the tt gears due to the bearing failing and cause a slight "rocking" in the gear mesh ,, and thus giving a false review on the bearings , saying there crap cause they went bad after 20 some flights,, and the tt gears as well saying the stripped easy hmm i wonder what willy wonka would say right about now?

Hi guys
Following this thread also I have had my kit for a month or more now and I have found I have had 2 or more of the frame screws strip and 1 snap off I am still waiting for a new screw set from Amain ( getting parts to auz sucks ) I have also found my tail setup was still not free enough for my liking, so picked up a secoundhand one from a local ( really notice the difference) No majors but shitty when parts take so long to get When I get the new screws will continue with the build Cheers watho Edit, sorry looking forward to all of you inputting into this thread And particularly the electronics as jumping from a 550 there is a big difference Go for it guys Watho

Well, I was using the impact gun on the softest setting, but maybe it was still too strong for this application
Seriously tho... at first I thought I used a little to much force but I was careful on the following screws and still managed to break a few more , I had some screws left from another build and those went in just fine so maybe the ones on my kit where from a bad batch... oh well nothing than a $10 worth of screws couldn't fix , oh and for the record only the M2 screws where faulty, the ones used on the electronics plates etc... the M2.5 stepped screws used on the main bearing plates and motor plates where OK. And on the gears matter... actually what I meant was that the end of tt shaft has to enter the "cross" hole on the gears (you know.. English is not my native language so bear with me on this ), those "holes" where made to tight (at least on my kit) so the slotted end of the tt was very hard to insert, what I did was file down the internal walls on the gears a bit and now the shaft enters smoothly, but then again I was planning to replace them anyway so maybe I was expecting the smallest detail to proceed Hope I made sense with the above. My build is on hold too, expecting parts to arrive in a couple of days, so I'll post more findings as soon as I resume Sorry for not posting any pics now, I'm at work and don't have any with me, but I'll leave one I took just for presentation purposes Looking forward to your progress guys!!! |

first off alagam,,, great body on that heli
i just may have to copy that idea,, i need the electrics for my build yet, im ordering them for xmas for myself... plus its winter her in PA , in the usa, and that means i cant fly for about a month and a half , only cuz im a puss in the cold ,so i dont fly below 50deg f but i plan on having everything done and flying by mid feb,, providing it isnt 30deg f outside,, so plan on the first true installment of the build with electrics and all , to begin first week of jan,,, and about the M2 screws ,,, i have to agree ,, thats the one that stripped the head on mine,, i guess this weekend ill install the boom and head and tail , that should give you guys a quick read for a moment to curb you addiction

ok so ive had a moment to get together the boom and other parts,, sooo here we go again,,
the boom-- the boom had the tt bearings glued into place inside of my boom , not on the tt,, ive givein the bearings in the boom a good knock to try and move them but they seem glued into place,,, so i guess thats good.. the boom itself again is made ok , and is true , as is the tt ,, -boom struts,,,, the boom struts when wiggled hard with an alen wrench in it did break the eyelets loose,, no biggie , a few drops of ca and i know they arent going anywhere tail pushrod- tail rod is cf , and is true as well , no warping that i can tell , one thing to note , its there is a setscrew to "pin " the boom inplace , where the boom is inserted into the frame,, so i recomend to drill out the hole so the setscrew grabs,, ( will show pics later) the ,mainshaft seems true ,, and no diffrent than my tsa or blade shafts,, same goes with the spindle,, the head,,, the head , did come with a very small amount of grease in the thrust bearings , and locktighted as well , i will put back together with red bearing grease ,, well there you have it , so far , no real hicups, in the build, i did take apart my owb and glued it into the sleeve so not to have mine jump inside itself,, next weekend i will grease the tail and assemble the tail to the frame , as well as install the head , (maybe still wanna hold out on servos) and install the boom , , my thoughts so far? so far my opinion is that this heli is an underdog, i mean , ive really had time to sit down with it , and finger f*ck it, it really seems like it will hold up just fine , the metal seems that up to par with blades , and the plastic is just fine so it seems,,, but of course all of this looks good on paper and the real test is when shes in the air,, , i may , for the sake of getting this going ,, i may just barrow my tsa electrics and put them in the assault so i can fly her before febuary

ok sorry it took awhile guys to get back here , but life was getting in the way
anywho onward we go,,, the tail came with locktight in the threads,, there was some grease on the thrust bearings,, but i cleaned them and re-packed them with bearing grease , the fit was good , no problems to report,, the tail went together without a hitch,, and after all was said and done, the tail was smooth as butter.. the tail gearbox was again just fine , the tt gears seem fine, and mesh good, they dont seem to have no wobble in them whatsoever , so good in my book, the carbon fiber again , is true cf , very nice,, altho as said before id rather 2mm , not 1.5 one thing to note: when installing tail gearbox on boom , remmember to use the metal "button" and line up the hole in the boom,, this "pins" the tailbox in place

ok now on to the boom ,
note there is a set screw in the frame ment to "pin" the boom to the frame.. i took a drill bit and drilled a hole in the boom so that the set screw has more to grab ,, i also inserted the tt into the frame first , and than inserted the boom over the tt. if your tailgear mesh feels rough or notchy no biggie, just locate the unbrella tt gear in the frame and give it a push twards the rear of the heli, you will hear a click , thats you reseting the umbrella gear into the bearing, it happend prolly when inserting thett into the umbrella gears into the frame,, the tail fin again is true cf , all was well in that aspect so nothing to report there so as of now , nothing to report, the boom struts were reglued by me and i also plan on drilling a screw / nut hole in them as well for added insurance,,

Hey dnj1985, I talked to gartt a while ago about the set screw to lock the boom to the boom block. They told me they would change it to a screw like align. I used an M4x8mm like align. I am surprised you couldnt report anything bad with the tail. I could not tighten the small screws on the tail because it would bind.
