HJK Speedwing LP1 Build


Hey,

Since my Stiletto didn't like life any more I needed a new s400 pylon machine.


A (incredibly well wrapped and protected box) arrived today with a shiny carbon machine inside.


Pictures below, alot are compared it size wise to my stiletto.


Its a beautiful plane, you can tell its been made by people that care. It's got the same kind of finish and attention as Yuri's xplane if you are lucky enough to have held one of those.

Wing is thin, i measure 11mm at the thickest point and it quickly gets smaller. Very stiff. Nothing on it bends or compresses when pushed. The main spar looks like a end grain balsa with carbon top and bottom. Ill take pictures when I open it up for servos.


Going to power it with 3 and 4s 2200's with a HET 2w + gm 4.75x4.75 folder to start with. Once that dies I will get a mega to carry on.

I can easily fit the 5s neu energy 2100 packs! The body is MASSIVE for the size of the plane. This plane could pack some scary power!


I'll update as I go

Want.

It seems to be lacking something... I dunno... Maybe it needs more carbon

I'm salivating uncontrollably!

It's fantastic to see that someone finally got one of these beauties from HJK. I think this will inspire others to do the same. I found their website last spring and was in awe. I'll bet countless others have come across their site and said wooooooooooowwwww, but just didn't plunk down cash yet, waiting to see who would buy first and report back. Thanks for being the first on RCGroups to post about this highly desirable model from the new German builder HJK.

What a plane! This could be the holy grail of pylon racers. Time will tell. I'm sure I'm not alone when I say that I'm very eager to hear your flight report and general commentary after you've worked with it after a few flights. I already know it flies well because I've seen the vid on Youtube. Obviously, it's not going to be a dud. But the guys in the video don't offer any comments on the flight. You however, might be more inclined to do so. Hopefully

Cheers!

What is the wing bolt setup? Does it come already drilled out, wing and fuse? And what about the motor mount? Do they include one? I know it's not already installed, according to your fuse interior picture. Is there any hardware provided with the model (pushrod, screws, horns)? They don't mention anything on their website.

thanks!

No hardware, no motor mount, no wing attachment bolt

It's not a ARF for sure.

Im going to copy Jacko's stiletto hold down for the wing. Basically a alloy plate under the lip in the fuse, and a washer/bolt through the back. It is not drilled at all. The front of the wing hold down is a solid "lip" of carbon. Much better than the pin of the stiletto.

I hope to have that part done shortly before I start on the tail so I will take pics as I go.

For the tail I will do the setup on wasps/mini hawks I think. Small bolts up through the body, through the tail into the fin to hold it all in position, and epoxy on the joins.

That weighs more than the entire plane! (it looks good/scary sitting in it though.....)

Test on HET, then I'll look at that... I guess I need to do something with it


I need to buy some scales and check the weights of things. I see in the past day they have changed their website to say their LP1 has gone on a diet down to 200grams, wonder if mine is one of those or if its heavier. Tail/fuse weigh stuff all, and the wing isnt very heavy

I still have my heart set on a Viper, but this one interests me too for sure.

Tell me sykotic, did you get this from HJK direct, or is there a distributor (are you in the States?)?

Did you pay US dollars? If so, how much did you pay?

I'll be watching the build!

Thanks!

Im in New Zealand, brought straight from HJK.

I paid their price on the website, minus VAT. I think it was 200 - 19% then 40 shipping (and the shipping was worth it imo, big box packed REALLY well). Total of about 200 euros.

Took about 10 days to get here.

tail is 23g
fin is 6g
fuse is 56g
wing is 182


267g

Very interesting that the new ones are now 200g according to their website!


For comparison the stiletto's wing is 185g with two ds09 servos in it.

I don't have the cash (or the airspace) for one of these critters, but I'll be watching this thread. We need a drooling smiley...

I've often wondered why more Speed 400 class racers don't have huge power-packing fuses like this one. Seems like if you want to go stupid-fast, that's the way to do it. Still, 5S sounds... downright psycho

What sort of speed range are you expecting for it? A 2W on four cells with a 4.75x4.75 has to be smoking, perhaps in more ways than one
