Yippee!
Launchmodel Luna E-V (HK Riot / Lunar / Makis)

Iíve been lurking around for some time as I have a hotliner itch to scratch. What I want is just a sport flyer capable of good vertical performance, and a turn of speed with the motor off. Of course, for a ďtoe in the waterĒ type of experiment with a model of this type, price is a key factor. For a while Iíve been tempted by the Launchmodel planes as they appear to be good quality, and are the source of models for some of the specialist dealers. I sent them a few queries on pricing for a few models and each model was still very expensive even to get multiples to my doorstep in Australia. On the Launchmodel thread, I learned that Hobbyking were about to begin distributing these, so I waited, and sure enough:

http://www.hobbyking.com/hobbyking/s...dproduct=18456
http://www.hobbyking.com/hobbyking/s...dproduct=18453

So Iíve now got a Luna E-V on the way. I know that this model is related to the old version of the Makis, and maybe an aircraft called the Falcon F3B-E, but I can find scarce information on here about any of those models!

Specs:
Wing Span: 2000mm
Length: 1180mm
Airfoil: MH32
Wing Area: 43.8dm^2

Iíll be happy to post pics when it arrives, and maybe have this thread as a bit of a build log. Due to the fact that I canít really find much information, Iíd love to hear from some of you experienced hotliner pilots on what would be a suitable hardware combination bearing in mind a desire for only moderate performance (Subsonic style). Iím not looking to set the air on fire; I just want a taste of what a performance model might be like.

Yeah I saw that model as well. It looks so much like a V-tailed version of the falcon I bought from Icare.

The pictures on the icare website doesn't look that similar but check out:

Please keep us posted. If it does turn out to fly anything like my falcon then you are going to really like your new Luna. Very well built plane and is probably my favorite glider/hotliner to fly. Actually I have always preferred V-tails...hmmm maybe I'll get another
Cheers Mike

The stock comes in and out. This is a JIT (Just In Time) item that is built direct from the manufacturer only when a customer orders it, aka they probably release stock according to the manufacturer's ability to assemble kits on some X/week schedule. I bought it the day after it came out when 5 more were added to inventory. I would just check every morning for new stock.

I know, the international warehouse says -7, we got 5 here in oz and you just don't know when stock will come, hopefully soon for all. Hope to hear more from people with them, setups issues etc. good luck Krasimir

Thanks

HK Info say: Stock usually arrives every 10-25 days.
But nobody can say since when they count these 25 days
I hope before the end of the summer

So subsonic, how is your riot going, any pics yet? Have you settled on a power set up? Servo choice? Any issues to speak of?

Hi Brendan,

As is usual (and boring) mine is on the shelf behind another project. That doesnít mean I havenít been thinking about it though!

I have taken the model out and gave it a good once over. Everything checks out great. It arrived with no damage, and goes together well. It looks to be a very well built model. The only difficulty I had so far was that the carbon wing bar is a very tight fit in one wing, and I wasnít able to get it to go in all the way without really forcing it. Then, thinking on trying to get them apart again I decided to stop forcing it there and do some slight rework. Iíll have to think of a way to gently ream the ID of the wing tube so it fits nicely.

From the research Iíve done, I couldnít find anything on a ďhotlinerĒ version of this aircraft. Iíve found quite a bit on the slope version though, and all agree that it is a great model, and strong despite the ďlackĒ of carbon. Those reviews have given me something to go on for servos, as more than one are using the Hitec HS85MG for all surfaces. I donít particularly like Hitec servos, as Iíve had way too many failures, so in thinking of a similar size / power I am considering these Ino Lab serovs

They are pretty close to the size of the Hitecs, have a bit more torque, and are digital.

Whatís doing my head in though is the power system. I was actually waiting to see what others are using first in order to get an idea of what I really want! This is my first hotliner, and I am not going to be flying this at a club much (mostly a local park), so was thinking of a pretty tame power system. Maybe a 4S 2500 and low KV outrunner, 14Ē prop or so? That sort of setup would be around 800 to 1000W, so no crazy performance, but good enough, safeish for a park and cheap?

Thoughts?

Subsonic.

Wow thanks for the reply SS. Mine arrived today, with no damage. Sigh of relief.
Weighed the kit at 980g approx. Some 200 grams heavier than VladImir's mini graphite, but very similar in all other respects, yet not as strong no doubt. Thoughts? I have alot, but some of the better ones may not be realized due to costings. How much do you spend? Hotliner? Not sure that description applies to me. Um we shall see.

Not sure that description applies to me, because I haven't bought the mini graphite, I have bought the hk riot. Um we shall see. What's your other project? I have a half finished gee bee and a hk stinger on the way. So this one will take a while for me too.
So you think this plane is similar to the mini graphite? I haven't seen that plane. Got a link?

I have some info on my other project in my blog. It's a scale FPV supercub. Pilot's eye view, that kind of thing. Not exactly high performance!

Ok I always have trouble with links, hope this works. This one is at hyperflight in UK. Not sure where you might pick one up in aust but I would probably start with hyperion cos they are just up the road from me.
Anyway comparing the general stats they are similar in shape n size but I am sure a m-g owner might not like the comparison being made. The m-g is some 200g lighter to start, same airfoil though, length almost the same 1.9- 2 m span, 2 piece wing, but the build quaility and strength difference between the two, I am sure would favour the m-g, oh and the price tag? $$$
There is a link to rc group thread and a build log too on the hyperflight page good for a look.
Not overly impressed with the visable seams on the riot and my wing brace is tight one side too. Going to have closer inspection today, hardware etc. start with motor mount for 36mm out runner, tight squeeze and spinner to suit, 38mm.
Inrunner might be better, or hyperion 30 size gs glider outrunner, $120 though.
Might have been easier to have the m-g, would just settle for the best set up possible, forget the cost.

That’s a great link, thanks Brendan. Useful info as the specs look very similar, so the hardware should translate well.

I wouldn’t be regretting the Riot for the m-g. That plane is twice the money by the time it’s in your hands. The Riot, built as a cut price hotliner, shouldn’t disappoint.

It's the little things...

Well bit of a first dry fit happening at the moment, front cap screws for wing mount will not seat completely into the rebate allowed for them and the front join of the two wing halves does not quite meet with the seam in the fuslage as you might expect, although measuring wing tip to tail tip seems close within a mm or two. Do not have the wing brace in yet as it is tight, have tried a little light wet n dry 360 grit but not quite there yet. Cup of tea time....
