Never Mind...I just pulled out the plans that came with the Hots kit, and gave them a good looking over. By the time I got everything the way I'd want it to be, there wouldn't be much left of the kit! It would probably be easier just building a good plane from scratch, than it would be to convert the Hots.

...Oh well, it was just a thought...

Right now I'm leaning toward building the Komacro 15, or buying one of those electric Laser 3D's and converting it to glow.

I had an artf 3d mini laser and it flew ok - not 3d though. The control surfaces warped after only a short time. The covering also stuck together on the control surfaces (between the top and bottom of the aileron between the void of the wood). I took the gearbox off and fitted a cobalt 400. It was ballistic but struggled to take the stress. It Broke!
I think this model is a beautiful kit but would need to be thought out properly before fitting IC. The weight of the battery pack (500ar 8.4v) was also, in my view, a bit heavy.
My opinion of this model is it is best left as an electric.

The comacro looks like my Mini Jazz. Powered by an mds18 but 25 would be better. 33inch wingspan and very maneuverable.

Hey Neil...Thanks for the new option!

Do you have a link to Weston Market's web page & do you know if they are available anywhere in the USA? Although shipping across the pond would probably be more than the kit, for such a small airplane.

It seems like I'm always seeing good designs coming out of RCM & E. You don't happen to have the plans available, do you? Sure would be nice to have it in ACAD, or any format, for that matter.

Thanks for the Laser 3D advice, too...I think the Komacro 15 just got bumped up on my list to number one now! Unless, of course, I can get my hands on the Mini Jazz Plans?

A guy I Fly with regularly is friends with the owner of Creek. They are supposed to meet tomorrow (Sunday) and fly some new planes. The .15 size 3D is one of the planes they are flying tomorrow. As far as I know it is a prototype, the rest are still on the boat. If I have time I'll try to go see it fly and get the details.

Try this link to Nexus for the Mini Jazz plan.

I've heard that there maybe an ARTF coming back soon. It used to be distribited through www.westonuk.co.uk but they stoppped selling them about 2-3 years ago.

Also try this link for other plans by the same designer:

After reading this thread it got me thinking last night what to do with my mini laser 3d. So i decided to make a new fuz. I shall do the tail and covering tonight.Its suited to an OS15fp, should be lively.

Hi Neil,

Thanks for the Mini Jazz info!

What exactly happened to the original Laser 3D? Did the Fuse brake in half in the air?

Anyway, could you keep us informed on how the new improved Laser 3D flys with the OS 15FP in it?

Mark

Mark

I think the tail broke first, but it was in 3 when i picked it up. There was a clean break around where the fuz goes over the wing.

Neil

Something you guys might consider, is using a lighweight, bushed 25.

I have an FP 15 myself and think it's a great running little engine.
But if I recall correctly, it wieghs 6.0 oz with muffler, and my old (Taiwan made, not Chinese) Magnum GP 25's all wiegh 8.6 oz. with muffler. That's only a 1.6 oz wieght gain, but your getting at least a 20 oz. thrust increase.

There's also some simple, low or no cost mods you can do to this engine to gain at least 1000 RPM on a 10x4 prop. This results in at least a 28oz thrust increase over the 15.

I had one years ago on a 2 1/2 lb. foam Sure Flight .15 size Cub, and the thing would take off like a dragster in 5 ft. and shoot straight up outta side. Of course, a cub wouldn't do 3D well.

The bushed Norvel 25 wieghs the same, and makes about the same power as the hopped-up Magnum 25's that I have. I think the OS FP 25 would be about the same as the stock Magnum, and you could hop up the OS in the same way.

I also flew the FP15, and verticle was out of the question. My estimation is that for verticle or attempting hovering, a plane with an FP15 propably cannot weigh more than 24 oz, or about 1 1/2 lbs. Is that acheivable?

But the 25 should hover at least 2 1/2 lbs.

Please let us know how your mini laser 3D works out with the FP15.

Two years ago I build the plane on this picture. It is powered by Magnum.15. This plane is pretty good, but there is not power enough for howering. I will try a O.S.max .15LA next week.
wingspan 950mm (37.4 in)
weight 750g
If You have a interest, you can find a plan in .dxf on my web site, or mail me.

Hi Lada,

Nice looking plane!

But I don't think you will gain anything going with the OS 15 LA over the Magnum 15. They are both plain bearing engines that put out about the same power.

...Or did you mean an OS 25 LA?

Now that would make a noticable difference!

Mark

I've heard the Magnum 15 was a pretty strong running engine. Have you tested & compared the OS LA 15 to the Magnum? Is it much more powerfull? I will be suprised if it is.

750 grams is about 26 oz, if I'm correct. So it seems that I was wrong in my guess above, that a 15 might hover a 26 oz. plane, unless your particular Magnum 15 is really a dog. Maybe a 15 cannot hover ANYTHING??

If you can get one, I would try an OS FP25, or perhaps a Norvel non-BB (bushed) 25. They both only wiegh about 1.5 to 2.0 oz more than those 15's your trying, and will make almost double the thrust.

A 10x4 Kavan, Grish Tornado, or Graupner worked the best for me on the 25's, for thrust. I haven't tried an APC. The 10x4 Zinger loads it down too much. If you like the RPM, a 9x4 to 9x5 also works well on the 25's, especially the Norvel, which seems to like the higher revs.

Let us know how it works!

2krc.com has a 0.15 class mini 3D available in ARF.
You can do all unlimited 3D maneuvers.

Looks like a nice plane Nelson...but I went to the 2krc.com web site that you mentioned, and I don't see anything that looks like what you are flying in the picture. They only have large planes shown.

...or do you have to have a secret password to view the small planes?

Could you please tell me how to get to the page that shows the plane you are flying, and do you know if their planes are available in the USA?

Thanks for the info,

Mark

Last night i changed things slightly with my scratch built fuz. Its now called a Mini Magic. Should be covered by the weekend. All up dry weight is 1lb 6oz.

Neil

As you can see from this picture the receiver and battery are right down the bottom of the tail.
Balances one third from leading edge.

Wow...is the receiver & battery going to be totally enclosed in the tail when it's done, or are you going to have access to them somehow?

Also, is that the stock tail surfaces from the laser, too, or did you build them with the Fuse?

...Can't wait for the flight report!

Mark

I was going to enclose the radio in. Cutting a small hole won't be a problem if i do need to get at anything. The fuz and tail is all new. The ailerons will also have to lose about an inch on each side as they meet the wing to allow for the rubber bands to hold the wing on.

Neil

Hi Mark,
Magnum and OS max are very similar. Magnum has a ball bearings. My Magnum is pretty old (3 years of running every sunday, in winter too). It turns MA 8x4 11500 rpm. Os max.15la is new and turns 13800 rpm with APC 8x4. I hope, it will be better than Magnum. I will try it on sunday, if weather will be good.
OS 25LA can be good way, to get a power enough, but I am afraid about wing loading. Now it is about 32g/dm2 and landings are really gently.
On the picture is second prototype of my .15 powered 3d planes.
I love this small things.

Lada

Lada

I didn't know you already had both engines

After seeing the difference you are getting between the two (2300 RPM) it would definitely be worth a try! But I did notice you gave RPM figures on the Magnum with a MA, and used a an APC on the OS. Have you tried the APC on the Magnum? They are allot more efficient prop than a MA, and you might see the RPM's go up quite a bit on the Magnum using the APC, as well.

Let us know how it works out for you.

Mark

Hi Derickhere,

The SHOWTIME 3D was on display at TOLEDO show on the
CREEK HOBBIES stand.
Pretty nice design.I am not sure it's for a .15. Looks bigger.
May it's a visual illusion !!!

I send an Email to find out.

Keep you inform.

Phil
