Yeah, and that is a super nice setup too. I have a few of these. It is very quiet.

Yeah, I really like the Himax motors. Right now I'm running a 2015-4100 with the aluminum 6.6:1 gearbox and 12x6 prop on a 16 ounce 3dfoamy Pitts. My thrust to weight ratio is around 1.6:1. I'm gonna try an 11x7 prop next. Supposedly it will produce about the same amount of thrust, but it will draw less amps for longer run times. We'll see.

Thanks. I'm also running a himax 2025-4200 with kokam 3s2p 1500 packs. I have a TP 2100 3s pack for the funtana when it comes in.

OK, I can see where the more thrust you have the better off you'll be with 3D, but how much speed should you sacrifice for the thrust. I use motocalc a lot and tend to prop for a medium between high speed and high thrust, but this will be my first lesson in 3D flying. Thanks for any info.

Make sure your TP 2100 in Gen II

It is, thanks. 10-12C. Any thoughts on my question?

RE: Mini Funtana -electric....When?
 
Speed is really not a necessity in any true 3d maneuver. However, if you want to fly some precision maneuvers along with your 3d routine, sacrificing some thrust for a little more speed is okay. The pitch of your prop should definitely be 8 or less, though. Right now I'm running a 12x6 prop. Its definitely got more thrust than speed, but it has enough speed to do fairly nice loops. I'm going to try an 11x7 and see if I lose any stability in a hover. THe Mini Funtana comes with a 12x6 prop, which is probably a good starting point. The 11x7 should give slightly longer run times and a little more speed, though. We'll have to wait and see how it works.

Hang on guys. The Mini-Funtana's should ship from here within the next few days.

Woohoo! I've been checking the Horizon site everyday... I was starting to get worried. Thanks again for keeping us updated Mike.

I want to add the fillets. Will that be easy to do, releatively that is? Thanks.

MMcConville 12-13-2004 02:49 PM

RE: Mini Funtana -electric....When?
 
Hmmm. To do them correctly its more like next to impossible. You'd have to change the root rib. I'd just add flat profile fillets to give it the same planform. That should be much easier.

Dart373 12-13-2004 09:50 PM

RE: Mini Funtana -electric....When?
 
Thats what I wanted, just the looks :)

Why did they not come on this guy? Thats almost a trademark am I right? I am so eager to get mine :)

RC4 12-14-2004 08:03 PM

RE: Mini Funtana -electric....When?
 
If the fillets are what I think they are, they don't even come on the 40 size do they? I thought only the 90 size Funtana had them. They are a trademark of the Katana, not the Funtana. ;)

Dart373 12-14-2004 09:28 PM

RE: Mini Funtana -electric....When?
 
I think so. None on the 40, but thats what makes the airplane look good. Thanks.

RE: Mini Funtana -electric....When?
 
I checked Horizon's website today and instead of Not Yet Available it said Out of Stock under the mini Funtana. Does that mean they've gotten their first shipment in and sent it out to the LHS? I hope so, I'd like to be building this plane before Christmas!

MMcConville 12-15-2004 02:33 PM

RE: Mini Funtana -electric....When?
 
Yes. They should be shipping now.

Dart373 12-15-2004 06:25 PM

RE: Mini Funtana -electric....When?
 
How many shipped? I hope I get the one we ordered... Keith

ORIGINAL: RC4

FYI, the setup I plan to use will give me very close to a 2:1 thrust ratio. According to the Himax web site, the following combination will produce 42.4 ounces of thrust while drawing only 15.2 amps:

Himax 2025-4200 Brushless motor
Phoenix 25 amp ESC
Himax aluminum offset gearbox with 6.6:1 ratio
12x8 prop
3 cell LiPo

I'm a little skeptical about the 15.2 amps estimate, but thats what they say. I'm curious to see what kind of run times I'll get. Probably less than 10 minutes with a 1200 maH 3s1p Lipo. I may try a 3s2p LiPo if it will fit.

Whoa! 42 ounces of thrust? Do you think that's right? That's the exact setup I have to put in my
Funtana. I hope it is right!

RE: Mini Funtana -electric....When?
 
They claim 42 ounces of thrust, but I have no way of confirming it yet. Here's the link straight to the data table from Maxx Products. They don't specify the exact battery, just that its a 3 cell Lipo.

We got 4 in yesterday. they look great.

That's awesome! OK. File this under "Kids don't try this at home." Until today I was sorta in between airframes (one too many crashes with gws formosa -- you try sticking a landing on an 8 foot runway :-) ) so I have all these electrics waiting for my Mini Funtana --which came in today so I'll be picking it up tomorrow! I was curious about how much thrust I could get from this setup -same as yours- so I hooked everything up. I held the motor/gearbox in my right hand and operated the throttle in my other hand --really, don't do this at home, I have great health benefits at work-- and was able to completely let my right arm go limp while the 12x8 prop held it in mid-air... at 6' and 204lbs I wonder what my arm weighs? Anyway, are there any good ways to bench test for thrust without having a motor mounted in an airframe?

Let me know how your flies if you get it ready before I do!

BTW, have you seen the cobri 20mm gearbox? http://www.allerc.com/index.php?cPath=55

Sorry guys had to make mine glow... :)

Looks just like its big brother. I cant wait to fly it tomorrow.

RE: Mini Funtana -electric....When?
 
Yeah, I've seen pics of the Cobri's online, but never seen one in person. I've already got the Himax aluminum gearbox, so I don't plan to buy the Cobri. I won't have my Mini Funtana anytime soon. Supposedly my wife is getting it for my Christmas, but I think it will arrive late. Do the Astro Flight Watt meters measure thrust? You can measure it with the engine mounted in the plane. As long as you make sure the horizontal stab is hooked securely, you're fine.

Anyone have a good suggestion for an Outrunner type motor? I hate gear boxes. I was thinking of a himaxx 2812-850 or something similar.

RE: Mini Funtana -electric....When?
 
Gosh!!!!!!!! i Was going to do that!!!!!!

What engine did you use? i was going to go with a OS .10????? i have a .15 but cant find a pitts muffler for it!!!!!! What size tank? what reciver? micro servos?

Please tell me your set up... I want one but i want a glow also!!!!! I am getting mine tomorrow!! and cant wait to get started.....

noticed you didnt reinforce fire wall?????? cut the cowl????
