enough of the small engines

I was flying my Funtana 40S with a DA 150 till it just couldn't hover it. I am changing motors. ZDZ 210. I am really hoping it will do it. All up weight is 33.5 lbs. with the redundant system. 36 servos total. I was wondering how to get the weight down. Any help would be great. Oh I have a taller gear on it as well. I made it in the machine shop. 16" tall plenty of prop clearence.

Take care

Now this depends on what orientation you are going to mount the engine in... if you are going to put it sideways so the head sticks out the right side of the cowl and the muffler goes down, you will need to put all the radio gear in the left wingtip to couterbalance the engine cylinder. WES Tec micro servos should work well, although you will probably want to mount them in the left wingtip as well and run a pully setup to pull-pull style controls on the rudder and elevator through the root of the wing. Only use a 4.8 volt pack on these servos too, 6 volts will likely tear the hardpoints out of your elev and rudder on quick reflex moves with all the torque. Good luck, I am just getting my ripped apart airplane fixed and hope to be 3D'ing the wild .10 soon

No, not atall. It will be extremly nose heavy. If you add the aileron, elevator, throtle and rudder at the tail it will be beter. Id use JR 8411s for all surfaces and a 1/4 scale one for the throttle, ya know, these fistey .10LAs need lots of torque to open the carby barrel

I know this is getting a little off the subject, but I have searched for threads on this and couldn't find any and this seems to be a good thread for a question like this...
This may seem like a silly question....but has anyone ever tried installing the prop backward and hovering a Funtana with the tail up and the nose down? Would installing the prop back wards be enough--do I also have to start the engine back wards. Will I need more power because loss of efficiency? Please post pictures if anyone has done this.

I'm tired of the .72 in mine. The book says .32--.46 range. The 3250ST I have is in that range right? Where can I get a 14x4w eight blade prop.

yes........have a look here

Its not quite turning the prop around but it s a laaaf

search the funfly and profile forum for inverted prophanging

Ya two guys at the feild are doing this.
Man does it look cool when the airplane is flying backwards!!

I am going to try this with my new turbine.

David-Hope this helps

Also the motor does not need to run backwards as the prop is already on backwards.

drivercrazy23

just because the prop is on back wards doesnt mean it will blow backwards. all it does when you turn the prop around is make the good edge that should be going the other way go back wards. if you want to go backwards you have to get a reversed prop.

No, I have seen this happen.
The guy just put the the prop on backwards and he took off backwards!

I wintnessed this!

i might try that with my spa3dt.

The plane is gonna rip apart with that cox .049.Try a Cox .0000000000000049 at idle. Just make sure you get those big 500 oz servos for the engine. And the rudder elevator and ailerons need 100000000000 oz servos just to fly. Just worry about getting that nex 1x 1/2 prop from apc, and keep it at idle so u dont shoot upwards and break the fuse in half.

Here are some never-before-seen spy pics of my 3D nightmare motor... the COX TOC edition .098, which is an engineering marvel of not one, but TWO fire-breathing, nitro eating, firewall dismembering twin geared full competition nitrous injected EFI .049's. This engine is NOT recommended for anything less than full competition use by trained professionals. I think this is the same engine DMehalko(DM) is running on his. I think my Funtana is about to meet its maker...

HEY!!! That is the EXACT setup I am using!!!
But you really do have to be very careful with throttle managment with that much motor(s)
on that plane. I am running all Multiplex Jumbo servos but still stripped one out in an attempt to take off.

David

Abraxxas, you can't do that. A twin on this thing? What if it catches on? Everybody will want to overpower their planes. This is crazy! Please, please, please, say it ain't so. Not to mention if you put a 2 oz. tank on it, at the reduced throttle you are going to have to hover at, you will be taking up the middle of the runway for over an hour!!!!!!

Oh no, this can not be allowed. Shame on you for starting something like this. Bad, bad, bad.

I have already done it. I have a 4 cylinder on the way right now! 4 0.049's!!!!!!!!!

post pics when i ghet them.

Where do you get one of those TOC .098s? Don't think they have made it to the UK yet[]. I definately need one of them in my life

The ultimate torque rollin' machine!!!

Sprink

Is the balance going to be OK? At a guess you will need at least half a pound of lead in the nose.

3DStein

Im afraid I don't know the owner of this eligante machine, but I reckon it wud be about right, especially with the 2 servos per elevator half and 4 on the rudder!!

I think he put the 2 3000mah 5 cell packs up the front under the tank!!!

After much research I finally found the perfect solution to hover the funtana. I scrapped the front engine setup all together and epoxied a main rotor from a ratpor 60 on the top of the fuse. I ran a DA50 for power. The first flight I noticed that the plane would easily flat spin, but it still wouldn't hover really well so I cut away the rudder and mounted a tail rotor in the rear. Now I can hover til the cows come home . My next project will be to scrap the wings since they aren't generating much lift anymore and mount the whole fuse to a 12' jon boat I have sitting in the shead for a float project. A word of warning to anyone trying this project. Make sure you use high torque micro servos to keep the weight down, and take the evinrude off the back of the jon boat before mounting the fuse so that it won't be tail heavy. haaaaarrrr

This is how we've been flying them in Chicago. The .25LA seems to pull just fine.

Abraxxas

ROFL... I'll bet my TOC .098 would turn that prop perfectly... what style clutch are you using on it? I'll bet that does tail-slide autos beautifully!!

Ian.W

Try antonov in russia, they seam to like them. but areyou sure your propping it a bit lowly. id get one of the 100" W Eight blade prop with vairable pitch. just to be sure.

If i were him id use a one from your chevy. There light weight and you could use you 27th channel on your nice new JR PCM 63.

just be aware on th econdition of all your servos, use flightly check ups and only ust the bes dimons gears avalible and replace them every 3 flights

im a helpfull kind of guy aint i?
