Thanks for the link dude. That's just the ticket I believe, after researching the carbon fiber I would prefer for them to not delaminate, and since they absorb less of the impact I don't want the fuse to crack. I'll pick up a pair of the aluminum gear from TNT.

It seems like the fuse is built kind of shoddy. I was thinking about reinforcing with some triangle stock and putting some reinforcement blocks in the landing gear area. Did you add any reinforcements?

If there's any question in your mind about the need to reinforce the gear mounting area of the fuselage, just spend a bit more time on this thread.....[X(]

And yes, I did reinforce mine. Still knocked it out one day on what turned out to be a fairly high speed landing due to some radio issues (new tx and I flipped the wrong switch) I was having making the model hard to control. It was down and rolling on a full scale runway where we fly sometimes, and all of a sudden the thing just folded. Still not sure what happened that day but the full scale runway is a bit rough for models and it was going at a pretty good clip. I reinforced it some more when I fixed it...... lol

Hah - I've read about the need to reinforce, but haven't spent too much time on this thread. I'll skim through it more thoroughly. It really looks like it's poorly designed.

Thanks for the tips.

I just bought a New In The Box FuntanaS 90 off ebay for $127.00. Reinforced the landing gear block by building a light ply box and using epoxy, drilled and pinned the firewall on all sides and from the front, epoxy quarter inch stock around the motor box on inside and outside, replaced the tail wheel mount with a dubro tail wheel assembly, reinforced the wing servo mounts, raised the throttle servo by 1/8 inch so servo would not set on lower stringer. Will be mounting a saito 1.00 in this baby. Now have the S90, X100 and 2 of the new Funtana 125's. The X100 has a Saito 1.00 in it and the 2 new Funtana 125's each have the Saito 1.25 engine. I do love this airplane. I lost my original S90 last summer. Have all the pieces and will probably rebuild it this coming winter.

Hi,

My tail wheel wire broke on my Funtana 90. What would be a suitable tail wheel assembly to replace it with without removing the rudder? Was looking at this part: http://www.horizonhobby.com/Products...?ProdID=HAN332

Any suggestions?

Thanks,
Erick

CrazyErick: I would suggest the Sullivan tail wheel assembly S860 (5-12 lb airplane) or the S861 (10-22 lb airplane). I have 4 of the Funtanas and have used this tail wheel bracket on all of them. I think the tail wheel bracket you are suggesting would be too heavy.

+1 for the Sullivan unit. I used four socket head wood screws (rather than trying to get the included T-nuts installed with machine screws) to mount the thing with the holes hardend using CA. Don't forget to pick up a suitable tailwheel as well....

Well you lucked out catching me as it's just before Midnight here but I'm watching an old movie.... lol

Went and put a measuring device on mine and it looks to be a 1 1/4".

http://www3.towerhobbies.com/cgi-bin...?&I=LXFU88&P=M

I don't think it comes with wheel collars either???? Been too long since I put it together.

I finally got some time to work on my plane. Any of you guys got pics of your Sullivan setups? I'm just curious if you just glued the bid that went into the rudder? Also did you use CA or Epoxy? Was wondering if I should reinforce the part of the rod from the 90deg bend into the rudder back to the spring?

What I typically do with this type of tail wheel where there is a spring attached to the rudder by a 90 bend going up into the rudder is to just put a double layer of iron on covering material over the part of the wire that goes into teh rudder. This makes it easy to repair, replace if required. No glue required.

Couldn't remember exactly what I'd done to mine, had to go look....

I just made the 90 degree bend in the wire to go up into the rudder, poked a hole in the bottom of the rudder, pulled it back out and put in some thin CA mostly to toughen up the balsa and shoved the wire back into the hole. Then it looks like I've got about 1/2" of medium CA on both sides of that wire from where it goes into the rudder running forward. Been there for a long time with no issues.

I looked at my S90 tail wheel install. I drilled a hole in the bottom of the rudder large enough for a small piece of brass tube to be inserted. Epoxyed the brass tube in the rudder. Bent the tail wheel wire at a 90 degree and inserted it. Been using this setup for about 4-5 years now.

For what its worth I always use a Sullivan tail wheel http://www3.towerhobbies.com/cgi-bin...&I=LXFV47&P=SM
and get good results. I also take the little red plastic tube from a WD40 can and insert it into the rudder and then bend the spring into the plastic tube. No glue required, I use a small piece of tape over the spring end to keep it in place.

I use a Sullivan tail wheel on mine as well.  Works great.

I've reinforced the frame quite a bit, what is everyone's opinions of switching over to gas - DLE30 or DL20?

I still fly my f90 - Moki 135 out front and looking quite beat up. It must be about 7 years old now. Am going to indulge in some trimming and try make it fly a bit smoother - rearward CG makes it very hard to land at the moment.

Anyone else still have/fly their F90's??

Yep. Sure do. I have the Funtana S90, Funtana 100x, and 2 of the Funtana 125's in my hanger. Regularly take all three models to the flying field each time I go. I love my funtana's. All have Saito 1.25 engines and one has the SAP 1.80, 30cc gas engine with a DX8 radio system with all telemetry to date.

Hi John - how do you set up your planes?

If I fly it every weekend I can handle my F90 as it is, but my flying is far more limited than that now and I find mine too twitchy to be enjoyable. I also find mine very hard to land, it balloons at a touch of up elevator making it very hard to land unless its done harrier style. I am thinking of moving the cg further forward to help it glide better and lose the elevator senistivity. By way of example, mine climbs at 25deg when inverted, which is no doubt a sign its cg is way back. I set it up like that initially to make it easier to do wuild aerobatics, which it does excel at.

I'd be interested how you set yours up. I want mine to be a better balance between precision and 3d aerobatics and easier to land.

All of my Funtana's have the CG set to balance level at the mid point as recommended in the manuals. The only complaint that I have is that all three models tend to drop the tail the slower I fly. So, I have to keep a little throttle applied on landings or feed a little down elevator in to keep the nose down. Most of my landings actually are tail wheel first, with the main gear about 2-4 inches off the ground. I have done a few main gear, tail off the ground landings, but prefer the first way. Any suggestions as to how to stop the tail dropping with this setup?

I sold my F90 to a guy clear across the country two years ago. Mine had the Saito 150. I'm in California, I shipped it to West Virginia via Greyhound. It got there in perfect condition. The new owner was "stepping up" from smaller airplanes and this was his first real 3D capable airplane. I guess he is having a good time being the big man at the club with the most badass acrobatic airplane. He emails me once in a while and thanks me for such an awesome aircraft. I have moved on, don't fly nitro at all any more. Gone all gasser, and I have a 86" 50cc QQ Yak and a 121" TT-TOC Yak with a 3W157CS. I have several e-powered foamies and otherwise too. Once I started flying gas, the nitro thing just became a horrible messy job. The larger birds fly so much better it's not even funny.

If anyone is interested here I have not put much time on my Funtana 90 recently. I would sell it ready to fly for a good price if anyone is interested. Hardly any flight time at all on this bird with less than 1/2 gallon of fuel thru the motor. Runs and flys great! Updated Version 2 wings, like new Saito 100 FA w/Muffler ALL DIGITAL SERVOS
5) HITEC HS-5975HB’s & 1) HS-5475HB DIGITAL SERVOS
Futaba Switch & GP Charging Mount
NiMh Rx Battery
Taller Custom Alum. Landing Gear by TNT
Spinner, Prop & Wing Bags
Just soot me a PM
