I was wondering the same thing. Or maybe a OS 1.20AX 2 stroke.

Don't hate on the 2 stroke!

I'm itchin to get one of these. Will the OS 120 AX fit in it ok without any firewall mods? I've never seen a 120 Ax , but it looks big........Any thought? Thanks

I really like my F90 with a YS110 setup so I thought I would try something a bit different in the 100X. I set it up with Zenoah's new 20cc gas engine with electronic ignition. I put aftermarket (graph tech) landing gear for additional inch of lift then put titanium axels with Kavan 4 inch tires on it for another 3/4 inch lift. the new gear weighs the same as the stock CF setup but I had to loose the Wheel pants. I’m on ruff grass and this setup is working well. The Zenoah 20 is turning an APC 16.5 X 5 prop out of the box at 8950 RPM. An 8 Oz. tank is giving me about 30 min of hard run time (more than I can say for the ignition battery but that is a different story). It has less power than the YS setup but it is very cool to run all day on $2.00 in fuel instead of $60.00 for the same time in the air with 30% nitro. The motor just bolts in with 3/8 inch of spacer required. I had to mount the Rx batt., behind the canopy to get the recommended CG. It will hover but no pullout left to speak of. I am at 1.1 to 1 power to weight ratio. Rolling circles down low are a hoot. it sloooow rooools very comfortable on the deck full length of the runway as well. It's very different than the F90 but definitely a keeper.

I see some had the same idea about support wires on the fin/stab. Are they standard or a mod? I dont remember seeing any in the box. Looking at the aspect ratio of the stab,it looks like you better get good balsa or could have stabs falling off without some extra strength-I might go for CF tape,but, no,would have to cut that beautiful covering job,couldnt bare to.Wonder if I could use kevlar or something like that?

butternifedge

I'm sure it was a bit overkill, but I took 1/2a horns and cut all but the first hole off. then I took carbon rods with titanium ends and screwed sullivan clevises to them for stab to fuse support.

So what about the EVO 1.00 2 stroke? Whould it work well?

OR better yet an OS 120AX?

Hello all, been flying mine for 2 1/2 weeks now. Got rid of my F90S. First I must say my F90(which I purchased all together, lousy build job) was way underpowered (Saito 100) and always tail heavy. I got sick of that plane and scrapped everything except the 5 5945 servos. The 100X IMO is so much better.

I ended up putting a YS 120SC (34oz)up front with pitts none smoke, this thing has more than enough power and quiet. I cut 5/8" off firewall to get the correct length out of the front of the cowl.I'm on my second gallon of fuel and the engine is just about broken in (had a complete overhaul from YS)spins APC 17/6 around 8900-9100 the guys at YS said to stick around 9000 with that prop.

I put 2 1200 NIMH batteries right next to the fuel tank on either side. At first I had them as close to the firewall as possible. After a week of flying I ended up moving them back around 3", still in front of wing tube. The RX is behind the fuel tank and it balanced within the recommended fiqures. No idea of the wieght.This thing spins fast and straight as an arrow.

I can honestly say I love flying this plane I feel they did improve the F90 ( moved the wings back and thinner air foil) Not to forget CF landing rear (sits alot taller) and wing tube. All this FUNtana for 209.00!!! My opinion might not mean to much for those of you that have a great flying F90.

Good luck with building and I'm sure you will be pleasantly surprised... Got the plane on a Monday and first flight on Friday same week. I'll see if I can post some pictures.

Based on past experience if you try an APC 17x4w instead of the 16.5x5W you might experience more pull out in a hover with the zenoah. Both props seem to load an engine about the same on the ground statically but the 17 x4 will unload easier in flight. Don't know how much time you have on the zenoah but it will increase in performance a bit until at least a couple of gallons of fuel has been run throught it. Curious as to how a 16 x4w might act on it.

Thanks for the input Zonk. I have a 17 x 4w because I have used both on the YS 110. I flew a couple more flights list night on the Zenoah 20 with the 16.5 x 5 and it IS a bit weak for the X100. Only have a half gallon through this one though. The 16.5 x 5 is still a little slow for airspeed WOT. I will definitely try the 17 x 4w but my fear is it will slow it even more, but will be ok if I get even a little more pull out. I just ordered from LHS an EVO26 and a carbon tuned pipe for the Funtana 90. My guess is I will like this much better and end up with the same on the X100 in the end. That’s ok cuz I wanted to try the Zenoah on a 60 size tiger moth for a Sunday flyer. Again, thank you for the input.

Did you weigh it?

butternifedge

It is a bit heavy. It came in at 10 lb and 5 oz. RTF less fuel.

MIXMASTER

My Feedback: (15)

Could you guys give us a weight-I went with the Sa 1.25 because its 1/2 lb lighter than the 1.50 and hoping the 100X is another 1/2 lb lighter. I guess the 1.25 should give enough power for hover in a 8-8.5 lb frame. From previous experience/planes,the 1.50 would be better for 9# & up. To me, the weight & wing loading will determine how a plane transitions from stall to normal flight,the slower the air speed required to do that,is better. I'm not too worried about rocketing out of a hover,I only need some reserve power on top to pull out. It is easier on the engines though if you dont need full throttle to get out,back to the weight again. In 3-D, everything matters!

MIXMASTER

My Feedback: (15)

Do you have spinner,pants,APC,pilot?? Thats HEAVY man!

butternifedge

It's real heavy. The Zenoah 20 is a pound heaver than glow setups and the ignition sucks. I mean sucks the power from the batteries. I am running 2 JR 1650MHA batts in parallel to get a 3300MHA pack for the ignition alone. That gives me 2 20 minute flights and recharge takes about 1800MHA to top it off. I’m running a lopo and 6volt regulator on RX and servos (lite servos JR9411 all around). no pilot. I did the maiden in 16 to 20 MPH winds and it flew surprisingly well, probably due to the additional weight of the gas engine. I'm thinking that if I am going with the weight penalty of the gas setup, I might better go with the EVO 26 and a tuned pipe and get the additional power to offset the weight. The air frame seems to handle the weight well. The EVO\pipe setup will actually be a bit lighter since the 2 engines bare are about 1 oz. apart and I won’t need a boat anchor for the ignition battery on the EVO. Also the Zenoah is giving me about 11.5 LBS of static thrust and the EVO/pipe setup is supposed to give me about 16.0 LBS of thrust, putting me back into 3D setup.

butternifedge

I forgot to mention the batts are NMH and no spinner but i have an aluminum prop nut on it for the starter. no wheel pants but the gear and tires are aftermarket for ruff grass but total weight is the same as stock with the wheel pants. No pilot.

im reading the review in the september issue of model airplane news. wow what a plane, i got to get me one of these.

I have been flying my funtana for about 6 months with the evo 26 on an in cowl muffler.it will barely pull out of a hover and i have tried props,fuel, tuning,and balancing with no effect.i asked a couple friends of mine that have far more experience what can i do if anything and one said get the pipe and the other said the pipe wont do anything,well i got the pipe from horizon and flew it for the first time yesterday and WOOOOOOOOOOOOOOOOOOOOO night and day.instead of hanging on full throttle it hovers at half and goes vertical like a rocket.best 80 bucks i ever spent.

I wonder what the difference would be for someone like me at 5000 ft.?

butternifedge

Now THATS THE KIND OF POSITIVE REINFORCEMENT I've been lookin' for. I just ordered the $160.00 version Skorepa tuned pipe in CF at 3.8 OZ. for weight. Thank you for the great update on the tuned pipe difference. Sounds like I didn't need the weight savings in CF if it pulls that good. I'll buy the aluminum for my other funtana upgrade and save the cash.

butternifedge

Jawbuy,

What prop are you running on the pipe? Have you compared more than one prop for performance yet? Sounds like the pipe upgrade made it a new plane.

Good idea,lighter than 2/56 rods,no tensioning needed,easier than using CF tape. I've known some guys who insert CF rods or tubes into the stab, but ,again,that means cutting covering,good if you are kit building,not on this beauty!

killuminati

I am in the process of using that same set up. Can't wait!

butternifedge

Be sure to give us a flight report on that setup after the maiden.

Looking to to the Funtana 100 with the Evo 26 and pipe setup as well...currently have a recovered 90 with a Saito 180...want to give the gas a try...would like to see some video pr pics of the Evo26 and pipe setup.

ChopperMan33

I am thinking of getting a f100, I currently fly a f40 with a os.46 in it and jr 537 servos. The evo 26 looks like a great powerplant for this but what servos would be work best and what would get you by ok for minor 3d flight maybe with some progression.
