Funtana 90 w/Evolution 26GT 1.6 gasser
Hey Dick Hanson, how about a flight report? I got all the pieces to put mine together now. Anyone else have this setup?

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
I would be interested to hear what the bare weight of your F90 is. Do you plan to weight it? Just seen a very positive flight report from Dick in another thread.
http://www.rcuniverse.com/forum/m_3649232/tm.htm
Dick Hanson:
"Well buckaroos - I went out in the 32 f weather and flew my new 90Funtana -with the Evolution 26 n Skorepa pipe - and a 18x6 Skorepa prop
The radio is an old JRZ512 bit and the servos all were the new JR 125 Sports very cheap but all metal gears I set it up for max servo rotation and max throws (over 45 degrees on elevator) and used a 2700ma 4,8 v pack .I balanced it smack on the recommended spot. all up 10 lbs exactly-- less fuel.
The plane was never allowed to reach full speed in level flight -not even close -but the tach LED read 4685 which means 9370 rpm was hit at some point in the flight
Performance is simply outstanding - hover power is extremely low and also extremely responsive -you can idle power up to the hover - hover - leave stick there and the hover stays put - touch power -it climbs -hit power -it goes straight up instantly
So the 10 lbs /1100 squares is as guessed -an ideal sweet spot for the 26 Evolution -piped -here at 4500 ft.
I ran thru a bunch of landings just trying to find ideal flare and speed - - it takes very low power and the tail settles to about the same angle as it sets on the ground in a nice approach-then just tickling the power- the model simply holds that angle and rises or settles. I found it hard to wheel land as the speed will not bleed off enough till the deck angle rises .
What a blast to fly -blurr speed rolls at low speeds - deep Harriers, as even as can be , etc..
If the 1.60 OS setups are any faster -and they could be -I don't know where you would use the extra power -on this model - it likes to do everything very slowly -power instantly recovers it from any attitude."

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Obviously, I stuck the write up in the wrong place .
The plane is an absolute hoot .
My son said "it flies just like a foamie!"
It does == you can simply use power bursts to flit around - kick the rudder with power burst and it just wheels around -level wings - little tuck
It does tuck tho in knife edge loop.
But all in all , a better yank n bank low speed machine than the Showtime -the Showtime is far smoother 'n likes more speed.
The Funtana tho -on this engine and pipe is perfectly matched - for slower speed goofing off
I don't count the walls n blenders as much - those are just abuse maneuvers but this onecan be slowed to nothing with full up and it just falls as smoothly as you please then firewall it and it instantly goes straight up The response is the real standout feature .

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
That's great to hear Dick, I'm all excited now! I was talking to Mike McMurtry today when I went to pick up the engine, and he was interested in what you had to say about yours, concerning the 3D power. (ie half throttle hover, punch out, etc.) I had kicked around a couple of other combinations, but when I saw your posts with the EVO 1.6, I settled on that since I wanted to move to gassers anyway.
STG, I will post some weights for you shortly.

Bare weight of all the parts in the box is 5lbs. 7oz. or 5.45lbs. without removing the plastic bags from the landing gear parts, fuel tank, and the hardware package. I'll post the weights of the specific engine pieces soon.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Mike I know that the pipe is a big unknown for some - but seriously -I would not even consider it without the pipe -
I know it will run well on a in cowl muffler - but there is 30-50% POWER difference in the two setups
Don't believe me - ask the people who make and sell the engine or study any good rpm/ power absorpsion charts.
I did nothing -but attach the header and pipe- add a 18x6 prop -fill it with recommended 32-1 Mobil -from day one -and fly it
How heavy -
I did a 260 at 11.25 lbs 1135 squares -vs this model at 1100 and 10 lbs.
The difference was very noticable ! Tho the 260 would also pull away vertically - it was working-harder
why?
over 10% difference in weight
I also did the Showtime at 900 squares a blast to fly!which as strange as it seems weighed 4 ounces more than this model why?different pipe!
I am using the prototype new Ed Skorepa Carbon Fiber pipe designed specifically for this engine.
The response is identical - it is a little over half the weight (under 4 ounces) and is more quiet due to different after muffle design and a longish stinger .
If you really want a more involved look into all of this -- get the new 3DFlyer mag - I did a review in there -on the Showtime -this engine and it's stock pipe.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
yes
kit--5.45 lbs --
well the total engine/ cf pipe/ ignition /small 4.8 batt =48 ozs so thats 3 lbs
add to your weight thats 8.5 lb so use smaller tank- loose an ounce - I used 5 , JR SPORT 125 servos at 1.5 ea=7 ozs now we are at 9 lbs --add prop, rx batt some bits of foam - cut out floor from canopy (I did) add a 710 rx, a couple of switches -- loose all of the ball joint linkage -use Sullivan 4/40 clevis' - you should be where I am.+- a bit.

Dick, I don't fly my F90 any slower than my other planes.---I don't race though.
If the 1.60 OS setups are any faster -and they could be -I don't know where you would use the extra power
Your EV1.6 with pipe is putting out very close to the thrust I would expect a 1.6FX/pitts to put out. This is better than others are doing with this motor/pipe.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Well -I ran glow setups for maaaany years and this is the first time I got close to par with glow fuel setup in similar sized engine.
Nitro is a huge advantage. I did not expect the results either.
If I were to go back to glow fuel -it would be a piped ST 2300 on spark ignition and 5% nitro 20%oil. blow the fr---doors off any OSFX
9000 on 18x10 APC

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Here's what I came up with on the powerplant component weights.
Engine w/plug - 33 oz
Evo pipe - 7.6 oz
Ignition - 4.9 oz
Header w/hardware - 4.4 oz
4.8 battery & switch - 4.2 oz
That comes to 54.1 ounces or 3.38 lbs for the complete setup including a required ignition battery.
With my (HS-645MG) servos, I'm anticipating 10.5 to 11 lbs turn key.
For what it's worth, The new Super Tigre G-2300 I bought for this weighs in at 38oz with the muffler.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Your weights for the Evolution are close - pipe n header is 11.2- hardly anything to argue. (I lost 4 oz w/new pipe)
The required ignition battery- if you do any searching - is under 3 ounces -a 900ma in a modern NIMH is good for 6-8 flights.
There is no need to buy Lithium or spend money on fancy regs etc..
The radio batt can also be a new JR or similar High output NIMH at 1500--1650 mh . I would bet Mike McMurty has the latest JR cells. The ignition cells -I got from my electric model stuff -Cheap Batts.
My kit was a busted return , so it was REALLY nothing special---as noted -I used the pushrods but not the clevis or ball links saved a little there
The tailwheel -is also a bit of delicate thing amd I would suggest getting some cheezy soft foamy ones to act as a buffer for thumping the tail down first.
But using the stock motormount and a 12 oz light tank - cutting out the floor of the canopy (it does no good structurally) use a mini throttle servo and a wood prop - will put you at 10 lbs - It did for me
If you have money to blow -buy a CF wing tube -but really not worth the effort in my book
A landing gear by EdSkorpa could be used to replace the aluminum one -his is Carbon fibre but totally unlike the ones you see in kits .
It also is not cheap.
My plane at 10 lbs needs no weight reduction so I won't gofurther in replacement but 11 lbs - is noticiablly different than10 lbs so be careful not to add any extras.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
My YAK less the pipe?
No better than the others with mufflers in cowl-
and "no way" I would do it.
The plane was designed for it . I just made a header and assembled it.

On an 11 pound plane (Gliles UL) I plan now to put a Mac pipe on 1.6FX and hope to run a 19x7 Skorepa. If it will turn in the mid 8's with the pipe I will be happy and it will equate to about 4hp. On an 11 pound plane (Gliles UL) flying IMAC (slow sequence, not fast like the pattern guys) and 3D mix I expect to average less than 1oz/min fuel usage. I do not think I will be at full throttle for more than 5-10 seconds at a time.
Balsa Steel,
If your Funtana is 5pounds 7oz you got a very good one. If you are willing to shed those tires and wheel pants there is 3.5oz right there. So then you would start at 5 pounds 4oz. With Stock pipe you should come in at 10.25 pounds and should have a very good flyer.
I think the best batteries for this set up would be http://www.cheapbatterypacks.com/main.asp?sid=327570
2/3 AA CB750 @ .5oz ea x4 = 2oz
2/3A CB1150 @ .7oz ea x 4 = 2.8oz
A CB1800 @ 1oz x4 = 4oz
These cells are intended for high amp draws so will take anything your plane will throw at them. The prices are more than reasonable and you can have the pack made in any configuration you choose. I have all the packs above and they are great.

How do you think your EF Yak would be without the tuned pipe? Yes, I know the pipe adds a lot, but i'm just curious. Looks like EF is coming out with a 85" Edge and Extra.

_________________________
You were not wondering how the 68"er would do with the Evo26 and in cowl muffler were you? Dick is right, buy all the numbers I have found the 1.6MVVS without a pipe will only provide about 12 to 14 pounds of thrust. The 68" yak would come about 9.5 pounds if you made it as light as possible(5 pounds bare weight same as these f90's). Not good for power 3D.

The choke setup for the 1.6 -easiest so far-just twist to choke -flip - then let go.
I used a sturdy horn and #2 skt head short self threading screws

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
What sucks is where do you stick the big old long pipe on most planes?
I had a friend that had the mvvs version on pipe on a 1.20 US, sucker hovered around 1/3 stick.
Id like one on the giles 202 but dont know where the pipe would go.

I would put a 1.6MVVS/pipe on the Giles if it was 5 pounds bare, but it is 6.5 pounds bare. That would put the plane at 11.7 pounds. Fine for IMAC and some 3D, but not much "get out of trouble" power.

Be sure to pick up a couple of his 18x6 props while you are at it. They have produced the best results so far.

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Comon guys, lets see pics of this puppy w/ the evo. I just got the 58gx and it going in a 30% TOC 1 Yak. I lost my funtana this fall due to a battery going south and was wanting a new one and this sounds great. What is it exactly that I need to due to put this plane together w/ this evo motor. You guys are getting me very excited. Maybe even build it over Christmas break and drive 8 hours to the south to fly it

RE: Funtana 90 w/Evolution 26GT 1.6 gasser
Powerwise it is extremely good - -not just relative to some 90 setup -this setup is about as much power as anyone can use in the Funtana. It looks like all the rest -except for the engine and pipe -- here --------
I have not -and may- not try full bore level flight - It seems pointless full bore straight up is quite fast. You can start fast rolls straight up from a hover. and it just accelerates.
FWIW - I can still --thru getting picky -get this thing to under 9/75 lbs .mainly swap out gear (no CF) wheels & use smaller Rx pack-
