Thank you for the information update Crash ...Sounds like you are having a ball with the Evo and that it working well for you ,,,,,Winter is setting in up here so I will not be able to test fly my 1.00 till spring it will be interesting to hear how well ( or not) the 14x6 performs.

I have a APC 14x6 K series on a ST .90 and it pulls well .... it also emits a rather neat sound when it unloads at high speed ... the flight line loved the sound.

Junky- sounds like your prop is slightly loose-and running lean will setup a preignition which can make the prop slip.
richen it up a bit - put fine sanding discs on surfaces of prop/spinner--if you see signs that the prop is slipping.

Blade...

Sorry, I still have not run the APC 14x6 on the Evo 1.00. I flew today, and had the APC 15x4 Wide off the nose and tried to mount the 14x6. The prop adapter nut bottomed out on the engine shaft before it could tighten against the prop washer and prop and I could not get the 14x6 tight enough to fly. My guess is that I need another thin washer against the prop so that the adapter will screw on tight.

I'll get to work on that.

I'm still having a blast with the Funtana/Evo 1.00 combo. 4 more flights with no problems.

Well I am happy to hear that you had a good day of flying with the Evo ... I found the same thing after I had balanced an new nose cone and then balanced the prop that the nut was to shallow to fasten the prop on.

I will try and make a thicker washer or just use the one that came with the cone and the washer from the Evo as well ...Let me know if you come up with some thing better.

BTW the prop was a new Master Airscrew 14x6 K.

Well heres what I have found with my new Funtana Evo 1.00 combo. I am using Omega 15% fuel and have flown both a 14x6 and a 16x4. The 14x6 is deffinatly not the way to go. The 16x4 seems to be too much prop. The plane will hover on this but it will barely pull out. The Funtana is a awesome plane, but I am thinking it needs a 15x4 or 15x5 to pull it properly. To be honest, I was a little dissapointed with this combo. But the motor is still new and will get better with time. I have a feeling this thing has power but you have to right on with the prop. I will keep you guys updated.

James,

I agree with your comments about the 16x4 prop. I could not get above 9,600 RPM's on the Evo 1.00 with it. After consulting with the Horizon folks, I was told that the optimal RPM range begins at 10,500. That's when I put the APC 15x4 Wide on the nose and have been having a blast ever since (see above posts).

I can get about 10,550 RPMs on that prop and the Evo 1.00 is still running slightly rich. As the engine has been running over time (now with about a gallon of fuel put through it) the top-end RPM's have been increasing somewhat, but the low-end idle has been getting dramatically better.

I get hovers on my Funtana 90s/Evo 1.00 combo at about 55% throttle, and can pull out of a 0 speed hover to vertical climb at 100% throttle. The climb is a bit more brisk now than when I first got the engine, but it is not exactly fast. It is still much better than the Saito 100 that I had on my Funtana 90s when I first started flying it...even with the extra weight of the Evo.

All of this flying has been with Omega 15% fuel.

Thanks for the warning about the 14x6 prop. I won't even try it, now. If you end up putting a 15x5 on the nose, let me know how it goes.

Blade47

Just a bit of information .... I have found that the Front washer off the ST.90 will fit the EVO 1.0 perfect when placing a 14x6 prop on with a spinner and short adapter.

I hear there is a report on the Evo in RC review ? has anyone seen it? and if so what did they report on it? I don't get the mag up this way.

For those of you flying the Evo 1.00, what prop would be best for scale aerobatic flying....not 3D? 15x6? The plane is a Vectorflight 66" Edge 540.

Hi, are you guys still flying the funtana90 with the evo 100? If so, how is it going? I just put 1 together and its toooo cold to fly right now :>( . I have a half gallon of fuel through it on the ground due to the itch to fly it lol.[>:]

Hi Guys:
good reading this thread. I just purchased an Evo 100 for my 82" Me 163. It should be around 9/10 lbs. all up and I am still trying to decide about the prop. I obviously not interested in hovering but rather in good speed and pull for military type flying. I have a 13X6 and 14X6 APC that I was thinking of trying, what ya think. Also how thirsty is this engine? What size tank do you use for what flight times?
Thanks
Frank

On the test stand with a 12 ounce tank wide open and a bit rich I timed out to 8.5 minutes using a 14x6 APC ...that was new ..I would have to time it again as I have about 16 flights on it and would think it has a better fuel burn now,

I use a 13x6 APC on my MIG29 and 13x8 APC on the SU27 and both are very fast with the 13x8 being faster... I would like to try a 13x9 this summer.

cheers

what is the best plug to run in this engine?I'm having trouble with mine dead-sticking intermittently

Blade47

Stick with the Hanger 9 Super plug ..I even use them in my GMS .76 and .47 work well

I have a 100 in my 65" Yak and love it except for one thing... it bogs out when I try inverted spins. I can hover it, roll it, do long inverted lines... no problems. But when I try and inverted spin it bogs out rich when I try to apply the throttle. Things I've checked:

Clunk is free and mobile.
Tried Dubro and Hayes tanks
Low end is tuned to 250 or so rpm rise on pinch test.
Top is about same (sorry, no tach #s)
Tried Hanger 9 plug, OS A3, 8, and F
CP 10% fuel and a PZ 15x6 wood prop.

If I let it deadstick after it bogs, after landing I find fuel throughout the line right up to the carb; it's not starving for fuel. It's just a classic rich bog-out but only when inverted and under spinning forces. Since the problem is lessened by using the longer plugs (OS F and Hanger 9 "H" plug), I'm guessing the plug is getting drowned in fuel when I apply the throttle.

Other than this bogging, it's a great engine and very reliable in all other manuvers. Any other ideas?

whats the best fuel(how much nitro) im running 15% omega and cant get it to run well enough to trust it in the air.i was told 5% would solve the problem,what do you guys think????????

Blade47

I am using 10% and works well spinning either 13x6 or 13x8 APC

i tried 5% cool power and it seens to be working,not one deadstick but the mid range is very rich.14x4 prop os f plug

Well, I've tried about every combination I can think of now and find the best running I can get is the Hanger 9 plug. If I go any leaner on the idle screw, it dies lean in a hover. I tried going to a uniflow style tank set-up and that did nothing also. So as it stands, the Evo 100 will put my 65" Yak through its paces with ease on every manuver except an inverted flat spin. The mid range just won't lean out for me and it's bogging out the engine when the throttle comes on while the plane is spinning. It's frustrating since the motor is so nice in all other aspects of flying the plane.

Has anyone ever tried another carb in this motor?

Blade47

I have worked with the low end and found this works great for transition .... Tune the top end for best running with the prop your using ...then shut down and with the throttle barrel FULL closed turn your ( count the number of turns to full closed for later reference )low speed closed then back out to 1 1 /4 turns ...you should then be VERY close within 1/8 a turn eight way for a good trans. give it a try you may like it


Lets us know if it works for you.

I also use Hanger 9 plug

after a couple long flights today im finding that the mid range is going to be a problem.i can not hover,it will not transition well enough once im in the hover.it hasnt quit since i started using 5% cool power but this mid range issue has to be solved.if i cant get it done i will switch engines.ive tried 16x4 15x4 14x4 15x6 props os3 os8 osF plugs

i took off the evo carb and soccer kicked it.replaced it with a super tiger carb and what do ya know,100% better.

Berwyn Bill

My Feedback: (16)

Is that the carb from the ST90? I might have to give that a try. Thanks!!

it must be i didn't ask at the hobby store what size it belonged to.i said what do you have that would match this evo carb and he handed me a super tiger carb.he only charged me 20.00
