RE: Evolution 100
Have you flown a Funtana 90 with a Evo 100 (prototype perhaps)? How do you think it would (or does) compare to the performance of the Saito 100 on the Funtana?

RE: Evolution 100
Have purchased and have almost completely installed the Evo 1.00 in my Funtana 90s (had a Saito 100 in it and it pulled it around just fine on a 16x4 APC wide prop running 30% heli fuel, but there was no unlimited vertical...it did hover at full throttle, though).
The Evo 1.00 mounted in exactly the same mounting holes on the engine mount as the Saito 100 with only about 1/8th inch (maybe less) additional length from firewall to spinner backplate than the Saito. Muffler mounted ALMOST perfectly with only minimal relief needed in the sub-firewall (small hole) for the end of the threaded rod (and nut) that goes through the muffler housing from one end to the other that holds the two pieces of the muffler together. A new throttle push-rod was needed, and it was bent (angular bends at two locations) around the cylinder casing to accommodate the new throttle arm location at the front of the engine without the need to drill a new hole in the firewall for a new pushrod location. I used a stiffer push-rod to make sure there was no slop or play in the rod between the servo and the throttle arm through the entire necessary servo transit range.
I purchased a new cowl and have not cut it yet for the Evo, but it looks like the muffler is going to need plenty of relief in the cowl.
A new prop adapter was needed for my Tru-Turn spinner as the adapter for the Saito was not going to fit the standard threads of the Evo 1.00.
Will cut the cowl at some point over the next day or so and take it to the field this weekend for a test flight. I'll report back as soon as I can with the results.

RE: Evolution 100
Please post some pics if available of the relief hole in firewall. I am mounting my 1.00 now in the Funtana and jsut want to see how much you had to take off and how you did it.

RE: Evolution 100
I'll work on those pics as soon as I can.
The hole in the sub-firewall was simply drilled with a large drill bit. I made the hole larger from side-to-side because the engine will most likely vibrate that way on the mount. I got a bit carried away and probably made it larger than needed. I then glued an epoxy-covered square piece of 1/8 ply INSIDE the fuse at the sub-firewall to cover the hole since the end of the muffler only needed to penetrate the sub-firewall about 1/8th of an inch - which is exactly the width of the ply with which the sub-firewall is made.
I cut the cowl and it came out perfectly. As I had expected, a large amount of relief was needed for the muffler. I cut a hole in the cowl above the cylinder head which was exactly the same size of the top of the cylinder head. I figured that the cooling this allows, coupled with the cooling I will get from opening up the bottom of the cowl for the muffler (plus a little extra for good measure) will pretty much guarantee a cooler engine. I had to cut the usual holes for the needle valve, and the quick-fuel valve at the top of the cowl.
I'll get pics of the cowl, too. You may not care, but I'm proud if it, so I'll show it off.
When the prop adapter arrives (hopefully tomorrow), I'll be ready to fly this weekend.
Good luck with your installation! Don't worry. It'll be a snap!

RE: Evolution 100
Well...here are the pics.
Hope all went well with your installation!
I moved the cowl back further than the one I had on the Saito 100. The mounting holes I drilled on the cowl that held the Saito were too close to the edge of the cowl for my comfort. The cowl mounting screws actually began to chip away at the cowl even closer to the edge as I put more flights the plane. On the cowl for the Evo 1.00 the prop and spinner will protrude from the cowl about 1/4 to 3/8 inch due to the combined impact of the cowl being further back, and the Evo 1.00 being longer than the Saito when put in the same engine mounting holes as the Saito.
I put the prop and spinner on today with the new prop adapter that came in the mail, and it still looks sharp!

RE: Evolution 100
Loooks exactly like mine but bigger hole in the bottom. What prop you think will work right. The manual says a 14x6 for starting but I was thinking bigger. Like 16x4 or something

RE: Evolution 100
Some of the on-line information at Horizon Hobby puts the top-end prop range at 16x4.
I'm putting a 16x4 APC wide (which was on the Saito 100).
I had cooling problems with the Saito and kept taking the cowl off to open the bottom up just a little bit more before it started staying cool enough. I probably did a little overkill with the opening at the bottom of the cowl with the Evo. My understanding of the "rule of thumb" is have 3x the amount of opening for the air flow to exit the cowl than the amount of opening where the air flow enters the cowl. The opening for the muffler relief just didn't seem like enough since the muffler was blocking the way. Also, I didn't want to keep taking the cowl off to cut more if I didn't cut enough in the beginning. I learned that lesson with the Saito.
Here is a pic of the plane with the Saito:

RE: Evolution 100
I flew the Funtana 90s with the Evolution 1.00 today...
The Evo ran like a champ!
I had to balance the plane by moving the battery pack from the front of the fuse to just aft of the CG. No extra weight was needed.
I ran a full tank of fuel in the engine on the ground just to make sure it was reliable and to set the low and high speed needle valves...fueled up again and then I put her in the air.
I found the Evo 1.00 to be an excellent combination with the Funtana! It absolutely had more power than the Saito 100. I hovered at 60%-65% throttle. I was able to pull out vertical from a hover at full throttle with no problem, but it was slow getting started from 0 speed. The good news is that I was running the engine very much on the rich side at the top-end throttle position. I imagine that vertical ascent will be much improved when the engine is broken-in further, and I lean out the top end needle valve. It's hard to believe that there is more power to come!
I made 5 flights and I had no dead-sticks at all.
Because of the power of the Evo I found myself MUCH more comfortable with the Funtana overall. I was trying maneuvers with more authority. Much of that comfortable feeling was due to a terrific throttle response.
On a scale of 1-10 I would give the engine a 9 in the Funtana 90s. I'll report back periodically as I put more flights on her with the Evo.

RE: Evolution 100
Hey Pete!
I have not weighed the Funtana with the Evo. BUT I know that the Evolution 1.00 is about 8 ounces heavier than the Saito 100 (both with mufflers). I also know that my Funtana weighed 8 lbs, 11 oz with the Saito. I'll do the math (hopefully correctly) and just add 8 ounces to my Funtana/Saito combination and get about 9 lbs 3 oz for the all-up dry weight of my Funtana/Evo combination.
I used an APC 15x4 wide prop today and got much better vertical performance than when I used the APC 16x4 wide prop. The 15x4 gave me 10,350 RPM's at the top end (rich) setting. I'm going to try an APC 14x6 next weekend.
Hope this helps!
By the way - a flying buddy who owns a sign company made my Evolution graphics for my Funtana 90s. He used bright blue holographic vinyl. I put them on both sides of the fuse right behind the canopy.
I think they look sharp!

RE: Evolution 100
Thank you for the information Crashmaster. I am now building a AK Model Mig29 and will be using the Evo 1.0 and it should have a dry weight of 9.25 Lbs all up ( close to your weight). I was also thinking of using a Master Airscrew 14x6 K series.
If you have time please let me know what your vertical and over all performance was like with the 14x6 on your next weekend test flight
Pete
By the way GREAT looking aircraft you have there. ...... Like the BIG "E"

RE: Evolution 100
Great Info! I need to try the EVO 100 in my F90 as well. BTW, call Bisson for a Pitts style muffler for it. They should have one available very soon if not already.

RE: Evolution 100
Thanks for the information!
By the way...do you think it will it be quieter than the stock muffer (the stock muffler has got to be well over 95 db)?
I may just give Bisson a call...

RE: Evolution 100
I was flying my EVO100 + Funtana90 yesterday, and I kept getting deadsticks. The engine would be running fine for about 10 minutes, then I would hear a POP, almost like a backfire or the head hitting real hard. Then it would just die. Most of the time it was when I was just at a quarter throttle, and cruising, or coming out of a turn. Any idea what this could be? It happened 2 times in a row, but I could sit the airplane on a bench at the field and run it for 15 minutes at the same throttle without it happening...

RE: Evolution 100
Blade -
No information yet on the 14x6. I still have the 15x4 APC Wide on the nose and have been having an excellent time with it. I've got the RPM's on that up to 10,600 with terrific vertical. I think I'm STILL running rich.
I have 12 flights on the engine with no dead-sticks and no concerns.
I'll put the 14x6 up front this weekend and report back. Sorry I have not done so yet.
