Finally getting the Evolution put together, and it was a very stright forward build. Next is to find a good day to test fly the plane.
Here are couple pics. |
RE: Ultra Rc Evolution
any pics of how the engine is mounted?

RE: Ultra Rc Evolution
It's a soft plastic CA applicator. Makes it much easier to control the flow of thin CA on to the sheeting than using the CA bottle.
ORIGINAL: jlkonn Eric, What is that device in the first pix to the left? Looks like a little squeeze bulb or something. JLK |

Fitted the tailwheel tonight. Used half of a stick-hinge as a retainer for the tiller arm.
Engine tomorrow if it rains ..... Eric. |

The engine mount was very easy to do. There is a template included in the ARF kit. Also there is a hole already in the firewall that was the center of the Hydemount. A long drywall-screw was used to temporarily hold the mount and engine in place.
A 1/4” lite-ply brace was fitted between the firewall and the former that touches the canopy/deck. I used a former like this in the Quest and it did the job! Apart from providing support to the firewall above the firebox, it also holds the second former in place and sets the angle that it meets the canopy. Regards, Eric. |

To make the canopy easier to use the front two locating tabs were cut to help the canopy drop into place.
The instructions say that you should make sure that the 3-mm cowl bolts and blind-nuts go into some ply. This was a bit easier said than done. You have to carefully locate the available ply and then transfer that position onto the cowl. Regards, Eric |
RE: Ultra Rc Evolution
The Cowl is a tight fit on the front. To improve this situation I removed approx 1/32” from the top edge of the canopy former. This former is covered by the cowl and can be touched-up with a red marker-pen if you can still see some wood. The cowl fitted up nicely against the canopy/deck and gave a good separation line all of the way around the top. I used a ply spacer to adjust the gap between the cowl and the spinner plate. |

Nice join line with canopy.

Shoot Eric!!!!!!!!!!
You're making me wish I got one of these!!! JLK |

The cowl uses neoprene grommets that fit into 4-mm holes. Fit these grommets first and then drill into the fuselage sides, for a more accurate cowl fitting. I substituted the 3-mm bolts and blind-nuts for 4-40’s. This was because if you lose a cowl-bolt at the field it is easier to “borrow” or find a 4-40 in your field box.
Next step is to fit the wrap-around header from Karl Mueller. The 2" drop (Temepation/Impact/Pinnacle) version lines up pretty well. An ES CF medium length 1.40 2-c pipe also goes into the tunnel just fine. No building today - rain tomorow though :) Regards, Eric. |

I forgot to mention that the hardware that comes withe ARF is virtually the same as what comes with the Giles 202. There is a set of useful servo arm extensions that work well on the rudder and elevator servo arms.
The rudder will be driven by an 8611 and was pretty simple to hook up. The slots for the pull-pull wires lined up just fine. I used ball-bearing horns and servo-arm-clevises as a personal choice to get a rudder that centers as good as the servo centers. Tomorrow the tuned pipe will be installed. ;) Getting close... Eric |
RE: Ultra Rc Evolution
has someone flew the plane? Some characteristic of flight?
i am really interested in the plane , please helpme with that. Sergio. |

Please give your opinion of the composite servo arms. They seem easy to flex. Sort of like they could use 4 screws to attach them to the standard servo arm. Did you use these on the giles? Thanks! Chris |
RE: Ultra Rc Evolution
I used them on my rudder etc. and have seen them in use on 3-D version of the Giles 202.
There is a pilot out there, Tumbler is his name, who takes the controls and maneuvers to the far ends of human capability. His seem to work just fine. The reason that I did not use the ball-connectors on the rudder is because the wire and hence the ball joint is under tension all of the time. This is not how I would configure for the forces of pull-pull. The more the wire is in-line with the rudder horn the better. On a control like an aileron, which is push and pull, both the horn and the servo arm extensions seem to be able to handle the loads. I did two G202's like that and they are still holding up well. Of course many pattern pilots replace all of the hardware in many ARF pattern planes because they have developed their own systems and preferences. Regards, Eric.

RE: Ultra Rc Evolution
Thanks for the excellent explanation!!!
Did you have a thread for the giles. I'm sorta interested in it. Although after this arf, I think I will stick to building my own from now on. On another note. I was told by Bryan that he had an issue or two with people replacing the control horns and other hardware, and having flutter. I noticed you did this. He said the surfaces were set up for his hardware and he couldn't warranty the plane if you changed from his hardware. Just thought I would mention this. I changed some of my hardware also. Although, my plane hangs on the wall still. Awaiting Bryan's call to replace the wings amongst other parts.. Chris |

Probably the hardest thing to do is fit the landing gear wheel pants. The Carbon Fiber stick legs are pretty easy to install especially if you use a tool to hold the axles in line with each other.
Pictures are from the Giles 202 build but they give you the idea. Regards, Eric. |

The wheel pants on the Giles are still working. Here is what I used this time as well.
This uses a Sullivan wheel pant bracket. The side arms were tapped for 2-56 threaded bolts which were CA'd in place later. |
RE: Ultra Rc Evolution

The Sullivan bracket uses a 4-40 bolt to clamp the wheel pants to the axle once the pants are lined up.
JB-Weld was then used to fill the gap btween the leg and the pant for a tougher hold. Hope this helped make ths task a bit easier to perform. Regards, Eric. |
RE: Ultra Rc Evolution
Eric,
Is that the "firm idle" mount? If so, does the engine move around at least a minimum amount? |
RE: Ultra Rc Evolution
I hear ELAN120 will FINALLY be at this weekend's pattern contest in San Jose, CA. Yes, Kevin will be there, I spoke with him today. He'll be flying Evolution and I'll be honored to help him in his first contest. Can't wait to see it fly.

RE: Ultra Rc Evolution
I'll have mine there. Unfortunately it won't be flying. Just to show you the issues.
Well. That's if I can get two ships in the 4 runner.. C |
RE: Ultra Rc Evolution
I have both the "A" and the newer "C" mounts. They both do not use a nose ring. I used the "A" because my "C" had been custom drilled, by Merle Hyde, for a shorter installation.
As regards movement. The two mounts above, have more or harder rubber and hence the engine does not move much. I have remote mounted the needle on the firewall so the only clearance that I have to worry about is where the header protrudes. (Pictures later). I leave approx 1/4" clearance. The engine does not move nuch at all during normal running, but if you go to "silly' idle speeds it will bounce around as the engine kicks as it almost tries to run backwards. The "A" mount is not what I would call a soft-mount even though it does work a lot that way. I see it more as an iso-mount. It takes the vibrations away from the airframe but cannot absorb all of the engine movement. Vibration and "kick" absorbtion are two different problems to solve. I like what the "A" does on my planes with the YS 1.40, the OS 1.40 and the 1.60. If I was running a YS 1.60 DZ I would use a soft mount with a nose-ring due to the starting kick issue. Sorry about the long answer but the iso-mount/softmount term does cause a lot of confusion out there. Regards, Eric. ORIGINAL: Aresti-RCt Eric, Is that the "firm idle" mount?

Here are some pictures of the cowl clearances with the Hyde "A" mount. Also the OS 1.60 header and pipe support.
The Karl Mueller side-wrap-around header will not fit inside the cowl and I have become accustomed to it as my "Harley" look! ORIGINAL: Eric.Henderson I have both the "A" and the newer "C" mounts.

A lot of what I am doing is based upon what I have read in this thread and in the Giles thread.
One area that I thought I would "try something" is the canopy/deck. The canopy is molded as a deck as well. It is pre-painted red on the outside and the rest is clear. I sprayed it silver on the inside in an attempt to perhaps reflect the sun's heat. Time will tell on that one. BTW - It is not actually just silver. There is a blue speckle to make it look a little less metalic. Regards, Eric. |
