Progress update after the holidays. The wing and stab are mounted and the surfaces hinged. The belly pan pipe tunnel and pipe mount are completed but not sealed yet. The engine and Ice Point gear are mounted. The Ice Point gear gives lots of clearance with a 17" prop installed. The rear pipe mount is screwed and epoxied to the wing hold down doubler so that it can be removed when the wing is taken off. I imagine I will use an o-ring hold down ala AeroBob.:) Thats it so far.

RE: Excelleron 90
Thanks Bob.
Also i see that you have a presure fitting on the canister muffler.Did you do this your self or did it come like that? |
RE: Excelleron 90
DOes anyone have an idea about down and right thrist for this beast. After having to adjust the horizontal stab and wing by quite a bit I really don't trust just lining the spinner up.

RE: Excelleron 90
I did the pressure tap. A little tricky, but use a 90 deg on a short piece of fuel line to get it pointing forward, and it's fine.
olddogg60 - coupler material looks familiar:D. Great job with the Icepoint gear. I have them, and may install if I need the clearance...also have an Icepoint PLANE coming, too....should be a fun Spring!! Haven't flown the thing....still too dang cold/windy/freezing for me...but I will !!!! I did set the thrust by just the spinner ring against the face of the fuse nose, and it was okay. Maybe needs a skosh more right thrust, but I don't know for sure. |

(See previous.:D) I did glass the pipe tunnel and mount today. I think that I will give them a shot of white paint to dress them up a bit then start mounting linkages and servos. |

PETEC:
My Excelleron is powered by a ys 110 and with the stock amount of right thrust I still had climbing issues. after adding about 3 degrees more it worked out perfect. if you are using the st 2300 you will likley need to add a little more. Hope this helps. Dan |
RE: Excelleron 90
gabrielg74 - BEAUTIFUL field, and great looking Exc. LOVE the canopy, good color choice. On your trim issues, you may want to verify that the thrust is correct. You could have some downthrust in there, assuming they got the incidences right on the stab/wing. Hopefully, the ply crutch of the motor mount can be used as a datum reference for longitudinal axis, but I have no clue.
What are the deflections (in degrees) you're using on elev/ailerons? On my webpage under "hints" are some ideas for making deflection gauges cheaply, and there's also a trimming chart you may want to check out... it's pretty good. [link=http://www.rcaerobats.net]Aerobob's RC Website[/link] |

Although with the stock mount right thrust would be an easy issue to change...... Thanks guys. Pete |
RE: Excelleron 90
I just ordered one. They are on sale for $229-not bad considering the 50 is $10 more right now. I have over 10 years flying experience, but haven't been flying for the past 2 1/2 years. I was going to get back into it with the Funtana 90 (I already bought it, a 1.10, hi-torque digital minis, and other radio gear) until I flew my 3D foamy and realized that I have practically forgotten how to fly, so I figured I'd better get back to basics...point rolls, square loop variations, snaps, etc. This plane looks like a good place to start.
Anyway, on to my question: Does anyone use this plane for other than "Pattern" porposes? I have a deep appreciation for precision flying, but using every tank of fuel to practice a pattern all year long that someone drew up in the back of a magazine is unorigional and boring, to me. So I am wondering how well this plane "freestyles". Not 3D, necessarily (I have the Funtana for that), but the occasional torque rolls, flat spins, tumbles, and various Knife-edge maneuvers...any input? |
RE: Excelleron 90
I have an Excelleron in the building queue myself. My flying situation resembles yours as well, having flown (at) pattern for a couple or three years about 15 years ago, but having also put R/C aside completely due to partial loss of use of my hands from arthritis until just a couple years ago. I resumed flying on a limited basis by becoming interested in electrics (easier to start the motors), but never lost the love for the aesthetic and handling appeal of pure pattern birds. I've been flying only sporadically the last year or so, but haven't flown anything glow since about 1992. [X(]
Anyway, I will likely be flying my Excelleron much more for sport than competition, like you. There is no shame in NOT flying pattern with a pattern aircraft, is there? :) I just have always liked the locked-in feel and responsiveness of one over 95% of the sport types out there. I'm sure the guys (MTK) at the local field will be trying to nudge me back into pattern flying, however, when I do get it flying. We'll see how that goes. Heck, I don't even know what the Sportsman pattern looks like any more. I did catch myself doing stall turns, point rolls and slow rolls on Aerofly Pro the other day with the Smaragd though...:) Good luck with yours. Rick |
RE: Excelleron 90
bodyworks,
I'm in the process of finishing mine. I bought this plane for the purpose you and ElectRick mentioned, but I did opt for the high, high priced digital precision servos....just in case. I don't think it will be a problem, this plane has big control surfaces. I recall Bob P. setting up his rates at 14%/15% for pattern flying. If memory serves me well (from reading all the threads), this plane is a re-badged JR Explorer (acrobatic version). Of course, it really does not matter, we all know skill is what makes the difference here. If you want to see a pattern ship this size freestyling, look for the Widebody 60 video in this forum (I think its on p.3 now). |

Rick I hope I haven't offended anyone with my previous post. I have full respect for precision aerobatics, but I prefer to fly them with a sense of freestyle and a little extreme-type flying thrown in. |

RE: Excelleron 90
I think I'd better clarify - I have my TRAVELS set at 14 *degrees UP, and 15 *degrees down on Elev. about the same on Aileron. Definitely NOT 3D, but I'm a 2D flier, so it's okay.

Well, tomorrow should be the first flight, as long as the wind stays down. My Excelleron has the Icepoint gear and canopy. I painted the canopy black because I like how it looks. I used 1/2" 3M white electrical tape (cheap stuff from Pep Boys) for trim and to hold it down, plus I added 4 screws for good measure. I also used a Sullivan tail wheel.
The engine is a TT 120RP with header and pipe, the same as olddogg60. I copied aerobob's cut out of the belly pan. I used a Sullivan 24 oz. tank and moved it to the front of the wing area. The plane balanced exactly at 7.25". We'll see how tomorrow goes, I still may have to play with the prop size/header length to get it to run right with the pipe. There's not alot of header length to play with. I'll be starting off with ACP 16x6 and 16x8 props and go from there. |
RE: Excelleron 90
Ric,
Looks good. Don't be nervous about that first flight. You're going to find out it's one of the smoothest , easiest to fly airplanes around. Good luck, tommy s |
RE: Excelleron 90
Hi Ric,
Your Excelleron looks great. I'll certainly be waiting to see how your flight goes with the TT 120RP.:) I have been taking my time with mine. I have finished the pipe mount and belly pan and cut out and mounted the cowl today. Best of luck on the maiden flight. |
RE: Excelleron 90
Yee HA, Ric.... 24 ounces!!!! Holy COW, man....I'm glad we don't share frequencies:)
Yours looks REALLY great...the canopy and gear just set it off beautifully! We want a full report, when you're able to type....best of luck to you! |
RE: Excelleron 90
Tommys - guess who has a YS 110 on the way for Excelleron #2 ????
Yes, it is true.... But I will build/assemble that as a "sell"project.... If anyone is interested in a NIB Excelleron, and a great condition YS110 to go with her, let me know!!! |
RE: Excelleron 90
Bob,
This must be a typo !!! A four stroke ? You're going to like it so much you'll probably sell #1 . Let us know , and be objective , the 1.10s are easy to live with. tommy s |
RE: Excelleron 90
the black canopy looks excellent. I take it you painted the INSIDE of the canopy?
what sort of paint can be used on that plastic which is also fuelproof... do i need to treat the plastic with some special primer first? mike |
RE: Excelleron 90
Hay Mike you dont have a Lark do you?
|
RE: Excelleron 90
what is a LARK??

RE: Excelleron 90
Well it flew today! Talk about an almost perfect plane! I had several people ask me about the plane and engine. It has very impressive performance with the TT 120RP in it. It made me look better than I am.
OLDDOGG60, you're going to love this combination. I don't have the engine tuned for max performance and I'm only running an APC 16x6 but it is turning 10,800 rpm and is plenty fast. I can take off and point it straight up and it will go forever. Very cool. Mike, BODYWORKS is right, I used the RC Racing Finish paint. It's actually flat black but since I painted the inside of the canopy, you can't tell. AEROBOB, you have to be insane to put that much power in this plane:). What am I talking about, there's no such thing as too much power. When my friend wants his TT back, I'll join the Insane Brigade and put my ST2300 in the plane. One of the guys commented that I probably didn't have enough power yet because the covering was still on the plane but he was surprised that it was! This plane does it all VERY well. Knike edge required just a touch of down elevator and spins and snaps are great. It also lands very nicely. I guess this plane is just about as close to perfect as you can get. I should have bought 2! |
