ORIGINAL: aerobob Yep. Elevators when the crappy CA hinges started failing/splitting. Clearly audible. Fixed by replacing with DuBro flat pinned hinges installed with Zap "Hinge Glue". |
RE: Great planes ultimate 160
IF you have to remove the old CA crap hinges..... I resisted at first, but "Ultimately" gave in ;) ... and bought the Great Planes Hinge SLotting tool with the "Heavy Duty" blades. THAT tool made the job nearly painless....the saw is very fast, cuts very accurately, and doesn't damage adjacent wood (or hands/fingers), and creates a PERFECT slot for the flat DuBro Heavy Duty hinges.
It's one of those tools you won't buy until you need it, probably, but man when I used it I *knew*.... it is worth TWICE the price in PITA-savings :D I just wish I had my Brillelli 46 mounted up, so I could go enjoy this wonderful pre-fall wx.... but maybe NEXT weekend.... |
RE: Great planes ultimate 160
A scroll saw, coping saw, or jigsaw blade cut sown and installed in an Xacto knife handle works, too.

RE: Great planes ultimate 160
anyone here have 2 rudder servos installed? i am debating whether to go with 2x5645s (I have a couple extra) or 1x5955 (I would borrow this from anothe plane I am assembling). I figured the extra weight of the 2nd servo would be good on the tail... :)
|
RE: Great planes ultimate 160
I just have one 5945 on the rudder, and it is plenty of power for knife edge loops. This plane has lots of rudder authority.
|
RE: Great planes ultimate 160
So for those who has mixed the coupling out, what is the roll and pitch coupling mixes that you use?
|
RE: Great planes ultimate 160
do you think having another 5645 on the rudder would help in any way?
|
RE: Great planes ultimate 160
To me, simpler is better. I have a 5955TG on the rudder, and that's about as simple and as powerful as you can get, plus it doesn't have any extra linkages to hookup, wires to run, or components to fail. This isn't a bird that seems to need you to add any weight to it. That's a big fuse, and if you are nose heavy, then move your batteries back. I mounted my 2 2400 Fromeco packs for the RX just behind the cockpit on a tray I made tying it to a existing former, and the CG is pretty much dead center. I'm still trying to find the exact spot I should put it in, so I'm using stick ons until I find the best location flying wise, then I'll move the packs farther back to match the CG without any additional weights.

RE: Great planes ultimate 160
ncrego, can you post a pic of your battery setup? i am trying to get ideas on how to best mount my fromecos... i lost the last plane because the battery tray broke during a snap.
thanks! |
RE: Great planes ultimate 160
A 5645 might not be enough alone... and twin ruddder servos have been done... but direct push-pull with two servos need to have special attention to matching performed or they may fight throughout the travel.
The cost of two 5645's i about the same as a 5955... and the latter will weigh less, provide less lash in the gear, one less failure point, easier setup and perform excellent. If I had two 5645's I'd sell them to buy a 5955... just for these reasons... |
RE: Great planes ultimate 160
I think 1 x 5645 is probably enough for a 15 lb plane. However, having said that, 5955 is just so much better.
|
RE: Great planes ultimate 160
I have 5955 on rudder and 5645 on elevators.
Elevators are sloppy already. Rudder is still tight as day one. Wish they would make Titanium the standard for all metal gears.:D Wishfull thinking huh? Then sales would drop. |

RE: Great planes ultimate 160
I guess my Ulty does not want me to fly it.
Put new 645's on the ail. Sitting there working them and they sometimes over rotate, lock, then release. With only 3 pluged in it is fine. Thought maybe it was a y so I started switching them around. No matter where they are plugged 3 is fine and 4 is too much. Any ideas? Then I thought while it was all together I would run it since it has not run for over a month. Fired her up and let it warm at a high idle. When I tried to advance the throttle it sounded like a v8 running on 2 cylinders. Started playing with the needles but no change. Screwed them in and back out to last known good setting. fired up and sounded good. Went to full thr. and it ran great long enough for me to grab the tach next to me and see it run at 7000- then it just quit. Pulled the plug and grounded it against the engine. Turn the switch on and it sparks. Went through CH's guide and it says the pulse switch. Tried 2 others that were good (unless they went bad sitting in the box) but still no spark. Guess I will send the ign and pulse switch to CH and see what they say. |
RE: Great planes ultimate 160
Are you trying to run all 4 servos into one receiver port via 3 y-harnesses? If so, that's your problem. You need a minimum of 2 ports or a signal amplifier most likely.
|
RE: Great planes ultimate 160
Guys, I just got one of these beauties for my birthday from my better half :D It replaces my world Models 27% Ultimate that met an untimely demise when the receiver or switch quit working (damage from crash was so extensive I can't tell exactly what quit working).
Anyways, not wanting read thru 111 pages on this thread can anyone summarize the consensus for mods/improvements on the plane. I've already noted substituting CA hinges for flat pinned hinges and after looking at the fuse, I'll move the tank to behind the firewall since I'll be using a Moki. |
RE: Great planes ultimate 160
I built mine stock except for pinned hinges in the elevators after reading the whole thread. Now that it has some flights on it, I've observed that while the tailwheel arrangement is awesome, the wheel/tire itself is a joke. Replace it from day 1, it won't even last through the first day if it's like mine. Other than that, I'm planning on putting plugs for the upper ailerons in the top of the fuse with the ernst connectors like they show in the manual, and that's about it. I'm contemplating another gear arrangement, as with a 23 inch prop like I'm swinging, the ground clearance is minimal (less than an inch with it at a level takeoff attitude, but a Moki won't swing that big of a prop, so it shouldn't be an issue for you.
What are the rest of you guys running DA50s thinking about the gear? I don't mind the flexing, but if I ever have a less than soft touchdown, I'm betting it'll prop strike. |
RE: Great planes ultimate 160
Nope. Ch. 1&6 on a 138DP
|
RE: Great planes ultimate 160
go with either 22x8 or 3 bladed 21x8.
|
RE: Great planes ultimate 160
Thanks ncrego - have noted tail wheel. Prefer metal hubbed units anyway (so I can solder the washer on).

RE: Great planes ultimate 160
I got dropped off this thread a while back and I was wondering what was the heaviest weight that this plane came out at and how did it fly?

Jim I feel your pain Jim. When you go bigger, everything is just more expensive. That's one flight that caused you at least 25 dollars. |
