Status: offline 		Well I'm part of the club now. I just got one of these plane in the original color scheme. I know a lot of people didn't care for the scheme but I actually like it. I think it looks really good in reality. Haven't seen it all put together yet so we'll see. I will be putting on OS 160 in it.

I have a question. Did you guys use the provided hinges on this plane? What kind of result and what kind of flying? I take it if you fly conservatively they are OK. But I don't know if they'll stand up to hard flying. They look so small they make me nervous.

Status: offline 		No problems with stock hinges here, and I've put them to the test. Those who see me fly know that I don't go easy on my 3D planes, and I've been thoroughly impressed with this airframe and its hardware. I only wish Ultra-Rc had survived...

Status: offline 		Well I wish I would've wait for your guys' feedback because I spent a whole day slotting for other hinges. The reason I did that is because on my EF Yak 74" they had the same hinges but the thicker ones and those developed slop on all surfaces. I imagined the little ones would be even worse.

I've read this thread up to page 83 and have 35 pages more to go. It took me a LOOOOOOOONG time. The posts I'm reading right now were made in 2006 and I'm dissapointed to see that 2 years later the issues on this airframe were not taken care of. It just seems that Ultra-RC did not really listen to their customers' feedback. With that said the airframe seems to be very good quality, the covering on mine was flawless.

I did notice that the outer tube of the landing gear has 2 small cracks along the length which appears to come from drilling the holes. Maybe that's why so many failed? It was just luck that I noticed it. I'm really looking forward to flying this plane. I will post flight reports and maybe video.

I agree, there is a wealth of knowledge in the thread and it does take a long time to read, but time well spent. I noticed when I checked your note there was an add for the plane at the top of the page! The plane is obviously back and in good supply. I think with as many issues as there have been on the gear and the number of folks who have carefully worked on trying to make it work that the cracks you found were probably not generic but just an issue with your kit. Otherwise, someone would have seen it before. I also agree with your evaluation of Ultra RC. The gear issue should have been addressed by now. Hopefully whoever is actually producing it for OMP will look into it and do a definative fix. I have a nice grass field to fly off but in the spring until we get it fully rolled down there are rough areas and any grass field can develope them. I chose to do the carbon fiber to plate mount option from the get go because of that. Haven't opened it up yet to do it. Will probably start the plane this weekend. Are you replacing your carbon fiber tubes then?

I think the cracks are more common because of the people that complained about those tubes splitting, the fact they are very hard to see, and they appear to come from when the holes were drilled. When I ordered mine from OMP they told me they just have a few left over and they are not producing them right now. I think if they fixed the issues on here (even if it comes a tad heavier) it could still be a good selling plane. I think it's more important to pilots to feel comfortable with their gear than to know they saved a couple of oz with the current gear. Most of them added stuff to it anyway.

As for right now I think I will just reinforce my carbon tubes with either one more tube inside or music wire + I would like to enforce the landing mount a bit as well. It just doesn't look strong enough. On the bottom of the fuse (where most of the force will be applied in a landing) it looks like there is only one layer of 1/16 ply to hold it from spreading or breaking backward. I have to review all the notes I took (a bunch) before I make my final decision.

Call the guys at OMP. One of the owners I think it is flies his with a YS 1.4 and had the flex out happen. He described to me a mod he did that solved it when I bought the plane at Toledo. But not being familiar with the structure I did not comprehend it well enough to be able to describe it. Would be worth getting on the thread.

I was a member of RCCD the last two years but just for control line flying. I fly RC with the Flyin Wolverines Club in Algonac, MI which is the mainland across from Harsens Island. I don't fly RC at RCCD. They only fly cirucular patterns. To fly true aerobatics I had to be so far away I could not hear my motor on a .40 size plane. Much less see anything for 3D. The Wolverine club is much smaller, about 35 members, totally noncompetative, and our field is actually bigger... like 2800 ft! Its a former private grass strip. We opened up about 850 ft of it to 250 ft wide, and mow 1200 ft of the original runway to carpet length. But if you need it for an engine out, there is the full 2800 ft that is cut usually to about 4 to 6 inches beyond what we cut. With that small a membership we can fly close in aerobatics of any kind we want. Additionally we have a tree line behind the east west flight line that has a row of trees about 75 to 100 ft high that blocks the strong southerly winds. So we can litterally have a calm runway when the winds are 25 to 30 knots out of the SW, which is our strong wind direction here. Its taken us 3 years to develope the site. We hope to get final finishing of the road with crushed stone in the next few weeks and it will be about as ideal as you could want. Right now we have a damp road issue that prevents access in the spring til it dries.

As to batteries, I have flown only 6 volt systems for about 4 years now. Bigger servos take alot of juice. I fly my .72 to .90 size 3D planes on 1400 mah nimh batteries. But I have found the need to recharge after 4 or 5 flights on that size servos (120 oz rudder being the largest). The large digital servos I'm going to use on the giles have me planning on about 22 to 2400 mah nimh. I am running 4 stroke glo so I don't need an ignition battery. I know some have used smaller. But I don't think I've heard anyone going under 1400 mah.

... would love to be able to go and get in 4 good 15min flights w/ the giles w/o worring about the battery, so what do you guys recommend

Batteries of 2400 to 2800 mAh capacity should get the job done.

If you're interested in trying the newer battery technologies you can take a look at the Troy Built website http://troybuiltmodels.com/newsite/planeacc/batteries/li-ion/2cell.html.

Li-Ion battery $41.50:
TBM 2-cell 2400 mAh, 7.4v Li-Ion battery. Weight 3.5 oz, Dimensions 0.8" x 1.5" x 2.6"

Regulator (required) $19.95:
MPI 6v voltage regulator. Weight 0.6oz.

When I bought a TBM 2-cell 2800 mAh Li-ion battery from them it was only $26.95 (pictured below with regulator). Now it appears that they may be pushing the Nano-phosphate lithium-ion technology.

Nano-phosphate lithium-ion battery $28.95:
TBM 2-cell 2400mAh, 6.6v Nano-phosphate lithium-ion battery. Weight: 6.5oz, Dimensions: 2.34" x 2" x 1". Heavier than Li-ion & regulator.

Regulator: (none). People are using them without regulators.

Sorry it took me so long to get therse pictures, just my wife had different plans for me. Anyway here is what I did for installing the Graph Tech gear.

I added an additional plywood plate so the Graph Tech Gear would not hit the tubes that extend out of the bottom of the fuselage. I use two (2) 1/4 x 20 nylon bolts. This gear holds up a lot better on our rougher grass strip. The only down side is the extra weight, buthonestly I don't notice the weight difference. Sure beats taxing out and breaking a gear tube.

Hope this helps,

Jim
