So far I read 5 pages of the 144, I guest it will take me a few days to read all the comments, I'm mainly looking for any changes that I should implement before I give her the maident flight, so far I read that the landing gear needs to be reinforce some how, I already have an idea how to do that ( I think ) [&:]

Anything alse that I should be aware of?

CARSII - there's a bit of a list that people here have developed for reinforcing the 70" Revolver - you might want to keep reading these pages for details. My quick list - replace main and rear gears with Dubro's, reinforce the floor for both gear, use Robart Hinges, add cornering to renforce outside corners of the engine box, use 4-40 pushrods and hardware, some install twin elevator servos in the tail, re-epoxy in the main wing engine boxes (they sometimes pull out in flight). I'm sure there are other's I'm forgetting.

Microdon2-

Don't you mean the aileron servo boxes, didn't know the Revo 70 was a twin.LOL

and after all this, what you saved just went down the tubes...

Woke up early, for me anyway, and was at the airfield by 8 this morning. There was maybe 1-2 mph wind gusts, completely blue skies, and only mid-seventies. I think this was just about the most perfect flying day I have had in the 3 yrs I've been doing this. I flew the R70 and the 3DHS Edge 540 this morning. The Edge 540 will now knife edge with only rudder\throttle inputs...no hands on the second stick! I don't think I've done any mixing on the R70 yet. Now that I've seen what it has done to the Edge 540, I'll start on the R70 soon. Anyone have any experience with AW Extra 300 or Extra 260? They have .60-.90 versions of these planes the hover, barely, with a 60.

Had good and bad happen today, the bad the revolver's elev ca hinges brokeon one side bring it down in the farmers field, luckly i was able to belly it in without any damage. Now if I can figure out how to get ALL the ca hinges out and replace with robart hinges. Now for the good my son whos 11 yrs old was able to do his first landing today on his forth flight, it looks like he may be taking over my planes soon......lol

ifly - I never claimed that these reinforcements would save you from pilot error! HA! But they certainly make for a stronger, more reliable airplane. And I DO crash occasionally, sometimes because I like to push my flying envelope, and other times because of my own dumb mistakes.

In the news this morning - Bryan Jensen - renowned pilot of the Horizon Hobby "The Beast" crashed and died at an airshow in Kansas City. From everything I've seen and read he was an excellent stunt pilot. He had over 23,000 hours of professional and stunt flying. If THIS guy can crash it can happen to anyone.

I am very saddened to hear of this news about Bryan. I read about it in the local newspaper this morning. I met Bryan a couple years ago at an event...he will surely and sorely be missed. My condolences to his family.
From what I can gather, he was in a spin....whether a "nosedown" or "flat"...I don't know.

Hello mudboger07,

Taking off the CA hinges easy and fast,....all you need is an exacto knife and just slice the ca hinges off. Now you can use the same exacto knife to very,...very,..very,....patiently cut out the rest of the left over hinges inside the tail. This is a very slow hof and requires a lot of patience....Or,..if you can just leave them in there and put your robart hinges just under or over where the CA hinges were,..this way you don't have to go through the long trouble of taking the left over hinges out. In the past I have left the left over hinges in and placed the reobart hinges just over or under the old ca hinges and it has worked fine for me. Good luck,...

Anyone has one of these equipped with a 75AX?
I have a 75 from  crashed plane and I can't wait to have a new plane.
The Revolver 70 is high on my list but although it calls for a 60 to 75, everyone here seem to suggest a bigger engine.
I am curious to know if anyone has one with a 75.

Thanks,

Harry

mudbogger07 \ flyboy0608 - For Robart hinges on the Rev 70 I cut the CA hinge and trim down to the surface, and then install 5 Robarts in locations other than where the CA hinges are still glued-in.

Thats kinda what i was thinking about doing, but i wasnt sure if there was enough wood to support the hinges in different locations? If there is that is what i'll prob do, if not I'll remove the ca hinges and replace with robart, now that i think of it I have a broken elev half I can looka t to see if there is enough wood for support.

I think there is enough - none of my Robarts has ever come loose. One tip - after drilling the hole (I actually use a small screwdriver - more accurate for me) - I use a pushrod to get the 30 min epoxy into the hole before inserting the hinge. Then, when all the hinges are glued and inserted, stand the wing up with the leading edge pointing up, so that the glue that's still liquid might slide down the hinge and form a plug against the wall. And, of course, use vasoline or oil on the hinge pivot itself, to keep the glue out.

Thank you for all the tips, I'm sure I will be using some if not all.

micro
i c you on the top flite p-51d arf blog hurry home honey go to that blog an make a comment so i can get on it from my e mail shold i lighten up my bird

I'll give that a try, I also noticed this was not all that brought it down, upon looking at the rx, when i turned it on it would would work but the light were blinking, none of my other rx's do this the light is just on on them so im guessing i have a rx going bad. If so this is the first one thats done this. and ya its a spectrom rx but i have had great luck with them, i'll either send it in for repair or just get a new one.

microdon2,

Maybe i didn't explain it correctly but that is exactly what I was trying to say. I also trim them to the very edge and install the robart hinges where there were no ca hinges.....thanks for clarifying that for me,.....

flyboy - I did try to dig out \ drill through the existing CA hinges but it was too difficult to keep a straight line. Now I just do the Robarts from scratch (when it's a new wing). MUCH easier.

Got my Sanyo eneloop batteries in for the Revolver 70 and only took two days from order.. Fast
Newest version 2000 mah and 1500 charge cyles... as advertised they come charged.
Nice working with Thomas Dist. Don't go through Google or Amazon go direct for free shipping. Now for some servo hardware from a really super sale here:

http://www.servocity.com/html/web_specials.html
You know extra eyelets, grommets and extension leads and so on check out the prices.
I don't know if the extension plugs have gold plated pins or not if that is important to you.

Having Fun Now on the Rev. 70 building battery packs for TXs and RXs !

Have Fun Guys

Here is a tip on how to, make new holes or remove a broken robart hinge, get your torch, a piano wire or screw driver smaller than the hinge then burn throug the broken hinge, what your looking for is to melt it down.

The building of my revolver has started, here are some pics of my solution to the landing gear weakness, simple, clean, light, easy, the best part. I got the idea after viewing the pictures from jet22b of his broken gear mount, there I was able to see the mount plate shape and the gluing points, I have done this before ( picture ).

You guys that are trying for a good and easy way to remove ca hinges...simply use a thin cutting wheel on a Dremel and cut right into the hinge. It will remove the material usually in one cut. If you choose to go with Robarts, then use Gorilla glue instead of epoxy for a better bond. Just make sure you wet the balsa before gluing.

+1 on Gorilla glue
I used to use 30 min epoxy for hinges, and still think that is fine. Gorilla expands to fill any voids, which is an advantage. BE SPARING WITH IT. A little goes a very long way.

I entered this forum with post #657 on pg 27 and to make a long story short I got a bit side tracked in Afgahnistan and other things so I am just now getting back to finishing the assembly of my Revolver 70. Pictures on the top of page 30 Back then I think I was the first, here anyway, putting a GAS engine on this plane. After some review of the thread I see it is becomming a common practice with the DLE 30 I think being the engine of choice. How are they flying and what kind of weight are they flying at? I hope to get mine finished here in the next week or so. It's good to be back at it.

Mr67Stang - Welcome back! And thanks for your service. For engines, actually, I believe it's the DLE20 that has become the engine of choice. There is one guy who's published installing the DLE 30, but I think he's the only one so far. Personally, I think the DLE 20 is the perfect engine for this plane. It's got speed and power and just fits. I also have the DLE 30, but in a 73" Sukhoi 26m - a much larger fuse, too. I think the DLE 30 is the perfect engine for a 3D plane of that size. Either way, I look forward to hearing and seeing more of your build and flying.
