They aren't growling much with the throw, its the growling at neutral that I dont understand. Once I tap on the elevator lightly (up or down depending on which way they were last operated) it stops.

During max throw, the servo arm is being twisted slightly. So I'm kinda worried that it could either prematurely wear the servo shaft, bearings or gears or cause the ball link screw to loosen. It's hard to see in the photos I posted, but it is getting twisted for sure. So there is some torsional stress being put on the servo arm...

Look up a local Amsoil dealer and Im sure he could get some for you for cheap or maybe for free. I know a guy who is a dealer. He was going to give them to me for free since its free advertising but it was only 5 bucks, so I paid him for them.

If you cant find anyone near you and you really want some let me know. I can get them and ship them to you.

Re: the twisting? Is this because the servo has more throw than the control surface? In other words, no twisting until the control surface has moved as far as it can? If so, sounds like you need to get into your end point adjustments, or move the control rod in on the servo arm. Or am I still not following? -Al

Re: the Amsoil stickers. One of those comes in every case of Amsoil. We used to go through several cases a season when snowmobiling, so even after putting them on the sleds, over the years I had a stack of those things that I threw away a year or so ago. See a local dirt bike/snowmobile dealer to see if they might have any laying around they'd like to sell.

Hey Al, I honestly didn't think it was due to the elevator hitting its max throw. It very well could be. I've been so busy that I haven't had time to look at that. I'll probably just pull some throw out by adjusting my end points. It should be fine and I doubt I'll need all that throw anyway. It's not a real 3d plane...

It seems like activity has died on here the last few weeks (I know it goes in waves on here). Do all the active members in here have dead Revolvers?

I went to mount my cowl the other day and realized I screwed up. I mounted my engine where the thrust washer is at 6"from the firewall. That was the distance needed for my Edge 540 (I'm a dummy). So I've either got to redrill the holes on the mounts, or I can use my old motor mounts from on of my old Revolvers. Just one more step I've got before I can fly her. This is taking me forever! I've just been to stinking busy! I want to get her in the air so I can have some fun, AND I want to move on to my 50cc Extra...

After about 50 flights and a few bad landing I managed to crack one of my fiberglass land gear legs. I had carried out the landing gear mod using an aluminium angle to tie the landing gear block to the firewall and this did its job no damage to the land gear block at all.

I have made a replacement landing gear leg out of 0.100" 2024 aluminium I have it angled back to keep the wheels in the same spot as the original. I made two landing gear assemblies one thicker at the base this is the one that I decided to install as I think it has the right flex for the job. After two sets of wheels pants I have now decided to leave them off.

I also have Revolver number 2 ready to be built once number one bites the dust. Number two will have dual rear elevator servos and pull-pull rudder. After a lot of practice I have managed to get the revolver to do upright flat spin I just wasn't using enough power in my initial attempts.

Knock on wood, my Revolver is just great. Maybe that's the "problem"? But i am very happy to have this problem. As soon as the dreaded white stuff arrives, i plan on re-hinging the entire plane with Robart pin hinges. Just to give me something (else) to work on, besides adding retracts to Brian Taylor Spitfire, finish wing for TopFlite Top Dawg, re-skin Omega glider wings, add flaps and new retracts to Dynam Spitfire, build Hangar9 30cc Spitfire.....i am sure i am forgetting stuff. But until then, i want to fly the revolver much more.

Nice job on the LG superduke1. As my Revolver was used as i bought it, it was missing the wheel pants. At first i was going to get a replacement set, but with our groomed but less than perfect grass field, wheels only works just fine. Don't miss then at all.

Nice landing gear duke. I like that you swept them back. Looks a lot better than the straight dubro gear others have switched to. Are you going to paint them white? I understand ditching the pants if you fly on grass, but with the sleek look of the revolver, naked wheels stick out like a sore thumb (in my opinion). Lucky for me, I fly off of a paved runway.

Teckbot, the H9 Spit is really cool. What motor are you gonna be using?

Hello, has anyone placed a DLE 55ra in the Revolver? Is it a better choice over the DLE55? Many thanks for your help and advice. Chic

WOW.......a DLE 55 rear exhaust in the 70" Revolver ! That would certainly be a rocket ship for sure.

I believe you should be looking for the big red Revolver thread..........it's an 85" Revolver I believe.

This is an old thread, so there are occasional members who drop in thinking it's the newer 50cc planes thread. It does read "large revolver". I'm sure there is a thread for the big one, but I've never seen it. I'm not a fan.

I'm sure someone has used the 55ra in the big plane. I think I've seen YouTube videos with it. It's basically the same engine with the exhaust port moved to the rear.

Thanks guys, I have received a great response from an 55RA install. Its only 100 additional rpms. Never knew there was an 85" version. Not for me. I just want to fly IMAC Basic with something different. I am a scale modeler and I believe that flying IMAC will make you a better pilot. Not wanting to move up the IMAC skill level. Just want to be a more precise pilot. Chic

HI, Has anyone used the exhaust silencer pictured below on their DLE 20 or 20RA. Just looking to see if they are effective in reducing the noise without to much reduction in performance.

Can you give a little more info on what you're doing exactly? Are you installing a DLE 55ra on a 70" Revolver? And you got 100 more rpm over what, a standard DLE 55?

A DLE 20 is a bit overkill for the Rev 70", so a 55 shouldn't even be a consideration. It's WAY too heavy for this plane (both wing loading and CG). If it does fly, it won't fly well, and you'd need a Texas mile and a ton of airspeed to get it back on the ground. Not to mention the airframe and engine box being quickly destroyed by the weight, power/torque and vibration of such a huge engine. And the prop? There isn't enough ground clearance for a prop that would be used on a 55cc engine...

With that said (I'm going to assume I misunderstood you about putting a DLE 55 on the 70), from my experience with this plane and hearing from guys who have flown IMAC , the Revolver would be a good plane for IMAC and precision aerobatics in general. It's got a wonderful wing. I've never competed in IMAC so I don't know all the rules, but I thought the planes had to be of a IMAA legal size. I know the IMAA is no longer in operation, but I'm under the understanding that the 70 would be to small, which would leave you with the 50cc Revolver as your only option.

Hopefully an IMAC guy can chime in here, but there may also be a rule about the model having to be based on an actual full size aircraft, which the Revolver is not. But like I said, that may not be accurate because I haven't recently read the IMAC rule book.

Now I may again be misunderstanding you about your flying and you may want to simply fly an IMAC style for fun on your own. If you're not planning on competing, then I think the Revolver is right up your alley.

There was some discussion on this a while back. From what I can recall, the silencer was fairly effective. I think it killed about 200 rpm from the top end. With the DLE 20 being as strong as it is, I don't think it's a big issue on the Revolver. If you need to quiet the DLE down, I'd give it a shot..

The 55ra install will be in the 50cc Revolver. There is only about a 100 rpm increase over the original 55 per DLE. The 50cc Revolver will be a good fun airplane to fly in the IMAC "BASIC" class. Yes, I will certainly compete with it in the Basic class. No, it can not be used in the higher classes of IMAC because there is no full scale "Revolver". Maybe I can get them to believe that the Revolver is basically modified Giles. Smile, maybe one day I can move up to the Sportsman class if I can get them to believe that story. It does look like a "Giles G202". Now all I have to do is find a full scale Giles owner who can verify my story. I fly scale, I fly Quarter 40 pylon, I also fly turbines. IMAC flying makes you a more precise pilot, you really learn how to put the airplane exactly where "YOU" want it to be. That's my story and I'm sticking with it. Chic

OHHHHkay...I'm with you now. JoeMamma mentioned an 85" plane and you said "not for me". So I figured you were talking about the Rev 70. Joemamma must have been thinking of the 90" 50cc plane.

I'm sure the 50cc Revolver will be an excellent plane for your needs.

Mach 2, you are so right. Not that there is much difference between 85" and 90". However, I did not even know there was a 90" version of the Revolver. I wanted something to fly that was different from the rest of the crowd - thus the Revolver. I'm currently stripping the monocote off the airframe. I did not like the color scheme. My favorite colors are red, black, and white. So I have some recovering to do while I wait for the motor, receiver, servos, etc. to arrive. Stay well. Chic

Hey Mach2, did a quick check, that 85" wingspan on the 50cc Revolver is ------ 90". Well, I guess I shouldn't take the word of everyone that throws out a number. Now that I look at the wings, I see where the 90" comes from. The wings are approx. 40", add in the width of the fuse - presto - 90". My, my, always open to learn something new everyday. Chic

You didn't know there was a 90" Revolver, and you've got one. Now that's funny!

I'd like to see what she looks like when you're done with the covering. I'm not a fan of the color scheme of the 50cc Revolver either. Luckily for me, I like the scheme of my 70" Rev. Red, black and white should be cool.

By the way, did you ever get on the thread for the 50cc plane. I'm pretty sure there is one on here.

Don't ask me how that one slipped through. Must of been sooooooo happy to have my wife in Chicago for a week when the huge box arrived and it was smuggled into the workshop and the cardboard box disposed of. Smile.

All I need to do now is install the tech-aero ibec and put some foam under the battery. The cg is about 6 1/8". I wanted to be around 6.5". Maybe putting in the pilot will get me there. She weighed in at 9.5lbs. I plan on doing the maiden on Monday since I'll be on duty this weekend.

Mach2 that's a sweet looking model where do you end up locating your battery with your dual rear elevator setup?

It's on the bulkhead just behind the wing tube. I've flown one of my previous revolvers at 6.25" on the cg, so I was hoping to go to 6.5", so I may need to move the battery back. I put the throttle servo in the front because I wanted a short connection to the carb and I didn't think it would make much difference (it's a little hitec 225bb mighty mini) with the two big hitec 645s in the rear.

I am using a simple manual choke system, and I ditched the stock tail wheel for an aeroworks unit. Much, much better. And only about 15 bucks.
