Status: offline 		it does come with the longer composite arm, but im gonna have to drill through, or clearance the engine mount. As you can see, i dont have much room side to side.  I'll have to play with it once i get my servo in there and check the throws and everything.

also, the engine came with the throttle and choke arms on the same side which would have made the servo "push" to open the throttle. I had already moved the throttle arm to the other side so that it would be a "pull" system as well as to remove any chance of the throttle linkage and the choke lever (im going to do a manual choke) coming in contact with one another.

Let me echo S&S advice to avoid clevis links on this plane, and that goes for the throttle (and probably choke) linkages also. Ball links are immeasurably more secure when assembled with nylon lock nuts and blue loctite.

Status: offline 		hey guys, im still hoping to get an answer on this one.

i found that the brass bushing goes inside the backplate hole to keep it centered.

it seems like the nut that goes onto the prop shaft isnt exactly the right threads. it goes on a couple turns then gets tight. im guessing that the front black nut is a locking nut for that chrome or nickel plated nut that the smaller spinner screw goes into.

yes, no?

thanks,
Jeremy

The adapter nut is specific to the engine you use; iirc, the nut provided with the R70 spinner is a 5/16x18, which fits most .75-1.60 glow engines. It does not fit the DLE20 (8mm x 1mm) nor the DLE 30 (8mm x 1.25mm), so you have to get a different adapter nut. Check to be sure, but almost all adapter nuts are tapped on the distal (towards the front) end for 10-32, which would fit the SHCS provided with the R70 to attach the spnner to the adapter.

Tower has the 8x1mm adapters. Been there, done that.

Most canister installations that i have seen use thick silicone tubing - 1/2 or 5/8 - as standoffs from light ply structure which holds the canister. I'm sure a canister would get hot enough to deform monokote, as the canister probably would approach 300*F. Epoxy/glass might hold up, but AW, for example, uses silicone tubing, so that may be one of the best, most cost-effective solutions.

Status: offline 		I've got a mount that uses silicone tubing to hold the canister. I suspect I should put a layer of balsa sheeting on the bottom of the fuse since the canister will probably be about 3/8" away from the monokote. Also tempted to make an access panel that screws into the bottom of the fuse. If I do a decent job cutting the monokote off the bottom I could probably apply it to the balsa sheeting. Maybe I'll post a picture of the inside of the fuse to see what you guys think. It's a bit off topic though since it is for my PRC Sbach 342.

I hate to say it, but if you didn't reinforce the gear mount from the inside, those nice plates are going to be firmly attached to the gear when they rip out.

i did put a plate inside. it runs the with of the four bolts but only the two center are backed up by nuts because the outter two are damn near impossible to get to. its still squeezing it though.

even without the plate on the inside, the fuselage is still getting a lot less stress put on it by the landing gear.  with the two peices meeting in the middle, it would want to kinda "pivot" at the middle where the gap is.  like holding a pencil with two hands and using your thumbs in the middle to push down and break it. by adding the plates to the bottom and top of the gear it gives it a twice the clamping area and removes that flex point. It wouldnt crack in the middle with the plates.

adding the one inside will give it more strength from a front impact. such as an extreme nose down landing (which i bet would do more damage to the entire front of the plane, making the gear the least of the worries), or if you lose power and have to bring it down in rough area and catch the top a hill, fence, sprinkler piping etc...

are you a R70 owner?  if so, lets see some pics please.  i always like to see them to give me as many different options of parts placement as possible.

for example, im thinking of putting the fuel tank further back and putting the throttle servo infront of that. looks like it would be easier to run the linkage for the DLE20 if its in front...

thanks,
Jeremy

Status: offline 		Yes I have a Rev 70. On my second one as a matter of fact. A bad cross wind destroyed my first.  After ripping the gear off the second one I glued and screwed a block about an eighth of an inch above the gear mount. Screwed it solid from the firewall and former behind that. Then counter sunk screws through the gear mount and into the block inside. It is holding solid now.  I put large washers (actually aluminum helicopter blade spacers) under the outside bolt heads to minimize the the gear leg twisting. I think if you search my profile you can find all my posts and any pictures I've posted.  Don't have any of these current mods though.

what motor are you running?

and what were the circumstances when your gear came off? and did you just have them mounted with no modification when it broke?

I love the plane. The looks especially. Everyone at my field comments on how good looking it is.  I'm running the DLE20.  Great little engine and perfect for this airframe. Many others are using it too. It can be mounted with the stock plastic mount with some slight mods and requries some creative throttle throttle rod bending, but if its not a challenge, then its boring.  I got lazy on my second Revolver and just tried using extra epoxy and a few strategically placed screws to reinforce the gear mount. Held for a while, but one hard bounce took the gear off. Usually it breaks out clean and is easily glued back in.  (after some internal beefing of course)

I'm also a member of the Rev 70 \ DLE 20 camp. Love the plane and the engine and this combination. btw - I usually have two 70's and two 59's in my fleet - due to crashes I can't remember how many I've bought - have another 59" fuse in the post.

On the gear, you'll only know if your method of reinforcment works in time. I had a few sets rip out - front and rear - until I developed my own reinforcement techniques (detailed in this thread a few times).

Good luck with the plane - I'm sure you'll love it.

I fly on grass strips at two different fields. You guys must fly at some rough fields as I still have my stock landing gear and I have only slight re-enforcement with a small aluminum plate (just under the screw heads) like mentioned above. Nothing special at all and my gear are holding up well. I have a 91FX on mine. I am considering a DLE20 this winter, but not sure yet as I am thinking about a 30cc setup on another plane.

I did pull a set of gear out of my small revolver but it was just bad flying that day on my part. I only did that once and since then the gear on both planes are doing well. One thing is for sure, the larger Revolver will definitely get some attention even with the best of planes. It has a nice "style" in the sky and looks decent on the ground. For the money, it is really a good airframe needing little mods.

im gonna be in the DLE20 club too.  and maybe the reason that Luchnia hasn't had any gear issues is because he is running a lighter engine....

i think i may put in a larger plate on the inside (maybe wood so the plane doesn't end up weighing 50 pounds). if im going to have one inside, it may as well grab as much surface area as possible.

OH, QUESTION!!!! where did you guys get your spinner nut that goes on the prop shaft of the DLE20 and has the right threads to fit the skinny front spinner bolt?  THANKS!!! Im having a hard time finding one....

Here you go. Don't understand why Tower Hobbies doesn't sell this. The thread size for the DLE 20 is 8 x 1mm.
