Granpooba - first, nice handle. And are these your first Revolvers? Are you building \ flying the Rev 70 first? Would love to see build pics of the Rev 90. Maybe post to wjcalhoun's build thread?


Have already been flying my R-70 with a Saito 91 pulling it, for a couple of years now. Very, very pleased with this plane/engine combo.

Just this past week I put in my new Aeroworks Extra 300 QB with a DLE-20. It crashed on its very first takeoff. Cause was and their is no doubt about this, is that the vertical and horizontal stabs came off. Upon examination it was determined to be a total structural failure do to quality of or lack of glue, probably a combination of both. Only glue that was holding was the epoxy that I used to mount the horizontal stab. Also, the tail of the fuselage was very weak under the horizontal stab and this contributed to the failure.

I came online here and inquired as to what planes people were installing their DLE's 20's into. Got various replies, but what stood out for me that many were putting the DLE-20's into the R-70's and were stating that it was an awesome combination. Thus already having a DLE-20 and very pleased with the R-70, I ordered another R-70 and have already received it. Will be starting to put it together this coming week.

Have the R-90 on order. No hurry for this one as winter will be fast approaching here in the Northeast and will need a couple of models to help get past the winter blues. Have already decided to put the DLE-55RA into the R-90.

As I originally stated, I am very pleased with my R-70 / Saito 91 combo, and will be interesting to see how the R-70/DLE combo compares. The R-90 with the DLE-55 should also be an awesome combo.

Guess I will have to build a hangar just for my Revolvers ..............

Their are some other threads on RC Universe about the Revolvers with the DLE-20's, with pictures. Check out the threads about the DLE-20's, that is where I found and got most of my info about them. With just a little searching, others should have no problems finding all the info that they need or want about this combo. Very interesting reading, at least for me.

I should add that if you check out " You Tube ", you will find some video's there of R-70's with DLE-20's.

Have fun and enjoy.

He said they could not meet the worker demands because another regional country, I think it was Bangladesh, was more then willing to provide labor with even fewer benefits. I was shocked when he said "they were on a race to the bottom". Those were his exact words. Supposedly cheaper energy is starting to bring jobs home. Lets hope so.

DA vs DLE; I don't think it is a fair comparison, like apples and oranges. The DA is a work of art with better components. A friend of mine has the DA 50 and it will idle at 1200 rpm. I have 2 DLE 55s and they are dependable work horses. I heard the idle is contributed to the premium bearings, but don't really know. I am the last one to be able to give an educated opinion on this issue, but my gut feeling is that they are not the same animal.

Status: offline 		Just curious, did AW take care of you? I am somewhat disapointed in some of the planes now days breaking apart in the air. I can see after some serious hard flying, but just on maiden speaks volumes!

I read somewhere that folks were taking long pices of dowel and attaching an epoxy brush and thinning epoxy then applying it down inside the back of the fuselage? To me, this is ridiculous to think that we would have to do that!

To date I have never had to do that, however my concern has grown some now when you see AW planes get so crummy and yet charge a bit more than their competitors for planes shipped from other lands

Status: online 		wjcalhoun - was working on my flat spin this morning (Rev 70 \ OS 120 4s), and I think I'm getting it. Not sure, though, the best way to start and the correct order of control surfaces. This is what I'm doing - climb high, go into a slow dive, full left rudder, full right ailerons, full up elevator, up throttle to 1/2-3/4. Is that the correct approach and order? Didn't get it consistently, but did get it a few times, and MAN is that fun! other question - do you use high rates for your elevator and \ or ailerons? (I did try high-rates for elevator on one of them, but didn't seem to make much difference, plus I had to remember to switch back to low-rates on elevator so I would not lose control.)

Also am getting more comfortable with outside loops (though I'm still doing them up high). Did some practicing this morning and realized that you have to move ailerons TOWARD the side that's dropping - once I was aware of that I felt MUCH more in control. it's counter-intuative (you want to pull to the OTHER side - though you'd think I'd know that from my other inverted flying...).

Once I get this I'll try inverted flat spin. I love the excitement of learning new moves!

No Sir, not going with a tuned pipe on the DLE-55RA. Have talked to other fellows and read that the RA already comes with a Pitts style muffler. I believe that if you were to purchase the standard DLE-55 and wanted to add a Pitts muffler, it would cost you about an additional $80.00 to $90.00. Thus, I just thought that I might just as well opt to purchase the RA with the Pitts muffler and save a few dollars.

Have never flown off of snow, but I probably should considering that we only have three seasons here, which are July, August and Winter.

Also noted that the RA is $60 more, but if you were going to get a Pitts-muffler anyway it seems that it does save you some money and ordering the extra muffler. Also just noticed that the RA's peak HP of 5.5 is at 8,500 RPM, and the DLE55 is at 7,500. Any idea what that's about? (wonder if it has to do with being more in sync with a tuned pipe? or maybe the Tech Notes are not accurate.)

I may just call TH tomorrow and ask.

I just bought my AX120 and as you said, it fit perfectly in my Revolver 70.
I also noticed it weighs only 2.4 ounces more than the AX75 recommended.
Did you have any problem making the CG the right place?
I hate to add more weight, but I figure if I place the battery next to the receiver instead of the front, it should be enough to help balancing.

Thanks,

Status: offline 		Microdon, The upright flat spin starts at level flight and idle speed to bring about a stall. Push into the menuver with slight left aileron, apply left rudder and then up elevator. The more throw the flatter the spin. I don't use aileron after the spin begins, but some planes require aileron to flatten the spin. Also the more neutral the CG the flatter the spin. You can play with the pitch angle of the spin by changing rudder and elevator deflection as she drops. For inverted, bring plane to inverted flight, idle, right rudder and then down elevator. Pull out is induced by releasing the sticks and then flying out.

Status: online 		S&S - thanks - will try your approach.

I just had a close call, from being careless. I was testing a 35cc gas engine in my kitchen (its mounted on a H9 P51 150). Had the plane fuse on a stand (on the floor) and have a rope around the tail to hold it, and an exhaust hose venting to the outside. I test lots of engines in my kitchen. But this setup was more awkward because of the stand and the position of the exhaust hose. Got the engine running nicely, controlling choke and throttle from my radio. On second startup I had the engine running at just above low throttle, and was stepping around the front of the plane to get behind (to hold it while I revved it up). Evidently this time I got lazy and didn't lift my leg high enough, and WHAM - the prop hit my right foot in the toes. BAM - that hurt. Was so sudden I wasn't sure how badly I was hurt. Fortunately I was wearing socks and leather slippers (I don't usually wear slipper). At this point I'm still was not sure if I had broken toes inside the slippers.

Stopped the engine with the choke. Also fortunate that the prop was a wood Zinger - it broke. After an hour or so the pain subsided. Took the shoe and sock off - looks like no broken toes, but I do have a bit of dent in my big toe. Glad it wasn't an APC prop.

No problem with CG; my battery was aft; mounted just in front of the rudder servo (and i did have two elevator servos mounted way aft in the fuse).
That is a great combo. Have fun with it.

Microdon: I start my (upright) flat spins with a stall->spin; the wings have to stall first, so slow, nose high until the nose falls, then full L aileron, L rudder, full up elevator into the spin with advancing throttle to accelerate the spin. Once you have a fast coordinated spin, begin to cross the aileron (slowly) to the R and she will flatten out. I do use max rates for that maneuver; to exit, point the nose at the ground to gain airspeed, pull the rate switch to low and either pull (+g) or push (-g) to horizontal. For inverted, start inverted, stall spin with full down elevator, full L rudder, full R aileron, accelerate the spin, and then cross the aileron. If you cross the aileron too soon, or too quickly, the plane falls into what looks like a blender. Key is, you have to stall the wings.

Oops - S&S - missed your post; looks like our methods are about the same; sorry to duplicate instructions.

Mike - fortunate it was your toes, not your fingers or head!

I believe that the Tech Notes are not accurate / misprint. I think that their is only about 100 RPM difference between the Standard and the RA.

Status: offline 		Micro, sorry to hear of your accident. Hopefully no broken or fractured bones. About 3 years ago, I kicked an oak chair at 2am on my way to the dark bathroom and fractured my big toe. Had one of those big flat hospital shoes on for 8 weeks. Didn't know it was fractured until I tried on my shoes and the throbbing got more and more intense with every step.

My flat spin method is utilzed with a 50 cc extra, and may not work with the Revolver. Good luck with your next attemp and your big toe. Please don't take this the wrong way, but having a gas engine running in your house is very dangerous, even with the pipe to the outside. That pipe should extend well beyond, 10 feet or more, from the outside wall. We have had people in S Florida die from generators running outside, but near a window; or cars left running in a garage, even with the interior door closed. I wish you the best.

Status: offline 		I haven't tried a flat spin with the Revolver yet but I have done them with several other planes. The location of your CG seems to play alot into how you execute the flat spin. I've been moving CG back a bit on mg planes to help with harriers and hovering. Moving the CG made it harder to find the sweet spot for flat spins and inverted flat spins. It also had a huve impact on KE spins....I can barely do them now.

Status: offline 		My understanding is that the CG will effect knife edge menuvers. For instance, during conventional knife edge, my Extra pulls to the canopy when it is flown nose heavy. And the flat spins are flatter with a neutral CG, while the nose tips downward when nose heavy, although I can compensate with aeleron input. But I fly with two other guys, who also fly 50cc planes, one is an EF Edge, the other is an EF Yak, while I am now flying the EF Extra. Each of us has a different way of performing knife edge spins. I think the aerodynamics of each of these planes also effects execution. My EF Yak will pull to the gear in knife edge, even with a neutral CG. WJC's instructions may be more appropriate to the Revolver.

And I also leave other windows open, on the other side of the place, for extra ventilation. Believe me - I don't have a death wish!

KE and flat spins still beyond me - unless done by accident!

Do you guys know what you're running regarding CG? I'm at 1/2" back, and the plane seems just a hair nose down from neutral there. Harriers and high alpha stuff seem to be working OK here?
