If you go to Vess.com they have a huge line of different airplanes all with the Vess prop and different size engines to show which prop is better A-B-OR-C prop on the different size engines, has anyone checked that out, they seem to really turn up quickly with tons of power.

Happy this is the DL 50 thread, so I don't have to respond to that....

BTW - those running the Vess... if you have a "typical" spinner, you will need 45mm x 5mm bolts for the prop. This will permit about 4-5mm of threads into the hub. Next jump up, 50 mm will require trimming, perhaps. JR Hardware ( http://www.jrhobbyhardware.com/shop/index.html ) and Fastener Express ( http://www.fastener-express.com/inde...S&Category=245 ). are both good suppliers for small quantities of these.

JR Hardware also carries the socket head screws that fit the Hitec, Futaba, and JR metal gear servos.

Bob, Just finished tuning my DL with the Vess 23A. Video to follow.

Okay, plane is strapped to a 1" steel stake in the ground. One hand for the camera and one hand for the Tx so no tach or thrust checks. I did tach the engine prior to shooting the video and it was at 7400 rpm top end. I was tuning to get my transition right where I wanted it and I think it's pretty darn good here. Enjoy!

Just LOVE watching the fuse dance on asphalt and that wing tube work it's way out..... that is a great vid, and shows a VERY well adjusted engine. I think you should send to Bob at DLUSA as an example. Ain't no missin' the fact that it is running strong *and* smooth. Great job.

Can't wait for a weather break.

I don't mean to be a smart ass but You should never run your engine on the ground with no wings attached, It is a good way to tear your fuse up, How do I know? been there done that, The wings help dampen the vibration.

Waco, You are "right on" with that remark! I had my YAK stand up on one wheel without the wings on. I was straddling the fuse at the time and cought it between my legs before she went over. Never again! That could have been very ugly! Very good point. Thanks for being on the ball and spotting this. I agree 100%! SG

Yep.
Some fuselages will get damaged that way.
Some won't.
Not sure there's a "hard and fast" rule, there, Waco...

I think a lot depends on the rigidity of the landing gear, the surface it's resting on, etc.

Agreed that it's not the "best practice", but it also isn't the end of the world on many airplanes, either. Point well taken, though.

I have to say that that is the first time I've heard of that. Been running them this way for 7 years now without a problem. I usually don't run them very long, just enough to tune them. May have something to do with the planes themselves. Thanks for the tip though. As far as straddling them, I loop a nylon strap over the rear of the fuse in front of the vertical stab and under the horizontal stabs. That's on a 1" thick steel bar driven well into the ground. That means the plane can lift the tail about one inch. Can't imagine it lifting up on one wheel unless you had a serious torque issue. Good thing you caught it.

Here you go guys. Crapy video phone and all sorry about the quality. Had a dead stick at the end. Went for the duel rates and got the kill switch. oops.

Motor ran great WOW!

Idle at 1300rpm at the end of the day and 6950rpm with a xoar 22x8 32 to 1 lawnboy

Paul, Sounds like you have that motor dialed in sweet! Plane looks locked in too! Congrats! Very nice looking combo!
Sigflyer, I have one of the CMPro Christen Eagles waiting for my lazy butt to put the BCMA 26cc in it that's on the bench. Beautiful plane!!

On its way. My neighbor and flying partner have the same camera and have practiced the last four years by video taping each others flights every weekend. It's really tough to get a good video of an RC plane.[:@][:@][:@][:@][:@] Here's the tape I shot of Kyle "The Alien" Woyshnis at our air show this year. I apoligize about the off subject guys.

Lou55, I secure my planes the same exact way!!! It was very windy on the day of this incident and I think the 20+mph gusts may have had some effect but it was a close call to say the least. Also...I do not believe you should rely on a nylon rope tied around your tailfeathers to stop the torque from rolling the fuselage. I backed off the throttle real fast but my first reaction was to pinch my legs together. Must have got that from my wife!

LMAO Now that's funny! Actually I use a nylon strap about 1 1/2" wide and I never do anything in 20 mph gusts. LOL The process is simple, you put the entire tail end of the plane through the loop and then pull it back under the horizontal stabs. Then you hook the loop to the steel stake. It's a lot stronger then some of the "twin stakes" I've seen guys hook their horizontal stabs behind in some of the videos on here. You would virtually have to rip the airframe in two for it to fail, not just rip the horizontal stabs off. I also normally have my next door neighbor and flying partner there helping me but he just flew back from seeing his folks last night and wasn't available yesterday. Looks like this.

LOU55, I use strap in the opposite direction. I place the tailwheel in the center of the looped strap laying on the ground, then pull it up and over the stab tips. This helps keep the stab down and does not interfere with my externel antena. I ran into some problems with the antena internal so I run it up and out to the top of rudder. This is the main reason I loop my restraint over the top of stab. The downfall to using the strap is that it sometimes loosens the covering where the stab meets the fuselage. I don't see how some guys can have so many models at once. Flying and maintaining 2 models requires a lot of TLC. SG

Not to mention the ingestion of dirt/dust into the engine.

Run the engine at night in the same place and have a car shine its headlights slightly in front of the prop. After seeing what I'm talking about, I bet you will never run your engine on the ground longer than you need to again.

I discovered it by pure accident and was astounded at what I saw. And this was on a grass field. Asphalt/concrete is worse.

Ed, You're telling me!! I just got back from Southern California and drove by a RC flying field. Everything was dirt and the guys were starting their planes up on stands then they would put them on the ground and take off immediately. I guess they call it the "Ground" because that is what it is...ground up dirt! I had a ZDZ 40 and had it on my test stand and was amazed at the dirt that the prop was picking up from the concrete it was on. I had shorts on and that is how I noticed it. It actually stung a little. To tell you the truth, I was actually more concerned about the prop than the engine. Duhhhh! Air cleaners??? I know ZDZ has some nice ones. Tell me of some other sources for non-restrictive air cleaners that you know of that will fit the DL-50. SG

I have been reading up on mufflers and have a question. Why do most muffler manufacturers think that the muffler has to be bolted to the engine and then wrap around the side and behind cylinder all in one piece? Why doesn't someone make a muffler that bolts to the firewall, insulated of course, and have a simple manifold bolted to the engine and connected to the firewall mounted muffler via a flex tube. This would have a double advantage. The weight of the whole muffler would not be hanging on the engine and would result in less vibration. I realize that there is the high performance cannister exhaust system but I just want a simple "in-cowl" muffler for my DL-50! I am going to make my own setup and see how it works. It's nice having a full service machine shop and TIG welder at my disposal!!! Speedy

Speedy,

Like this? Cast, machined header, soft-mount muffler, aircraft grade aluminum.

Rich, This is exactly what I am looking for! Is this setup specific for the DL-50? What will be your projected price? Last question....Could you make the exhaust stacks a little longer so they can be trimmed to length for different cowl configurations? I am not "Dirty Harry" but you just made my day!!! Count me in!
