RE: DL-50 engine
Speaking of TBM, I bought a TBM prop to a bad landing and couldn't buy anything else without mail ordering it. I tried it today and the tach was showing only 6000rpm, verse around 6800-7000rpm with the ProZinger I broke. Both props were 22x8. By ear the engine seemed to be running at a higher rpm than the tach showed so I probably should check the battery in the tach. What is the general opinion of TBM props? (I did adjust the HS needle a little to get the rpm up to 6000)

I had a TBM 22x8 an mine till it picked up a rock while I was tuning. But I got 6800 RPM before the rock chipped my brand new prop. (Lesson Learned). I now have a XOAR 22x8 and get just shy of 7000. At my altitude of 5000' ASL I thought that that was really good.

RE: DL-50 engine
I've been thinking abouttrying a Vess but the A,B,C has me a little messed up. Before I order one I'll have to figure that out. Maybe the 22A? This Saturday I might be able to maiden my PA Edge 540T/DL-50 Combo

On that plane a 22B or a 23A would be a good choice, the nx 22X8 would also be a good prop. I have a PA edge with that same engine and it is way over powered. It is balistic.

RE: DL-50 engine
Mine weighs in at 14.3 lbs without fuel. The problem I've had here is always being under powered. A 40 size plane with the top recomended engine is just not enough. I have to use 60 size engines to get the power needed say a .91 4-stroke. I'm hoping that this will not be an issue with my edge. I'm tired of always being under powered.

The two wire cable that comes with the DL is a extra lead that can be installed on your battery pack or switch harness to match the Futaba battery lead on the RCXL ignition. You probably will not need if you use all Futaba wire harness parts.

Greathobbies here in Canada will be selling the DL100. At $750 not bad price but I was expecting it to be a bit cheaper.

RE: DL-50 engine
It will be interesting to see What DLusa will seel them for. Just checked their web site, no price yet. If their as good as the dl50's, still cheaper than the other guys and worth the price, maybee.

I wrote Bob with this DL 100 question. He said "later in May", estimated price somewhere around $750. Includes two mufflers, RcExcell Dual-lead ignition. If it is as good as the 50, but double-good, then it will be well worth it, IMO.

RE: DL-50 engine
In that pic, .. looks like they have decided to make just one muffler ... and use it on both sides instead of a left and a right muffler. Looks odd.

RE: DL-50 engine
Agree it might look odd, but saving the cost of a "left" v.s. "right" may be the reason; although I have to admit, I wouldn't mind paying $50 more to have it look "proper"...

RE: DL-50 engine
Yes, very true.
On a DIFFERENT topic..... just curious.... do you all drill your props in an "X" pattern so you're up against compression at 2 o'clock, or a "+" pattern, where the blade is exactly vertical (or horizontal) ??
I know my preference, and rationale, but would like to hear others????

RE: DL-50 engine
personally I like the x. I tried the+ and didn't like it as much. It didn't feel to me like I was getting the full force of the flip at the +.

RE: DL-50 engine
I very much perfer the X. I stand behind the plane and personally feel like I get a much stronger flip with the compression starting at 2 o'clock(10 from behind)

RE: DL-50 engine
I noticed that "+" pattern in the photo as well and had the same question. I use the "X" but don't know why. I do have a comfortable "flipping" position at about 2:00 posisiton. I wondered if there was any structural reason to drill props one way or the other. Any opinions?

The leverage available with having the prop just before TDC at 45* seems to be important; at least I have NEVER positioned (drilled) a prop for any other angle, except if I made an error drilling.
I just wanted to see what some others preferred, as I thought maybe I was missing something.
Any others??? "+" or "X" ??

200 DL100's were delivered out of the factory on Friday. They should start showing up soon. I will have one in a couple weeks (figures crossed).

RE: DL-50 engine
When you talk about negative expo, and the other guy says he uses about 30%. This can be very confusing to most who have Computer radios. JR neg. expo makes the center more sensitive and pos. expo makes the center less sensitive. Know on the other hand Futaba is just the opposite neg.expo desensitizes and pos. expo senisitizes the stick at center. I try not to asume every body knows this, so could you guys explain a little more in detail to which radio set ups you are using. I'am sure evey body else has the same question. The new guys to 3D could get them selfs in a world of hurt by interperating this incorrectly, Just a few in my heard.
One of our members just got a DL50 and has had the same problems with his stock muffler.

I run negative expo on my throttle and the transition is as close to flawless as you can get. IMHO You can take a look at it for yourself in the tuning video I posted. The engine behaves just the same in the air. BTW the reason I used the expo is to get the throttle response correct for the position of the stick. Oh, one other thing, the DL seems to perform much better then the DA from what my hardcore DA friends tell me. They're dumping their DAs in favor of the DL.
