    I think that if my first small gas engine was the DLE-35RA and not the DLE-30 side dump, I may never have gone electric. The DLE-30 was that much of a headache. I'm guessing that since I'm flying the 11 to 14 pound planes almost exclusively now - because how well they fly and how easy the are...

    Yeah, it makes sense. If you like to tinker with engines, there are a few upgrades you can do to any DLE that will make it better and perhaps last longer, but once you do that, you probably would spend about as much as you would have on a DA in the first place. That's what happened to me, so...

    A club buddy has the DLE-60 twin on a 19 pound airplane, and it's running really well, but not swinging a very big prop, not very compact, and not very light. We always ran a 23x8 beech on the DA-50, and sometimes the 23x8 Laminated Xoar for IMAC, but he settled on the 22x10 standard Mejzlik on...

    In total agreement. I've always considered it a non-issue, and that's why I feel like it's important to try to put it into perspective. I like and respect Gary and he knows that we can mix it up a little without that changing. Personally, I'd rather address the weight trend. I'm beginning...

    Looks right to me, but what do I know about hockey? :cool: And if anyone wants to convert force in Newtons to Kg or lbs, just multiply by 0.10197 to get Kilograms and then multiply Kg by about 2.2 to get pounds, so 7761 N = 1745 pounds of force. And Newton-meters should really be written as...

    Well, kind of, but probably not the way you wanted it to. That sounds like a lot of plane for another $100 to me, even if I liked the 71 Slick. If you are trying to convince me that the split stab is a negative because it costs you for another servo, it ain't gonna work because it's like...

    So you paid almost exactly $100 more for a bigger and heavier plane with a split stab and stab tube, than what I paid for the smaller plane in November 2013. Sorry, but I still don't see why this is so shocking. Maybe it's because we could save $128 if we went to pick them up, or maybe I'm...

    Possible, but I disagree. Two of my favorite planes right now are the EF 78 Extra 300 and the 3DHS 74 Edge 740. Are they the same size? No way, and this is why I mentioned fuse length in my other post. The 3DHS 74 Edge is 69 inches while the EF 78 Extra is as long as my Godfrey 85 inch Extra...

    Sure, but people are talking as if the product cost is the same and EF charges three time the amount to ship. The EF Extra EXP with the 70" wing span and 70" fuse was $454 to my door, the 3DHS Edge 540 with the 74" wingspan and the 69" fuse was $485 to my door, and the EF Extra 300 with the 78"...

    There are actually a few things going on here again, so let’s see if I can explain in a few sentences what it took me an entire 4 credit college course to understand, because there are different vectors involved here. I'm thinking that maybe the better way to illustrate this is by looking at...

    Actually, it's getting physical in here... this is all pure and simple physics 101. I’m not sure I can explain this further in a thread like this because there are too many force vectors influencing the “Change in Angular Momentum”, but here’s the last stab: We have gravity torque, which has...

    Consider the shaft in this video as the motor/engine shaft and the weight as the propeller. Consider the shaft is pointing striaght down to the ground, so that the attitude of the plane would be 180 degrees from straight up. The angular momentum is applying a supporting force vector...

    Your missing the point. Forget about the weight, and forget about the rotation around the string once the wheel is perpendicular to the floor because I'm not talking about the "torque chasing the angular momentum" here (gyroscopic propulsion).... the wheel would spin flat and horizontal to the...

    I don't really understand the post, but I've bought a 3DHS with a 69 inch fuse and 10.8 pounds and an EF plane with a 76 inch fuse and 13 pounds. The 76 inch fuse EF plane cost $450 with $127 shipping, so $557. The 3DHS plane with the 69 inch fuse cost $440 and $45.21 to ship so $485. Would I...

    No. A rapidly spinning object of any kind, whether it be cambered and pitched like a propeller, or not, will "precess" in a direction determined by the torque exerted by its weight. This is a bit different than P-factor. P-factor is induced as a pitched lifting body (like a cambered and...

    Okay, here it is. Precession is induced with RPMs. So if you start your roll to the right, and control throttle through the first 1/4 roll, you don't need rudder unless the plane can't roll axially at all, and there are some ARFs that fit into this category. If the plane is set up neutrally...

    Good guess about laminar flow with the P-51, but no. No. No. Very warm, but unless you look at the declassified design plans for the P-51 documents online, you may not be able to guess. But increasing the precession on the first 1/4 roll to 90 degrees KE while rolling to the right first...

    I guess I should also mention that some of the physical forces of the rotating prop has a little to do with it too. Consider precession, throttle management, and how yaw affects the roll. So although no other control surface input is needed, throttle management is involved and the rotational...

    Design. I'll give you a hint... when they were designing the P-51 at North American, they did something. My IMAC plane had that same something designed into it. :flyer:
