I assume the need for a new fus was because of a crash? The RX could have been damaged if it was in a crash. If not try to re bind.

RE: Magnum ALA Vicman
[quote]ORIGINAL: combatpigg The thick trailing edges on delta elevons leaves them with more structure to resist flutter. [I've never experienced elevon flutter either way] The blunt, "flat plate" control surface gets into the airstream with less deflection from neutral..so this would contribute to sensitivity..or in other words quicker response from neutral. I think most control line precision aerobatics flyers [who get down graded on every slight burp their models make] would say sharp trailing edges promote smoother tracking and less sensitivity around neutral control. As far as RC speed planes go....thick trailing edges just look "hen house"...........[:D] [/quote] Pattern and IMAC airplanes have been going to thick TE for a while now. I agree that the look is odd but the result is worth it. I would agree that the effectiveness around center is better and thus on a CL model could be twitchy. R/C guys would just dial in a little more expo, CL guys would move the lines in on the handle both would benefit from the higher degree of control close to center. At least that is what the CL sunt pilot I hang out with seems to think. We are gearing up to make him a set of thick TE elevators and flaps now. My race planes do all have razor TE, to keep them strong and still the whole stab and fin are glassed with 2 layers of 1.5 oz cloth and bagged. The elevators and rudder are separated after the bagging process.

RE: O.S 65 LA help
It's having fuel draw issues. Check that no fuel lines are being pinched, fitting on muffler is not partially blocked and that the air bleed screw is not all the way open.

RE: Magnum ALA Vicman
The thick TE will make the airplane more stable around center and make control surfaces more effective. IMAC guys have been taking advantage of this for years. Aerodynamically we don't start seeing advantages until close to 200 MPH unless its a sailplane. Sharp TE done right does add that certain seriousness to a speed model though.

RE: Help in ID'ing plane
Depends on the region. Over here where I fly we love YS engines. True they are not as easy to set up as others and take special care but once you learn the care and feeding there is not a more powerful and reliable 4 stroke out there. Things I have learned about them, always use 100% synthetic fuel, OS F plug, set the regulator to flush with housing and for the most part leave it there and always let it run a little bit to build pressure in the tank before advancing the throttle.

RE: DLE 170 exhaust
You should stick with a proven canister setup. Usually header length is critical on a 2 stroke. A while back I did a canister install on a 38% Extra and to get them to fit I cut 2 inces off the header. The engine transitioned like poop. I ended up putting the stock DA mufflers back on. The best sounding airplane I have owned to date was a Comp ARF 260. It had a DA 150 with stock mufflers but a 3 blade prop. Running at a slightly lower RPM and the loss of a lot of prop noise made it almost sound like a well tuned motorcycle.

RE: moving CG around
So true Bob, that has been one of the most difficult thing for me to get across to people. Trimming for me is always a work in process. I kept my answer on this one simple so that the OP would hopefully let us know why he wanted to play with his CG location and then we could go from there. In the past trying to explain that CG will change everything from landing speed to control cross coupling with about a dozen things in between always seems to spark arguments. Seems the old pilots tale of a nose heavy airplane always being more stable is alive and well.

RE: Tuning with your snoot up in the air
I'm amazed at how many of you guys think you are going to get a good tune while on the ground. Sure get it running well but do your fine tuning based on what you see and hear while in flight. The conditions between a static run and in flight are so different that you will never get it 100% right on the ground. I tend to laugh when I see someone run 1/2 a tank of fuel on the ground trying to tune while the engine just gets hotter and hotter.

RE: moving CG around
You need to know which way to adjust. Adding weight to the CG only adds weight. What is your airplane doing that makes you think you need a CG adjustment?

RE: Trashman Classic Warbird Race Sept 22 and 23
I just got aff the phone with JR and he indicated he will do what he can to get you out of there ASAP Jake. As for the prop issues. Sounds like some testing is in order. Making the props stronger with the current plastic formula will just add weight and IMO will be two steps forward and one backward. They used to make some props by using a CF re-inforcement instead of the grey fiber that is typical. Maybe convince them to mold some props in the CF formula? The other option would be very expensive and that would be for someone to come up with a set of molds to do a CF/epoxy prop. That would require CNC aluminum molds. We have the capability just not sure how guys would feel spending 40.00 for a prop. I really wish Bolly was still in business. As a side thought, I remember the old Top Flight nylon props needed to be boiled before use. This somehow increased their strength. APC is a type of nylon.

RE: landing bounce
[quote]ORIGINAL: acdii The plane is tail heavy. Doesnt take much either. I have a 4*120 and the first couple times I landed it, it would bounce. Turned out to have lost almost 2 ounces of nose weight from the time I first ran up the engine, to the time of the first flights. I found the weights in the back of the truck and glued them back on, now the plane lands good, without bounce no matter what the speed is. [/quote] This is half of the equasion, Its a combination of CG and gear placement. bringing the CG back will increase the distance between CG and wheel axles. I initally set up my designs so that the wheel axles are about 20% to 25% forward of the CG. After test flights and CG adjustments I usually have to adjust the gear as well. Too far forward will cause a sudden change in positive AOA and the rusultant lift will bring you back in the air. Too far back and you will nose over. In this case, I would bend the gear back about 1" and give it a try. For trike gear adjust the nose wheel so the airplane sits slightly nose down at rest.

RE: Making a glass cowl from the inside of a plastic one ?
[quote]ORIGINAL: acdii Im making a mold to mold a cowl for my Dewey. The one it came with is too short for the 4 stroke, and it was cut up for the original motor. So I made a base plug from styro foam, and covering it with Bondo. When I get it to the shape I need, then will give it a coating of resin, polish it and make the final mold. I wish I could do what you are doing, it would have been done by now! [/quote] The bondo will dissolve the foam. You need to fiberglass the foam plug with epoxy resin. If it's just a one off, you can simply dissolve the foam away with laquer thinner after you have glassed it. What you have left is a fiberglass cowl.

My engines saw hundreds of flights, ran great and did the same thing. I wouldn't worry about it. A 32X12 is going to be too much prop. The best props for the 150 is 32X10 for sequence flying and 30X12 for 3D

RE: Servo flutter
[quote]ORIGINAL: golf4two Unplug and then reseat all of the connections from the receiver to the servos a couple of times. That may fix the problem. If it does, you may have to do that again after a while-dirty/faulty connections. Happens to me on a couple of different planes from time to time. Turn on the xmitter and plane, then check aileron response before securing the wing to the fuselage each time you go the field to fly. Using two channels and mixing makes it a bit more complicated to trim the ailerons. [/quote] How does using a mix make it more complicated to trim the ailerons?
