Hello about the rudder servo, it’s posible to put in the rear part ?

@eddrakes 22 күн бұрын

That is a bit difficult to tell whether there is a recess available for a rear-mounted rudder servo. The problem with doing that is the extra weight then applied at the rear. That would have to be counterweighted at the front - normally by locating the 10S/12S batteries a bit further forward. Even with the mid-mounted rudder servo(pull-pull) the batteries are already nearly disappearing under the cowl at the front! It is all up to you, of course. Just perform COG checks before fixing or cutting anything! Good luck. I am very happy with the mid-mounted rudder servo.

Sorry, no. It takes considerable skill and experience to film aerobatics. Most people expect to get away with using a mobile phone!! Sorry, it really requires a tripod and dedicated video capture. The cameraman's zoom management has to be good and he should have a good working knowledge of the aerobatic sequences to be filmed. Quite demanding really.

This plane comes ready to fly 3D and is not appropriately setup for precision aerobatics (PA). For PA, I have changed out the servo arms for 25mm aluminiums. Also, I calculated that the COG should be about 30mm forward, of that nominated, to prevent unwanted pitching in a straight line.

@eddrakes 9 ай бұрын

Innitial flights were based on the nominated, centre-of-tube marking for COG. The plane was very pitchy. A quick geometric check showed that the "normal?" COG should be more like 30mm in front of the nominated COG. I added 120g of lead onto the motor box, just behind the motor, to achieve this new COG. This was WAY BETTER for my flying style - precision aerobatics.

Prop pitch is conventionally measured at a specified radius, usually 2/3 or 3/4 of radius. This is entirely arbitrary, since the measured pitch will usually be different at each radiius. Pitch measured in this way will allow a rough sorting of props, but it is useless for performance analysis.

@aeromodeller1 11 ай бұрын

There is geometric pitch and aerodynamic pitch. They are not the same. Geometric pitch is how far the blade element chord would move forward as if it was a screw, moving with the blade element chord tangent to the line of advance. Propellers can not work like that. They do not screw through a solid medium. The blade element must have an attack angle relative to the path through the air to develop lift. The distance travedled through the air is less than the geometric pitch. I prefer to call that the advance; the distance traveled through the air in one revolution. My comment was on the geometric pitch. The geometric pitch can be calculated from the blade element angle at each radius. Almost all props I have measured have a different geometric pitch at each radius.

@aeromodeller1 11 ай бұрын

That will give you the pitch at the 30 degree blade angle. But the pitch usually varies along the blade, different at each radius.

@eddrakes 11 ай бұрын

Prop Pitch definition is "the distance a propeller moves through a fluid in one complete revolution", not the angle of the prop which varies through its length. Ask if you need a more complete explanation. Sorry if you are having trouble understanding this... Watch again, listen to the instructions carefully. It works very well!!

@eddrakes 11 ай бұрын

This is a beautiful flying plane when you arrange your balance point at the COG nominated, center of the tube. In your case, I assume the battery is as far forward as it can go. A few of my planes were a bit tail heavy. In these cases I bolted lead weights onto the motor box behind the motor (as much as 120g but varies case by case) until the COG nominated is the static balance point with the wings level - not pitched up or down. The COG nominated results in a plane that needs a little down on the elevator when flying inverted. I am a precision aerobatics flier, not 3D.

@@eddrakes Hello Ed. Kindly thank you for your reply. I’m sport flyer i would say ton crazy 3D. I just got really confused by CG. Also my plane is approx. 700 longer than length mentioned in manual. ( they say 1661 mm mine approximately 1730mm) Also some guys say the factory put CG more forward so i could be on the rear edge or about there of the wing pipe. But i like to follow the manufacturer as i trust they spent some time designing the plane. But really doesn’t sound right adding 200 g of dead weight. My only answer would be the gas engine and tank are heavier than small electric motor and one battery. This is the first time i’m having this issue. Thank you Radek

@eddrakes 2 жыл бұрын

Centre of gravity as marked, over the joiner tube, is good. Since the rudder servo is located mid fuselage length, I had to move some weight further back from the front of the plane. So I put the ESC near the batteries. I am correcting the plane RTF weight to a measured 5.96kg. The battery is 2 x 5S 5000mah 50C --> 10S. I never use the safe mode for the gyro - too controlling. As an experienced, aerobatic pilot I find the gyro in its simplest, "stabilisation" mode is enough for me. Yes, and you are correct, this size is perfect for flying at our field. Thank you for the comment.

@@marianolte8233 Since I fly and adjust weight to get the result required in the air, I have no CG marker in the plane. This is all subject to your flying style of course. I prefer precision aerobatics - large manouvres - resulting in a more forward CG location. Additionally, I employ a stabiliser which not only stops the annoying wobbles caused by wind, but also compensates for problems with CG. In other words you can quite off the correct CG position but lean on the stabiliser to keep your plane level! Similarly, a stabiliser obviates problems with all the trims caused by badly centering servos. Go to this URL to calculate your CG - fwcg.3dzone.dk/

Hi Ed thank you for the unboxing video... I'm just in the process of building mine at the moment after owning 2 67in Slicks I've added lots of reinforcement to the small motorbox essentially making it strong enough if the prop hits the ground the PROP breaks! Instead of it ripping these extremely weak motor boxes out!!!...I added carbon fiber 4mm X 4mm rods along all 4 sides/corners and drilled holes through main motorbox firewall and glued these in place plus I also added the Balsa fillets that come with the kit down the inside corners and then glued/screwed into the ends of these to the main firewall to hold it in..plus I also made another piece of plywood and glued this onto the front face...these are weak too!! Great planes but this little motor box lets them down IMHO. What made you choose that particular Dualsky motor? I run the Dualsky GA2000R with an hobbywing 120A and it pulls 135A on a 18 x 10 prop...I love the motor 25cc petrol equivalent.

There a lot longer than the Slick 5 inch I've also added some carbon rods to some of the vertical uprights after realising there's NO UPRIGHT VERTICAL Carbon fiber in these planes...and I've had a few tumbles with mine and the internal vertical plywood can break up...

Thank you for all the helpful comments. I may yet add some of the reinforcing you suggest. To go a little more easily on the airframe, and by preference, I fly IMAC and F3A sequences only. So, by comparison with 3D motor box loading, my flying is more gentle. I have had and still have around 20 sport planes in the 20cc to 30cc size range. Check out my Pilot-RC Slick 74" Under The Hood video showing all the equipment installed. Note the motor box is replaced with fully portalised threaded rod supports - very strong. With this motor attachment system the plane sounds solid and authoritative. I have now watched your 67in Slick video - very nice.

3/16th or 4mm Threaded Steel Rod -------------------------------------------------------- This rod should be available from your local hardware store together with the plain nuts, nyloc nuts and washers. The result is a very strong motor mount due to multiple portal framing rigidity. Method: - Drill 4mm(+) holes accurately centred over the cross-hairs lasered into the motor box face. The hole centres should match those of the motor spider. - Dowse the holes in thin CA so as to harden up the area and resist the clamping pressure of the nuts. - Accurately calculate and cut four threaded rods long enough to position the motor with allowance for all fasteners and final adjustment. Make sure the cut ends are chamfer cut/sanded so as not to ruin the nyloc nuts as they are wound on. - The order of parts on one rod starting from inside the motor box is: Nyloc nut, washer, motor box wall, washer, plain nut (including blue thread lock), [outer end] plain nut (including blue thread lock), washer, spider arm, washer and nyloc nut. The final result is a very rigid motor support that makes for a quiet-running power system.
