Adrian Smith 1 Posted November 7, 2018 Author Share Posted November 7, 2018 I just about had time to adjust the throw on the elevators. The low rate is suggested at 20 degrees, but I am going to start off at 25 degrees +/- I will do the ailerons at the next workshop visit.

Rich too Posted November 8, 2018 Share Posted November 8, 2018 👍 that’s my favourite stage 😉 Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Yes, Rich it means the maiden flight is not too far away. When I have done the throws I need to do some work on the motor end though. I have a little bit of soldering to do by way of making some series leads when I have established where all the batteries are going. Just fiddly bits really.

Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 I thought as I had levelled the fuselage to set the elevators I might as well check the wing incidences. As it's an aerobatic ship I imagine they will be 0 degs. Everything needs to be just right. Lets see. Yup seems fine. As a starting point I am setting the ailerons at 20degs +/-.

Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Now on to the rudder. I have set this at 30degs +/- Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Time to do a bit of soldering. I made a series connector with 10 gauge wire and soldered an EC5 connector to the already formed wires from the ESC. All put together. All ready for the 12S power lipos.

Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Moving on to the button head screws that are used for attaching the cowl externally and the cockpit hatch. They are white headed so I decided to invest in some blue paint from the local auto shop thereby blending them in with the blue covering. Should be ok so I will fit them when dry.

Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Last job of the day is to attach the U/C collars using clear silicone sealant and taping them in place to dry. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted November 8, 2018 Share Posted November 8, 2018 Looking good Adrian, nice bold colours, should show up well in flight. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 8, 2018 Author Share Posted November 8, 2018 Thanks, John. With my eyesight I need colours I can see! This is the reason why I fly the bigger models, that and they fly better in windy conditions. There is still a lot of odd jobs to be done on her and I owe it to the project to take good care with it.

Adrian Smith 1 Posted November 9, 2018 Author Share Posted November 9, 2018 Slow progress today as I am systematically thread locking all bolts & nuts. The button screws seem to match the covering satisfactorily. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 9, 2018 Author Share Posted November 9, 2018 I decided to programme the Opto ESC using my Dualsky card. The only setting I altered was to change the timing to "High" as this is suggested for motors with an excess of 20 poles which my Dualsky motor has. 28 I think. The" medium" cutoff voltage is 3.2volts per cell which I left as per the original setting.

Adrian Smith 1 Posted November 9, 2018 Author Share Posted November 9, 2018 While I was up the motor end I decided to check the motor direction and found it to be correct so I tidied up the wiring and added an additional piece of heat shrink tube per wire before nylon tying them together.

Adrian Smith 1 Posted November 12, 2018 Author Share Posted November 12, 2018 Time to press on a bit. I have made the wiring a little more tidy and located the RX and HV switch. I have not yet settled on where the RX lipo will go. Time will tell when I assess the CoG. I also put some rubber grommets in the cowl and hatch screws to help counter any vibration.

Adrian Smith 1 Posted November 12, 2018 Author Share Posted November 12, 2018 I attached battery velcro strips for whole length of the fuselage beyond the wing tube to give me latitude to position the batteries. Now to the CoG. The manual suggests that the CoG is aligned with the wing tube and that the aircraft is hung by the tube with main wings and hatch added. Hmmm .... this is going to be fun!

Adrian Smith 1 Posted November 12, 2018 Author Share Posted November 12, 2018 Not that it means anything significant, but the fuselage without the wings is fairly well in balance. I don't have CF spinner yet so I left the prop covers on for a little bit of extra weight to allow for this. Using two 5000 mAh 6s lipos positioned bang up against the wing tube + the RX battery placed close to rudder servo the result is about right. However, using a couple of 6000 mAh in the same position, which I fly with too, along with the same position for the RX battery, the nose dips noticeably.

Adrian Smith 1 Posted November 12, 2018 Author Share Posted November 12, 2018 So I have the problem of making a tray of some sort for the RX battery to allow adjustment depending on the power packs' capacity I am using at the time. Gonna have to think how to do that. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 12, 2018 Author Share Posted November 12, 2018 I have ordered this 4.5" spinner from HobbyKing. **LINK** The observant of you will notice it's the wrong colour! I have a can of matching blue paint to change all that after I have cut the propeller slots. Keep me busy for a day or two Quote Link to comment Share on other sites More sharing options...
Rich too Posted November 13, 2018 Share Posted November 13, 2018 Well done Adrian, not far from the maiden now. I don’t suppose those batteries will fit sideways against the wing tube? Not sure the fuselage is wide enough... Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 13, 2018 Author Share Posted November 13, 2018 I did have a look Rich, but the 6A lipos are quite long wouldn't fit across despite the spacious airframe. After giving it some thought I am going to put the RX battery beyond the rudder servo in a tray well out of the way of everything. It is no problem to add a longer lead from the switch to RX battery. I will just position the power packs a little bit further forward to compensate for the shift in weight distribution. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 13, 2018 Author Share Posted November 13, 2018 The spinner turned up today from HK. Very quick turnaround. Quite on monster! Holding it against the cowl i am not sure I am going to need to spray it blue. The orange blends in quite well. I will see. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted November 13, 2018 Author Share Posted November 13, 2018 A bit stymied for the moment as I require at least a 120 mm M5 cap screw for the spinner to attach to the prop shaft's pre drilled hole. I only had 100 mm in my spares box. So step up Model Fixings. They sell 130 mm bolts in pairs which will do just fine. I decided as I am short of 5 minute epoxy I would put that on the order too. A few clicks and its done. In the meantime I can drill the spinner back plate for the motor bolts. I used the motor propeller plate as the template. All drilled and fitted for accuracy. The prop slots will be done when I receive the spinner bolts from MF in the post.

Adrian Smith 1 Posted November 13, 2018 Author Share Posted November 13, 2018 I decided after some thought to start on the RX battery platform. I used liteply for this job and balsa reinforcing quadrant. I drill some lightening holes. Not sure if it will make any difference. All glued in with 30 minute epoxy. Decided to finish off with some black enamel and when this is dry I will attach the velcro strip and straps. Quote Link to comment Share on other sites More sharing options...
Rich too Posted November 13, 2018 Share Posted November 13, 2018 You’re right, that orange looks a good match. Quote Link to comment Share on other sites More sharing options...
