So...... can't change fuel tank in my Valiant can't fit engine to my Ruckus can't put tissue on the laminating film covering of my SE5. Hmm, nothing much left! Try using eze dope for putting the tissue onto laminate, doesn’t smell, and is user friendly. Quote Link to comment Share on other sites More sharing options...
johno342 Posted January 26, 2023 Share Posted January 26, 2023 This is my first low wing build, and I would appreciate a little help on the electrical fitting out. The cockpit floor and cockpit itself mean all the fitting out must be done from below, I assume A few pictures showing the ESC, RX and elevator / rudder servos would be much appreciated Will this fly anything like the Spacewalker that I am currently enjoying practicing with on RF 9.5 ?

kc Posted January 26, 2023 Share Posted January 26, 2023 On a low wing model with the wing removed there is access to the servo area. Servos can be reached easily to fit clevis to servo horn. F2 has a slot which would enable the ESC lead to reach the Rx. F4 also has a hole for wires. On all my model I like to have a removeable hatch under the Lipo tray so the ESC lives there. Hatch has slots cut in and a ply tab with a screw goes into u/c plate to secure. In the Houndog there are spaces at side of Lipo tray which seems enough to allow the connectors to pass up towards the Lipo. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 26, 2023 Author Share Posted January 26, 2023 KC has got it right. Tomorrow I will see about some pictures. AS for flying,it can be quite steady and smooth with graceful aerobatics or you can increase the throws for more positive aerobatics. IT will not turn round and bite you.

johno342 Posted January 26, 2023 Share Posted January 26, 2023 I look forward to seeing the pictures, thanks Peter. Looking forward even more to flying it! I passed my 'A' test back in October 2022, and am beginning to get a little frustrated with my Discovery trainer. The plan is to use Hound Dog to train up with a view to taking the 'B' test sometime in 2023 🤔 Quote Link to comment Share on other sites More sharing options...

johno342 Posted January 27, 2023 Share Posted January 27, 2023 Thanks for that Peter - as I expected, the servos are mounted upside down - the plan shows them the other way up which didn't make sense to me! I have installed the snakes using the laser cut guide holes and that strongly suggested that I mount the servos upside down and a little behind F4 Just like in your picture 🙂 Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 27, 2023 Author Share Posted January 27, 2023 I don't think I even drew the servo outlines on my original plan. Just checked. No I didn't. Quote Link to comment Share on other sites More sharing options...

It was bought without a receiver and although I fitted a FrSky S8R, I never used the gyro facilities whilst training. I had high / medium / low rates set up, but my instructor was very keen that I should learn to fly 'properly', and we only ever used high rates. Since I passed the test, I have had a play with them, however! Having seen several other people bin their Discoveries, I like having the option of an 'automatic level mode' switch.

GrumpyGnome Posted January 27, 2023 Share Posted January 27, 2023 I'm with your instructor. Hound Dog should be a nice, manageable step up. And much more fun! Quote Link to comment Share on other sites More sharing options...
johno342 Posted January 30, 2023 Share Posted January 30, 2023 I am looking at assembling the engine cowling, and it caused me to wonder about any thrust line offsets. Do you fly Hound Dog with any specific thrust line offsets or should it be flight trimmed starting from 0,0 ? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 30, 2023 Author Share Posted January 30, 2023 I NEVER USE OFFSET THRUST LINES. Quote Link to comment Share on other sites More sharing options...
Solly Posted January 30, 2023 Share Posted January 30, 2023 Me neither. I always achieve straight and level flight by using rudder and elevator trim, if necessary mixed to the throttle control. I suspect engine thrust offsets hark back to free flight days. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted January 30, 2023 Author Share Posted January 30, 2023 The only time my models swing on take off is due to torque. A dab of rudder cures that. Some time ago I watched film of American fighters taking off from a carrier. What was really noticeable was the big boot full of right rudder being applied as they started their roll.

tspr12 Posted January 30, 2023 Share Posted January 30, 2023 Hi everybody Hi Peter I also started building a dog. I'm already quite advanced. Yesterday he installed the servos according to the drawing and I found out that the snakes go completely differently. Only today I found out on the forum that they should be installed the other way around. I have a topic to think about now. I work in mm (so from Slovakia) and the front landing gear is made of 8SWG wire which according to: https://www.justfreetools.com/en/swg--to-mm-calculator the diameter of the wire is 4 mm. It's true? It seems too thick a wire to me. My last topic is the dowel in the wing. What exactly is that? How is it mounted? Could I see a photo? Well thank you Josef Quote Link to comment Share on other sites More sharing options...
kc Posted January 30, 2023 Share Posted January 30, 2023 (edited) 4mm ( 8SWG ) piano wire is normal for this size model . Note that SWG Standard Wire Gauge is not the same as American Wire Gage AWG it's about 1 size different. ( we spell it Gauge while the Americans say Gage ) Rib R1 has a slot to take the dowel and is reinforced either side by R2. Dowel is glued into wing and slides into the hole in F3 to locate wing when assembling at the field. Dowel is commonly birch or beech wood supplied in various sizes of round rod as used in carpentry joints etc. Easy to buy in UK but no doubt any hardwood could be used, could even be square section if the hole in F3 is reshaped. It looks to me as if you will have to saw the servo bearers off - easier than removing the glue. It seems it's the draughtsman's fault and not Peter's fault!

Peter Miller Posted January 30, 2023 Author Share Posted January 30, 2023 Sorry. I did check the plans before publication but never thought of looking at the servo location. I NEVER would put them that way up under a cockpit floor. Yes R-1 has slots in it when they are joined the slots make a hole to glue the dowel in. It works if you use plenty of glue. As Kc says 8 SWG is 4.1 mm piano wire and even that can be bent in a heavy landing. As Kc says,cut the servo bearers off and add new ones or you could just remove servos and glue extra wood on the open side of the bearers. Sorry about all the hassle. Hound dog was built in the lock down and my mind wasn't working too well...Still doesn't Quote Link to comment Share on other sites More sharing options...
tspr12 Posted January 30, 2023 Share Posted January 30, 2023 Thanks for the answers! The size of the wire for the landing gear is now completely clear to me. I also understood the dowel in wing theme. We simply call it a wooden peg. It can be bought, but I also have a lathe, so I will make it. I decided to turn the servos and replace the circular rod with a lever. Access to the servers will be without problems. Thanks everyone for your help Jozef Quote Link to comment Share on other sites More sharing options...

johno342 Posted February 1, 2023 Share Posted February 1, 2023 Hi Peter, I wonder if you would be kind enough to post a couple of pictures of the cowl, showing both the interior and exterior, as I am not sure how best to fit the plastic air scoops without reducing the integrity of the cowl too much Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 1, 2023 Author Share Posted February 1, 2023 The air scoops are just stuck on the outside of the cowl. The holes are just scooped through the side of the cowl. I use a bit of sharpened 1/2" brass tube myself but if you do not have that perhaps an apple corer from the kitchen would work OK. Failing that drill holes and open them up with files. Holes about 1/2" roughly round will be fine. My holes are fairly crudely chopped out. As you can see one scoop,the lower one has come off, Quote Link to comment Share on other sites More sharing options...
johno342 Posted February 1, 2023 Share Posted February 1, 2023 Thanks for that. I was thinking of just drilling a hole under each, so will go with your 1/2" suggestion Quote Link to comment Share on other sites More sharing options...
