Declan Posted January 5 Author Share Posted January 5 27 minutes ago, leccyflyer said: The issue doesn't depend on the model being unrestrained and moving, it depends on the operator inadvertently moving their hands through the prop arc - which is more likely from the front of the model. Ahh, ok I can see what you mean. Fair point, the nose section does line up with the prop line! So the risk is on the initial battery install.? Once the batteries are installed the risk is effectively zero if the ESC has armed correctly? I have a throttle cut on my TX which I flick off prior to my timer switch as part of my pre flight routine. I've adopted this while learning to fly helis which are truly frightening IMO.

Declan Posted March 1 Author Share Posted March 1 After a few weeks flying and assembling/repairing other models I finally got some more work done on this build. 2 Quote Link to comment Share on other sites More sharing options...
Declan Posted March 4 Author Share Posted March 4 I've finished forming the main wing control surfaces and started the channel and aileron servo box cutouts. I'm going to stick the wings together and bed the conduit in the wing with Gorilla glue. I'll add the metal bar from an older model into both wings as extra support. The gorilla glue I'm using is basically liquid expanding foam so it will hold everything nicely. 2 Quote Link to comment Share on other sites More sharing options...
Declan Posted March 13 Author Share Posted March 13 I'm trying not to replicate everything here on the main build thread for the Me110 and keeping this as a more detailed build log. The control surfaces are coming on and I'll post an update on those when they're finished. I have been doing some experimenting with covering materials which has delayed them somewhat. My Fw190 build is queued behind this project so I've been testing out a few things on this model. In the meantime I've joined the wings together. I'm using the expanding type of gorilla glue which is very strong and sticks pretty much to everything! I'll be covering the wings with cloth and resin (more about that in my control surfaces post in the near future) so I'll overlap the cloth at the joint for extra strength. I may not need the jointing bandage in this instance as the cloth will be effectively doubled over the joint and should be very strong. I'm also going to place a metal wing spar in the end of both wings that I have from an older disassembled (crashed beyond repair) model. 1 Quote Link to comment Share on other sites More sharing options...
RICHARD WILLS Posted March 13 Share Posted March 13 looking good Declan . Dont forget to top hinge the control surfaces . That way it looks neat from the top . The flaps on mine were cut away at quite an angle so that when in the down position with the hinges at the top , the flap did not foul on the rest of the wing . I think you are right about just glassing twice in the middle . A bandage on top may well be overkill . I wouldnt use a rod as a brace in foam wings as it will simply compress the foam surrounding it . If you feel you need extra dihedral support , just add a vertical ply web . The ply has a large gluing area and will all grab the obechi skin top and bottom . I normally just saw through with a hacksaw blade , then smear the ply brace with some of your "golden " Gorilla glue before sinking into place . Very difficult to break or dislodge a vertical ply web . I also agree with your use of the above treacle for wing joining , bloody marvellous !

Declan Posted March 16 Author Share Posted March 16 Ok, I'll drop the wing spar if it's going to cause issues with compression of the foam. My plan was to hinge the ailerons on the top as you've suggested with the cutaway on the bottom to keep the top neat. My plan for the flaps was no cutaway and a bottom hinge. I figured there would only be a large gap when deployed. The flaps are finished so I'll have to stick with what I've done. The fuselage is also nearing completion so I hope to have photos of the primed parts by the end of next week. The fuselage has been clothed with glass cloth and EzeKote. It's a very strong construction now! The model is looking like it could be a very good everyday flyer resistant to hangar and transport rash. I did buy the Dynam Me109 as a compliment to this build, hoping to have a mini Geschwader. 2 Quote Link to comment Share on other sites More sharing options...
Declan Posted April 7 Author Share Posted April 7 Been a bit busy with other models and flying lately but finally got around to pushing this model along a bit further. Latest picture of where I'm at. The control surfaces and the tail parts are all finished and primed ready for assembly. The fuselage is built but needs a bit of more work on the preparation front. I was experimenting with covering so this has led to some errors in the finishing. I've corrected them and will sand them down ready for another coat of primer. I'm now at the setting up the attachment of the wing to the fuselage stage which is a good milestone. Some thin plywood will be added to the central part of the wing to support the mounting bolts and I will shape a central fuselage on the bottom of the wing. A plastic conduit has been inserted into the wing for the wiring as most of the electrics will be on the wing with only the servos for the elevators and rudder in the fuselage as suggested by other builders. I've got the bricks on the servo boxes for the ailerons to keep them flush to the wing surface as everything has been set in place with gorilla glue, great stuff! Once everything has been set I'll fill the channel and sand it flush in preparation for the glassing over. I will be using Delux materials glass cloth and EzeKote resin for the covering. I will also need to offer up the finished ailerons and flaps so that I can shape the wingtips prior to glassing. Looking at the wing on the model it certainly seems like a substantial bit of kit! 1 Quote Link to comment Share on other sites More sharing options...

Declan Posted April 8 Author Share Posted April 8 Filled in the channel above the installed conduit in the wing. I've created a fixing panel with dowels to go into the fuselage with a ply profile at the front to match the fuselage. Experimenting with a wood shaving (from the wingtips) and gorilla glue mix to fill in the void behind the ply. Hopefully the glue will expand as usual and create a lightweight filler in the space. I'll clad this in balsa shaped to match the fuselage and feather it into the middle of the wing. I will need to apply a glass bandage on the joint first for strength. This will be overlapped from both sides with the wing cloth sheeting which I'll do before fixing the engine nacelles for simplicity. The sealed glass wing should be a better fix than the sheeted polystyrene wing core I think. Once I've finished the wing fixing and central area I'll start on the engine nacelles.

Declan Posted April 8 Author Share Posted April 8 Wingtip now shaped and the aileron boxes filled around the edges prior to final sanding before glassing. I'm quite happy with the expansion of my gorilla glue and shavings concoction. It's expanded very nicely to fill the void. I'll remember that for future use. 1 Quote Link to comment Share on other sites More sharing options...
Declan Posted April 10 Author Share Posted April 10 Laid down the fiberglass jointing strip in the middle of the wing prior to shaping the lower fuselage section with balsa. I'll cut out the openings for the wing bolts afterwards and recess these into the formed fuselage. Once this is completed I'll then glass this section overlapping to the wings. Don't think it will break! 1 Quote Link to comment Share on other sites More sharing options...
Declan Posted April 20 Author Share Posted April 20 Central section formed with final filling applied prior to sanding. I'll glass the wings once this has been finished. 1 Quote Link to comment Share on other sites More sharing options...
