      Winter in Chicago - probably be a while before flying season starts

          I've heard talk of a clear canopy, Motion list one from a different model for some reason, has anyone knowledge of the listed canopy and offered it up to see if it could be fitted/chopped up to fit etc.

          Looking at the Lightning canopy it is essentially hollow, there are good sized painted frames where the glass would be. I've been looking at various clear plastic food/drink containers. I think it would be a straight forward minor "modelling" job to let some clear plastic into the foam for most of them at least. I've got a 2nd Lightning en-route from Aliexpress so will have a go once Christmas/New Year is fully out of the way.

          Did I see 3D rockets for it.

            kallend has made 3D rocket prints I believe. Back in the thread somewhere. The canopy is very thin foam and the open space under it with no cockpit floor or pilot is useful. A clear canopy may be a big job. I think I will put clear paint over the foam and or change the color a bit to make it different than the silver fuselage.

                Yeah man! I am always amazed at how some modelers can produce so much cool stuff. I'm on the fence about printers only because it would be another hobby! But if I had one I would be printing up A LOT of your designs, cheers!

                  I've added a few more bits and pieces for the Lightning to my Thingiverse collection:

                  These are missiles scaled for the Freewing 64mm BAC Lightning.It is in two parts with a joiner to minimize supports needed for the "wings" when printing. The front ends come in two versions:The tab on the side needs to be glued in a slot cut in the fuselage of the Lightning.A socket (included) is glued in place and the firestreak2 or RedTop2 front ends have tabs for insertion in the socket. This makes the missiles easily removable and interchangable.There is also a filler piece for the top of the wing in case you do the "aileron mod" to put the servo arm and aileron horn on the underside of the wing. Also a "shield" to go over the servo arm to help prevent damage in grass landings if you've done the aileron mod. It's handed, so you'll need to make left and right versions.If you're willing to do a LOT of work and fiddle around, there is also a mount for an "afterburner" lamp. It does not attach to the motor, it is glued in the tailpipe right behind the fan unit so the mount is aligned with the motor but about 1mm behind it.

                    Decided to have a pop at a clear canopy mod. Very sharp knife, Ferrero Rocher 300g clear lid, ( other sickly sweet sweeties/candy are available) and a slightly blue green mineral water bottle.

                    Clear lid is about 1mm thick for front screen and top piece, thin bottle for sides.

                    So, cut right through the foam leaving a very small silver margin around the edge, then cut slightly outside this into the black frame area, about 1.5mm and to a depth of about 1.5mm to create a small rebate for the "glass". I did start to colour the cut edges with a black sharpie but it dried up so more work later. Use the removed piece and masking tape to create a template to stick to the plastic for cutting.

                    I've kept the masking tape for the necessary repaint, going to refinish the black areas in matt black before a coat of Polycrylic semi gloss. I may reinforce the areas around the windows with carbon fibre thread or very thin bar.

                    Plan is to glue in a cockpit floor 0.8mm - 1/64 ply and have ordered to pilot motion list with the plane.

                      Nice work. Just shows what can be done with a little ingenuity and some modelling skills.

                        I see that Aros just started the Official 64mm BAC Lightning thread….

It does slow it down and add a lot of drag inflight though. But with all that power it is still a good performer. I'll bet it would be fine on grass.
                          How did your friend make out balancing his model with wheels? I’ve mounted the wheels and with a 2200 4S pushed all the wayback, my Lightning is nose heavy.

                            I fitted the landing gear but made it removable,( its a few pages back) Tried various batteries from 1800 to 2200 4s pushed right back, always nose heavy. One of mine came with the Freewing gyro pre-installed I added a AR620 obviously made it worse, pulled the gyro and extra cables and swapped the AR620 for a AR630, yes still nose heavy. I tried a few weights at the back end and it needs approx 20g - 3/4oz

                              Thanks Wrongun. Guessing steering servo and nose wheel together require the counter weight. Regret I glued the nose wheel in before I found this thread, but good to know others are having the same experience with the nose wheel. Will add ballast (cringe!) and report maiden.

                                ESC Cooling Vents?
                                With a 2200 4S pushed all the way back (seems to be necessary if wheels mounted) there isn’t much space for air to get past the battery to cool the ESC. Anyone else concerned or have a solution?

                                  I put an inrunner EDF unit and "afterburmer" in mine, no CG problems.

                                    Thanks for all your suggestions John. Are you using landing gear and still able to balance without counterweight?

                                        I’ll be more careful how I word my questions in the future, but thank-you for both answers.

                                          Is anybody actually flying this model successfully WITH landing gear?
