    Hi All,

    I Happy to report that I FINALLY started the build on my Gilmore. My situation may have been just a tad different from yours. I ordered the kit from Motion RC and a UMS 5 75 from CH Ignitions, both were sent to my home in Florida. Arrangements were made for a friend to take the engine and other small bits and a courier to transport the kit to Kingston, Jamaica. Don’t ask why I didn’t ship directly to Jamaica, just know it’s all about cost avoidance.

    Anyway, I’ve been busy building away since Friday evening. Must say thanks to all those who have built and shared their experience here. You’ve been of tremendous help.

    Progress to date:-
    • Landing Gear(main and tail) and wheels installed
    • Ailerons, control horns, push rods and servos installed
    • Horizontal stabiliser, elevators, control horns, pushrods and servos installed
    • Rudder, control horn, push rod and servo installed.
    So far I’ve come across two challenges:-
    • The cowl will not slip over the cowl ring. Did you guys experience the same issue? How was it addressed? I’m thinking to sand the ring until the cowl slides over.
    • The UMS 5 75 mounting template does not line up on the engine box without interfacing with the RHS lower tab. I’m thinking I may need to modify the engine box or build a new one.
    Sharing a few pictures of the progress.

    Will provide updates in the week.

      Just took another look at DJMoose’s last video. Pity I didn’t think to review while in the middle of the build.

      I will try again later this evening or tomorrow and report.

        DaleD The cowl is a bit tricky. As I mentioned in post #31, it goes on much easier if the front edge of the cowl mount ring, is sanded slightly rounded vs square. Then put the cowl on at an angle starting with the top. Slide it well past the ring at the top and work it down carefully from there. The gap in the ring at the bottom will allow it to distort a bit and slide onto the ring.

        That engine is going to look great inside the cowl.

            Such a cool plane! We all tend to forget the wonderful Golden Age airplanes, great to see they're being modeled!

              I agree completely Gman! Most modes of transportation from that time period have that "looks like it's going fast sitting still" look. Trains, cars, boats, and planes all had that iconic streamline look.
              Black Horse did a nice job producing the Wedell-Williams Model 44 in the Red Lion skin. So many models of this plane look clunky. This one is a pleasure to look at in the air and on the ground.

                Since resolving the issue with installing the cowl, the next focus was getting the engine mounted. After exploring the various options(modify engine box or rebuild new engine box) and talking with Adrian at CH-Ignitions, the decision was made to modify the mounting plate on the UMS 5 75cc engine. The modification was successfully completed and the engine installed.

                Can someone please check and share the distance from the front of the cowl to the cowl ring with the cowl installed? The cowl that came with my kit has what appears to be only one small dimple unlike the three as indicated in the manual. I wish to be certain this is the correct location for the mounting screws. See below picture.

                With the cowl positioned as per the single small dimple, it would appear that I will need to move the engine forward about 1.5 inches for the prop to clear the front of the cowl. Has anyone modified their cowl any by cutting out a bit by the leading edge of the wings?

                Sharing a few pictures below.

                  This engine looks GREAT on without the cowl. Certainly has me thinking 🤔

                    It's a beautiful engine, no doubt, but I vote cowl on.

                    Meanwhile, I'd love a look under the hood to see battery/receiver/tank layout and know how you balanced the plane to offset the weight of that machine.

                      I’m inclined to agree, will be leaving the cowl on.

                      I will share pictures when I situate all the internal components and establish CG.

                        First time for me posting any pictures here...

                        I am about 90% complete with this build. I am running an EME 70cc Twin with the auto-start.
                        I had to move all the radio gear back to assist with the CG but I have not completed the final balance yet.

                        Bonding all of the blisters on the will be, ummm, a good time, so I have left this challenge till last.

                          mechwizz Thanks for sharing photos of your setup! Nice powerplant, and a clean install, too. Very neat.

                          For anyone else who loves this big beautiful doll, we've got one on sale in the Open Box section. It shows as "Out of Stock" now, but we'll be adding it into stock at some point over the next several hours, along with many others. Huge discount for a small hole.

                            Thanks for the heads up. Will MRC supply the correct covering to patch the hole? Or, will the new owner need to improvise?

                            Thanks

                              Your engine/auto-start combo appears to be similar in weight to my UMS 5 75cc. I note, with the exception of the fuel tank, you’ve place most items in an aft position. I will most likely follow your install as a guide. Should be able to provide comparative notes in the coming week.

                              All the best with your build, please continue to share progress.

                                Thanks for these helpful photos. Let us know how the balancing goes. Meanwhile, I'm looking at the suggested throws. Are they pretty much accurate? 10 mm on the elevator (12 mm high rates) doesn't seem like a lot of throw for a plane this size.

                                  I’ve read post here which suggest the low rates are a bit on the mushy side.

                                  At least one person has used the suggested low rate as their low rate, the suggested high rate as their mid rate and an increase of 30% on the suggested high rate as their high rate.

                                  I think that’s how I will set up my Gilmore.

                                    Yes this is what I did with my Gilmore. The extra (+30%) rudder and ailerons are nice. The book high rate elevator is perfect for flying, but having the extra (+30%) elevator helps for keeping the tail down on taxi and roll out for landing.

                                        Regular wood glue for the canopy? I assume nobody used canopy screws, right? Or would a clear glue like Goop be better?
