    I think on mine, the cowl next to the firewall is a bit narrower (curls inward). Can you tell if the front edge of the motor is touching the cowl, preventing it from seating against the firewall. Another consideration is that when they glued the firewall onto the nose, they over-did the glue and you've got a bead of it going around the inside circumference of the firewall. This bead may be hindering the full seating of the motor.

      Both good points...It doesn't seem to be too narrow for the front edge of the motor...I can get it to spin freely when one or two screws are secure. It's when I try to secure all 4 then it starts wobbling again. I may have to try longer screws. I definitely need a different pair of eyes taking a look, and he's a Boeing engineer so that is favorable, lol.

        Well xviper if I could capture my experiences trying to get the motor mounted it would make for quite the comedy show. So after wracking my brain initially, I finally realized the screws I was using (stock from the plane) were too small. No wonder the motor didn't settle! Oy vay. So I tried the screws that came with the Power 32 and they were too short because they are meant for an external X mount. So I went to the local hardware store to find the same size diameter but longer (8-32 - 1/2") and those proved to be too long. Sigh. So I took my dremel and eye-balled cutting them down to the approx. size I needed. So as I stand before you today, I have TWO screws tightened. The motor seems fine. Doesn't wobble. Solid. If I try to add the other two suddenly the motor stops turning. Where is my cursing emoji?

        To add to my poop show, the ESC the guy bought for it has the wrong size bullet connectors. The P32 takes 3.5mm and the ESC he bought for it (80A which is overkill) looks like 3.6 or 3.8mm bullets. I was at least able to wrap Gorilla Tape around the connectors so I could bind the plane and get the servos working which thankfully they were working fine. Not enough connection to spin the prop so here I wait for another week or two to buy the proper ESC for it. I am looking at the ZTW 65A with XT60 connector. Has 3.5mm connectors.

        So here's a "so close but so far away" shot of her thus far. ONE DAY I will be able to report a maiden I swear!

          You may be a bald man when you're finished. But so far, it looks real purdy. I don't think I recall having quite the time that you've experienced. May the rest of it go smoothly for you.

            Well my friend you're a little late on the bald diagnosis...If I had any to pull out it would be gone!

              xviper well I am happy to report the enigma of the motor mount has been solved. I knew a certain Boeing engineer's eyes would be just what the doctor ordered. It really wasn't anything major...In fact all it really involved was dremeling out the center hole and one of the screw holes a bit more to free it up. Now the motor is mounted, prop/spinner installed. All that's left to do now is snag the ZTW 65A ESC that will fit the motor, get the CG dialed and take her for her rightful place in the skies. I want to once again thank you for all of your help it's been definitely appreciated. The next post from me hopefully is the maiden video.

                Happy to have been of some help. Looking forward to the video and your impressions. When you do maiden, the first landing may show you just how well this thing hangs when about 15 feet off the deck, especially going into even a slight breeze. Plan a long straight final and don’t be too surprised if it just doesn’t want to come down that last few feet. Don’t worry if you have to go around and try again. I flew mine last weekend and it took me about 3 go rounds before it landed. It kept just floating past me at about 10 feet up.

                  I've heard that very thing...I have a spot picked out with plenty of open grass fields...Should be perfect!

                    Okay my ZTW 65A ESC and Admiral 3000 4S arrived today and all went well. The only thing left to do is CG and throws and she’s ready for launch. The plan is Maiden this Saturday. I will put my RunCam2 on her somewhere to record the flight.

                      xviper maiden success. Beautiful day to maiden, found a nice open grass field. She needed several clicks of down and was a bit tail heavy. I have the CG marked at the manufacturer's location. I had to add a couple ounces of ballast and looks like I will need another couple ounces or so. But she flew beautifully and didn't want to come down, lol. She just wants to keep soaring. I found adding a little bit of power actually helped on the landing sequence. Looking forward to really getting her specked out at some point. Very pleased!

                        Bravo!!! Beautiful plane, beautiful scenery. I think they are all tail heavy when converted to electric. The amount of weight I had to add to the nose was ridiculous. Once you get it weighted right, it'll land almost all by itself (eventually).

                          Thanks! Yeah I don't think adding that bell crank helped matters weight-wise...Oh well, whatever it takes. I added two more ounces...Hopefully that is enough. I'll try again tomorrow.

                            The alternative to the bellcrank was to install a slim wing servo in the tail and I think one of those would be heavier.

                              True...Good news is that I don't think it requires too much more nose weight to be in the pocket. Will report later today.

                                Beautiful glider Aros. Thanks to you and Viper for the follow along build. Very enjoyable. I wish I had one.....

                                  Thank you Grantham Kid she is a beauty for sure. One I may struggle with trying to get back down to Terra Firma at times.

                                  Looking forward to eventually re-skinning her to show off the ribbing detail of the wings and tail like this:

                                    Another nice flight today. Now that I have enough ballast in the nose she is a dream.

                                      Just curious what battery are you using and how much ballast did you add? Where did you put it?

                                        I am using the Admiral 4S 3000 battery. On average I am putting maybe 500mAh back in the pack after a 30 minute flight. Not sure on the final ounce count for the ballast.I will tally it up and let you know.

                                        • I started off using a 3000mah, 3s Graphene and I couldn't completely close the canopy, so after a few flights, I changed to a 2800mah, 3s Zippy, which is about the size and weight of a 2200mah, 3s, Turnigy Heavy Duty. With this, I'm able to move it right behind the motor, so no extra weight needed. I built it to run on 4s, but there was no way it would fit under the canopy. Having been flying it on 3s, I feel I don't really need 4s, but one day, I'll give it a try with one of my 1800mah, 4s Graphenes.
                                          I have the return home module sticking into the battery compartment but even without that, I'm amazed you can get a 3.0, 4s in there.
