    Last pics for now. The box has its screws and a test fit of the Power 60. :Sleeping2: Need to add triangle stock and a little epoxy to finish them off... I don't think they will structurally fail....:Cool:

      Last comment for this session. The boxes are over-built. But, I have that latitude since the glow engines with muffler weighed 17.8 ounces without the mount. The Power 60's weigh about 13.4. So I need to make up about 4 ounces on each setup to keep the CG in the range... So with the ESC and wiring and such, it should be very close!!! Good night (morning) all...:P

        You could always add Harry Higleys Hubs. That's what I did on both my Hanger 9 20CC P-47 and F4U. Both use the Power 60 set up. They make several different weights .

            Thanks Mike!!! Always an option... I have plenty of batteries to move around for a good CG too!!! I hope it is not too heavy one way or the other. :Sweating:

              I think itll be a good. And as Mike pointed out you always have the weighted hub option if need be. I feel like this will definitely hit the Mark's you need. One way or another options are nice to have. :Cool:

                If my motors go shooting off into the wild blue... it makes the B-17 harder to fly!!!! :Silly: Thank you bunches!!! Almost done, and then going to mount to the old firewalls....

                  Just found this is the SPAM blocker... This is the reply from Castle Creations on the battery to ESC extension length....

                  Jerry,

                  Max length between the ESC and battery is 12”. Any more than that and you’ll want to add an external capacitor pack to the ESC wires to prevent damage to the onboard capacitors. Here is a link to the cap pack we make. http://www.castlecreations.com/en/cc...ck-011-0002-02

                  Please let me know if you have any other questions. I’m happy to help, and have set up many multi-engine aircraft.

                    So with this information direct from CC, I think the extensions will be just fine. They are under 18 inches (barely), and I have the CC Cap Pac to add to each ESC for the addition lengths... :Cool::Cool::Cool::) Back to work!!

                      These are a few of the pieces for the motor mounting and boxes. The servo screws are for the boxes. 12 on each box, so 48 total.... Then there are the 6/32 x 3/4 inch SHCS, lock washers, and tiny #6 fender washers to mount the Power 60's. I don't have any regular #2 screws for the back of the boxes, so I am having to modify 24 of them by grinding the washer off each one!!! That way they counter-sink and will fit flat against the old firewalls... No wonder my head hurts.... LOL :Silly: So ready to move on from these today...

                            Thank you LB. I appreciate you bro!! LOL Anyway, this worked great.... 20 minutes, instead of waiting two days for more screws to come in... Run the drill one direction and the Dremel the other and you have a mini lathe....

                                No doubt, but it is one of the most important. Atleast it's almost knocked out

                                  After a rest, all of these will be epoxied to the old round firewalls. Then on to servos, and beyond!!! WOOO....

                                          After my beer and taco and hanging out with my little girl, I was worn out. I did some more work to finish the motor boxes and then went to bed... Here they are finished. Lots of other stuff to post, but I will do that tonight!! Hope everyone is having a great day!!! Happy Birthday BTX!!! :Party::Cake::Balloon::Drinks: That ugly firewall will be beautiful next time around!!! :pop
