Re: Extreme Flight 78" Extra 300 Build
Here are some pictures of the motor mount I made for an outrunner setup.
Extension made from aluminum tubing wrapped in carbon fiber, 8-32 bolts 3" long, aluminum inserts to keep bolts from moving around, washers to spread the load. Total weight for the motor mount, is 1.99 oz plus blind nuts. |

Re: Extreme Flight 78" Extra 300 Build
A couple of things I noticed while building this kit:
The directions say to use an offset arm on the rudder servo, but when you install the control horn on the rudder, it lines up with the hinge line, so a straight arm on the rudder servo works great. The control horns for the rudder have an indent on one side to serve as a stop, and if you push that against the rudder like I did, one side of the control horn will be 1/16" longer, causing deflection of the rudder to one side to tighten the cables and deflection to the other side to loosen the cables. Overall the design and quality of this ARF is exceptional. Can't wait to fly this thing. |

Here is another motor mount idea. This one was done by Tim Attaway, with birch dowels.

Re: Extreme Flight 78" Extra 300 Build
Thanks for posting the pictures. Nice job on the motor mounts Pedro, and Tim. Out-runners are sure easier to mount than in-runners. My motor should be mounted by end of the day tomorrow.
It looks like both of you will be flying before me. I'm still waiting for my servo arms. UPS says they won't be here until the 17th, so I should be ready to maiden the 18th. I guess I'll just have to fly one of yours in the mean time. LOL! |

Re: Extreme Flight 78" Extra 300 Build
I ordered from XXXX on the morning of the 9th, I asked for the USPS Priority Shipping instead of UPS. I got a tracking number saying they shipped UPS ground, the package is still in Florida as of today, with a scheduled delivery date of the 17th. 8 days to get a small package, not so good on the shipping by XXXX if you ask me.
I will still be there Wednesday for your maiden though! |

Re: Extreme Flight 78" Extra 300 Build
While I was at Pedro's I raided his bins for the parts I need to finish the plane. I now think I have everything, and won't have to wait for UPS on the 17th. If all goes well, I may get this bird finished tomorrow.
Thanks Pedro, I owe you! The third, and final storm is scheduled to come through San Diego tomorrow. After that, the tradition warm sunny days we are used to will return for the next couple of weeks. Since our electric field at Sea World has a dirt runway, we'll give it a couple of sunny days to dry out. We are planning for a group maiden Wednesday morning. There should be at least 3, and possibly 4 of the 78" Extras ready to go by then. Two will have the Scorpion out-runners, one will have the stock Torque setup from EF, and mine will have the Neu in-runner. This should make for some interesting comparisons, and maybe give you guys who are considering getting one of these helpful information when choosing your power package. OK, I'm going to the "fancy eating table" to install my servos. More pictures coming soon! |

Re: Extreme Flight 78" Extra 300 Build
The field is actually in San Diego's Mission Bay Park a very scenic location. The field adjoins Sea World, which is just to the West. It is a great site, especially in the Summer when we are kept cool by wind coming right off the water. It is half way between my home and office, only about 3 miles from each. Easy to sneak away for a couple of quick flights during the week. By agreement with the City, it is an electric power only field so that the noise doesn't disturb the beach crowd.
Link to club's home page, take a look at some of the news letters (Peak Charge) for pictures and map to the site: http://sefsd.org/ |

Re: Extreme Flight 78" Extra 300 Build
I'll bring my video camera to the field on Wednesday. Maybe someone with a steady hand can get some footage of a little formation flying
Glad to hear you'll make Wednesday Steve. See you at Sea World. Pedro. |
