maybe I will have to see the plane first, then make a decesion.
I like the idea of velcro. That stuff from HK is super strong!! |

AXN = Bruce SimpsonQuote:
After all, look at all the posts to this thread, I dare say that most are because of the videos and thoughts/help/advice shared by Bruce in his AXN videos. Once word of the AXN got out there...sales and interest really took off. Start with a Sim..then buy an AXN..watch the videos and your flying...and for very little $$$. As of today just look at the number of posts and views on this thread, it's crazy! A testimony to the AXN and Bruce getting the word out... -mike- |

Also, I followed Bruce's guide to the letter, including getting his recommended 6x5e prop and a nice collet adapter. It all went together beautifully, but I did make sure to triple check everything and take my time during the build. Committing to gluing the wings in place made me a bit nervous, but it sure is strong! I had a servo crap out on me before the maiden, so as soon as the new one arrives I'll finally be able to take this thing out. I've gone from a stock NmH Super Cub, to Lipo, to a 480 motor and ailerons, to a T-28 Trojan (still stock), so I'm really looking forward to this plane and it's wide performance envelope between gliding and surprisingly fast. Cheers! |

When it is in there (either horn or servo arm) it needs to be able to fully rotate without coming loose. (some put a tiny drop of CA on the nut but don't get it on the rotating part!!) Then the push rod goes in and is held solid by the grub screw at the correct length to have the surface in the neutral position when the servo is centered. (don't get your surfaces adjusted by the radio trims ... this is for trimming not setting up.) |

I planning to get my axn to fpv saw this post on the other thread seem nice clean build
https://www.rcgroups.com/forums/show...9&postcount=20 but my concern is will it effect the stiffness of the whole structure after it being cut like that? as a belly lander you will need the belly to be tought unless i have a landing skid |

I have a spare Hawk Sky motor (Dynam Speed 400 Brushless), would it be a good or terrible idea to replace my CF motor with this in order to get more power? It's a straight fit.
Here are the specs: --- Size: 28.80mm (Dia.) x 27.00mm (L) (excluding shaft) Weight: 42.8g Shaft: 2.90mm (Dia.) K/V: 1750 Working Current: 1.8 - 13A Battery: 2 to 3 cells Lipo batteries (or equivalent Ni-xx batteries) Motor Test Results: 1. Direct Drive fitted with a 9 x 4 prop and operating of a 7.4V 2 cell Li-po drawing 10.9A current delivered 416 grams/ 14.7 oz thrust 2. Direct Drive fitted with a 8 x 4 prop and operating off a 11.1V 3 cell Li-po drawing 10.5A current draw delivered 515 grams/ 18.2 oz of thrust. --- |

I'll go for 2200kv from rctimer or the turnigy 2200kv for power need bigger esc (40A) but it will be power hungry |

2nd photo shows an FPV "backpack" as devised by Bruce Simpson aka XJet. As you see it is on a flat coroplast base which allows it to be moved from aircraft to aircraft. It is on a foam block cut to shape for the AXN here. It uses the HK 5.8GHz gear and has transmitted to an LCD screen in my workshop, It is waiting for the completion of two cloverleaf antennae before testing in the field. It may be possible to mount it on the flat part of the cockpit, depending on CG. So many projects, so little time! But the keychain cameras are a really easy and cheap way to record video, which can also be easily used on multiple aircraft. |

Whoops!, forgot the photos . No holes cut in the fuse for either keychain or FPV camera, and they can both be moved easily from aircraft to aircraft.

I also did have the rudd/elevator push rods going straight back, not crossing over each other, so I've remedied that too and things are much much smoother. Again, much appreciated! |

I see the latest is two SPWs now and no need for clover leafs. On the base I have a SPW and a Helical. The Helicals are great and do not take long to make.,
How do you go with the camera in that location? I had one there but pointed it down quite a bit so I could get my bearings and got a lot of nose in the screen. |

If you know where you are when flying FPV then the angle but I need a LOT of ground to keep my bearings even though you can tilt your nose down when flying to see where you are.
I only use 2.8mm lenses to get a nice wide view to help see where you are going. https://www.hobbyking.com/hobbyking/s...dProduct=21284 Looks like you have a great FPV camera. I have to put extra weight on the nose of mine as I have the servos outside the body near the rear of the wing like the EasyStar. By doing that there is a massive area in the body. Quote:

A mate had one of those using it as you said and lost video while flying.
Apparently if the camera looses power for an instant you totally lose video until you push the buttons again. Not sure if it was caused because he just used a plug in the video out and it lost connection. Maybe worthwhile wiring it into the camera and not use the video out plug. |
