Re: Starmax A-10 twin 64mm EDF Forgot to mention, motors are only held in with 2 screws (not 4). First thing, take the fan off and add 2 more motor screws. This may prevent premature fan and mount failure. Cheers |

Re: Starmax A-10 twin 64mm EDF Found 65mm fans on eb*y for $4 each and bought four. They are a perfect match for the starmax fan. Discovered cracked plastic motor mount allowing the blades to hit the shroud. Changing the fan shroud fixed the problem. |

Re: Starmax A-10 twin 64mm EDF After about 20 flights one of the fans blew up for no apparent reson. The individual blades flew off the center dome lodging into the foam cowl (much like my SU34 did after 30-40 flights)! Now I'm searching for spares... I'll keep you posted if a solution is found.

Re: Starmax A-10 twin 64mm EDF Were in Milton do you take it I live here to and I'm having a problem getting my jets in the air due to lack of runway |

Re: Starmax A-10 twin 64mm EDF Finally got around to applying the waterslide decals as supplied in the kit. What a nice product. I put Modge Podge (basically watered down white glue) on the surfaces where the decals were to be applied to help adhesion. Once dry decals put on. Later I watered down the modge podge and painted the entire model to make the surface sheen even. The decals look and stick fantastic. The only extras added were a pilot and a photo A-10 instrument panel printed on my computer (downloaded thanks to google images). The wing has been stiffened with a thin aluminum channel glued on the underside of the center section. Cut into the wing with a razor saw (but not through upper surface). A little grey paint was added to finish the underside and exposed servos. It flies fantastic with almost 1:1 thrust. Surprising, as it's carrying double batteries and nose lead. There is also thin wire added to wingtips to prevent the foam rubbing away when the wing tip drags on pavement. It does easily tip if your nose wheel steering has too much throw and is not centered.

Re: Starmax A-10 twin 64mm EDF Great flight report and the pictures of it in the air look great! |

Starmax A-10 twin 64mm EDF Built and flew the Starmax A-10 twin EDF. Just a heads up, don't use the specified C of G of 80mm from the leading edge! 60mm flies perfect. I used two 2200mah 3S 30C batteries and 1 ounce (28g) of lead (mounted in the front wheel well) to get the right balance. If you try to fly it at the recommended place things will get very exciting once you lower the landing gear (as it moves the C/G farther aft). The plane will want to pitch up and down with very little pilot input. Very easy to over stress the wing in this condition. I had to retract the gear and belly land the first flight to maintain control. Once the lead was added, the plane behaves very nicely. The batteries are mounted one behind the other. The front fits into the intended slot, and the second just behind in the widened cavity. I soldered two battery leads to the power lead (running in parallel). The extra battery gives flight times over 6 minutes. The power wire was extra long to begin with and did not have a deans connector. You will want a good soldering iron as the thick wire needs a lot of heat. The landing gear needs some attention as well. Install the retract linkages on the middle hole of the servo arm (for extra leverage) and adjust the endpoints to get proper down/up lock. Chances are, one servo will have a slightly different center and you will have to bend the linkage to make it slightly shorter. The metal pins in the landing gear units like to slide out of place, but gluing thin plastic sheet on both sides prevents this. Reduce rudder throw to absolute minimum as the nose wheel steering is very sensitive. If you turn with any speed, the plane likes to tip onto the wingtips (sanding them down quickly). I added thin music wire under the wing tips to act as a skid plate. I tried using throttle rudder mixing but it's not worth the programming hassle (not effective enough). Rudders could be cut out and controlled with one servo, but more nose weight would be needed. The wing root is weak and could use some fiberglass cloth. Adding spars is also an option (but more work). If you apply too many G's the wing flexes easily. Other threads have described wing failure. The best part is the performance. Lots of power. The downside is that speed builds up quickly and over stressing the wing is possible. Cheers PS The decals will be added later, I wanted to see how it flew first. |
