Why not mount the motor directly to the firewall without the metal mount?
Not sure what you're referring to as a metal mount? The Q60 comes with arearmount that is attached directly to F1.

Maybe someone else can chime in here. I am not familiar with the AXI F3a motor.

Yes the AXI mount will work, just fine. My electri Pentathlon, had the AXI 5330 f3a motor, had more power than needed

Yes... but the fire wall it too far back. i have not used standoffs to mount a motor.... I built a new firewall and put it in at the correct distance.

If I may suggest, take a look at the "Viper build" thread on this forum... Jeff has photos showing how he built his rudder, which at first glance, seems similar in construction...

the one on the left looks like the rudder out of the kit. what part is not straight? the leading edge where you have the ruler?

MT,

Sorry you are having some much trouble.

The rudder design is not typical as the thickness tapers from the top and bottom and peaks at the 4th rib from bottom (largest chord). If you attempt to build and/or sheet with the structure laying flat on the table, it will result in a bowed shape. The frame can be dry fitted in the jig. By fitting sheeting between the frame structure and the jig, it can be ca'd together while in the jig under slight pressure (sandbag, etc.). Without removing from the jig, the second side of sheeting can be applied. Afterwards, the TE sheeting can be gently sanded back to the rib TE's and capped with scrap balsa.

Hope this helps a bit.

Best Regards,
Mark

I glassed my Pentathlon and it came out light. I used 3/4oz cloth and Zpoxy finishing resin. I also watched Don Ramsey's cd on doing a light finish and also used the microballoons brushed on before the epoxy it setup. First time I've tried this method over using polyester resin and not sure I like it as it seemed the epoxy took a longtime to fully cure hard. As I later found out the trick may be to use Acetone as the thinner vrs alcohol. Also I covered all the tail surfaces with med silkspan and nitrate dope to keep the tail light. K36 primer brushed on and ALL sanded back off, then Concept paint from Radio South. Good luck, you will love the way the plane flies.

Use this link http://pages.suddenlink.net/donramsey/ and click on the how to video link for ordering info. He also covers the microballoons technique in the video. Good luck with your project.

mtcarey . You can find all the info in the video on the Black Magic thread . I have put a link below, it will get you right in the middle of the surface prep and glassing . I am about to give it a try on my Pentathlon also.

Hmm.. Maybe a Pentathlon Evo fuse with Dave Snow's Spark wings and stabs? That could be an interesting combo...

I will have it in Houston. Dont want to risk the Beryll if the wind picks up too much so I can still fly with a good plane.
