    I used a fuel refilling hose. It's reinforced and very strong. I cut it in 1" pieces, drilled two holes in them and bolted one side to the firewall and one side to the mufflers clamp.

    Hi Jim.
    Yes but MkIV HH have a gross of 1150lbs-1200lbs and I was hoping that was because of the 7/8" struts and more ribs, different tail feathers, gear and fuselage?
    I counted the ribs on mine and there is only 9 ribs, so it seems like it's a standard STOL wing with HH spars?! I am hoping this would result in a MTOW of 1050 instead of 911 or 1150lbs. Bit of course this is only guessing and until I really know, I stick with 911lbs.

    Yes I have but I haven't had it in the air yet. I am installing the battery in the tail also.

    HI Doug.
    My C-mod STOL has 0.083" spars and 3/4" struts.SN 466. it was built in 1992. Does that mean my MTOW is 1050lbs? Do you know of any documents that can verify this? In my Swedish papers it say MTOW is 911 but I believe that they didn't know that there also was a C HH version.

    I did some  ground running today after replacing the pistons on my new to me RR670. I did this procedure: 2,5min at 2500rpm, then 5min at 4000rpm and then 6min at 5000rpm and about 10 seconds at full power. I got a little high max static rpm (6700rpm) so I will add a little pitch to get it down to 6300rpm. I also discovered that at 4500rpm the rpm was very unstable, is that because of the Rave or maybe because of the low prop loading you think?
     Below 2500rpm it is shaking quite more than the 582, is that something I will have to live with? I know I shouldn't let it go below 4000rpm during flight but sometimes I just have to go idle and wing slip to get down because the Avid Flyer is so light with high lift wing.

    I just started my new Rotax Rick 670 with C-box 3:1 and 3-blade 72" Power fin. I've been running it for 1 hour now and I also think it shakes quite a lot at startup and at idle. I guess I just have to stay above 2500rpm. I will try to turn out the air idle needle.
    I would love to have a clutch bit the weight penalty is not ok on my Avid Flyer mod C.

    Fixed some clearance in the firewall and managed to hang the muffler.

    Soon, I will join the King Kong family :-) 
    I am installing my 670 right now. Need to modify the firewall a little. The mod C engine cowling is getting butched around the E-box... One day I will do some fiberglass work to fix this.
    The biggest concern now is to find a way to hang the muffler in a good way.

    It's crazy how there are so many different requirements from different countries to get to the same results! Sweden where I live  is one of these and often the Swedish authority just accept the modifications developed by other "respected" European countries. The UK did the same job but those mods are not as near as extensive as the Switzerland's mods. Still the UK mods are "UK certified" for the same gross weight. So if I as a Swede would want to get higher gross weight approved I would choose the UK mods to copy. 
    There are as many different "load calculations" as there are aeronautical engineers !

    Thanks Nlappos. 
    Unfortunately I am located in Sweden, so I need to fix that exhaust by myself. I have looked at it and it seems doable.

    I am about to buy an RR 670 that has a Kitfox exhaust. I want to install it on my Avid Flyer C but wonder if the exhaust will fit? Anyone have any thoughts about this?

    Just wondering, how  did you rebuild your struts? I am thinking about doing the same with a pair of mine.

    Hi Japowell.
    How is the wing mod going? I am also about to extend my aerobat wing. I got some documents from the British LAA / PFA. Do you have any drawings or instructions for this?
