HOLY SMOKES! Do you have a hold of IT, or does it have a hold of YOU?

Good flying (and fishing),

Wow , -What a monster. Life is good.

Love to hear how your Ultimate fly’s. Hope to fly mine this weekend since I just finished it.

Good Luck!

Well, now that I'm finishing up, I see thare is no real reason not to remove the covering under the firewall since that entire area is covered once the cowl is installed. Sometimes I'm so dumb I scare myself

I mounted my YS91 inverted. Anyone have any tips on the best place to install a fuel filler and a remote glow plug connector?

Glad to hear you finishing up your plane.
As you know, there isn’t much room for switch and charge jack let alone a fuel filler and a remote glow plug connector? I decided to install my switch charge combo sideways (vertical) behind the former in front of the servos. I installed the fuel filler through the lip in front of the firewall. It also goes through the cowl. As for the remote glow I opted to go onboard glow so I can’t help.

Good luck

I used a seperate switch and charge jack mounted on opposite sides of the fuse, with a home made holder for the switch, and only a 1/10 diameter hole for a wire running through the fuse to the switch. I think I can mount the remote glow connector at the bottom rear of the cowl on one side, with a round notch at the back of the cowl for it. But the fuel filler is trickier because if I mount it aft of the firewall I will have to plumb it behind the firewall and drill another hole in the firewall in another location to run the fuel tubing from the filler to the carb. Additionally, the way I have seen YS engines rigged is with a "T" in the pressure line, running to a externally accessable fuel dot so as to release pressure before refueling or when finished flying, so I will also need a place to mount this fuel dot. "Almost Ready to Fly' is a rather big "Almost" sometimes, eh?

Guys...I have aquirred one of these that has been started by someone else. The problem is that it seems to me missing the wing block (the spar that the bottom wing screws into) It looks like it was just glued into the notches. Is this a part that Goldberg Models carries, am I just gonna have to make one, or do I now have a worthless plane? Anybody have a pic of this part?

Thanks

Probably going to have to make it. Goldberg could probably get you one from the kit version of the plane, but I can't remember if they are for sure the same. You could probably make one for $1.00 worth of hardwood or even some ply. Just epoxy it in and maybe put a couple of tri-stocks for back up. It's just a slightly tapered piece of wood (look at the notches in the fuse for shape) with a hole in the center for a blind nut. With the top wing also being attached at center, there isn't nearly as much pressure or torque at that point as you would find in a monoplane. Hence only the one screw. Be sure you have the ply doubler that glues to the bottom of the wing where the screw goes through too. Good luck.

What aftermarket mufflers are available for the YS91 which would be appropriate for my inverted YS91 on my Ultimate? It fits beautifully inverted with minimal cutting of the cowl necessary, but the way the YS muffler is attached, I would have to cut out a massive section of the cowl just to install the muffler.....

I really like this plane. Dog gone it - Now I'm hooked on bipes

Tailtwister,
Thanks for yor help. I think I will try to make one out of 1 x 1/2 plywood and just sand to shape of the notch. The plate seems to be there for the bottom wing. I never have had a Bipe before, so The one hole did make me wonder. And for all those that are wondering and/or care, I'm gonna power it with a Saito 150 (Need the extra ponies for the thin air here in Co.) Just hope it flies as good as it looks.

TerraFirma,
Let me know how you like it...thats the combo I use too
