IMAC Delro 2.5M Raven Build

[Wacobipe]

Final test fit of the firewall...I taped the firewall in place and the assembled/disassembled the engine/spacer/header/etc... to make sure I can get it all in and out once the firewall is Hysol'd in place...there is not much extra space but it all fits and I can get everything in/out without too much headache...and it is super clean so I am happy! I still want to drill the holes for ignition wire, fuel supply, and throttle and choke servos prior tpo gluing in place. so hopefully I can get that done tomorrow

And a quick shot for @Jlc to show how little I had to cut out of the bottom hatch for the DA-85...looks great and should be able to get some excellent airflow over that big jug!

just came across this thread, and i want to congratulate you on a beautiful thread!!! i am enjoying seeing all you have done so far, and i am joining in with the other guys. You have some great ideas!! i like the hinge for the canopy/hatch area. very very cool!!! My only concern is your three blade prop. Looks like your 85 may over-rev with this, so you can probably only go to half throttle.

I might upgrade before the maiden flight...

I think the balance issue will be worse than the over-rev issues

Lol... I hope you know I was kidding about the prop!!!
Love that airplane. Looking forward to seeing you put it all together!!

Ignition mounted...4 thin slots in the firewall keep the Velcro straps in place and keep it clean and simple!

The Firewall is Hysol'd in place...

There ain't no turnin' back now!



There's enough Hysol to get solid coverage between the firewall and the fuselage (I am amazed hoe perfectly the firewall fits the entire fuselage wall curvature). Once this dries well I'll remove the engine and then build a nice thin bead all around both sides of the firewall to make sure there are no gaps at all...then I plan to lay a fiberglass tape around both sides of the firewall, 1/2 on the firewall. 1/2 on the fuselage, and I can't think that baby is ever coming out of there, at least with the plane in one piece

Hey Wacobipe,I really like the work you're accomplishing on your Raven. I bet it's going to be awesome when it's finished.......

BTW, I'm glad you changed your profile picture back.. The puppy dog was cute enough, but I like your M12 so much more.........
My flying buddy is finishing up his right now. All he has to do is attach the canopy, final sand, then cover the beast. I wish I had time to build one.
