Nobler ARF

I recently bought a Nobler ARF and when I attach the wing to the fuselage I have a gap at the front can anyone suggest a cure as I want a good tight fitting wing I considered grinding part of the front former away to accept the angle of the wing where it tapers back but dont care to flatten the leading edge as that seems to me would weaken the leading edge, my only other choice seems to be to strip the covering of and build up the gaps with scrap balsa but really dont care to end up replacing the covering completely after all it is a ready covered ARF that just needs minor changes to bearer strength and control system. Also has anyone any suggestions as I have an L&J Fox 35 and a Brodak 40 but unfortunately the Brodak wont drop into the hole mounts for the Fox the bearer spacing is the same but I really dont like to drill more holes in the bearers and especially dont like to drill additional holes in engine mounting lugs.should I decide I need more power.

With that LJ Fox.. you won't need anymore power!

On my Nobler, I used epoxy to fill any gaps, then used matching blue Luster Coat paint ( sapphire blue ) applied to the joints with a small brush. After touching up all the joints, the plane really looks good.

Is the wing be held off by the wing dowel pin? I had to conture sand my Arf wing pin to get a real good wing seal at the fuse.

I'd go with the Fox. I put time on my Brodak (late engine with large muffler opening) in an ARF Nobler and it was too strong. Set at the break and with an APC 10 x4, lap times were 4.5 or less on 5% fuel, 63" lines. Should have tied a streamer to the tailwheel!

The Fox should be great in one unless you're in a real hot climate where power is reduced by the thinner air.

Added Edit: By the way, I have another ARF Nobler my self and it is getting a Merco .35 Redhead. Merco later made a Black head series which had big problems but the Redheads were good engines, just a bit stronger than the Foxes powerwise.

Like others have said, go with the Fox. Mine has a B40 in it and it is overpowered. It likes to wind up in loops.
by the way, be sure to make darn sure the incidence of the horizontal stabilizer is zero to the wing. Mine was off and it kept wanting to climb and the outside loops were huge and the inside loops way to tight. It took me two trys to get it almost right, but it is still off enough to make the loops large/small. Tried all the other tricks, but incidence meters don't lie.

On my NARF I had to relieve the wing-holding dowel, on the bottom side, almost 50% and then reprofile the wing cut-out with a sanding block in order to get a clean fit.

That gave me a good wing-fit WO having to go the filler/paint route. I did have to shim the 'fuselage fill' piece but thats on the bottom.

Throw in an old, 1/2 worn out Fox, and you should be happy.

(IMHO Fox-35s run best when theyre "about worn out". LOL!!!)
