One other way to get a good needle valve setting is to switch to a Fora F2D needle valve.  It requires some simple mods to the case and a change in venturi size.  The NVA body is 4mm, and the case has to be reamed out to fit and counter bored a bit(can be done by hand if need be) for length.  The result will give a needle setting with about 1 full turn between 4 cycling and 2 cycling.  Seal the needle with a short piece of silicon fuel line.

So -- Really Slow Combat?  Your next stunt ride will be a JU-52 with slime power?  You're giving up on flapped stunters and building a Skyray?

Howard was axing for Steve Holt, who may not be a SH member. I read on here that Tower is out of the .20FP NV Assy. And I'm wondering if Fred's stock is front or remote type? I have a .10FP RNV assy and another that I think is a .35/.40FP RNV, and they're available.  y1 Steve

Hell a few years back I bid on a 25 engine lot...mostly junk.... won for $38 + 10 bucks shipping....
Heads, NVAs, Back plates, about 50% I stripped for my parts drawer and pitched the horribly gunked up and seized engine.... not wort my trouble to crock pot and refurbish........really Virginia  $1.92 per engine

In the lot I got 11 well preserved and working engines... Cox .049s, OS 30 stunts, Enya 4224s,  and three fox . 35s
