A few commercially available parts are carried for the primarily for convenience of my rework customers. If the parts are ordered at the same time as an engine rework or if $30 or more parts are ordered at a time there will be no shipping charge.
Glow Plugs - Three Merlin glow plugs are carried which are applicable for free flight and the modifications I perform.
-
1) The 1125 Green plug is a direct replacement for the vertical coil heavy duty Nelson plug. A primary difference is the use of a 5/16 hex drive in place of the 3/8 hex used on the Nelson. It will not fit the Cox 020 modified for the flat coil Nelson. Cost per plug is $5.45.

2)The 2019A is a package of 3 - 2019 drop-in 1/2A vertical plugs that fit the standard Cox 1/2A setup. It is also a fast runner and comes with a clamp ring included in the pack of 3 for $14.95.
Little Red Caps - If you are having a difficult time finding the “Little Red Caps” you can get them here for $3.00 for 12 or $5.50 for 24. They come all rolled up like the Red Cap in the lower left corner of the picture. They can be assembled into small single lobe units or large double lobe units depending on your fuel consumption.
K&B NVA - The three piece Needle Valve Assembly is available for $20.00. It requires drilling out the spray bar hole with a #21 drill and tapping the hole with a 10-32 tap. This NVA is an excellent replacement for the stock through the venturi assembly for a pressure system.
