R/C Combat Gremlin kits:

The R/C Combat Gremlin was developed in New England by Eric Henderson and has been flown by several local clubs since early 1991 and spread across the country to start the streamer combat revolution. It was flown as a demo event at the 1992 NATS in Chicopee MA. It was featured in the February 1994 R/C Report as a kit review as well as the original December 1992 R/C Modeler magazine construction article. We have been supplying foam cores and kits under agreement with Mr. Henderson since the original 1992 construction article. We have expanded the Gremlin family recently with two electric offerings, the 30" Speed 400 sized Mini R/C Combat Gremlin as well as our newest plane, the full 48" sized R/C Combat GremTwin. Both of these new versions share the great handling and stability of the original design. We market multiple levels of kits and replacement parts. Each plane is available as a full kit with all the wood parts precut (lasercutting for the Twin and Mini) as well as an Almost Ready-to-Cover version which does the majority of the building for you with a prebuilt wing and fuselage(s). For our original Gremlin we also offer a short kit which includes cores and PVC Fuselage but just patterns for the wood pieces.

We now offer Vinyl Gremlin Graphics through our PayPal order form.

The Gremlin is used in single design R/C streamer combat contests around the country but is a fun, durable plane to fly and has become a standard "hot dogging" plane at many New England flying fields. If you can handle an aileron trainer, you can fly the Gremlin. Fun, low cost, durability, and short (about 6-10 hours) building time make this plane a winner. For .25 to .40 size engines. We do have dealer pricing for quantity orders placed on Hobby Shop letterhead. Distributor inquiries welcome.

NERCCA Combat Newsletter:

We currently produce a newsletter for the New England R/C Combat Association (NERCCA) which come out about one a month during the contest season. It is available for free by email by sending a subscription request to rc-combat-lovers-request@world.std.com with the message "subscribe" in the body. Past issues and contest reports with pictures are available in the online archive as well as a Gremlin combat contest calendar.

2 Meter glider wing upgrades:

We offer full replacement wing kits for upgrading either the Gentle Lady or Spirit to a more competitive intermediate level glider. These popular gliders are great to learn on and we offer a low cost upgrade to keep them flying so you can develop your intermediate skill levels. The wing planform is a 24" inboard panel with a 9" constant chord and a 15" tip panel tapering to a 7" tip. These wing kits include 3/8"x1/8"x18" basswood spars with vertical grain balsa shear webs, balsa leading edges, full 1/16" balsa sheeting, fiberglass tape for the center section and trailing edge, and instructions for creating a bolt on polyhedral, aileron, flap or full house wing. S3021 or SD7037 airfoils available from stock or your choice of airfoil in the same planform for the same price with a possible slight delay. $35.

We get a lot of questions on airfoil selection. My feeling is that you can't go wrong with the SD7037. It penetrates well and has a good speed range. I personally have flown the S3021 with polyhedral and flaps and the SD7037 in a tiplet planform with flaps and ailerons and prefer the SD7037.

Quickee 500 cores:

We offer low cost, quality 25" panel Quickee 500 cores for $8 per set. We're using the Dodger airfoil that is popular in NEPRO competition. The cores are cut to use 3/32" top sheeting and 1/16" bottom sheeting.
