Quote: "RCM Product Test: GLH II from Ace RC.
Ace R/C Inc, noted as one of the pioneers in 1/2A, has kitted George Kurrick's 1/2A racer whose formal name of 'Goes Like Heck' has been shortened to GLH. Ace is offering the model in two versions, one with a foam wing and the other using a built up structure. The foam wing version is priced at $16.95 while the built up version costs $18.95. Both versions have a 32-1/4 inch wing span with an area of 205 square inches. In order to attain maximum performance, the standard Ace foam supplied in that version is modified with a sanding block to provide a thinner airfoil. We tested the foam wing version and had no problems with any part of the construction.
The fuselage sides are die-cut from 3/32 stiffeners on the rear top and bottom, covered with 1/4 in foam. The top front is of 1/8 precut Pop Ply, covered with 1/8 foam, while the bottom consists of 2 removable 1/8 Pop Ply hatches covered with 1/4 in foam. These hatches give full access to both radio and fuel tank. In order to protect the bottom of the fuselage bottom from abrasion when landing, a two piece, faired in, tandem landing gear is provided with the fore and aft sections epoxied to their respective hatches. A 1/16 music wire plywood supported tail skid keeps the 3/32 sheet tail surfaces off the ground.
The wing has a constant chord, swept back at 15 degrees and recontoured for speed. A triangular spruce leading edge not only adds strength but also protects the wing leading edge from dings. The foam cores have an accurately cut groove for the 1/8 spruce spar. A shaped trailing edge of 1/4 x 3/4- balsa is provided to finish the rear of the center section and to make the ailerons. The wing tips are of plywood and extend over the aileron ends. In addition, the tips are used as a pattern when recontouring the airfoil, prior to joining the wing panels. The kit includes an Ace 1 inch spinner, and Ace motor mount, the elevator horn, aileron linkage and appropriate screws and bolts.
The wing is permanently mounted, with the foam fuselage covering faired into the leading and trailing edges. The engine is mounted in an upright position and is fully accessible inside the lower half of the nose section which is faired into the fuselage.
Our test model was covered with Solarfilm and trimmed with DJ's tape. Since we were not planning on racing it right away and since our stock of TD .049's was in use elsewhere, we powered it with an .049 Medallion, fueled by a 2 ounce tank.
For control we used an Ace Digital Commander 1-8 with their new micro-servo equipped flite pack and a 225 ma battery pack. With this set-up the model weighed in at 22 ounces. Even though this was 2 ounces heavier than called for and even though our Medallion was not as powerful as a TD, she flew like a dream with very little trim adjustment required. It was fast and groovy with a flat glide and no marked bad flight characteristics. With a TD in the nose, we have no doubt that this airplane would be fully competitive. With the recommended control throws we found it quite responsive without being overly touchy.
The materials provided are of good quality and the die cutting required only a minimum of help. The kit builds fast and easy and, at the going price of $16.95 is an exceptional buy. Although we don't recommend this airplane for the rank beginner, the average Sunday flier should have no trouble with it. Just remember, it's small and fast, so stay on your toes and don't get too far out."

User commentsHi Steve and Mary, here are two pics of my newly restorated ACE R/C GLH II [main pic, 003]. The power supply is a GoldenBee dummy with brushless motor in front. Best regards,

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
