About this Plan

Harold Krier's Great Lakes Special. Radio control sport scale model biplane. Subject is the highly-modified 1931 Great Lakes Special flown by Harold Krier in the 1950's.

Quote: "Over the past 10 months I've been having a ball putting the ship through its paces. In fact, I haven't had a proper aerobatic biplane for the past 10 years, and 1 swear that I feel 10 years younger again. Complete flying enjoyment is guaranteed with this machine, so let's get down to the serious part now.

My prototype model uses an Enya .46 4-stroke turning a Graupner 11 x 6 grey propeller and burning 10% nitro 2-stroke juice - I like plenty of lubrication in my engines. The exhaust pipe sports an O.S. pressure fitting which applies exhaust pressure to the 6oz fuel tank. For first flights, I suggest that you add lead to get the CG at the forward point. When you have become used to the model, try moving the CG back to the aft position. The main wheels are set quite well forward and the gear has a wide track, making the ground stability good. However, the rigid legs make the model quite bouncy over rough ground. For all take-offs, use the low control throws as shown on the plan. A spot of up elevator at the start of the run will prevent nosing over, and slight right rudder is used to keep her straight. Using full throttle, the model breaks ground in less than 10 yards, and pointing the nose upwards produces one heck of a climb out. These small 4-strokes have come a long way in the past three or four years..."

Steve & Mary - Here's Gordon Whitehead's Great Lakes Special from October, 1989 RCM. It's 47 inch span, for a .40 2-stroke or .46 4-stroke. I rescaled and massaged scans provided by RCGroup's tri-pacer in post http://www.rcgroups.com/forums/showpost.php?p=33198440&postcount=5432 and attach both combined and separated plan & parts scans. I also attach the article scan done by RCG's davidterrell80 in post http://www.rcgroups.com/forums/showpost.php?p=33196998&postcount=5430 Wear 'em in good health!

    ScaleType: This (oz7223) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Great_Lakes_Sport_Trainer
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
    Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

Notes

* 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.

Scaling

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.
