About this Plan

Handley Page Herald. Semi-scale twin rubber model.

Quote: "Full Size Plans! Ray Malmstrom's semis-scale, rubber powered, free flight twin model: Herald.

Looking for a model that will give you a new flying thrill? Something that will attract lots of attention on your local flying ground? This simple-to-build, smart little twin-motor semi-scale Handley Page Herald is your model. The plans give you all the informa-tion, but these additional notes may be of help.

Build two identical fuselage sides and join by the centre four spacers first. Hold in position with pins. Check for squareness. When dry add the remaining spacers. Take care to pin down to the building board, the wing panels, tailplane and fin after water spraying and doping. Please avoid warps!

Sandpaper downthrust formers F1A accurately. The correct downthrust angles to the propeller driving shafts is important. When assembling motor tubes to wings check
that they are parallel to each other, and the propellers have the same amount of downthrust.

Flying Notes. Balance the model very carefully, adding a little noseweight as necessary. Test glide over long grass on a calm day. When winding-up have a friend to assist you wind the starboard motor first. The propeller is prevented from turning by a small dowel-rod brake. Hold the model as shown in the sketch while your friend removes the brake rod.

Launch smoothly with fuselage approximately parallel to the ground. Have the same number of turns on each motor. Sharp banking is cured by gently warping the fin. It can also be cured by 20-30 extra turns on the motor on the banking side, but do this with caution."

    ScaleType: This (oz865) 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/Handley_Page_Dart_Herald
    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.

Hi there, Wondered if you'd like a couple of photos [main pic, 005,006] of my recently completed Ray Malstrom Herald for Outerzone? Also a few notes?
I revisited my childhood and had another go at this one to see if I could get it to fly this time! I used light wood and cut some lightening holes to keep the weight down. Also replaced the Keil Kraft plastic props shown on the plan with IGRA 6" items cut down to 5", well scraped to save weight. Covering was Dilly Japanese tissue and finish is airbrushed enamel. Markings are cut from painted decal sheet, copying the markings exactly from the plan. Weight 53 grams without rubber. Not flown yet - will report back later on results.
Best wishes,

I'd like to offer you my wishes for Happy Landings, but it appears you require a more effective wish for Happy Takeoffs first :-)

Hello,
Re HPH looks superb ! Been on my build list too for at least forty years! Looks like Mr malomstrom had ran out of down thrust by the time he designed this one ??!

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.
