Hustler XD-7 Delta (oz2873)
About this Plan
Robert Baldwin and Weldon Smith's, Hustler XD-7 Delta from the 03-62 issue of Model Airplane News.
Later kitted by Midwest.
Quote: "Evolution of a three-cornered airplane - it was impossible to believe an RC model could perform so well but after the authors described extensive design program we felt it just had to be told.
The symptoms of this unusual form of madness were first brought to light shortly after the Pylon Racing Event was introduced to RC. Our bunch, in one of our regular, every Monday night, get togethers was busy discussing the possibilities. It sounded like it would be a lot of fun. Naturally, our conversation got around to what kind of model would be best for it. Whatever it was, it should be an exceptionally clean design. That's where the delta's got into it - you ought to be able to build a delta about as clean as anything - no fuselage, no separate tail feathers; just wing, engine and wheels....

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

Hi Gregory. Suggest you start with the FAQ page at https://outerzone.co.uk/faq.asp#downloadplans which explains in detail how to download the plan.

Just finished this marvel! Waiting to maiden so will see. I have made a few changes to bring it into the 21 century:
1. Converted to electric. 350W motor and 3s. 4s also possible.
2. Adapted the nose to fit electric and made the wing even more aerodynamically clean.
3. Made the fins removable. I think these are the weak point. So something replaceable is good.
4. Removed the undercarriage. Saved weight. Put a skid as recommended by a German modeller who has made several.
5. Modern coverings has allowed me to remove the bottom i intermediate cap strips. saving weight.
6. Importantly have only two elevons, mixing, rather than separate elevator and ailerons. Reduce weight and complexity.

Hi, Just finished the old interesting Hustler DX-7. Would like to add the AUW with two 3s 2200mW batteries is 1.5kg. Just added some pictures of the build [005-011]. Might help some future modeller as the plans are not real clear nor adapted to modern equipment. 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.
