User comments

I noticed you did not have a picture of the John Bell H-1 racer. I have built two from the John Bell plans [model photo & more pics 003-006]. One at the original 20" wingspan as a rubber powered model, and one enlarged 150% to 30" wingspan as a 4 channel electric radio control model. These are very good plans - I had to do my own patterns for the canopy glass and for the wing fillets, everything else is shown. I deviated from the plans on the engine cowling. The 20" shows four blocks to make cowl. I used eight on the 20" and sixteen on the 30". The 30" has extra stringers in the wing to make it more rigid. Both models use the enlarged horizontal tail shown on the plans. The formers are also still 1/16" on the 30", though the stringers are 1/16" on the 20" and 3/32 on the 30". Both models are great flyers. The wing fillets are the only difficult part to get correct, they are a double compound curve. They were easier to do from 1/32 balsa than from paper or card, and easier on the larger model due to the size. I would be happy to answer other questions people might have about building this model.

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.
