Does this actually fly? (Hall's Bulldog)

Is this just a model, or is it ready to stick electronics into for R/C use? My impression is that it's just a model. (the prop looks too cheesy)

I wish someone like Parkzone or Hobby Lobby would come out with a Bulldog, so we could not only add them to our fleets, but we'd have spare wings, spare wheels, etc. Kits seem so one-crash-and-it's-done to bother with. I think if I had to fly something I made myself from the toothpick level, I'd be too nervous to enjoy it.

That is a "free-flight" model. You wind up a rubber band and let her go, no RC control.

If you know what you are doing you could convert it to RC, but that is a great deal of work.

If you have the skills to build the plane itself, making it RC is no great deal of work, especially with today's tiny gear. These kits are converted all the time in quick fashion (visit the scale forum for tons of examples) just need to add in the control surfaces. The basic conversions just need the rudder and elevator as these are free flight models typically trimmed to be responsive on just these two surfaces. As kits go they go together well being laser cut, etc.

It's certainly not for beginner pilots in any way, as far as I know it suffers the same control interference over the tail plane that the full size suffered from (the extreme gull wing shape). But if you enjoy building, it's far from being a taxing project... and then you throw into the mix that balsa does fly better, and that flying your efforts is the most rewarding thing you can do in this hobby... everyone should give such a project a go!


Before the Bulldog, you could try the Gee Bee Model E from the Dumas line... it's 30" and would be a little more forgiving than the Bulldog in terms of building and probably a little less quirky in the way of flying. Certainly the Stinson would be an easier introduction to the art form.

...heck, I just picked up a Dumas GeeBee E myself the other day

Is that a Dumas conversion? Just how twitchy is it? The Realflight 3.0 simulator makes it seem very stable and easy to fly. I like how it flies there. Is it overly sensitive to stick movements, or more like it stalls easily, or what?

Thanks for the pic. Still like the looks of it, even if it doesn't fly that well.

Looks like a GeeBee, but with high wing and elliptical.

Slightly smaller than you are thinking, but at 34 inches Rob Caso's is a great flyer. I got to try it out last summer and hope to build my own once I build out my new workshop.

Hello,
I saw a photograph of this model in the spring park pilot mag in an ad for turnkeyrc.com (seems to be your website Rob). Unfortunattely, it is down and I can not have any information about the kit. Can you give me informations about the content of this kit, the price, ... ?
Thanks
