Very impressive! And amazing to see such a "small" model actually fly!

Wow, that's amazing! I would guess a volume of 75 ltr. That would mean it's not heavier than 75grams. quite sportive... Anybody know this chap?

[Alan Sherwood]

I am flattered by the interest shown by 'static' scale modelers. Yes it is fully buoyant (on helium), has a rigid frame and a single internal gas cell, and is radio controlled. Volume is 90 ltrs. Using the plans I posted here, I can say this model is accurate to scale (1/120th) to the millimetre. The one deviation is the aft propeller, which is well oversize, a concession to flight performance (it does about 4 knots). I built this about 10 years ago, with the technology of the day that is the best I could do. I am currently (among other projects) working on a model LZ-120 (Bodensee) which I hope to get down to 25 ltrs.
Another non-scale model of mine is described here http://www.rcgroups.com/forums/showthread.php?t=462909
In fact the blimp forum of RCGroups would be recommended reading for all flying model airship builders.

That's a great link! Glad to see some interest and discussion on flying airship models. I'll be sure to post a thread pointing over that way. . .

:D

BTW, did you see the HUGE flying model of the R-101 over in Great Britain?

[Alan Sherwood]

No, I didn't see the R-101 model, although I do know Nigel Wells and I have seen his previous R-100 model.

BTW, I might say now what a great site this is, I have found sources for data and drawings I never knew existed. Just as good for flying scale as static scale models. Well done.

BTW2, I notice I am identified as a 'junior member'. What does that mean? I can't imagine the DOB I gave in my profile could possibly put me in any 'junior' category

[Charles Adams]

Ha! :LOL: "Junior Member" status is based on the number of posts you've made to date. . .

Glad you're enjoying the site! It is about time we airship modelers had a place to gather online. . .


:cheers:

Hello Alan,
this is a structure inside your R101 model, is it? Did you use crp?
Best, Johannes

[Alan Sherwood]

Yes, there is structure inside, all balsa wood no crp.

Alan, have you been able to do any more work on a small rigid airship?
your r-100 is amazing especially considering when you built it. i want to try one but im afraid of the frame and covering aspect of it. i think that jap tissue would work but i have yet to get any.
I must say though, that the pictures of your R-100 is what got me interested in building one.

I am currently experimenting on a method of building smaller rigids. Watch this space.
