My GeeBee Z Dumas kit#403

[John galt]

I'm so glad to have found this forum...I imagined there were other people that enjoyed building as I did, just never actually met one.


Cheers!


this was my first attempt at anything close to semi-scale...

i skinned it in 1/32" balsa and painted it with enamel in our company colors

i used a DC motor so the prop would spin but would have some resistance, it looks like it could be a piston engine spinning down after a good flick of a finger

i used foam rubber RC airplane wheels in place of the plastic ones

and as can be seen in the pictures i carved the wheel pants out of 1/2" balsa

Looks nice with the sheeting for scale appearance. I built a Herr GeeBee R2 and went to the same effort of adding stringers and sheeting for a scale appearance. Dumas has an R2 kit also, that would require the same efforts for scale looks.

For the most part...I should have resized my images befor uploading...seems they've been truncated


I may try again this weekend..

Guillow's bought Dumas? When?

Guillow's bought Dumas? When?

This IS a general model airplane discussion forum. Most of us here are Guillow builders, that's all.

Nice clean build....how did you manage masking the scallops on the wings & fuselage?

[John galt]

I applied masking tape to waxed paper, traced the pattern onto the masking tape and cut it out with a razor knife.

If you do this be sure there's very little tension in the tape as it goes on, and use tape wide enough for the whole pattern otherwise there will be seepage at the seams.

There will be more pictures of this process when I post pics of my P51...


Moment pleace...

I've been using a similar process since the 1950s except that I use a piece of window glass to lay out the tape on and if the tape is too narrow overlap the seams. Using window glass you can push down the seams harder. This also works for the masking to paint on canopy frames, especially on the old Comet kits where they gave you such a nice pattern.

Since I use an airbrush now I have been using transparent friskit, and for some models, Guillow's white tissue, sprayed with a few coats of Krylon and applied with 3M Repositionable glue stick (Post-it note glue) instead of masking tape.

By the way, that fuselage is one of the most remarkable sheeting jobs I have ever seen.

I have a few of there RACER kits. I like the way you covered with sheet balsa. I will do that on my newest creation for least the Engine Ring! I plan to fly mine FF with rubber motors! Mitch

Thank you for your build... Although most of my models are still Guillow's. Guillow's does NOT make these wonderful racers... I took your idea for the cowl on my Red Lion Racer:

I hope to have her ready for my Denver trip... Now back to Guillow's... Mitch

Glad to meet anyone with a great attitude like yours. Even more so since you're a builder.

Guillow's bought Dumas? When?

I enjoyed seeing Mr. Galts' Gee Bee. Get to the point. If someone doesn't like seeing anything other than Guillows, then say so, rather than a round-about comment. Keep in mind Bill that your enlarged Guillows builds are not exactly Guillows kit builds. I'm not aware of anyone making any critical replies about your contributions.

I've almost bought that kit so many times. Such a pretty plane and one of the next on the list. Nice cowls on these radial engined racers certainly does do them justice. Spent a while on the Herr GeeBee R2 cowl, and it was worth the effort.

[Mitch]

FAC rules only require picture of Radial Engine... So I plan to make a photocopy of my Guillows Orberussal:

PS The Tires on these models do not say GOODYEAR... They say GUILLOWS!

Check this out...

This is what Dumas gives you for the front end:


ADD what you can get from Guillows:


Put them together and:


Cut off the "engine?" from Dumas to leave the cowling:


So for a couple of dollars in parts from Guillows, you can enhance the FRONT END of you Speed Racer!

You can customize you engine to look like what ever engine you desire! So my Gilmore Racer is now sporting a Orberusal... I will need to update that to a Pratt & Whitney some day! Mitch :

Beautiful job ! I see you skinned it with balsa. Is that an option? Did you airbrush it?
