Getting a Duece and Bertha together

[stevecarr]

Here what happen when A Wild Deuce and Bertha got together.
Problem is I think it needs nose weight .
Anyone bash a Bertha with a Deuce?
I've got one under construction also.

Here's another angle

 

[jflis]

yea, I'd add some nose weight to *that* puppy ...

looks cool though

 

[powderburner]

This looks like something that should be added to astronboy's new product line

Maybe call it the GooGooney?






Oops, where are my manners!
Steve, welcome to TRF, we're glad you joined us!

Creative bash And very cool color scheme.

I agree with Jim--it'll definitely need some noseweight... But at least you won't have to worry about the motor exhaust scorching the edges of the fins

 

[astronboy]

I did a quick and dirty roc-sim of a twin engined Baby Bertha. It looks like you will need 20 grams of noseweight to get this sucker stable.

Attached is my RockSim version 5 file. For one caliber of stability by the Barrowman equations you want at least 15 grams of additional weight in the nose cone for a flight on two C6-5 motors.

One final picture .
Both are now flyers and part of the fleet.

 

[jflis]

AAAAA! It seems *unholy* for some reason...

 

[stevecarr]

Sorry next time I'll put my Deuce in the picture.
For my next venture a Deuce with one of these.

Side view

 

[jflis]

Looks like a *stutter* to me... Deu-Deuce...
kewl

Someone had something just like that at NARAM. First flight was on only 2 motors, but perfectly straight.

Second flight was perfect all around!

 

[Elapid]

must be a Force!

i liked this idea so much, i made a Deuce-style MMT for my Super Big Bertha with 2 - 24mm motors!

Cool! that matt green & dull yellow paint scheme just looks awesome! Well done!
