F105 Thunderchief
 

Hello group, I have been away from R/C for fifteen years. I recently started looking at what is now available online. I am amazed at the changes.

I am wanting to scale up Steve Bage's F105. The plans I have show a wing span of ten and a half inches. I would like to scale this model up to around thirty six inches in span and put a electric motor in the nose. "prop jet"

Can anyone direct me to a thread that will help me calculate what motor and prop I would need for the wing area I am planning?

I would also like to know why most prop jets are pushers and not tractor?
My guess would be CG issues.

Thanks in advance for your help.

Steve

Hi Steve :ws: check out Heads up Rc on a power system, Email Jeff and he can fit you with a Perfect power system, A Lot of People here use Jeffs power systems and Jeff is great to Work With.

WOW! That's a nice link! Thanks Chellie!

this would be my Recommendation using a 6x5.5 APC prop :ws: on 3 cells, later if you want to go Faster, use a 5x5 or 4.5 x 4.5 apc prop on 4 cells use a wattmeter to be on the safe side :)

BTW ???? Welcome to Wattflyers :D

+1 on that and Welcome!:D

How long has that been there? See all the cool stuff I missed...

looks like it's quote night!

Han Solo: A Jedi Knight? Jeez, I'm out of it for a little while, everyone gets delusions of grandeur! :Q;-)

Thank you all for the help. FYI, not looking to break the sound barrier, I just want a cool sport plane. I like scratch building and I like oldtime methods. I also build rubber free flight using tissue and nitrate dope. This is the planned method on the F105.

Cool :ws: My Father got me started with CL when i was about 12, that was so much fun i never left model aviation :ws: I am a old time builder too, i built models from balsa, tissue, ambroid glue and dope too, I like building Planes from Foam now, its quick and fun, here are some of my scratch built planes if your interested, Take care and have fun, Chellie

Hi Chellie, just looked at your planes. Umm,...... ah,....... WOW!

Steve,

Great to see some interest in my old F105 plane (I'm Steve Bage):D

An scaled up EDF conversion has already been done and it flies fantastically. Here's the video:

The builder goes by the name Boogie over on RC groups. He did a build thread: http://www.rcgroups.com/forums/showthread.php?t=1314878

You could PM him for more info or I can put you in touch if you drop me a PM here. A prop rather than EDF would simplify the conversion though I think a pusher might be the way to go with the battery up front to achieve balance.

I hope you do go ahead with the project, i'd love to see another thud take to the air.
