This project has added RC, Ducted fan, Glider and model into its working list. The latest model is F-14 Tomcat scale 1/50. Its lenght is around 1 feet ++

Dear Airdave,

The scale now become 30 inch, foe a Gripen. I don't know exactly what size it is!

Dear Jim,

Due to my team is working on ducted fan and kite and glider and model projects so the size is not the matter. We are challenging for experiment of the paper model to become a radio control, which using the paper as material. This is quite challenging for us!! I hope that next week we can upload photos and video for your viewing!!

Hello Chaiwat

RC paper model ! it's so cool. I'd imagined how possible to build. Your project should carry out much idea for the RC+Paper model lovers. Wait to see photos and video.

WE found that the model for RC ducted fan Gripen need at least 90 cm. fro get the ducted fan in, OMG.

So "cheat", with a bit of radical thinking.
Use a fan that normally cools a computer chip (or even use two in tandem, one set behind the other: as long as they both rotate the same way airflow stilling in the duct won't be an issue), just run it at a far higher speed than normal.
Build ducting to suit and fit it to the fan.
Yes, you'll burn the fan out, after maybe 5 flights, but it should be cheap enough to replace, and a lot less expensive than paying for a "proper" RC model ducted fan.

And because a computer cooling fan is a lot smaller than an RC ducted fan, you might be able to reduce the size of the model from 90cm.

Just a couple of humbly offered suggestions Chiawatkom my friend.

Kind and Respectful Regards, Uyraell.

Extremely good idea, we are on experiment process.

I'll be very interested to know how your experiment turns out Chiawatkom my friend.

I'm glad the suggestion was of help.

Kind and Respectful Regards my friend, Uyraell.
