Any idea how could i control the throttle of this type of engine?
I has some Cox engines. .

Can not control the trottle, fixed full trottle only. The Cox Queen Bee has carburator with trottle and without fueltank.
The Cox engines need 20% castor oil only and not other oil and Nitro between 15%-25% in fuel.
