[ON SALE] World Models Ultimate 100cc 33% -Purple

Please note that due to the large size of this item, we can only send it within the U.K. (items sent to some of the more remote parts of Scotland may take longer to arrive).

World Models Code A173S1 33% Purple/White Ultimate

The now famous Ultimate 10-300 originated as Full-Scale Pilot/Designer Gordon Price's desire to improve the looks and performance of his Pitt's Special. After he had produced new wings, canopy, fuselages, and wheel pants for the Pitts, it was a natural step to produce his own airplane.

The original 10-100 flew with a 100 HP engine, and while the plane flew well, vertical performance was limited. The next version (10-200) was 6" longer, and could accommodate a larger power plant, but eventually, Gordon updated the design to the 10-300, which was 3 feet longer than the 200, and could handle a 300 HP engine.

The rest, as they say, is history.

Enya No.4 Glow Plug (med)

A great quality medium heat glow plug from Enya. If you slightly more Nitro and you find an Enya 3 is not delivering the top end R.P.M you think you should be getting then try a number 4. Often a Number 4 can increase the top end R.P.M without the tickover suffering. Try one and see.

Glow plugs are considered to be consumables - But by using a low voltage to start ( under 1.5 volts) and not burning the plug dry, you prolong the life of your glow plug. It is also worth washing out a new engine after running in to prevent small particles shorting the plug and destroying it. Blowing plugs on new engines is less common now a days, but is still something that can happen.
