Old "new" Webra Bully converted to gas.

Silencer: DA 50 canister on a 22cm long header.
Ignition: RCexl with an unregulated A123 pack.
Fuel: 2% unleaded.
Temp: 10-15°C.
Propeller: APC 18x10 "sport"

Maximum 7800, with a steady idle of 15-1600rpm, after warm-up.

I´m considering trying an APC 16x12 or 14 since the engine is going into an enlarged Hots, and I don´t have much clearence when running 18in props.

Very intersting! Do you have a photo and is that a profile plane you are putting it on?

thanks,

Hi Ernie...

The Hots hasn´t been built yet, as the "kit" is being lasercut by a friend. I hope to have the parts soon though.
It´s a 160% enlargement of the original "The Hots", but modified to have a removable wing, clipped at 180cm (70,9in), and a cowl which makes it quite a bit more sporty. So for now I only have a screen shot of the plans and a 3D rendering of the finished model to show you.

Specs are:
Span: 180cm (70,9in)
Length: 142cm (55,9in)
Wing area: 70,6dm² (1094in²)
Weight (est): 6kg (13,2lb)
