Willy Monster

Hi

I have a kit of the Willy Monster that I am thinking of starting to build soon,
however have little details and can find nothing on the net about it.

I am not sure of the completed weight to decide on which engine to use for reasonable flight.
Choice is either an ASP90 4 Stroke or a soon to be delivered NGH35 4 stroke
petrol ignition (probably way overkill).

Model is 120" ws, 1980 sq" area and trainer style with clark Y airfoil.
It is the 3ch version (no aileron) which I hope to modify for flaps to allow
landing in a smaller area and reduce float on landing.

Has anybody built one of these and have experience of it. ie all up weight/engine?

I had built the smaller version which went through many diesel engines (09)
and electric motors and was finally donated to the local air league for the kids to learn on.

thanks Alex

I had one of those long ago and used a 108 ASP it was over kill and I wouldn't worry about flaps they fly pretty damn slow as it is ... with that much wing area I wouldn't worry about your weight to much as long as its not tail heavy it will be fine and just don't fly it in much wind ...also remember being 3 channel ground handling at low speed sucks
