Hi, I am looking for big gas helicopter running 30-50 ccm engine.
Do you know any reasonable priced sets or at least mechanic stuff to build one?
It has to be able to take 1-2 hour flights.

Thanks, Mark

The Rmax might fit the bill, but you better get your cheque book out, they aren't cheap.

These guys have some interesting ones

If you look at their Industrial Twin,(Twin 26cc Zenoahs) then they state it can carry a 25 pds payload for 30 mins.
If that payload is used for fuel, then I guess that it can run for a lot more than 30 mins......

If I look at runtimes for my Zenoah powered RC Car, then I will guess at aprox 1 hour/liter pr. engine.
25 pds is aprox 12 liters of fuel, in my very unscientific calculation, then that should give you at least 6 hours flight time.

I have never built nor flown any RC Heli so I can't comment on any heli makers quality

zacko

Wow those things are huge, I could fly my dog around with one of those. Probly not a good idea thuogh.
