lgodin-RCU,

"Not true, the Roto 35 is measured as all up wieght 3.8lbs WITH ignition and muffler, the Brison 2.4 is measure on the site as 2.75 bare. I had a brison 2.4, it tipped the scales at just over 4 lbs with ign and muffler.


FYI, this plane should have a MVVS 1.8 gas or similar "

On what do you base your info? Do you have one of these planes? I do so I'll tell you what: You post pic's of yours and I'll post some pic's of mine, including the engine which weighs significantly more then my ZDZ 40 which weighs more then my friends Brison that comes in at 2.8 lbs without the muffler.

I think his muffler weighs all of 2.5-3 oz. so it's still lighter then my Roto. I'm not really one to get into a *&$%'in contest with people on msg boards but I do get kinda tired of always hearing "you gotta do this" or "you can't do that" when it comes to these planes, 'specially if the guy on the other end doesn't even have one to use as an example. Everyone told me I couldn't use a gas engine on the Sig Extra I built and now everyone that see's it fly is just amazed at how well it flies and how easily it lands. Sometimes it is easier to just watch and see rather then jump to conclusions. I may make suggestions and recommendations but I don't think you will ever hear me tell anyone that there limited to three choices of engine for anything.

Mudspike, if you have the Brison, try it if you wanna, don't if you don't wanna. Or maybe put a fuel guzzleing glow motor on it and fly it that way. Your plane, your choice and your wallet. For that matter, buy two and try both ways. I got a buddy building one with an OS 1.50 and another flying it with a YS 1.40. Still a 3rd is flying it with a big thunder tiger engine. You'll never know 'till you try.
