700N Engine help PLEASE!!!!

exhogflyer · 05-02-2012, 08:44 PM

Ok guys, SOMEBODY has done this or maybe can help me! I want to convert my 700N to 4 stroke power, I don't do 3D so I'm not concerned about less power just longer run times.I'm thinking that a YS 120 or 140 4 stroke may work size-wise, and I'm hoping......but not sure.....that the crank ends might be close enuff to be able to use the stock fan and adapter, at least with minor mods.I can't find any conversions except for Zenoah and clones but have heard of these available in the past. ROUGH measurements from YS factory specs seems like it shouldn't be difficult to mount them width -wise.I think I can modify the shroud to fit, and some minor tweaking may be needed to fit in the frame.I plan on using 800 size tail and main blades so the lower headspeed should not be TOO big of an issue.Can anyone offer some more help? Parts or info? I'm sure there has been some dabbling in the past in this conversion, so one of you more knowledgeable HF's maybe could help me...
THANKS!

I thing gasser is your answer. Any way the ys120 is a two stroke not 4 stroke,

Well, I thought about a gasser but I'd rather a 4 stroke unless it can't be done.YS does indeed make a 120 4 stroke...the 120SCH

I don't think YS has a gas heli motor in production. At least they don't offer it on their web site.

It has been done but I can't direct you to a thread!
You could wait for this http://www.os-engines.co.jp/english/...newsgt15_e.pdf They claim around 60min flight time for 600ml of fuel!

Well, I've pulled the trigger on a Helibug conversion using the G230RC Zenoah, the "Mercury 800" kit.Looks real good, can't wait to get it up and flying! Proven conversion, will give me the long run times I was after. I'll post updates as I go along. Thanks all for the help!
