They have talked about one and a 90 as well. However like anything else, they are probably watching to see how this new motor works out. So far so good on the thirty which is the largest market. A fifty from them sure would be cool. I could only imagine.

Hello Jeff, I once talked to a Hirobo rep who was very knowledgable and sharp on Hirobo products at Zoom hobbies. He explained a lot about the performance & reliability & QC control of the newest offering of engines. With reps as good as him, I would not delay in purchasing one in the near future to try out on one of my new projects. :)

Thanks
 

That's really cool. Eric is a great addition to the team. :)

How does the power to weight ratio comparison of OS to Hirobo engine for 30 sized heli?
I keep hearing great things on Hirobos engine, might be getting one.... ;)

Hirobo .36
 

The rpm's are higher first off and the power rating is that of a 40/46 in a thrity size case. Really it is a ton of power for most 30 size machines. For example, I need to stretch my Shuttle Plus to handle the motor 100%. This is a good thing for aerobatics. Honestly I cannot say how it is power to weight ratio, but it is smoother than the OS and it is definitely stronger. Most oweners will agree.

Sounds like TNT comes in small packages! I'm going to buy one possibly in the first of November to replace my Shuttle ZXX's OS 32 F motor. I have 4 ZXX's counting my wifes. I need to try your newer 30 sized Hirobo Scedeau soon.

Cool,let me know if you have any trouble. The Sceadu 30's will be going on special next week. About 50.00 less than now. May be a good time to grab one.

Check around.

Thanks

Jeff - Ibought some parts for myused Lama from you on Wednesday; HNCANTOR;

I was wondering about the shake problem I had. I have/will do the following:

1) replace rubber dampers
2) clean & regrease blade holder bearings
3) put on new set of 550 symmetrical blades, properly balanced
4) replace beat up old muffler
5) check main shaft and replace if needed
6) spindle looks okay

Is there anything else I need to do?

ALso; has os 32H engine, used. On spool up, it quit several times as I tried to take it past about 60% throttle. I had throttle about 4 turns out, running rich, tried it leaner, same thing happened. Has a new plug in it. I removed engine, replaced the carb gasket and retightened the carb screws while pressing down on the carb. Engine looks okay, no head leaks & compression is good. I'll try it again tomorrow. Is there anything I am missing that isn't obvious re the high speed cutout?
