HI All,
I am a heli instructor at my field and I have begun suggesting folks to consider a Pantera as a great starting heli, especially if they are not set on a small electric. Well, much to my surprise, several folks have taken me up on this and are now asking me for engine reccomendations. Normally, I would suggest either the os 50 Hyper or the YS, but I have heard a rumor or two that the OS 50 has an overheating problem in this heli - Anyone have an expereinced opinion here? - I own both motors and think they are both great, so I am surprised to hear this. The folks I am helping will be starting out, so mild flight is in store here for a while, these are not 15 year old kids I am helping

THanks for your help in advance!

Joe

pantera sucks suggest a frenzy! that being said to help the new pilots on a budget i would suggest a .61 size engine in this bird as there going CHEAP AS DIRT in the classifieds liek 50$ for engine and pipe cuz its a rare size but this heli can support them

The only thing that I have see bad about the OS 50 is they chew up bearings, most Panteras are running them. I never tried a 50 Hyper, but I have had the OS61, OS70, TT70 and a YS 91 in the Pantera. I have a OS 61 in one Pantera and I am messing with a OS 91VR-DF motor in another one. I never had any heat issues with it yet. I am still waiting on a new clutch bell to be made up so I can get back with this one again.

I did have problems with my OS70 and heat, but I had major carb. issues on that motor I never did get it right B4 I warped the crank. Others are running the OS70 with no issues. But if you can find a good 61 I would grab it, they run great in the Pantera.

You have some nut to read this post in the Audacity section, bash the Pantera then suggest a different Heli? I have read your various posts for the last month and I see you as nothing but a sh%^t stirrer and a trouble maker. This is the only comment I will make about this so do not look for an argument from me. I just call it as I see it.

No heat issues as I know with the Pantera, I run the Hyper 50 motor. I fly in Sacramento; last summer flew the Pantara in 105+ air temp. I was the one who was overheated.. Tell your students great air ship, set the Pantera up in the mild side on the Bell Hiller and the inside hole on the seesaw arms. Basically go opposite of the Pro Tips on 3D flying. Maybe even use some flybar weights.

I have a student I am teaching TIVOPRO who posted his build here. He loves the Pantera as compared to his Hawk Pro and T-Rex 450

Above all have fun, I love watching people learn to fly. Feel free to contact me for anything in the future

Your compassion for newvies is appreciated, but the Frenzy is a better solution for stick banging 3D, where areas the Pantera is more stable platform suited for learning out of the box.

As for engine, any 50H will do fine. Bearing problems are prevalent for folks who are either over revving, have runout, have unbalance issues, or run the engine on the lean side.

A 60 in the Pantera is great if you happen to have one laying around in the basement, or a 90 if you fly at high altitude or you happen to be Mr.HillBilly. LOL
Otherwise, for a beginner’s heli, any 50H with the Audacity muffler will do just fine.

Joe,

On the heli side I've only owned OS. 2 Hyper-50's, 1 OS-32 and an OS-37.

At a point in '06 & '07 I had the Hyper 50's in the helis discussed here.

I have in the range of 120 gallons between the two and NEVER have had an overheating issue...not once even at ambient temps in central Indiana reaching 95F on the flight line.

The engine with the most hours is now on the 4th season and on it's 4th set of bearings and 2 piston ring. All on WildCat CY-30%.

Suggest the OS-Hyper 50 and feel comfortable with it. The engine is reliable, starts, idles & transitions well.
When coupled with a good tuned muffler and setup correctly...it makes great power!

P.S. If your Hyper 50 begins to "growl" and the idle is inconsistent...that's the bearings "speaking to you"...about once a season seems to be my MTBF.

Dale...curious if you have my other Hyper 50 in the air in the Tiger I passed you way last year?

lotta ins, lotta outs

Zero and I mean Zero heat problems with the hyper 50 in the Pantera. If there were issues I would see them quickly - Columbia, SC has 100-105 degree days for a long stretch in the summer. I also have a Pantera with the redline TT motor in it and zero problems there either. From what I hear the guys on here doing the bigblock conversions have little or no issues with heat even with the .70 and .90 motors. just my 2 cents. I'll go back to sleep now.

Tiger w/Hyper 50 (formerly owned by The Dude II)
The Dude II,

I have put about 3 gallons through the Tiger with no issues. I received the Tiger w/ hyper 50 from you, looked it over, put my radio Rx in it and took it to the field and she started on the first try and I havent touched the needles since.

I have owned OS 50 SXH and Hyper 50s and would suggest the OS engines for ease of operation and low maint. Its to bad that OS ceased production on the bullet proof 50 SXH as I believe that was the perfect heli motor for beginers as well as scale applications.

The OS50Hyper is the SAME engine as the OS 50 SXH. The hyper has a much better carb without the lean flatspot the SXH had. Ah, and a pretty blue head. Did I forget to say is pretty? , I hate bling.

In 4 years and about 30 gallons I had no bearing problems with my 50hyper, and I run it like a stole it! but never lean!
I change bearings every season or 10 gallons. The OS bearings lasted the shortest. Bearings from RC-Bearing.com been very good to me.
