I'm awaiting ups for mine, should be here in a couple of days.

Anybody have installation tips for the Revmax on the Cal50?

Revmax

I ran into a mounting issue with this. I thought about drilling a hole in the Brass ring. But instead I mounted the mag. in the fan and glued the sensor onto the fan shroud. I will just have to be careful when removing it. The glue only touches the heat shrink, so it should be fine. This turned out to be a solid way to mount it also. If anyone else has a way to get around the clutch, please post it.

Thanks CY, I'm gonna try the flywheel possibly, if not, I'll try the fan route.

My revmax installed. I avoided gluing the sensor to the heli. Instead, I glued the two brackets together and drilled two screw holes underneath the fan shroud to mount the sensor. This makes adjusting the sensor very easy. I tried going around the clutch, the Caliber50 ain't havin' it.

The TJ RevMax was a breeze to set-up and it definitely works very well. No problems with the way I installed the sensor. I was a bit nervous when setting my targeted engine rpm as this is my first governor/rev limiter, so I started at the lowest rpm setting through my radio and raised it slowly to check the rpm limiter. I spooled up the blades a bit and put in idle3. My throttle curve is 100% straight across board. The limiter was set at 9,600rpm for the engine and it kept it there. I knew the system was working. I set it through my radio for 18,000 engine rpm's which calculates my head speed around 1,750 to 1800 rpm's. I spooled it up and switched to idle 3, the beautiful sound of it winding up to speed, I pumped full pitch into the sky and the rest was fun.

Any input?

I switched receivers to get away from the whip antenna. (short distance disturbance) I could replace the antenna, but I wanted a brand new receiver. (Mine was old),Instead of using a Y, I elected to go with the manual pot. setup. Does any one have the the Pot. setting for the Rev-Max, @ 1900 Headspeed? (Personal Experience For example). More would be apreciated. Since the Rev-Max only limits the highest headspeed, Why should it be Computer controlled? I could set it up for I-1 or 2, but what's the point? It's a Rev-Max! Thanks for your input. Charles.

P.S. My sensor was broken from removing it from the mount, the original mount on a .60.(Very Fragile) New one is installed using the original mount screwed to the fan housing like the last post.

Ok! It was my fault!

It's so you don't blow-up your engine. It controls the engine rpm that leads to a proper headspeed. I set my engine rpm according to the manufacturer specs in the book for the maximum horsepower. Its right around 18,000 rpm. With the main gear ratio, and engine rpm, it sets my headspeed @ 1800 rpm. I've had no problems through 6 gallons of fuel with the way I mounted the revmax.

Ok. Post not read.

Got that, Read the post. I was wandering what the purpose was of using computer selection, instead of just setting the pot? It will limit the max RPM anyway. So I'm wandering the purpose of setting Two different values with the radio. Maybe a slower max RPM in Idle up 1 or 2? I'm looking for general settings of the pot to play with, instead of burning up fuel until I get the right sound (from 1/2-1/1). I don't have a tach, and don't plan on buying one, since it's only used with a new heli set-up.Heli-Cuz, is this the Caliber 5? I don't want to be short, but I also don't want to load up this web-site with extra replys that could slow it down. Thanks, Charles.

BTW: I went with your mounting sugestion Heli-cuzz. Works great.

Ok! It was my fault!

I feel the computer selection makes it that much easier. Yes it is the C5 with the hyper50. I love the revmax, just hearing the consistency of the power output, very smooth.


Don't worry about posting, that's what makes a wesite, you, I, and everyone else that posts. The only thing that will slow this site down is dial-up. LoL

ease of set-up

Thanks for the reply. Ease of set-up is always great. But I'm limited in available outputs. So I was just looking for a general pot. setting. Using the Pot. setting. Is it 1/2, 3/4, 5/8,9/16/,7/8 or any other sugestion. I think I'll just fly it and try diferent settings, since I can't get any input from this website.

Ok! It was my fault!

Ok, here's the deal with the pot settings. When the pot is turned fully anti-clockwise, the target rpm is set to 9,500rpm. When the pot is turned fully clockwise, the target rpm is set to 20,500rpm. The position of the pot proportionally corresponds to a rpm setting between 9,500 to 20,500. I'd say you'd want to be around 3/4 to 7/8 with the pot turned clockwise. Make sure you calibrate the revmax before trying to set your target rpm.

Goodluck, Brian

Ok

3/4 to 7/8. Sounds good. It's calibrated. I started with it @1/4 and it acted real funny on the run-up. Thanks Brian.

Rev-maxx

Man, my buddy convinced me to just go ahead and run a Y off the 8/B terminal. So I recon I will. It will be easier than landing to adjust it. But I still wander the purpose of Two points, if it's a Revmax? Why would I want to limit the Max RPM in normal mode? Maybe so I know it's working before I go Balls out in I-2?

Ok! It was my fault!

Naturally, I'd say a consistent head speed is better than an inconsistent headspeed even in normal mode. The nice option about radio programming is you can set different limits for each individual mode. The pot limits you to that individual setting.
Let me know how ya make out with the revmax.

Ok.

Got ya Kuzz. I was just brought up old school with these heli's. Learn to fly the tail. When I go to fly-ins I see the gov's working in normal and I-1 & I-2. Maybe I'm just wanting to have the satisfaction of knowing I can still set up the heli. without modern hop-ups. I'm going to set up Two conditions with my 9Z and play with them both. I will probably like the Gov. set-up better.

Ok! It was my fault!

Wierd!

Flew mine Today. The Rev-maxx was noticable @ hover when I changed settings from low to high. However when I switched to I-2 It revved out of this world. I need to investigate settings for I-2 in the 9Z.

Ok! It was my fault!

I take it your not using the pot on the revmax unit.

How do you have your throttle curve settings for each mode?

If your revving to high in idle1-2, simply lower the setting about 5% lower and see how it sounds. That's how I tune my engine, by sight, sound, throttle response and high speed in idle3, that's my 100% straight across the board throttle curve with the revmax on.
I always do an autorotation to test the low-end side, if it goes right to an idle, its good, on the other hand, if it races after the throttle hold is flipped, it's to lean and needs further adjustment.

Yup!

Ok, I discovered this evening, since I knew what to look for. When I went to the ATV setting on th 9Z Radio You can set the ATV's for the Rev-maxx. However in the ATV setting you can switch from Norm. to I-1, and I-2, to set different values in each setting. This is good to know. Now everything is appearently ready for Tomorrows flight now. Gee, how learning Fut. from JR is a different world. You can do this with a JR radio, but it's just a different world of learning. Anyone got a PCM 10 and want a 9ZHP? I've been flying JR for 20 years, and I think I might switch back just for instilled set-ups preset in my mind. I think it would make life easier on me. 10 X,SX, SX2 9303?

P.S. Why would you set a Rev-Maxx to Autorotate, that has nothing to do with the MAX RPM? Hence Rev-Maxx.(Limits the Maximum RPM set). Just wandering. Not to dis appreciate, just not understanding what your saying. Maybe autorotate to see that it cuts off?

Throttle hold disables the revmax.

I don't set the revmax to autorotate, I was using an example of how I tune my engine. I use the revmax to test/tune the high end mixture with it in idle3. That gives me the 100% throttle I need to tune the high end, I then fly for a couple of minutes to see if the high end is running to lean or rich. Once the motor is warmed fully, I then hit throttle hold and auto-down to see if my low end mixture is correct with a smooth reliable idle.
The temperature here has been so up and down, I'm constantly making big adjustments with the mixture settings. Richen up when cold, lean it out when warm.
