Hi there,

Im getting together a tiger 50, recently persuaded across from getting a raptor.

I do want to use a Thundertiger 50 engine to begin with though to save some money- Im a begginer and dont want or need the power of the hyper.

Will this engine fit ok in the Tiger 50, or do I need some kind of adaptor. If so, where can I get one?

thanks

I know some people have decent luck with TT motors, I have found them finicky and being new your time would be better spent flying, not tuning. Go with the standard OS 50 or 46 if you want to save a little, the 50 can be upgraded to a hyper in the future if you care to do the upgrade.

Good luck

Just remember -- if the world didn't suck, we would fall off.

The TT 50 should fit just fine.
Has it been run before and broken in?

I have no personal experience with the 50 but do with 36 and 39.
Flbarless is right about them being finicky.
If you a patient man you should have no problems with it.
As you move up in the learning curve I'm sure you'll want to upgrade.

Just go and have fun,

Jim

tt50
iv'e got a hyper in one and the tt50 in the other and both engines for me were easy to tune actually the needle settings seem to be pretty close between the two. the hyper does make more power on the top end, but my tt50 isn't far behind with both running cp30. for the money i don't think that it was a bad engine to purchase. although there are horror stories on the tt50, there are stories floating around about the hyper also. i think if you are patient on the first start and through the breakin process you cant go wrong with either engines. i would by both engines again if i had to. brian.

Hey thanks Brian!

I ordered the engine from heliproz under their supersavings, its opsn box from kits they split up when they run out of raptor kits without the engine.

It was only $90, and then I bumped it up with some trex parts I needed to 104 so free shipping!

Im still learning and almost got a raptor 30, but the tiger just looks so much more solid, and its the same price as a raptor 30!

Ive heard the TT50 is more fuel efficient than the os 50 regular and hyper, so Im hoping it will be a good compromise for a budget begginer rig.

Im just not sure if it will fit the standard tiger 50 motor mount, maybe I can ream out the holes a bit or something.

What did you have to do to get it to fit?

thanks

will

The TT 50 should fit any thing that the OS 50 fits in. It should be a drop in fit. BTW, did Heliproz have any more? I'm looking at a Tiger or a Caliber for a 50 size heli this spring and I've been spoiled by the fuel efficiency of the 30's and 40's I'm running now.

I was also thinking of the TT50. I did see this though so it leads me to believe that it is not a direct replacement for the OS as far as mounting hole location goes. This is a direct quote from heliproz
The TT50 is NOT the same mounting dimensions as OS, requires the TT mount for the Raptor 50 . WARRANTY BY ACE HOBBIES ONLY
I just wonder how much of a power loss there really is between the TT50 and the OS 50 SX-H NON hyper

engine fit
i have both the tt50 and the hyper in two different tigers and both engines are on the factory supplied motor mounts that came with the tiger. be sure to order a prop washer with either engine that you buy as you need this item with the tiger. john beech does have an alternative product that is a "long" hub that replaces the stock length clutch/fan hub that you can purchase for an addidional 20 bones. as far as power between them during normal flight aerobatics you wont notice much if running similar muffler setups and proper pitch/throttle curves, but when you start doing heavy 3d you will notice that the hyper does give you the advantage with more mid-upper range torque to pull the pitch. fuel consumption seems to be pretty close between the two as far as i can tell at this moment but is seems that i can fly the tt50 an additional few tricks before its time to land. keep in mind that i am using cp 30% and os#8 plugs with my setups and that is "3d" aerobatics that im flying, at least thats what im callin' it! i know that there has been some negative floating around with both engines and i might have just got a lucky pair of engines, but for me both have been excellent runners. both are running "revolution" brand 50 size mufflers, but my new audacity hyper muffler is being shipped to me today so we will see how much improvement that makes on the hyper. i know if you take the time to setup the curves and mixture correctly on any engine and allow some time for rich break in, any engine should perform for you. i do break in my engines by hovering the first tank rich and landing often for a few seconds at a time then i fly the second tank on for the remainder of the gallon the way that i am going to fly the chopper the rest of its life. this has worked for me with any engine. i dont believe that any other breakin procedure is necessary, but thats just my synopsis. just remember "lean is mean, but rich is where its at". a quote from my racing days.brian

TT 50 and Tiger...
Last night I was looking through the Tiger pdf manual and I believe that it states in there that the TT 50 will fit the motor mount that is supplied in the kit and ditto to B.Hofferth for the info.

help :(
I am suprised that the motor mount in the tiger 50 kit will work with either engine.

I did some research and it seems TT50h engines newer than two years old have a 42mm engine mount spacing, older than two years and they have a 44mm spacing same as os engines.

Hence new raptor v2 kits come with two different engine mounts, one for the os50's and one for the TT50's

thread here http://www.runryder.com/t190982p1/?...t=tt50+mounting

Am I correct in assuming that the motor mount in the tiger 50 has a 44mm engine bolt spacing?

If so has anyone managed to, or have any ideas how to make a new TT engine with a 42mm bolt spacing fit the tiger motor mount with its 44mm bolt spacing?

Also, can anyone give me a link to the type of prop thrust washer I need? (not familiar with what one is or what it does)

John, as the designer of this machine any ideas how to make this work?

thanks

Will

You are correct in that the TT50 comes in two mounting bolt spacings. I too was thinking about getting the TT50H listed on Heliproz site but was worried about it fitting in the Tiger 50. I contacted John and asked about this. He said you could elongate the mounting holes to mount the TT50. After talking with him though I've decided to go the route of getting an O.S. engine. Now I have to make up my mind whether to go Hyper or not.

i myself was unaware of a change in the tt50 engine mounting bolt spread, so i measured mine and it is indeed 44mm the same as the hyper in the other bird. so i must have an engine that is older than 2yrs old which would be correct since my receipt says that i bought it 3yrs 2mo ago. i dont think that i would sweat it on opening up the holes a bit to make it fit. i would just drill them out the next size up that will allow them to clear the screws, but thats me. the part # for the drive washer for the tt50 is PN0023 this is what my engine manual from ace says. i dont have the part # for the hyper as i threw out the package, but i do know that it is on the heliproz web site if you go to the engine section and do a search. i think that you can put a square peg in a round hole if you try hard enough though, we had the technology to put a man on the moon in the sixties so i think we can make a tt50 fit a tiger motor mount.brian

I do not have a TT engine but I am familiar with the Raptor engine mount. If TT changed the 50 then I can understand why you would need a different engine mount. The Tiger has slots in the side frames that allow you to slide the engine up and down to get the proper clearance in the clutch bell. The Raptor is NOT adjustable in that respect. It has holes instead of slots. That is what I think they are talking about by needing a different engine mount.

But of course I am wrong. I checked out the other links listed in the thread.
I find it weird that TT would change things in the middle of it all.

willard, jim, i guess i learned something in this thread also, i don't know what they have to gain by altering the mounting centers? other than to frustrate people even more. its hard enough to fly these things as it is. brian
