Hi all, I have purchased a OS 50 Hyper from Heliproz for my Raptor. I am very excited!!! I have a couple of questions about it first:

1. I have the Hatori SB-5RS Muffler. Can I use 30% Nitro with this engine/pipe combo safely? In our altitude we all use 30% on all our machines, but I keep reading posts saying to use 20% or lower.

2. Will this motor bolt up with the motor mount that comes with the Thunder Tiger 30 to 50 upgrade kit (TTR3807), or do I need to but a different motor mount?

3. And last, do I need to make any mods to the raptor to get the motor in. Any tips/tricks?

Thanks, Jim

you will need a diffrent mount. A friend of mine on here just did the same thing. I am not sure of the part number but you can call heliproz and get one. I run 20% coolpower and the stock TT muffler and great power with the Hyper engine. This engine rocks, I could not imagine the power with a MP2 and 30%. no mods to make unless you have the carbon baseplate then you have to shave off a little for the new head to fit

The mount that came with the 30 to 50 conversion kit will work with the Hyper as it's the same crank case as the 50Sxh. Use the 30% with that motor/pipe combo and it will work just fine at our altitude. Run it at 1.5 turns out on the high end and the bottom left at factory settings and go for it. Great power. If you want even more power run a MP2 90 pipe or wait for the new 50 Hatori pipe that JK has been working on. Hope this helps.

Regards,
Eric K.

I think that the mount that comes with those kits is for the TT 50 not for the OS 50.
