I am happy as hell with my new THUNDER TIGER 53h REDLINE ENGINE. I decided to give this engine a try after my OS 50 Hyper reached the end of its life. I was very skeptical with regards to this engine as a fellow member had one and it didnt sound good at all, it had a very distinctive leany sound to it and hardly had any power, so it was bogging easily.

So now i had a desicion to make, do i buy another OS and suffer with back bearings which fail every 10-15 flights and suffer a rich to lean issue after half a tank has been used. Or do i buy a WEST 50h Engine which has plenty of power compared to any other 50 engine seen to date. Well i did have one of these engines before and they do have the power without question, but do seem to be quite picky with regards to carb settings and as i wasnt that good at setting engines up i struggled with the settings, so i sold it with an old model. I had also seen a Ys 50 engine fly at my club and that seemed gutless and had a very high pitched whirling sound to it. so that engine was out of the question.

So after reading virtually nothing but positive feedback on the THUNDER TIGER 53h REDLINE ENGINE on Runryder (Virtually, meaning apparently some people were experiencing "sticky carbs", meaning after a couple of flights the carb would lock up) i decided to go for it, knowing that it could be a total flop and end up costing me more in the long run.

I installed the engine and fitted the Muscle Pipe 5 which i previously had fitted to my OS. I ran it rich as hell for the first gallon and a half on 30% Wildcat LDV Fuel, then leaned it off a couple of clicks at a time.

After nearly two gallons of rich running i asked an experienced pilot (Simon Brown) to help me lean the engine off. After a small amount of tweeking and a few changes to the throttle curve and govenor the engine was running sweet.

After serveral recent flights the engine is honking big time and seems to be developing more and more power after every couple of flights. I have not found any issues with the sticky carb, Nor have i had to change any settings to the carb from a previous flying session meaning the carbs are consistent. The engine also delivers consistent power throughout the tank.

Overall So far i cannot believe how good this engine is, i really do hope that it stays consistent and keeps developing power, but also keeps that back bearing well lubricated prelonging its life.

So far it is definately an OS Beater, IS IT THE BEST 50 ENGINE ON THE MARKET?

Happy to hear that your TT53 runs nicely.
If I wouldn´t have bought my west50 for the Rex, I would have got the TT53 instead.

The thing about the carb is that TT used a weak material inside it, that issue is now taken care of and I hope that you´ve got your hands on the "new" edition.
Every engine produced since 2008 1/9, has the new carb.
I could describe in detail about what TT have done to the carb to improve it but that have to be done in swedish, in english I wont even bother to try going in to the technical terms... smilie

Hope to read of your progress regarding the TT53, cause when my TT50 on the Rappy brakes down, I will definately replace it with the Redline (.onthephone.)
