Any experiences with inexpensive ASP S52H engine and RJX 55 pipe or HK pipe are much appreciated.
My final goal is putting the new version of OS gasser in it after hearing from real people about their experiences. In the meanwhile, I would like a flybar heli with the ASP engine.
Thanks

Cheap heli motors are an exercise in frustration. They skimp on carbs, and that leads to either bad mixture control, or bad RPM control or both. Best bet on a budget is an Align 50H and don't look back.

The Align is a great engine. +1

Also a good Thunder Tiger Red Line.

I have used both and you get A LOT of bang for your buck with both.

The align is a rebadged OS, which has a good carb, thus making it an enjoyable engine to own. Just expect to maintain the rear bearing. The TT 53/56 engines have terrible carbs. Do some searching on the subject if you want to look into that can of worms, as it has been discussed greatly. A wonderful combination is a TT engine with an OS carb, but an adaptor must be fabricated. With proper resources and skills the payoff is WELL worth it. The TT engines make great power, don't eat rear bearings, run smooth and reliable (with an OS carb).

Ultimately, a crossbreed combination is the winner.

Another consideration would be a stock align motor that will be flown until the rear bearing needs changed. At that point sending the engine to Magnum for a center glide bearing upgrade will put an end to rear bearing problems once and for all. This route is actually easier and cheaper than the TT engine with OS carb modification.

Enjoy things that money can buy IF you don't lose the things money can't buy.

There are always good deals on used OS 50 Hypers, YS 56, YS 50, OS 55s over in the classifieds here. Mufflers, too.

Hope you enjoy working on motors.

I'm running a Redline 53 with Thunder Tiger pipe in my X50. It's very good so far. New Redline 56 is only $230. Using OS carb and it's super easy tuning. Not the ultimate in power, but not too far off either. YS60 makes more, but much more tempermental.
