if you are talking about the cone pipe in the link I would just buy a gasser plane pipe inside the US with the same dimensions, but I wouldn't buy one unless top speed is all you want

give me a few and I will try to find you the quick pipe sold inside the US

You not going to find a gasser airplane pipe with the same dimensions. The pipe gives you a broad power band NOT top end only. Unless you want to shorten the flex for more top endpower? Doug did it on his Whiplash because they are running higher head speed and are turning the engine up in rpms and wanted the additional power up there.

Gas Parts Plus and Gas RC Products do sell our pipes too. The kits are bought and welded up by someone else for them. If you have the setup to weld? You could buy the pipe kit and assemble it your self. If it is bought elsewhere than us? DO NOT get the internal silencer setup.
Please note: we recommend the 6 inch silencer to quiet it down. Some guys run the 3 inch on them but if you have the room? I would recommend the 6 inch on it. Some guys even run the 4.5 inch ones and it helps also. I would just try and get the 6 inch silencer to work when installing it.

I have been flying the Quickdraw for a few weeks, I completely agree with the 6" silencer, it is still louder than a V2 even with the 6" silencer. The 4 1/2" was too loud for my taste. It really came alive when I used the same length flex coupler Doug is using and cranked the engine up to 14,800, it falls off quickly at lower RPMs and turning 15,100 did not seem to gain anything.

There is another welder that is assembling the Quickdraw and has a very nice package ready for heli's. You do need to make one bracket to attach it to your heli. He even had some in stock when I ordered mine. PM me or Doug and we can send you the contact info.

Before buying the Quickdraw, I tried a Gizmo internal silencer pipe and was not impressed.

It takes more experimenting to get any tuned pipe set up compared to a muffler, but if you want more power, it can be worth it. If you go with a Quickdraw, I would suggest ordering a few different length flex couplers so you can decide what length is best for you. It also helps to install a longer coupler to get the carb needles close, then install the shorter coupler if you are going for max power.

Due to a heliproz gift card. I am going with the toxic 270 motor. I am not sure how the Hanson pipe will work on this motor.

The BH Hanson tuned pipe will work on any engine if you get the right tune length and needle setting as will the quickdraw.

Like fastflyer20 said.It takes a little experimenting to get the right tune length.

Fast
Did you try just upping the rpm of the engine and leave the same flex in it? Also not knowing what gasser setup you are flying. You could gear it lower so the engine will rev better on the top and still keep the same recovery if needed with the pipe. Or. You could gear it taller and use a longer flex to give you the power in the rpm range you want the engine to stay at with a good recovery. Either way may work depending on the rpm range you want. The pipes we do have a gradual fall off if it is not to short on the tuned length. You can get them pipey though if too short on tuned length. Meaning like an ON/OFF switch. Would defeat the purpose though by screwing up the power band.
Keep in mind too that the engine power band it was designed to run at with porting has an effect on how it recovers and runs also.

Yes more testing for sure, weather is not the best now. It is on a Whiplash, only one pinion is available right now, another one should be released shortly. If the engine was built from the start to run a pipe, Al would have used a lower exhaust height. It just really woke up at the higher RPM with the shorter flex and I suspect anyone with a Toxic 270 tuned for a standard muffler would be in a similar situation.

In running a stock Zenoah in some classes in the boats. I tell guys to use a shorter flex to help in getting some rpm's out of it in the top end. Reason is the stock motor will have a lot of torque because of the lower exhaust timing and can kill some of this off in exchange for some more rpm's on top end. At the same time though it is a balancing act of what you need. Always tough decisions on what is needed and what is able to get and still be usable.

One advantage we have in the helis versus the boats is the variable pitch of the main blades. In the boats you have to have a pipe that can launch from the shore. Pull through the corners and still have a good over rev for top end. Like I told someone on another forum. Helis are like having a 5 speed tranny in your car. In boats we have basically one gear only. So it makes a pipe and porting really important.

Weather has not been the greatest, but I finally had a chance to fly a V2 vs the QD with a 6" silencer back to back, in the air they seemed very similar on noise, which is a pleasant surprise since the QD is running at a higher RPM.
