I was thinking of going with the BH Hanson Zenoah 29 RC 3D MAX and tunned pipe set up. I used them before on my boats with great results. They were fast and reliable.

Toxic 270's here. I tried the Hanson 290 and went down in cc's to gain head speed/engine rpm's.

Quickdraw seems to have the hot tuned pipe right now, it has been run on quite a few 270's, but not 290's from what I have seen. If you want high head speed/engine RPM, the 270 will be better, if you prefer lower head speed/engine rpm's, then the 290 is better. Gassers are a different animal, just throwing in the biggest engine does not guarantee the best performance.

The Quickdraw has to run in the high 14,000 range at 2150 HS for it to produce max power. If that is not what you are looking for, then a muffler would be better.

Im just starting to test the Quickdraw on TRM's new 29+ stroker... Mitch and I both think after flying a few gallons through it with the RJX pipe that it has the potential of being a real Beast on the Quickdraw... we shall see....

If the Quickdraw can shift the powerband of a 290+ higher, we may have a new powerhouse winner. When I tested 28.5, 29.5 and 30.5 with V2 mufflers, they all made good power in the 13,500 and lower, but did not like to rev over 13,500.

Thanks for the info guys. I'm leaning towards the BH Hanson because I had good results with them on my boats years ago. I'm hoping I'll have the same results on the heli. Thanks again.

The motor
I'm using a BH Hanson G270RC motor with mine with the Century v2 pipe. Makes great power for me and flies very well. I don't really need that last ounce of power so its a real good setup in my opinion. I run headspeeds between 1650 and 1900 on mine with good results.

Fast

Flex lengths have a great effect on how the pipe performs. Have you tried longer than the 4 inch flex on the 290? In the boats. The bigger motors liked the longer flex setup. Porting on the engine has a big effect on the area the power works at too. I get customers sometimes that have low end motors and put top end pipe setups on them and vice versa. The packages and setups need to work as a whole.Running shorter flexes will raise the rpm and range it works in. Same as going longer helps in the low to mid range but suffers on the top. So going to a shorter flex may help on the 29 setup to rev more on the top and shift the power band higher if that what you are looking for? If not? I would run a little longer on it.

Todd - yes we have discussed this before and I have tried 4", 3 3/4" and 3 5/8" flex. The engine did not "wake up" until it had the short flex length. The engine is a Toxic G270TT engine. I have talked to Doug and he has had a similar experience. If you want all out power it is fantastic. If just cruising around then a standard muffler is better and cheaper.

For me, it does not make sense to spend $300 on a pipe and limit it's output with long flex couplers so the performance is similar to a standard muffler. Either you want the HP or you don't.

I no longer have a 290 to test with, but depending on how Doug's works, a pipe may be just what the 290 series needs to let it rev and still have respectable performance at lower rpm's.

I've got a BH HANSON 270RC and couldn't be happier with it. Runs very smooth and makes plenty o power.

power,
keep the fallowing quote in mind at all times, it applies to all helis, all brands and all pilots at all times

(quote) ""The most impressive aspect of flying helis is the ability to make it seem to perform much better than the norm. A new product is introduced and a very capable pilot and a good video person that can edit and manipulate slightly the video ,,,but more important the pilot really has collective mastery can make a dog look like a million. Then you see it at the field belonging to Joe Shmoe...and he is bogging it.""

Same thing I deal with at work all the time. One customer has his motor setup perfect and it runs killer. The next guy who gets it and seen the other guys run. Buys one. Tries to run it than complains product is junk. When it was his setup and not the product. Bad things about being manufactures. You have to deal with both sides of it. The ones who love it and the ones who do not want to get it setup and just complain about it. Because they do not want to take the time to get it setup correctly. I had a guy call once that had another manufactures setup. He called to get ours assuming if he stuck it in it would run like all the fast guys he has seen. When I asked him how fast he was running and he told me. I told him with the engine he has he is 20 mph off the mark on his setup. You need to get an understanding and learn how to set things up than add the additional power to gain. Throwing more power might get you a mile or two faster BUT not the massive increase he figured he would get going to ours.

Fast

Please note. I am not saying anything about you or you can not setup something. Please do not take it that way. I am just saying what seems to be the norm sometimes.

Todd - I think the Quickdraw is fantastic, not only in power but also quality and durability. I have also heard of pilots that are still at the basics of flying that are trying to use them. For the right pilot, the QD is the answer. For someone starting out, a muffler would be a better choice. It is acting like any tuned pipe I have run on two stroke motorcycles, they have a sweet spot and understanding how it works is important to being successful with it. It would be great to try it with different port timing, but that is not an option most pilots would have.

But come one 300 for a tune pipe, to much I think, the whole new engine unmodified 250

Buy the pipe kit and weld it yourself and save than. I paid 205.00 for my pipe for my nitro heli and it smaller. Also you say unmodified engine. Exactly. Add in the engine tuners time and labor into it and price goes up. So in theory it is no longer a 250.00 motor. Unless you do all the work yourself.

205 for a nitro, the best pipe I have for my OS 91 hzr is hatori 21 which almost 210 ready to use, well if the price decreases to 200 ready to install that will be better to me, I an very happy with my torpedo v2 gasser muffler 130

Engine was delivered today. Looks great can't wait to start breaking it in. Anything better than Penzoil 100% synthetic TCW3 oil to break it in? That's what Hanson recomends.
