O.S.Engine PowerBoost Pipe - 105HZ

OS powerboost pipe makes great power for the OS 105hzr. Great service and shipping from HeliDirect as usual!

Had to have it for my OS 1.05 Dominator 700 build. Baulked at the price, but once seen, it is a jewel! Polished and sturdy, accept nothing less.

Don't use anything but this pipe for your o.s 105HZ/HZR. I tried several on my trex 700N, out of all of them this was the best fit, and best looking. In addition to the looks this pipe performs flawlessly! My engine has never run so good, easily tuned properly and runs more consistently than it ever has. The weather changes day to day where iam at so every day can have an affect on running and tuning. Yes the price is insane considering you can buy an fpv racer, or small BNF Heli for that price! But now having owned one, I'd buy it again at the same $. Don't waste time and money like I did, just get the best now!

I recently got into nitro and read up on what would be a good setup that is easy to tune/maintain. I ended up with the OS 105hzr and the OS PowerBoost pipe. It's a great matchup and my setup is running great.
