I went to install the mufffler on my tower hobbies .61 installed on the TF Piper Arrow and it's not close to fitting within the cowl. Tower recommends their .61 engine and I purchased the recommended muffler. They know tell me that the Bisson muffler should work but I'm not sure that it will. Doesn't seem to have enough room under the engine for the muffler especially the way that the muffler is designed. Has anyone built the TF piper arrow and if so what engine and muffler combo did you use. Any sugguestions would be greatly appreciate.
Thanks
