Just thought I would chime in here and let you guys know I flew my 118" Bill Hempel Yak with a DA-120 last weekend and with A123 batteries up front it CG'ed perfect and flys like a dream. I have posted some pictures and a video on the 118" Build thread under Bill Hempels web site. Great plane and flys awsome.

Can anyone with the 50cc version tell me what header to use to run a canister muffler? im running a da-50 in mine and my club has expressed their displeasure with my yak running a pitts muffler. ive changed to a carbon prop and thats still not enough to quiet it down. i need to get it down to 96db at 25 feet and a canister seems to be the only way.

I am using a flex header that came with a cheap cannister, so I can just bend mine how I need it. I believe most are using a 25mm drop header though. Also, it may vary depending on what cannister you use. A rear dump with the inlet in the center may be different than a front dump with the inlet at the top of the can.

thanks for the reply VWchad, i was actually going to send you a pm to ask you that question. im planning on running a proflow cannister. i emailed Bill with that question and he said it needs a front dump cannister.

A 50cc engine is alright to fly, but this plane needs the 60. Don't think you'll. Be disappointed |
