Default tuned pipe and header?



not sure where i should have posted this, sorry in advance. ive got a sig wonder and just got a k&b .18 to put on it. my question is do you know of any headers and tuned pipes that would work well with this combo. i guess i mean overall fit on the air frame and performance from the engine. thanks

Macs products lists a header for it.

I don't have any hands on experience with this engine, but the only reports on it I've heard say it isn't a real screamer. The cost of a tuned pipe might not justify what you get in return.

I could be wrong, but I think the "K&B" .18 is actually a Toki? I think it's the same basic engine as the car and ducted fan version?

It's possable that this engine needs a small prop to let it wind up...so maybe a pipe would really help it? (just specualtion on my part here )

i dont have alot of experience with small engines. so i kinda looked around and read manufacturers rated outputs for power (i know its a crap shoot) and they seem to be comparable to much more expensive engines. is there a better option for a sig wonder? or is this motor for the $40 i paid going to be a perfect fit?

It's a .10-.15 sized Sig Wonder? If you can get the CG right without mass amounts of lead, that's what counts.

".15s" are real versatile..you can stuff them into real small designs or they will pull around pretty large stuff [like SSCombat planes] just fine.
