Tower Pro 70cc 4-stroke

[Terryscustom]

Well, I saw a thread some time ago on "the site that shall not be named" on this engine with the typical bench warming engine experts all chiming in. So I decided to be a crash test dummy and get one. I caught him just before the china new year break and he had a super "introductory" price I could not turn down. Delivered to my door from the opposite side of the planet in four days for $48!!! http://torqpro.com/?product=tp-70-four-stroke-engine

I don't intend to start some huge thread on this but I know I'll be shooting some videos and trying some different props just for fun. I will be installing this in my Top Flight P-47 with a Biella 20x10x4 scale warbird prop.

Quality looks extremely good, nice casting, heavy duty stainless intake manifold. They say "muffler" but it's just a flexible header. I don't have room for one but first thing I thought was that this would sound so badass with a proflow canister!!!!

Looks really cool and would love to hear it run. I know DA had that little 4 stroke which also looked nice but I never heard that run either. Hope it works out nice for ya.

I stopped by today and took a look at this thing. Wish my pockets were bigger so it would have fit in one and it would have disappeared from his shop.

There are videos of it flying on the link Terry provided. It sounds awesome.

I just can't see it being that fabulous for a 3D plane but for scale flying in a warbird, or civilian scale it could be way cool!! Cub? Decathlon?

Looks like a nice motor. Has a 120cc twin also (60, 35, too) for 550!? Hmn.....

Well, I built a test stand today quick and fired this badboy up. It started pretty easy and subsequent starts were very easy. The sparkplug cap BARELY fits on, but it looks like this thing will fit my P47 cowl very nice.

The problem........The thing sounds like a crappy scooter with no muffler!!! The straight pipe is nothing short of obnoxious. I had a muffler on the shelf for a DLE 120 and in redneck desperation (knowing it would only last a minute or two) I duck taped it to the end of the flex tube. AAAAAHHHHH, it only lasted a minute but sounded SOOO much better!.

So now the trick is going to be trying to fabricate some type of muffler for my P-47. I wish @Tseres was closer he can make anything with metal and if he can't he knows someone who can. So, I'll get my plane to the shop and get it set up so I can work on it and maybe some of you awesome GSN people can help a wood guy make a muffler?

Terry, I have had great luck with Al over at JTEC.
He has made a couple different customs for me and at around a 100 bucks it hard to beat.
Good luck and cant wait to hear the old Jug rumble!

Terry; Drag it out to this side of the state and I will make you what you need.

There's an idea! All the flying weather is over there too! I'll get the fuse to the shop and maybe mount the engine to see what I've got to work with.
