Very happy to announce our new 70cc four stroke 3D-fly gas engine TP-70 TorqPro Gas Engine..
If you are tired fly a two stroke gas engine then our TP-70 four stroke gas engine will be a good choice for your 3D-fly. TP-70 engine has a powerful output and smooth torque line. MAXmum 6600 RPM at use VESS 24x10 propeller.Output response very quickly and very line output. This engine also can use on 50cc-100cc scale airplane ,because it has a very sweet engine sound and very small size to mount into a small engine room.

What does it look like, any pictures? Any specifications, weight, size measurements, and so on?
What is the suggested retail price? Any dealers for it? Where can you buy it? |
I did a couple of internet searches for this thing and other than this single post it does not exist.
|
Notice the OP has only 1 post. Shameless plug is what I see.
|
I wonder if this is that 70cc engine that someone made from using a motorcycle engine. It runs OK, but weighs a lot though, something like 4.6kg.
Not sure about power either. http://www.amr-rc.com/images/produits/OHC_A70.jpg |

We need a few time to prepare for this new engine launched.
We will announce on this forum. Please pay attention to this forum. http://www.rcuniverse.com/forum/atta...mentid=2041169http://www.rcuniverse.com/forum/atta...mentid=2041170http://www.rcuniverse.com/forum/atta...mentid=2041171http://www.rcuniverse.com/forum/atta...mentid=2041172 |

May I recommend to make another video so we could here the engine in normal flight. I would like to hear it scream as it flies by from a long dive. Thanks Capt,n
|
It sounded OK to me, they were working on hovering the plane a lot and high alpha flying, so they would be down at idle and fast idle speeds and blipping the throttle a lot. Not flying WOT in this case.
|
It sounded to me like it was missing periodically, especially towards the end. Actually, it sounded more like a glow 4-stroke set real rich than a spark ignition gas 4-stroke. But what do I know.
|
I know lots of people are critics here and nothing against you guys but OP keep working on it and do a lot testing then get them on the market. Dont rush to get it out either. make sure its a great product and it will sell.

fg forum is more information, this engine look good. |
Yes you could be right about it being on the rich side, but it seemed to be working OK though.
|
lavagrit, Did not mean to be a critic ....just want you guys to have success with your new 4 cycle engine. It may have a lot of appeal to non 3D flyers. Thanks Capt,n:o
|
new servo launch
we apology for post to wrong place !
|
hello capt,it‘s not my engine,I just think it, cheaper than vm60 and kolm67,and more powerful。
|
@johnlu55 don't profit to SPAM this thread with your CRAP servos. just post more info of this engine.
@lavagrit cheaper for sure but now let's talk about reliability....chinese companies don't have a dyno so your engines power is often FALSE |
I hope they put some care, and love into making the engines. Not just slap them together with a don't care attitude. It tends to cause the quality and attention to detail to suffer. That causes the engines to have stupid problems that should not have happened in the first place.
|
i hope so too. i dont want to discourge them either just want to see new good running engines produced
|
I'd be a little concerned with that intake assy. Would like to see somekind of support for it. Easy enough to fabricate something, but still.
|
Thank you for your comments
We have made continuous testing to make more stable quality |
This motor would fit the bill in the 55-60cc war birds market wich has been hurting for a good 4c gas motor. While the satios are nice, A good 70cc 4c single would fit really well in my war birds.
Do you have a us distribitor yet? |
new video,
Four-stroke engine is more suitable for 3D-fly, faster throttle response and more linear torque curve. https://www.youtube.com/watch?v=j1NUSJDFYJg https://www.youtube.com/watch?v=P3aTn0f1X2g |
