JBA Engines

[mike londke]

A possible substitute for OS engines? Anyone converted one of these to CL with any luck?  http://www.kangkeusa.com/jba.htm?fbclid=IwAR2loxTot_7oaUkOb6r190vnHotbsuxj1MCfMv73Fo41RrMra5mEYEHzryE

Interesting but seem a bit heavy.
The 46 weighs 16.61 ounces - probably with the muffler, which appears massive.
But, someone (maybe Me) will buy one and try to convert it for stunt.

Heavy and anaemic was the general consensus when they came out.

Might be something to play with if you were given one, but I won't waste my hard eared dollars on one.

Well that's enough for me to stay away. Thanks.

But you cant start a thread on how to remove ' the Blue ' , if you dont .

I was most interested in the part where they say the have displacements from .12 and up. I was hoping they had a .25 that would be cheap and suitable for combat. I did call the USA number listed and left a message to see about .25's

Hobby King (I've never ordered from them) has ASP engines, which are known to be pretty decent, so why not stick with them? The one thing all the Chinese engines seem to have in common is the destructibility of the crankshafts if you rev them too high (somewhere above stunt rpm).  Steve

Hobby King has not had ASP engines suitable for CL in stock for a long time. They've been unobtanium for over a year, maybe more. Aerohobby has a supply set up for CL but they are $130. I'm not paying that for a motor that originally sold for $42. I thought the JBA might be a cheap replacement for the lack of ASP stock.

I had an SK 50 on one of their RC arfs. Plenty of power, not sure about the weight. Definitely an OS clone. I've often wondered about the JBAs. Mufflers are very heavy.

Only thing I noticed in the pictures is that they appear to have the "clamp" style carb attach instead of the screws, so converting to CL will take some doing to get the NVA at the correct height.
