Owner's instruction manual and warranty card.

Congrats.
Engine looks great. Instructions and warranty are nice.
Wish the engine a long life.
Can you believe that this company makes multi cylinder radial engines?
And i had never heard of it till someone mentioned it on this forum!

Thank you K K Iyer. Yes i'm aware of the multi cylinder radial engine and have been following there progress since start. Warranty is for 1 year (limited) and paid Rs 2687/- shipped which i think is a steal.

UMS25 Rs 2215/- + 14.5% CST Rs 321/- + Courier charges Rs 151/- (Via DTDC Lite Air and fast)

Sure seems good. Waiting for the run report

BTW, how much did it set you back?

Sorry, you posted the price while my post was uploading

how did u purchase it?

I got the contact number ( Ph: +91-422-2243439 Ext: 326 ) from there website ( URL : www.umstech.in ), after calling up i was directed to Commercial Department and spoke to a lady named Sripriya, she requested to send an mail to for further correspondence. After answering all my quires and quotes i sent an email conformation of the order then got a proforma invoice with bank details and i paid via NEFT (off-line). It took 5days to reach me  .

Sanjay after reading instructions my head started to spin. I'm not giving up at, will do a bench setup to break-in the engine    Cox engine is starting to look like a electric motor in comparison to proper glow engine tuning  .........may be because i'm new to this tuning

Planning to start working on the engine this Weekend. Some pics till then

You break-in an engine well and it will never guve up on you . My 9 years old os .46 AX still starts with a single flick and has a great low range , i have almost 5 NIB engines with me (i dont fly nitros much) will find some time one day and break-in all of them . Best of luck

You will be pleasantly surprised how easy it is to start and break in a new glow engine. Just follow the instructions; also do have a quick read on an OS (eg) 46 AX - go to http://manuals.hobbico.com/osm/46ax2-manual.pdf and browse through it

sanjay took a print out of the manual and give it a good read.

Engine looks good. Looking forward to the the run report.  . The carbs are air bleed type right?

Congrats sahil all the best in glow, all glow fans please support sahil he is a gem of a person   ....all the best bro...please keep in touch with micro also ..... thanks for all you support

I only wish it had twin ball bearings instead of bushes

Thanks Roman buddy

Well sanjay bearings would have been nice but considering the price i doubt it. Let see how this whole experience un-winds.

Hi Girishsarwal

Thanks for helping on the fuel part, i don't know if its a air-bleed carb but the instruction provided with the engine does mention of air-bleed screw for high-low rpm setting  .

That engine is a copy of the OS LA design down to a T (or should I say A?). Absence of ball bearing is in a way good, as these do tend to rust. The bushing assuming it is bronze bushed will last a long time, use 20% castor oil, break it in gently and you will have a long lasting engine.    
Are the piston cylinder steel or ABC?
Don't know if any one else noticed the blooper in the parts listing

Hi,

Good to hear from you . I think its ABC piston and awesome man (sharp eyes) spot on cylinder head diagram is missing   

I'm at to get the props and stuff but made the fuel and had run through my cox sure start.

Regards
Sahil

I will send a E-mail to the company people to do the necessary corrections and thanks to manish ji

Could be ABC or ABN, it is easier to manufacture than a great fitting  honed steel cylinder and piston set.
You can check by placing a small magnet next to the piston from exhaust side to check if the piston magnetic material or not
