The main difference between the OS R2102 and the VSR02 is that I have modified sligthly the crankshaft timing and made some extra modifications to the crankshaft itself.
Then I am using my own design combustion chamber(underhead or also insert) which for me brings even more torque to the engine at the low rpm area.
I also prefer to use the steel main-bearing over the ceramic bearing because I have never found more performance over the extra costs.
I have had also very good results using the VSR02 engines with the EFRA 2115 tuned pipes made by Hipex. These pipes give the same performances as the OS2080-SC pipes just less noise. IMO the OS pipes seem more performing but they also make more noise and this has some influence on the racer it seems, but for me the performances are the same.
Great to have you on rctech discussing your engine - thanks.
Can you confirm whether the VSR02 is based on the OS 2102 or OS 2101? I thought it might have been the 2101.
I've like the look/writeups on your engines have been keen to try one. A guy ran one at the Nats last year reported to me that performance was similar to the 2102..which everyone but the winner were running in the final. The OS is very popular here (especially with the top guys) in Australia.
I've been trying to convince my local RC supplier to talk to you to scope out a distribution deal...As I'm unaware of there being one in Australia. But if you have one please advise.
I imagine that now Amain are stocking you, and the current dominance of OS, that your engines will start to sell well.
Good luck and I hope see more VSR02 engine in Australia soon.
P.S. A viable alternative to the OS pipes is welcome given how expensive OS sells then for.
