This was mentioned in the SpaceX Grasshopper thread, but not here.

LV engines
The ROSSIYANKA LV have new-generation reusable, highly reliable liquid-fuel rocket engines burning eco-friendly fuel components “liquid oxygen + liquefied natural gas”. Besides, application of engines on “liquid oxygen + kerosene” is under consideration now.
Control system
The primary investigations showed the possibility of the development of onboard control system equipment (BCSE) with the performance required. The radio inertial BCSE based on that of SOYUZ-2 was adopted as basic for the 1-st and 2-nd stages that will allow to fulfill the requirements for payload injection and 1-st stage recovery with soft landing on a prepared 50х50m site located 3-5km from the LV launch pad. The high recovery accuracy is provided by the GLONASS satellite navigation system and additional onboard navigation equipment.

Interesting. Thanks, Danderman.

Hum... This was posted on the Makeyev website a long time (several years) ago... An example of "old news" :(

I just found out about this (from the comments of this article (http://www.thespacereview.com/article/2696/1), which I had reached (https://www.reddit.com/r/spacex/comments/2w6dfy/the_space_review_reusability_revival/) by searching the SpaceX subreddit).
According to fregatepallada (the comment is in one of the reply chains to ExPat):
"in 2007 Makeyev State Rocket Centre proposed, a concept with vertically lainched and vertically landed first sttge - it did not have approval by Russian Roskosmos think tank TsNIIMash at the time as being too risky - it had been rejected in 2011 tender in favour of Angara-Baikal LV concept."
So they preferred winged flyback instead of vertical powered landings because the latter was "too risky."

Yep it was my comment :) Unfortunately neither concept - no VTOVL nor VTOHL did not get funding ...:(
