[/b]Technoavia SP-91 (same design as Interavia E-3) Russian advanced aerobatic trainer
This was designed late in the Soviet period for use specifically as an high performance trainer in the DOSSAF flying club system (the stalwart, all purpose, Yak 52, A relative dog, having been previously used for the purpose), with the most promising pilots graduating to the Sukhoi 29 two place competition A/C, too expensive and fragile by comparison to the SP-91. The designer was Sergei Yesahan, who also designed all of the Sukhoi aerobatic airplanes which established a winning dynasty at the WAC in the eighties and nineties. The design was finished just as the USSR collapsed. Initial market optimism led to production at two sites in Russia, with planned sales worldwide. Recession led to market failure and only several dozen were built.

My A/C was purchased new in 1995,and shipped directly to the buyer in FL. The buyer only flew it perhaps ten times, before he went on to "hydraulic lock" the engine, bending the #5 link connecting rod. The A/C sat in his hangar until I bought it from his widow in 2012, and installed a spare M14-P engine I had. The A/C is sometimes called "the Aluminum Sukhoi 29" because of it's lineage and appearance but it is heavier, more rugged and has less vertical performance. Roll rate of 330 degrees per second. It also has drooping, cockpit controllable (-1,0,3,6,9 degree) ailerons and is convertible to a single place plane by decking over the front cockpit and use of a single place canopy.

This is a very serious, mil-spec A/C equipped for aerobatics. It has maximum limit loads in the single place version of +11g and -10g and has redundant wing structure with multiple spars. It is easy to fly and capable of using short, poorly prepared, fields.
It is used for glider towing and touring in Europe and may have an European type certificate (experimental exhibition in USA).

The engine has had the commonplace auto spark plug conversion kit and also Barrett hi compression Pistons and rings yielding ~380hp.

That is cool.

What is the fuel capacity without the removable tank?
Is the start air provided by a SCUBA bottle externally or can you mount the air tank to the plane?

Fuel cap. 31 USG. Plane has internal 3 L bottle that is good for 2-3 starts before refilling from ~ 500 psi ext source.

I do have the originally installed engine driven air compressor. I removed it to save the added weight (approx 20 lbs) and power loss (approx 10 HP). A person could purchase an 11 L spherical bottle to replace the existing 3 L bottle and justify running the compressor continuously.

What's the difference between a SP-91 and a SP-95?
