I like my R90 SE that I converted to FBL.

But I am tired of paying $6 per flight in fuel costs (Rotor Rage 30% is $30 / gal and I get 5 to 6 flights per gal). I fly it very rarely anymore, and that is a shame.

So, I want to use a OS GT15 w/ the PowerBoost pipe and swap out the YS 91SR 3DS.

I know that the GT15 and the YS 91SR-3DS are not comparable in power out put, but I don't fly the R90 to the same level that I fly my Trex 600N.

Has anyone tried this yet?

I've got all the main gears and pinons that TT made for the R90. That means I can change main GR as needed to keep the head speed close to 1900 with the 16,000 RPM that the GT15 uses (about an 8.4:1 GR).

And, I figure I can find a fuel tank that is 1/2 the capacity of the stock R90 tank - and still keep the flight times in the 10 min range while reducing the weight.

Believe 1/2 of what you see and none of what you hear.

Hope you have a very smooth R90. The GT5 does not like vibrations, but it can be adjusted to tolerate normal levels.

Search the forums here, Gary Wright and I written plenty w regards what to do.

leaving my moment of senility behind

The power available will be similar to a flying an older 60 size glow engine if you are familiar with them. Plenty for big air, classic aerobatics. A good set of stable and efficient FBL blades (Radix, Rails) will help.

I contemplated doing this mod to one of my Freyas but ran out of resources to do it.
