This Revo 3.3 has good compression. Came in a hobby store purchase.Very Clean. Seems like someone started rebuilding it, and gave it to the hobby store. Noticed a broken exhaust and fuel tank missing cap spring. Has a receiver but no transmitter or starter. No body. Great project to finish.  no refunds or returns due to the nature of the hobby so starting auction at .99 Thanks for looking. Good luck.
