Static Break-In:
Make sure that Jack’s 29 cc is mounted on at least 6mm/1/4” aircraft grade plywood, and is firmly fixed with 4 bolts.
We recommend a 1200mh NiCad or NiMH battery. Use a heavy duty on/off switch.
For the first ½ gallon of running we recommend a 16 x 8 prop.
For the first 2 gallons of running we recommend a 32:1 mixed ratio consisting of 3 oz./gal. Lawn Boy Ashless Oil + 1oz./gal. Racing Castor.
After 2 gallons we recommend a synthetic/castor mix @ 40:1 mixed ratio. Bel Ray, Mobil 1, or Honda Racing, @ 2 oz./gal. + 1 oz./gal. Racing Castor.
Prop Recommendations for Flying:
120 Size Aerobats- 18 x 6 Mejzlik or Menz
120 Size Warbirds- 16 x 8, 17 x 6, or 17 x 8 APC
We have experienced the best performance with these props and do not recommend other brands at this time.

"The prototype was based on a Zenoah but number two is based on a photocopy Chinese engine that is very similar to the G-26. The machine work is a bit better. Call Jack Canaday with any questions at 816-528-3937."
