We have just doubled the motor selection for Estes ProSeries II and other mid-power rockets!
How'd we do that? You can now put one of the great little Cesaroni Pro24
motors in a 29mm motor mount. It's hard for Model Rocket Shop to maintain the full selection of Pro29 motors given all the "flavours" available so here's a way to use our tutti fruity Pro24 selection!
This engine - or motor adapter - lets you use smaller physical size 24mm motors in models that have a mount for 29mm.
A bit of rocket science knowledge is required... 24mm motors may weigh less so the CG of your rocket may move forward. But maybe this is neutralised by the weight of the adapter? Do the math - or cross your fingers and be ready to run!
NOTE! Because of the need for CE marking the Estes motors shown are not legal anywhere in the EU. Sale, possession, use or even transporting these motors is illegal.
But that unfortunate issue is mitigated by the availability of the full range of Cesaroni Pro24 motors from one to six grain sizes E to H impulse. Some modification of the adapter/model may be necessary for long motor cases. Motor retention should be carefully considered.
The package contains two plastic adapters that slip right into that 29mm mid size mount.
