Where to purchase E and higher motors in Europe? No more Sierra Fox?

    Hi,
    Last year I posted about my trip to Slovakia and asked where to purchase larger motors in Europe. It seems every hobby shop sells Estes and Klima kits and A through D motors, but no E or higher motors. Sierra Fox in Italy was suggested, and indeed they were then selling higher powered motors. But I just looked at their website and it seems now they also are just selling A-D, see http://www.sierrafoxhobbies.com/en/4-model-rocket-motors.

    What happened, have the regulations changed? Is there any other EU source for E and higher motors?
    Thanks,
    Bill

    I'm not privy to details, but apparently the CE certification for the motors expired and is in the process of being renewed. This process needs to be finished, before the motors become available again.

    Thanks for the reply. Certification expired for Sierra Fox or for Europe in general? Is there any other vendor besides Sierra Fox?

    The CE certification expired for ATs in the EU. Given that CTIs were certified a couple of months earlier, they might also be affected, but the current situation with CTI is more complicated and I don't have information regarding their certification status.

    I see that Sierra Fox is once again selling high power motors, so it seems the certification issue has been resolved.

    Is Sierra Fox the only source in Europe for high power motors? Are there any other shops?

    There's a local dealer in Switzerland (Spacetec) but I don't know if he can ship motors.

    Besides being a dealer, Spacetec is the exclusive European importer for AT. Another dealer that opened for business not to long ago is https://eurospacetechnology.eu/. They appeared around the same time when Rebel Space became defunct.

    Thanks for the info. Spacetec has a website in German and English, but it has not been updated since 2013, are they still in business?

    I did see the Rocket World page, https://eurospacetechnology.eu, the web says all AT motors are out of stock, only casings are available. They do show some CTI reloads in stock.

    Spacetec is still around, but sometimes hard to reach.

    Spacetec is the wholesaler for Aerotech in Europe, including UK I believe. He is the one holding the CE certification for all the motors. Tha certification expired early in 2017 and all recharges were banned from sale immediately. After a while they got permission to clear the inventory (that's why they are back on sale) but not to import new motors. We are basically stuck there here in Europe. Certification is expensive and nobody wants to put forward the cash. There are lauches upcoming in Spain Germany, Italy and other places (no idea about UK) and no motors for the rockets. Now Klima clusters are becoming very popular!

    Thanks for the info. What about CTI, is there also a certification issue? Rocket World is showing availability for CTI reloads. Has Klima ever considered making larger motors?

    I have 'heard' that Klima got a big order from the german army for signalling rockets. And these will be powered by 29 mm single use motors. So hopefully in few years we will get plenty of the stuff. CTI reloads were sold by Rebel Space who went out of business and had a so-so reputation. The new guys that picked up the business 'might' have the same problems. CTI basically has no credible resalers in Europe.

    A 29mm Klima would be great. Thanks for the info, sounds like I better order from Sierra Fox before they are out of stock.

    I ordered some F and G Aerotech motors from Sierra Fox and successfully launched today in Slovakia. Also had success with a 2xD9-5 Klima.

    I've noticed that the ejection charge on Klima motors seems to be substantially weaker than the charge on Estes and AT motors. Can anyone confirm this?

    I have used few Klima D9 with very powerful charges! One burned the parachute and another one popped out the motor, damaged the rocket and burned the parachute.
    My guess is that it's unpredictable, some batches have very hot charges and some other have weak charges. Probably you should test one motor with a strong and heavy rocket first, just to check out the charge power of the batch.

    That's interesting, thanks for the reply. I have had the opposite problem, three times at ejection the nose cone popped off but the chute stayed partially inside the body tube. Twice the chute eventually worked its way out but once it stayed in and there was a pretty hard landing, cracked a fin. I thought I was loading the chute incorrectly until I realized there were no deployment issues with Estes and AT motors, all 3 problem flights were with Klima motors, 3 different rockets, all rather large for an 18mm motor.
