Free upgradation for your Rotary Engine model
Due to feedback from many customers reporting that their rotary engine cannot be started due to certain technical issues, TOYAN has made the decision to provide a better experience for customers who have purchased these engines. We will repair and upgrade all single-rotor and twin-rotor rotary engines that cannot start normally, free of charge. Additionally, we will provide an electric starter kit (If you have already purchased one one-button electric start, please return it to us as well).
Please contact Stirlingkit for the return shipping address and related info in advance. After you send the engine back, please provide us with the courier tracking number and payment receipt for the corresponding courier fee. TOYAN & Stirlingkit will cover the cost of return shipping and maintenance fees. We will complete the upgrade in about a month to ensure your engine can be used normally.
We apologize for any inconvenience we may have caused and ask that you have confidence in us. We are committed to returning a rotary engine model that starts perfectly.
If you do not have confidence in us and prefer a refund, please return the engine and provide us with the tracking number. We will provide a refund service after receiving your returned parcel.
The newly tested shrapnel of the rotary engine will deform after 30 minutes of violent testing. The difficulty is relatively high. The current plan is to send more spare shrapnel parts to customers as vulnerable parts. Brute force testing runs at high speed for a long time, and customers generally don't do it this way.
