"Springtime for Hitler and Germany ", a comedy masterpiece!

My Irish father was the same, a left handed left footer, the teachers wouldn't let him write with his left hand and as a result he was semi-literate.

You need the motor manufacturer's specification. This will tell you the max current the motor can accept without smoking. There may be 2 ratings, one constant and a higher one, time limited. The 5045 refers to the diameter and length of the motor can (although some manufacturers quote the diameter and length of the wire wound stator inside). Do not exceed the motor's current capacity. Choose an esc with a higher capacity than the motor, for example if the max amps for the motor is 40 amps, use a 50 amp esc or higher. The motor manufacturer may recommend different size props for different battery voltages, e.g. 10x6 for 3s, 8x6 for 4s, generally the higher the battery voltage the smaller the prop for a given motor/kv value. I normally do the following: Determine what prop size I require. Define the battery voltage. These 2 parameters will define the approximate kv value I need. Determine the power/weight ratio required for the model, this (together with the battery voltage) will give the max current draw the motor must accept. I then look for an appropriate motor with the correct voltage, current and kv rating. The esc is then chosen to give some amp headroom. eCalc allows you to play with motor/prop/battery combinations to be explored without the expense of buying different combinations.

Indeed. The printer may only recognise sd cards and sdhc cards, not sdxc cards. Sd up to 2gb Sdhc 2 to 32 gb Sdxc 32 gb to 2 tb Sduc 2tb to 128 tb Also check how the card was formatted. Some equipment will accept fat32 and not expat.

Looking at the photo's I'm guessing it could be an old 3542 or similar. Replacements available very cheaply. https://www.aliexpress.com/item/1005006159885118.html?spm=a2g0o.productlist.main.35.65c041a9ZJTFQt&algo_pvid=7fe7cb32-0758-4eb5-9abd-dbc6643b650b&algo_exp_id=7fe7cb32-0758-4eb5-9abd-dbc6643b650b-17&pdp_ext_f={"order"%3A"109"%2C"eval"%3A"1"}&pdp_npi=4%40dis!GBP!36.24!6.98!!!330.64!63.66!%40211b430817423771072228460e348e!12000036044556520!sea!UK!0!ABX&curPageLogUid=fnikYwgkt3Cc&utparam-url=scene%3Asearch|query_from%3A

If you are limiting current to 30 amps on a 3s battery, that's around 330 watts in a 2.5kg model that's around 60 watts per pound so performance will be leisurely. Regarding the prop size, what are the motor dimensions (can diameter and length) and do you know the Kv rating of the motor?
