First time posting - I find the forum quite useful.
I have a 2015 Radical SR3 RS - its my second radical - my first was a 2012 Radical SR3. The body pins changed between the models and I am struggling with the new pins. I have lost two already (track was quite bumpy, or I could have done it improperly). Has anybody converted to the old style pins? Any suggestions on creating a different method. Or perhaps my technique is just poor with the new body pins and there is a pro tip you can share?

That is a dzus fastener (or a copy), so if they are properly fitted, they should never come loose. My Caterham nose cone was held on with them and all of my race bike bodywork was held together with them and they were 100% reliable despite the vibration. As a safety precaution, you could use a small square of Gaffa tape over the top.

er how do you lose a Dzus fastener? Which bit goes missing?
Good question Bert .......... tape is an added bit of security, but it's certainly not a solve/solution for bodypins that are going missing.There are usually two ways these clips can go missing: a) either the slot head pin has become detached from the retaining self-eject spring (usually caused by someone undoing them who is unaware that 'dzus' are usually only quarter-turn) so just the pin and sometimes its spring goes missing or (more likely in the case of Radical's arrangement) the whole ejecting pin assembly goes missing leaving behind just the circa 25mm hole in the bodywork.
The latter is likely to be caused by the whole ejecting pin assembly being insecurely retained by the star retaining clip and/or not properly adjusted; on my RSX, one of them had no star retaining washer at all and most of the rest lacked proper adjustment; the 'dzu' pin has a coin slot head, but the only way they could be turned/closed was by gripping a coin with a pair of pliers and applying a ridiculous amount of grunt! This can be corrected by carefully adjusting the stationary spring. The star retaining washer is worthy of careful inspection and if necessary, fettling. There are two photos below; the first shows the star retaining clip securing the ejecting pin assembly from the underside of the bodywork; the second shows why because of the quite understandable varying thickness/surface of the underside of the glass fibre bodywork why the seating of that star retaining washer may easily be comprimised and therefore why it can come adrift.
Whilst I totally understand how/why this change has come about on the RSX, imho it is an over ambitious ask to expect 'dzu' fasteners to pin together two very big pieces of 'everyone is different' relatively complex fibreglass, namely at the front, the front bodywork and the front splitter. IMHO, as a fixing solution the use of half a dozen 'dzus' is appreciably inferior to the older models four PIPs which simply pin the bodywork in position, with that bodywork resting on a front splitter that is massively strong and very securely fixed. That said, do safeguard those wonderful PIPs with a bit of tape; at £35 plus VAT & Del a go, best look after them!
