Ive seen a couple Tekno truggies running the backflips without any fittiment issues, but it's all about the wheels, not so much the tires. When I set my ET48.3 up in"monster truck" mode, I have the Proline Badlands MX, Super Swampers and Trenchers, all with the 1/2" offset and the suspension bottoms out before the chassis hits on all but one set and I've had no problem launching it 30 feet on a couple jumps on the track, getting well over my 6' 6" head in the air. Im not sure what the diameter of the Backflips is, but my monster truck tires range from about 6.3" diameter to just over 6.9 and the chassis only lightly taps with the 6.3" set and a big drop. I also installed the 2mm offset hubs when I built it a few weeks ago as I was told they were required when running the proline 3.8", 1/2" offset wheels/tires, and like others have said your MT410 comes with them and I think we have the same arms too. I actually think that the shock package on these Tekno's does an awesome job of stopping the truck from bottoming out hard on the shocks if you have thick enough oil and the right piston/spring combo. I run orange springs all around for monster trucking along with the stock ET48.3 setup oil. I also have the concave delrin pistons and aluminum caps/guides and ti coated shafts as I'm not sure what all comes with the MT410 but I think the shock length is the same?? I would be a little more worried about it if I were running my shocks vented like my SCT410.3, but when they are fully sealed it really would need to take a huge drop to bottom them out enough to damage something. I will say that in 30 years of buying/building/running rc kits, the shocks on my Teknos are easily the best I've ever had and I'm not at all concerned about blowing them out. If you are still worried about it, you can make your own limiters out of nitro fuel tubing putting a small piece on the shock shafts outside of the shock body to limit how far the shocks can travel upwards. I've also used the tubing inside the shock bodies to limit down travel on vehicles without drop screws or to slightly shorten some shocks I put on my crawler. You could also play around with which holes you mount the shocks with on the towers and arms. I haven't with any of my Tekno rigs yet, but with my Losi 8ight E 4.0 I can actually change the droop/rideheight/upward travel quite a lot by just changing around the shock mounting holes. You always need to make sure your drop screws stop the arms before your shocks do though as that can save you from possible problems.
Long winded response, but Im sure you'll figure it out. Happy Bashing!
