Most of us already know about the turret rotation unit "FIX" and it turns out that fix works for the "elevation unit" too.

For those new to building WWII Tamiya rc tanks Ihave included photos that are, well, worth that 1000 words.

Anyway, I got tired of the hit or miss, poor, weak, operation of the Tamiya main gun elevation unit performance in some of my tanks.

Many builders have swapped out the Tamiya elevation unit for a servo to gain flawless main gun elevation performance and that does work.

Here is another, but far simpler approach: The problem in the elevation unit is a "slipping" clutch gear.

Pull that gear out of the elevation unit and CAGlue it "SOLID" and then re-install it exactly as you removed it!

Again remove the gear first, do NOT glue the gear solid without removing it from the unit first.

Or purchase online from Tamiya the 6-Speed Gearbox H.E Kit. <span class="font-smx">Item #72005: http://www.tamiyausa.com/product/item.php?product-id=72005

Use the exact fitting blue gears found in this kit to replace the unreliable clutch gear.

The BLUE gears work for BOTH the turret rotation unit and the main gun elevation unit. </span>

And for good measures, install a metal elevation arm, replacing the prone to breaking Tamiya kit's plastic elevation arm. Daryl Turner, Impact and others offer this part.

Doing these simple gear glue or swap upgrades will gain you turret operation that works great, and dare I say it, even better than the good turret ops found on my 2 HLtanks.

And the gear you want to glue or replace on the elevation unit rides on the shaft circled "B".
