The thrree-engined Bf110 looks interesting, but I think you've got the center engine too far forward for good weight and balance. I'd move it aft until its firewall is about a foot ahead of the windscreen. Now, the tri-gear variant might need a bit more room to allow for stowing the nose gear, but I'd still move the engine no farther forward than necessary and look at rotating the wheel assembly and stowing it under the pilot.
