Queen Bee to TD09 Pis/Cyl question

Queen Bee to TD09 Pis/Cyl question
I've seen references to guys modifying the .07 Queen Bee by putting TD 09 pistons and cylinders on them. I understand a crankpin bushing needs to be machined but what are you guys doing about the stroke. From what I can see the 09 has a longer stroke. If its not compensated for doesn't it mess up the port timing?
What do they run like with this mod?
Or is it just a, "Guess what I did" mod?.....
Thanks,
Mike

I personally haven’t done it, I’ve just seen other people online do it before. Not sure if it would mess up the stroke, I know it’s a very very similar cylinder, not sure on the porting though

Re: Queen Bee to TD09 Pis/Cyl question
Like that link, I keep seeing references to the mod but no concrete data. I would have thouhgt that guy "ampabuser", or something like that, over on RCGroups would be all over this mod but he seems content to ring out the stock 07 for all its worth.

Re: Queen Bee to TD09 Pis/Cyl question
Can try a turbo plug adapter for more QB power with a pressure tap.
https://kamtechnik.com/product/ktk-19/

Cox Queen Beast .074 / Kamtechnik Turbo Plug Adapter Test
Works with the .074 and .09 engines
Static Peak 19,783 rpm / .214 hp - 158w / 56.2 mph pitch speed
Impressive 23.3 oz thrust!
OS P4 turbo plug / 25% nitro / 20% oil
This is now a viable power house well exceeding the TD .051
The best bet with a TD .09 is to source a Cox or Tornado RC carb or mod a carb to fit or
rob a throttle sleeve off a Medallion.
