FLM Ofna 250 Mid Tank Build

Reading up on other Mid Tank mods to the HPI Savage - some have stated that the truck becomes front heavy - with the larger 250cc Ofna tank I'm going to use - I expect this will be the case for me - so I've gone ahead and decided to move as much weight to the back of the truck where I can - which has meant moving the receiver battery location.
 
I ended up getting a CEN Fun Factor radio box from eBay and I think this will work - I plan on mounting using the 3 holes shown in the photos below - the radio box will need some modding but it is long enough to keep the HPI LED battery strip:

I think moving the receiver battery to the back of the truck will also give some more options to secure the fuel tank at the front without the battery getting in the way.
 
I was also playing around with the throttle linkage - and have had to do the following:

- Put a bend in the brake rod to move it out away from the chassis slightly
- Reduce the size of the plastic throttle carb mount by cutting it but making sure there is still enough length for the throttle rod to thread into
- Reduce the size of the throttle spring on the throttle rod by clipping some coils away
 
Some new fuel tube arrived in the post which is great news - the thing I am still not happy with is the LRP on the 17t clutch bell - it still feels like the engine is slightly at an angle and not completely parralell with the TVPs to get the mesh right - by slightly getting the engine to turn in towards the center is having a negative imapct on the overall mesh - anyone else experienced this before?

The HPI 4.1 with the purple head in the photos above is on a 15t clutch bell and the engine mount fits square on.
