Assuming here you can’t get another centimetre or two just from using longer shoulder bolts and more inner truck spacers. I would definitely add length to the deck, really long hangars make the ride feel super dead and unresponsive, whether science supports this or not Im not super sure, but I feel like im driving an armoured personnel carrier on fatboy320 hangars and pneumatics.

I’d go for a longer deck rather than wider trucks. Are you thinking of just extending the nose/tail or the standing platform as well? If just nose/tail, maybe that’d leave room for inwards mounted motors as well?

I’d go for TKP trucks personally. Wider trucks is just asking for trouble – more clipping on obstacles, more stress on the hanger. If you adjust the angles correctly then TKP trucks are stable enough I believe.

This, if you add like 2" inwards motors prob fit? Ideal for gear drives. Is the standing platform as long as the redember @eBoosted ? If it is im going to save some munneys for it!
Thank you for your opinions!
If we would make the nose and tail longer by 1", we would need to rework both molds, but it would be possible. The idea with the inverted motor mounts is also not bad. We just need to consider, that the decks will get more flexible if they get longer und they can brake easier in the extended areas.
But I would like to answer the question first, if there is a demand for 7" wheels on RKP trucks at all.
I think a poll would answer the question easier.
- extend nose and tail by 1" each
- make that RKP trucks wider
- just use the TKP trucks
- I don’t care about 7" wheels on RKP trucks

Is that a genuine Amass XT-90 connector? Wires look hotter than the connector anyway I guess though.

Is 70c a issue for silicone wires? They are good up to 200c iirc.
Oh you mean the connector sorry
I feel like that’s fine tbh
We changed the bolt pattern for the BPs for the “White Chocolate” deck.
We gained 1" in WB so now 160mm wheels with loose truck setup and 175mm with tight drucks are possible to ride. We are also experimenting with some other truck setups which seems promising.

Here is a video of me carving the Project X at low speed.
Sorry for the bad video quality.
After several rides with the Project X Stiff Deck and many miles of different test riders, I was looking for a way to further improve the carving abilities of the board. After finishing all kinds of bushing / washer variations with different base plates, same angle/split angle, different wheel setups with thin risers, thick risers, angled risers, no risers and loose trucks, medium loos trucks and cranked up RKP trucks, I decided to try a more unconventional approach.
So I started to test different sorts of trucks TKP, RKP, DKP, Channel, etc and tried to combine the best of both worlds together. Stability and carving ability.
If found the RKP rear and DKP front combination very appealing for my riding style. The pro of RKP/DKP compared to RKP/RKP is the turning at low speeds. With RKP/RKP you need a speed of north of 30km/h to carve with ease and have a playful and nimble riding experience. With the RKP/DKP combo you can turn much tighter and have a enjoyable carve from 20km/h+.
So what did I do exactly to achieve the improved turning w/o sacrificing the rear and stability?
- You need different trucks at the same size. I used our 270mm RKP trucks for the rear and 273mm DKP trucks for the front.
- I adjusted with speed rings and spacers the track width in combination with the narrower wheels.
- Since DKP trucks are higher than RKP trucks, you need to adjust the height of the different trucks to prevent unbalance. For that purpose you can work with risers or use different sized wheels. I decided for smaller wheels to get an even more nimble turn and to create that race car appearance.
For a less aggressive turning it is possible to use a TKP in the front and RKP on the rear end. For a even more aggressive turning I’m sure you could use a TKP on the rear end and a DKP on the front end. I will do more tests to figure out what pros and cons each and every setup does have.
Last but not least I took a video for you guys, because I know you love videos.
I hope this inspires some of you to be braver in experimenting with different trucks on your boards to fit your riding style better than before. Have fun!

Here are some pictures of the new bolt pattern. For the “Dark Chocolate” deck we extend nose and tail in addition to the new bolt pattern and have some tests.
Maximum loose trucks and 160mm wheels. Still couple mm air gap.
Maximum loose trucks 175mm wheels. Maximum lean with 90kg /200lbs slightly touch of the wheels. This won’t happen under normal riding conditions, or with tighter trucks. But we will check if we can modify the deck in that area for some mm to be 100% safe.

Here is some footage of the a hybrid version of the Titan ProjectX with RKP truck on the rear and TKP on the front.
So how does it ride? After the adjustments of the track with axle spacers to get the same width front and rear, everything was pretty straight forward. It was exactly like expected somewhere between of the ride with RKP and DKP trucks. You get more stability at higher speed compared to the RKP/DKP hybride, but less turnability. The turning radius with RKP/RKP is about 4m, RKP/TKP 2m and RKP/DKP about 1m. Everything tested with 45° BPs. RKP/RKP with 50-52° front BP lowers the turning radius by approx. 1m.
In general I think the RKP/TKP combination would appeal to more riders than the RKP/DKP combo. But since I really enjoy DKP trucks I think I still prefer the RKP/DKP version. My average carving/cruising speed was about 30km/h in RKP/DKP and about 40km/h in the RKP/TKP configuration. With RKP/RKP it tends to be north of 45km/h because I feel the need of a certain speed to get a nible and agil rider feeling. This feeling you get quicker and at lower speeds with a board that has looser truck setup or in general a shorter deck/WB. Since the Titan decks are quite long, they benefit a lot from turny trucks, higher BP angles or a loose fit. However, if you want to reach the top speed of the Titan boards which is ATM more than 80km/h or even north of 100km/h with larger motor pullies, you might still keep it on a RKP/RKP setup.
I also tested a TKP/DKP AT/ST setup on the Sportster F1, which you can read soon in the following Thread: Meet the Sportster F1 - Titan | Psychotiller | Bustin | eBoosted | Molicel | Venom | Moon | FS | Bestech | Metr | Riptide

Did today some test rides with Bergs and the RKP/TKP hybrid setup.
The tire pressure was a little low so it was not as nible as I like it, but otherwise it was a butter smooth ride. The gear ratio was set for over 100km/h, that’s why I didn’t test the top speed. I really like the Bergs as urban wheels. In my opinion one of the best setups you can ride.
Waiting now for the finish of the “Dark Chocolate” deck to have an A/B comparison on all parts.

Last update for this year.
The new iteration of the Dark Chocolate deck is done. Nose and tail are longer by 1 inch each. Now it is possible to use 8" wheels on loose trucks without getting wheelbite.
We tried a slightly different color this time, so it looks more like hazel nut or caramel swirl chocolate 
It got also skinned and sprayed logo.
First impression pros and cons:
Pro:
I really like the deck/deck shape and it’s looks. The size in combination with slightly concave and the drops makes it very comfortable for long carvy rides.
The power to weight ratio is in the 12S6P SS setup really nice. The Molicel 50A have plenty of juice for ~100km range on urethan and 60km on AT tires.
The max power output is still 12kW (120A per motor) which is more than enough for every situation on the streets.
The combination of the VESC and the MT V2 Remote is a smooth combination and works great so far. It needs more miles for testing though.
We combined in this version the LLT smart BMS with Metr Pro to have a comparison to the DieBieMS and the Flexi BMS. It is set for charge and discharge, so you always have balanced cells and a wide range of monitoring.
Cons:
The deck is in combination with the enclosure for a flex deck too stiff. We need to add more flex to it for the production series.
At high speeds it get’s wobbly on the current setup. I don’t know yet what it is causing the wobbles. It might by the MBS wheels, or I’m just not used to such big wheels on a RKP. However I probably need to try some different bushing setups for the rear truck to fix this.
The LLT BMS App is not stable. it does not influence the BMS function but you get quite often frozen screens. Does anyone have experience with a fix?
All in all it is a great experience so far. I learned a lot about manufacturing, ESK8s, engineering and business in general this year. Unfortunately due to the Pandemic everything is slower than it should be. But I’m confident that we can launch a great product for the next season.
What comes next?
We are waiting for the helical gear drive to arrive which I would like to offer as an option. We are also working on a new enclosure for the White Chocolate deck. Last step is to take the final decision on the production series parts and stress test them for a while in the final setup.
Finally I would like to say thank you to all of you which are following and contributing to this project. Without you guys and the whole community around it never would be possible to achieve what we achieved so far.
Marry X-Mas and a happy new year 2021
THANK YOU!

Nope it’s just a garbage quality app. I think updates occasionally get published on their site. It wouldn’t even open on Android 10 for a while. I only use the Metr app to look at my battery cell voltages now since @rpasichnyk implemented the connectivity
